FM translators would be allowed to originate some programming content for the first time, if two dozen radio companies get their way.

The group of licensees, under the joint name “Broadcasters for Limited Program Origination,” told the FCC in a filing that “to serve the public interest with increased program diversity,” both FM boosters and translators should be allowed to originate programming for up to 80 hours a week.

Translators and boosters currently rebroadcast only the primary station’s programming. Boosters, which operate on the frequency of their primary station, have been in the news because they are the subject of a separate proposal from GeoBroadcast Solutions. It wants the FCC to allow limited unique programming on synchronized boosters to allow a new geo-targeted or “zoned” capability. The FCC has been taking comments on that.

But the filing by the group of 24 licenses takes the idea much farther.

Allowing FM translators to originate any local programming at all would be a big change, particularly now that so many stations have them in the wake of the AM revitalization effort. AM stations with FM translators would be included under the proposal.

“The Broadcasters for Limited Program Origination seek a uniform FCC rule change for both FM boosters and FM translators to allow each to originate programming content provided that the primary station is retransmitted for no fewer than 40 hours in any calendar week,” they wrote.

“Further, rather than restrict new uses of FM booster stations to the GeoBroadcast Solutions content-specific programming, an FM booster or translator should be able to split off programming whenever such split programming content serves its listening audience, provided the primary station continues to be rebroadcast on the FM booster no fewer than 40 hours in any calendar week.”

The proposal was filed by attorney John Garziglia of Womble Bond Dickinson. The 24 licensees own 108 full-service stations and 85 FM translators.

The stations believe the FCC should not concern itself with restricting which kinds of content should be allowed.

“As with FM booster stations, the FCC should not restrict FM translator licensees in their programming content decisions,” they wrote. “Some radio stations may choose to broadcast different localized advertisements. Others may broadcast localized city council meetings for two or more communities in their coverage areas. The broadcast of multiple localized high school sports games may be what serves a particular station’s listeners. Another station may broadcast two different kinds of ethnic entertainment programming at certain times of the day.”

While this filing was made in response to the GBS proposal, it is a much different beast.

Indeed, the group of licensees said they “take no position as to whether the GeoBroadcast Solutions technical proposal … is wise as a radio listener reception matter. Such concurrent broadcasting of different content on the same frequency within the same service area may be an interference disaster.” Rather, they wrote, their goal is “to provide diverse programming over FM translator and booster radio facilities without the FCC’s heavy thumb restricting their choice of content.”

If the GBS concept of originating limited separate programming on same-channel booster stations is acceptable “as a regulatory matter,” then so should be the origination of limited separate programming on FM translators.

The companies also argue that, because the commission’s new translator interference rules “have redefined the coverage contours of FM stations,” the extended coverage contours out to the greater of the 45 dBμ contour or a 25-mile radius from the translator site should now apply to what is regarded as a fill-in station for the purposes of the FM translator rules.

And further marking this proposal as a potential big change, the group would like the commission to designate four-letter call signs with the suffix “-FX” for translators that originate limited programming content. “FM translators originating programming will be serving listening audiences just like any other broadcast station,” they wrote.

The broadcasters in the filing are Miller Communications/Kaskaskia Broadcasting; the Cromwell Group of Illinois and Hancock Communications; TBE LLC; SSR Communications; Port Broadcasting; the Fingerlakes Radio Group and Chadwick Bay Broadcasting; Blackbelt Broadcasting; Mazur LLC; The Original Company, Old Northwest Broadcasting and The Innovation Center; Virden Broadcasting; Lovcom Inc.; Genesee Media Corp.; Viper Communications; Mountain Top Media; Eastern Shore Radio; and MTN Broadcasting and Eldora Broadcasting.

Among familiar broadcaster names on the proposal are Randal Miller, Bud Walters, Terry Barber, Mark Lange, Matt Wesolowski and Cindy May Johnson.

Dennis Wharton

Dennis Wharton has been spokesman for the National Association of Broadcasters longer than anyone in its history. But he’ll retire from that role come July.

Wharton, executive vice president of communications, has been with the association for 24 years. Ann Marie Cumming will become the association’s primary spokesperson, and Wharton will continue to serve as a senior advisor, according to President/CEO Gordon Smith.

In an email to the NAB Board of Directors, Wharton described his tenure at NAB as “the privilege of my professional life,” noting he had been “in the catbird seat for countless moments in broadcast history,” including the launch of HDTV, radio performance royalty fights, “wardrobe malfunctions, and media consolidation battles. According the NAB announcement, he’s is most proud of the unparalleled public service of local broadcast stations, on prominent display during the COVID-19 crisis.

Smith called Wharton “a fervent advocate for local broadcasting” and made special note of his enthusiasm and good humor. “We wish Dennis all the best and are fortunate to have him stay on as an adviser to NAB.”

In Wharton’s letter, he praised the NAB board, his co-workers, local broadcasters, state broadcast association executives and reporters who covered NAB through the years. He reserved special gratitude for colleagues on the NAB communications team, which he has overseen for more than two decades.

Wharton joined NAB in 1996 as vice president, Media Relations, and subsequently was promoted to senior vice president in 1997 and executive vice president in 2006. He has overseen NAB departments that include media relations, research and public service. Wharton joined NAB after a 16-year journalism career in Ohio and as Washington bureau chief for Variety, where he covered legislative and regulatory issues related to broadcasting, cable and Hollywood movie studios.

Michelle Lehman

NAB also announced it will merge the association’s communications and marketing departments into a new Public Affairs department, led by NAB’s Michelle Lehman, executive vice president of marketing. In her new role, Lehman will be responsible for NAB’s media relations, public service and research divisions.
She also spearheads the “We Are Broadcasters” campaign and directs marketing campaigns to promote NAB events and activities, overseeing the association’s brand, messaging and digital strategy.

Lehman began her career in Washington, on Capitol Hill serving as press secretary for former Rep. Bob Goodlatte (R-Va.) and then for the U.S. Senate Homeland Security Committee, under the leadership of former Ranking Member Sen. Fred Thompson (Tenn). She also served as associate director of technology policy for a boutique public relations firm, as well as vice president of public affairs and chief spokesperson for the National Beer Wholesalers Association before joining NAB.

Lehman has tapped Ann Marie Cumming, senior vice president of communications, to serve as the primary spokesperson of the organization. In this role, she will be assisted by Zamir Ahmed, vice president of media relations, who has been with NAB since 2011. Cumming, who joined NAB in 1994, will oversee media relations and the research division led by Vice President of Research Dan McDonald.

The FCC has announced a partial waiver of an EEO rule to help facilitate the rehiring of people who lost jobs in the coronavirus crisis.

Its Media Bureau waived the “broad outreach” requirements of Equal Employment Opportunity recruitment rules in certain circumstances. The rules ordinarily require broadcast stations employing five or more full-time employees to engage in broad recruitment outreach for all full-time job vacancies.

[Read: FCC Eliminates Its Own Engineering Division]

“The Bureau finds good cause to waive this requirement to allow affected broadcast licensees … to return operations to full strength once circumstances permit the re-hiring of released employees,” it announced.

“Specifically, broadcast licensees and MVPDs may rehire full-time employees who were laid off due to circumstances related to the ongoing COVID-19 pandemic without first conducting broad recruitment outreach, if they rehire such employees within nine months after the date they were laid off.”

It emphasized that this partial waiver pertains only to employees who were released due to circumstances related to the COVID-19 pandemic.

It cited the “challenging economic conditions directly resulting from the COVID-19 pandemic, including significant layoffs and workforce reductions in the media industry.”

The FCC believes this waiver “will not have a material adverse impact on the commission’s goals of ensuring equal employment opportunity and nondiscrimination.”

GENEVA — As a medium, radio is perfectly adapted to cross national borders — indeed, it does so quite naturally.

Likewise, using the power of radio to bring people together, sharing output and appreciating a shared experience, is a quality of radio, which has been recognized from the earliest days.

If ever radio should have a patron saint, who realized its potential, it should be Oskar Czeija, intendant of Austrian Radio from 1924–38.

He travelled Europe, meeting the directors of other radio broadcasters, and established the sharing of cultural material, including the Salzburg Festival. It was his strong belief that sharing across national frontiers would bring the world together and develop mutual understanding.

HISTORY

One of the key factors of radio is bringing to its listeners a sense of time and place, connecting them to their own communities, but it can also provide a wide window on the outside world, bringing them in contact with ideas, cultures and events which they could not otherwise access. Czeija’s vision still holds good today for the European Broadcasting Union, allowing listeners to access unique material.

The Coronation of Elizabeth II in 1953. It was the first event to be broadcast live internationally.

But content was not always king. When the EBU was founded after the Second World War — at a hotel in Torquay, England, in 1950 — the primary preoccupations were around technical and legal issues, establishing the framework for effective operation. In the first meeting, television was not mentioned, though it was soon to come on the scene.

Content, and therefore some sense of audience focus, soon followed, for with the second meeting of the EBU, it was proposed that some exchange of television programs take place. In words which would not sound out of place in today’s straitened times, the EBU President Sir Ian Jacob, responded, “Nobody should feel discouraged from taking any initiative which was thought in the interest of broadcasting provided that such activities did not lead to other tasks being neglected or to demands being made for extra staff or financial resources.”

Technician Fritz Zvacek is pictured with headphones.

It was an early example of “more with less.” Consequently, there was an experimental link between England and France later in 1950, and then the television medium came into its own with the shared transmission of the coronation of Queen Elizabeth II in 1953.

Two years ago, we celebrated the 50th anniversary of a regular EBU concert series, which has since blossomed into the EBU Music Exchange, the world’s largest concert hall, with around 5,000 hours of output being exchanged across all musical genres. This service, available to members and associates around the world, enhances the schedules of broadcasters with unique and attractive material, from the New Year’s Day Concert from Vienna, to the Metropolitan Opera, the Last Night of the Proms, and — in 2019 — rare archive material from Oasis and a live performance from Coldplay.

OBJECTIVES

Across the summer, all the major European classical festivals are visited on a regular basis, and special topical events are regularly organized, such as a celebration of women in music and, for 2020, extensive Beethoven events.

The history of the growth of DAB radio remains to be written, but it is already clear that it has provided broadcasters in many countries with the freedom to develop new channels, often serving more hard-to-reach audiences of specific interest groups.

The radio industry has been able to move beyond the limitations of FM, and the EBU has played a major part in bringing about the standards, which now constitute DAB. Likewise, at the moment, close attention is being paid to supporting the ongoing presence of radio in cars, and issues around radio reception on new platforms, including voice-activated devices. The recent lobbying with the European Parliament has successfully led to digital radio receivers becoming obligatory in vehicles from the end of 2020.

In defining its strategy for the fast transforming media environment, the EBU has defined four key areas of activity. These are providing members with unique material, particularly for music, news and sport; promoting knowledge-sharing and networking; supporting members by functioning as a hub of expertise; and finally, establishing beneficial partnerships on behalf of members, for instance, with the U.S. tech giants.

The media world has developed in ways that the EBU’s founders would never have imagined, and their thinking —  formed in a monopolistic world — would not have answered today’s challenges. What does not change is the sense that as broadcasters, working together solely to serve the public, we are stronger together. We are stronger together when dealing with third parties, but also stronger together when making the case for public media.

CONNECTION

The first international television link between France and the United Kingdom took place in 1950.

As I write, the world is concerned with coronavirus, and social media is full of opinions. Under such circumstances, who can we trust to give us rational, reliable information, with expert opinion, debate and analysis?

And once we have consumed sufficient news, where can we find entertainment and music, compiled and curated with sensitivity toward how listeners are feeling in different communities? EBU Members are dedicated to responding to these demands for the benefit of the public.

A document from Radio Vienna in 1931 with a photo of Oskar Czeija, intendant of Austrian Radio from 1924–38.

When radio came into being and defined its public purposes, it was agreed that these centered around informing, educating and entertaining. All three still stand and provide a sense of direction for the EBU Members. However, I would add a fourth purpose, namely, connecting.

In a world where people can become isolated, where they need to feel a connection with others who share their interests and humanity, providing universal services, which bring people together is a vital societal contribution. The commitment to togetherness across the EBU to achieve these common aims has endured for 70 years.

Whatever devices enter the market in the coming decades, the human and societal imperatives will remain unchanged.

The Federal Communications Commission took a decisive step this week when it deleted the call signs of two California FM stations and ordered them to immediately cease operations.

The decision came down to a question of character and the ripple of consequences that come from breaking commission rules.

In the case of KAAX(FM) and KYAF(FM), the story started rather benignly when Avenal Education Services and Central Valley Educational Services requested to modify the authorization of their stations from noncommercial educational status (NCE) to commercial stations. A seemingly simple loophole stymied that request: Avenal and Central Valley were not incorporated prior to filing their station operations.

[Read: Alleged Deception Costs FM Broadcasters Their License]

But it was the details revealed in a previous proceeding that contained the bite that lost owner William Zawila his modification requests.

The FCC looked closely at the findings from a hearing in which the permits and licenses of three other FM stations were revoked after Zawila and two other groups were accused of disingenuous stonewalling and various misrepresentations in their dealings with the commission.

In a proceeding that included six stations (including KAAX and KYAF) questions were raised about misrepresentation, failure to maintain a public file and various technical rule violations against both Avenal, Central Valley and Zawila. During that hearing the Enforcement Bureau found that Avenal and Central Valley were not legally formed nonprofit entities that were qualified for a construction permit for an NCE station. Although the two companies filed their applications in 1988 and 1989, they were not incorporated until 1999 and 2001.

But Avenal and Central Valley answered, no, they actually were in the right and were free to attempt to convert KAAX and KYAF — two stations that are located amongst vast agricultural fields in Central California — to commercial stations by merely by notifying the FCC that they were hoping to have that conversation take place. Zawila challenged the FCC chief administrative law judge’s findings in that earlier proceeding. But the commission ruled against him based on lack of evidence.

Now jumping ahead to May 2020, the FCC again found that Avenal’s and Central Valley’s initial applications for construction permits were flawed because neither applicant was incorporated at the time of filing. And neither can fix the situation by simply applying to convert from NCE to commercial status.

Keep in mind that the FCC is watching closely when it comes not only to character but to the willingness to follow FCC rules. In its findings, the commission found that these two entities cannot attempt to correct their initial errors by attempting a conversion to commercial status. Nor can the two hide the fact that the Avenal company that was incorporated in 1999 has since been dissolved, and that the versions of that corporation incorporated in 2003 and 2015 are currently suspended. Same with the Central Valley Educational Services: the company incorporated in 2001 and the version incorporated in 2015 are also suspended.

The final nail in the coffin for the two entities: as of the date of the FCC’s decision on May 1, 2020, Avenal and Central Valley are still not valid California corporations.

All this led the commission to dismiss the construction permit request and the request to modify from NCE to commercial status, to revoke the stations’ ability to broadcast going forward, and to delete the two station’s call signs.

In an-all-caps demand in its letter to the two entities, the FCC said both KAAX and KYAF must cease broadcast operations immediately. But Zawila and company cannot walk away entirely. Until their towers are dismantled, Zawila and the companies are on the hook for keeping the lights on.

The National Association of Broadcasters is giving qualified support to the idea of allowing U.S. FM radio stations to “geo-target” programming using boosters.

It commented to the FCC about a proposal by GeoBroadcast Solutions, which wants the commission to allow FM booster stations to originate programming on a limited basis.

On the plus side, NAB said, “Enabling radio broadcasters to use boosters to location target announcements and other programming would benefit listeners with more relevant, tailored content, including emergency news and announcements. Geo-targeting could also open important new revenue streams for FM broadcasters in the markets for targeted advertising and smaller, local commercial advertisers.”

NAB said zoned broadcasting may facilitate radio advertising by businesses that were previously priced out of advertising on radio or “found that buying spots that cover an entire radio market was not financially sensible.”

[Read: Tech Company Asks FCC to Allow Geo-Targeted Programming]

But the association also told the FCC that the GBS proposal “is not entirely free of potential concerns.”

It expressed a worry about potential interference that, even if confined to a station’s booster cluster, could cause listeners to change channels or reflect poorly on the FM service. GBS has said its field tests showed no “harmful interference” and that the technology can be managed to minimize disruption.

NAB continued, “We also observe potential concerns that GBS’ system currently works only with analog FM service, which could undermine the continued expansion of digital audio broadcasting (DAB, also called HD Radio). There may be potential disruption to DAB in the targeted zones. This issue is not addressed in the petition.”

NAB noted that GBS is working on implementing its system to be compatible with HD Radio and that GBS says it supports digital radio. “NAB strongly encourages GBS to continue pursuit of a remedy for this issue.” But it said that the existing policy permitting digital translator and booster stations “not be extended to include location targeted programming until there is sufficient experience to demonstrate, at a minimum, that harmful interference to other DAB stations is unlikely to occur.”

[Read: ZoneCasting Will Level the Playing Field for Radio, GBS Says]

On balance, though, NAB said the FCC should go ahead with a rulemaking proceeding “to fully vet the technical issues” and provide input on costs and benefits of geo-targeting generally, and GBS’ specific proposal.

“If GBS’ request for a rule change is approved, NAB has no doubt that broadcasters will carefully weigh all the relevant factors in deciding whether to implement zoned broadcasting, and that market forces will ultimately determine the success of geo-targeting and GBS’ approach.”

AETA Audio Systems has announced recent upgrades and new features for its entire product line.

Enhancements include Remote Access Portal, a service that allows technicians to control all AETA products remotely from wherever they are. This tool gives users global visibility to their total pool of AETA codecs.

 

In addition, AETA’s new Bonding capability allows AETA clients to manage streams by splitting the audio signal on two different networks. It’s meant for users who want to transmit high-quality IP audio, even in crowded areas where networks are overloaded.

Finally, VoLTE [a voice over LTE solution] lets reporters benefit from a mobile operator’s high-definition voice service (like a standard phone call) without having to depend on a 3G network.

With this system, the audio quality may not be as crisp as an AoIP connection, explains AETA, but it does ensure staff makes the most of an operator’s “quality of service.” VoLTE safeguards the link, adds the firm, so it’s less exposed to the “hick ups” that are often associated with IP audio technology.

All AETA Audio systems codecs are compatible with AES67/Ravenna and Dante.

During these strange times of Coronavirus there are many old contradictions coming to light and new ones being formed daily.

Ruxandra Obreja

According to UNICEF spokesman James Elder, simple as it sounds, it’s still difficult to get information out to people in the most remote areas or to people who are not online. But we are not only speaking of remote areas on the African continent or areas of the Pacific. According to an article published in the Guardian on April 23, fewer than three out of 15 families in New South Wales, a developed area of Australia, enjoy broadband, making digital classrooms unviable.

ALWAYS THERE

So, teachers have been hand-delivering lessons to Aboriginal students at home because families do not have reliable access to the internet, and many do not have computers for their children to work on. This doesn’t apply to most Australian students, but the worldwide statistics are staggering, nevertheless.

It’s estimated that globally there are roughly 1.5 billion students learning from home today. About half of these have no internet access. What’s more, there are 250 million fewer women online than men worldwide.

But even in these conditions, there is still one platform that “does the trick every time.” And that’s radio, asserts Elder. And this doesn’t refer to distance learning alone. In times of need radio rises to the plate and not just as a virtual teacher but as a valuable source of trusted information, company and fun, too.

One of the contradictions is that, while a lot of the industries have seen buyers and users fall to almost nil (tourism, entertainment etc.), media, and especially radio consumption, has increased significantly.

Some of the big commercial networks are doing very well. Even public broadcasting, under threat recently, has now been acknowledged and appreciated for its valuable public role and place.

Reception of an extended DRM multiplex on a car radio with NXP chipset.

A recent survey conducted by organizations in the United States like Radio Advertising Bureau, Westwood One and Nielsen have confirmed what is evident: Listeners are tuning in massively. They want coronavirus updates but not in excess, while continuing to appreciate the voice of presenters who are introducing their favorite music.

STRUGGLING TO SURVIVE

In other parts of the world such as India, where most community stations are struggling financially, local radio remains one of the only sources of credible information and familiar entertainment.

It’s therefore no surprise that U.S. survey found radio to be even more appreciated for its link to local communities. The term “local stations” covers a multitude of stations, some of whom are small but commercial, others purely community stations, university radio stations etc.

And here comes another contradiction: While local and community stations have, in general, recently increased their number of listeners, their funds — often based on local advertising — have decreased considerably.

In the U.S., the National Association of Broadcasters is encouraging a campaign to help local broadcasters obtain government funds directly or via government advertising.

In the United Kingdom, the chairman of local broadcasting association CMA, foresees the possible failure of one-third of some 300 community stations if they don’t receive help from the state.

For now, the organization has short-term goals. These include convincing the government to treat local stations like local papers and pay for public health messages and acquiring a grant and then a fund to support the production of programs centered on public health content.

While many of these stations should receive the financial aid they need soon, what will they do when we get back to some kind of normalcy?

CHANGE IS NECESSARY

Beyond the Coronavirus pandemic, local stations must reassess their role, technology and content based on the changing habits of their audience. Some local broadcasters have already begun gathering data for their new strategic direction.

Digital plays an important role in achieving success for many of these stations. Money will always be tight so why not use the same analog frequency and have two or three digital DRM programs, maybe in different languages or dialects, while saving on energy?

Or why not use the same transmitter, same antenna and same combiner system to provide more than three channels. This is possible by using the spectrum situated to the left and right of the analog signal (600 kHz) and allows for up to 12–18 DRM channels.

More program choice from one broadcaster or more channels shared by different broadcasters, each paying only a share of the already reduced operational and energy costs, while remaining in control of their individual content.

This leaves more money for producing new, more local digital content or simply a better one with less repeats and with higher production values.

But there’s an ultimate contradiction. While local and community stations are “the radio that leaves no one behind,” they need to follow what the larger players are doing in order to survive.

These small stations, with much less spending power, also need to implement a strong strategy, advanced technological solutions and adapt to the new environment.

Today nobody is immune to change and, with the help of DRM digital radio, local broadcasting can plot a tactic to help them guarantee survival.

Many stations have auxiliary antennas on their towers, but what good does one do when the whole tower comes down?

In the mid-1990s, I was in the middle of a new 50 kW AM construction project in Denver. The 50-acre site was just north of what is now Denver International Airport. 

The four towers had just been completed, the ground system was plowed in and the tower crew had departed, leaving just me and the folks helping me with the transmitter and antenna project.

One day, I and a couple of others on the crew were at one of the tower bases installing the antenna tuning unit when we heard the drone of a reciprocating engine overhead — close! We looked up, and there was a little yellow airplane just a couple of hundred feet above the ground about to fly right into the antenna field!

Just north and east of the site, about three miles away, was a little residential airport that had been there for decades. The folks who lived there had hangars adjacent to their houses and could fly in and out, a pretty sweet arrangement if you ask me. 

Evidently, the pilot of the little yellow airplane was completely unaware that over the past couple of weeks, four 365-foot towers had gone up nearby, although they were clearly shown on the aeronautical charts.

There was a moment of panic as the plane got closer and closer to the towers. We started to run … but which way? If the plane hit a tower or a guy wire, a tower was sure to come down, and one falling tower would probably cause another to fall … and another, like dominos. And then there would be the wreckage of the plane; where would it go?

So after a few steps, we stopped and just watched, knowing in that moment that running was pointless. 

At the last second, the pilot must have spotted the four big red-and-white striped steel structures and turned sharply away, and we all breathed a big sigh of relief. If that pilot’s heart was pounding as hard as mine was, he might have needed a few minutes to calm down before heading into the landing strip.

EXPECTING THE UNEXPECTED

I was reminded of this episode recently as I was considering vulnerabilities and contingencies within our radio station facilities. 

We do our best to plan for problems, failures and catastrophes, but it’s hard to know which way to run. Even putting aside, say, the occasional global pandemic, we can’t possibly anticipate every direction from which business threats will come, or how it will impact the operation.

We plan for power failures, and that’s a good place to start. Commercial power will fail on occasion — that’s as sure as death and taxes — and we are wise to plan for it with generators and UPSes to keep our equipment powered during the inevitable outages.

We plan for transmitter problems. The most reliable of transmitters do eventually fail, or they need to go down for maintenance, and in preparation for that, we install auxiliary transmitters and some means to switch between transmitters.

Often, we plan for antenna problems. If it’s not lightning blowing a hole in an antenna bay, it’s ice loading up the antenna and making it (temporarily) unusable. Or we must remove excitation from an antenna while workers are in the vicinity of the antenna during maintenance or repair work. In anticipation of that, many stations have auxiliary antennas fed with auxiliary transmission lines ready to go on a moment’s notice.

But once in a while, something comes out of left field that we did not anticipate, and we find ourselves ill-prepared to deal with it. 

We’ve all heard stories and seen news accounts of towers coming down in ice storms or as a result of severe weather. Not many stations can afford a spare tower. Or even if a station does have an off-site auxiliary, what happens when there is an area-wide catastrophe, such a tornado outbreak or an earthquake, that impacts both main and auxiliary sites?

Occasionally we hear about a station that is put off the air because of a fire at the studio or transmitter site. That kind of catastrophe usually results in even backup equipment being damaged, by water or fire retardant if not fire and smoke, leaving the station with no way to get back on the air. How do you plan for that?

Radio station transmitter sites are often a target for thieves. One of my sites was recently burglarized. The alarm alerted the chief engineer and the police, and police were on site before the CE arrived. The thief got away with nothing of significance, but oh … what could have happened! We have on occasion had thieves hack their way through walls at some of our facilities. There is only so much you can do to harden a site against theft. How do you plan for the damage and loss of a break-in?

WHAT’S THAT DRIPPING SOUND?

And then there is the stuff nobody thinks about. Here in my office, the building maintenance people were testing the fire standpipe that goes from ground level to the roof. In the process, they pushed several hundred gallons of water through the pipe and dumped it on the roof all at once, where it should have drained away through a network of roof drains and piping connected to the city storm sewer system. 

During the test, however, the volume of water draining through that network was so great that it completely filled the horizontal run of the cast iron drain pipe … and it found a large crack in the top of the pipe, flooding my office! Thankfully my office is at the opposite end of the building from the studio and engineering spaces, but what if … 

Or what if a fire sprinkler head failed, spraying water all over servers, switches, computers and other critical equipment? Who thinks about that? Which way do we run?

There is no way we can plan for every possible failure or catastrophe. We might as well accept that. But that doesn’t mean that we should be resigned to being off the air should the worst happen.

At my company, I periodically ask our chief engineers and engineering managers to take a hard look at every part of their facilities searching for vulnerabilities. Is there a piece of equipment that would, should it fail, take one or more stations off the air? What can be done to plug that hole?

Disaster recovery is big business in this day and age, and a lot of folks have gotten on that bandwagon. Our company has contracted with a nationwide provider that will respond quickly with whatever we need — temporary office/studio space, computers, servers, internet/telephone service, generators, fuel. It’s comforting to have that in our hip pocket. 

Within the broadcast equipment and digital media realms, we are seeing a lot of disaster recovery pitches being made, most using some form of “cloud” hosting to provide backup or even primary service. This removes the “all eggs in one basket” scenario, spreading out the risk across multiple platforms and facilities. At the same time, it unavoidably adds some vulnerabilities, and that has to be considered as part of the risk/reward equation.

The point of all this is that we, as broadcast engineers, have a responsibility to be prepared for just about anything. It requires critical thought, careful analysis and clear communication to those who make the financial decisions. 

Often, it may mean repurposing or repositioning of certain pieces of equipment. For example, in one market, I had a spare but working transmitter that I chose to reposition to a site some 50 miles away, leaving it disconnected but ready, so that should a wide-area catastrophe occur, I would have a working transmitter on which I could lay my hands and use to get one station back on the air.

It’s all about contingency plans, looking for vulnerabilities, considering the possibilities of what could happen, prioritizing based on what is most likely to happen, and coming up with short-term solutions that can be implemented quickly. 

So … which way will you run? How ready are you for the unimaginable?

AND HOW DO WE KNOW WHAT THE “WORST” EVEN IS?

When I wrote the above column, the world was still right-side up. The Coronavirus was overseas news, and while of some concern, it was certainly not affecting the everyday lives of Americans. “The worst” was a tower falling over. A lot has changed since then; “the worst” has a whole new meaning.

Need drives development of technology, which is another way of stating the old adage, “Necessity is the mother of invention.” We have, in the past weeks, run headlong into a high wall of necessity. Thankfully, many broadcast facilities were, to some degree at least, prepared. 

Internet connectivity, VNC and other remote operating applications, and studio/transmitter infrastructures that permit remote operation and facility management are at the core of such facilities. Imagine how we might have gotten through a similar lockout crisis just a few years ago before such technology and infrastructure were in place.

Tune through the frequencies in most markets and it sounds like business as usual. The hits keep on playing, familiar voices keep us company and paid programs keep airing. Look behind the curtain, however, and you will likely find that nobody is present at the studios in a lot of cases.

It is during crises that we learn. I think back to 9/11, to Katrina, Irene and countless other regional disasters and remember how broadcasters got the job done. COVID-19 is no hurricane. It is an entirely different kind of storm. But it is teaching us a lot of things, and broadcast engineers are earning their pay as never before. 

As we emerge from this crisis – and we will – things are going to be different in a lot of ways. We’ll address that in future editions and in an upcoming ebook. For now, keep giving it your best, and above all else, stay well!

Radioline’s Hybrid Radio application is now compatible with Android Automotive OS. The company says the system is the result of close collaboration with Panasonic Automotive Systems Europe.

The scalable Android Automotive OS enables access to on-board apps and services, including Google Assistant, Google Maps and Google Play Store. Radioline says its Hybrid Radio app integrates into this environment to offer a “seamless experience” between FM, DAB+, HD Radio, IP stations and podcasts.

This means users can now access international and local programs, via catalogs and a search engine. They can also locate stations, shows or podcasts saved in their “favorites” list. In addition, the content displays EPG and metadata, offering information like names of shows, presenters and albums.

“This is very exciting opportunity for Panasonic Automotive to demonstrate our competencies in leading edge tuner performance on Android Automotive OS,” said Yoshi Nakao, President Panasonic Automotive Systems Europe.

Radioline has also developed a Full IP radio app (IP content only) that’ll be available in the Google Play Store for Android Automotive OS-powered vehicles. It says some 90,000 radios and podcasts from 130 countries are available on the service.

Close examination of the technical spaces of the studio facility is at the heart of a good due diligence inspection.

The only constant is change; and our industry has had more than its fair share. But through recurring cycles of contraction and expansion, broadcast properties continue to be bought and sold. “Due diligence” — the process of establishing and evaluating suitability and worth — remains a necessary exercise.

Consulting engineers provide a wide breadth of services, which often include plain and simple guidance, a determination of the best path to proceed. We research, inspect, evaluate and then filter all this through our lifetimes of experience, ultimately lining up the decision chain so that our clients can determine whether they want to put ink on the check or pass. 

Conversely, our due diligence for ownership establishes a defensible asking or listing price when a station is offered for sale. 

Few buyers or sellers use their own funds; so almost without exception, this extensive effort is distilled into a written report for many, many parties to review. Ownership, management, capital sources, risk managers, insurers, key staff members, caterers (kidding) … 

Do an inventory of studio equipment and include a good narrative about the condition of each item.

But your report will go farther and wider than you could ever imagine. The broadcast industry may not be as porous with leaks as Washington politics are; but you will be surprised at the number of people, intended and unintended, who will read your erudite prose.

As nothing is ever really lost on the internet, these reports can have eternal life. If your name is on such documents, they must be factual; and if your opinions or judgment are annotated, they should be identified clearly. 

For the sake of your reputation, they should also be as well-executed as you can make them. Think “crisp report writing” as if you’re sending these pages from the battlefield or the daily log of Joe Friday, “Just the facts, ma’am.” 

Even before you leave the office on your field inspection, you should have:

• Reviewed the current station license(s) of the instant property … these are the ones that matter
• Reviewed the technical and ownership history of the station and, if the station is old enough, the PDF file cards from the FCC records.
• Reviewed the online FCC public file.
• Done a social media sweep for surprises, such as a lawsuit, collection effort, problems or kudos regards programming as well as public perception (including signal) that goes directly to “goodwill.”
• Gathered the asset documents, such as the property maps and titles for the station’s facilities.
• Reviewed the lease and contracts related to technical operations. Will the site lease be lost in a year or two, do they own the dirt under their ground system, or do they just have an easement on someone else’s property?
• Read the documents pertaining to rented or leased site facilities. Same with any interference codicils and site-share fees, not to mention terms, lease renewal bonuses, etc., which can have a huge impact on operations.
• Reviewed utility bills. What are the forward going liabilities? Is the plant technically and energy efficient?
• Inspected coverage maps, both claimed and calculated, with population and demographic overlays.
• Reviewed interference calculations and spacing if applicable.
• Reviewed the asset inventory and noted any items that demand a hands-on inspection. Where is that Cadillac Esplanade or Range Rover that supposedly is used exclusively by the CE, or is it really parked in the GM’s driveway for the spouse’s use?
• Gathered contact information and made appointments with knowledgeable parties to obtain ready access to the facilities. I once made a 1,200-mile trip and then was told that I should have made an advance security appointment — cost $300 — to get onto the roof of a skyscraper to inspect the transmitter plant and antenna
• Packed two cameras: a video camera for general sweeping information intake and a still camera for details. Think something like a slow video pan of the transmitter room and a close-up still of the “rat’s nest” of wiring in the equipment racks as amplification. Double up on visuals to CYA in the event of camera failure.

Inventory your transmitter equipment carefully. Check for condition and proper operation within licensed parameters.

Every station is different, usually reflecting the personality of management. So when you prepare to visit the facility, have a specific plan of inspection with goals to gather the needed information. 

Above all, be logical and ready to bring back factual notes, not just impressions or recollections. Everyone has an opinion; your business is to gather as many facts as you can.

ON-SITE

Now we’re at the station, so let’s begin:

• Start your inspection by gathering up exact names, positions and latest contact numbers of responsible personnel, including their FCC attorneys in case you have to reach back for clarifications, etc. Quite often, you have to attribute a statement to a particular party, and you always want to correctly identify these folks. 
• Review with management the assembled material you have, especially any questionable material and circumstances around that material to double-check the accuracy of these issues. 
• Inspecting the physical studio/office is akin to a house inspection, so we won’t enlarge on this effort, but important points that must be addressed include safety issues, space per employee (does it comply with local codes?) and efficient work arrangement.
• We could devote a series of articles to the efficient and qualitative aspects of air/production facilities; this evaluation is a major component of technical due diligence to answer the biggest of all questions: Can the facility function effectively and if not, what’s wrong?  
• Do an inventory of the actual capital equipment at the transmitter(s). There have been some big surprises in my work: a missing, nearly brand-new top-end processor (it had been loaned to another station, which then loaned it to another one of their stations in a different market) … and in another case, a totally different main transmitter “borrowed” from another station because it sounded better.  
• At the transmitter plant, liabilities and capital expenditures have big numbers attached to them, and therein lies information that is most often needed. Can this facility do its job, and how long until the next big investment event? What looms next, and what is your vision of the plan at the two poles — “just sufficient (or barely adequate)” vs. what is “optimal”?
• Possibly the most overlooked concern is how facilities are interconnected for programming and control: STLs, ICRs, internet, satellite, RPU, ISDN, telco copper, tin-cans with string, whatever. And how reliable, effective and hardened with redundancy is this infrastructure? Connection should be 100% reliable, not 99.9%. (One pragmatic CE using the internet for distribution casually mentioned, “We get a few audio hits each day, where we lose programming feed for seconds at a time!”) Silence is the kiss of death on radio, especially when inexplicable and abrupt; the “next-station” button is right there on our steering wheels.

(As an aside, take good care of yourself on these jaunts. Drink plenty of water, eat regularly and well. Don’t overextend yourself. More stations are out there for you to see, and there is always tomorrow.)

BACK AT HOME A good due diligence process takes into account tower paint, lighting and the condition of antennas and transmission lines. A drone and someone with a license to fly it will help.

Unless you’re under the tightest deadline, when you return to the office, write the report Jesuit style: just begin and let it flow, covering the inspection either chronologically or by section. Then go back through, checking your notes to confirm actual numbers. (Was the power supply to the plant 480-volt three-phase, or was it 208?) Polish up your organization, grammar and tense — add what you missed on the first pass. 

Reports of this nature are built essentially on two kinds of sentence: declarative and interrogatory.

For example, let’s discuss the business office part of the acquisition. First, a declarative statement: “Business and sales space is on the second floor, and the usable space (subtracting washrooms, corridors, vestibules, etc.) is 1,200 square feet for 15 cubicles that are approximately 8 by 8 feet, for a total of about 1,000 of that 1,200 square feet.” 

Then, as an interrogative, we pose the question: “Will that be enough if you consolidate business and sales from other stations to this location?” 

You can see where the yin and yang of these reports are built on the two sides of the seesaw.

Once this first effort is completed to your satisfaction and missing information collected and inculcated into the text, your organization has been optimized and your prose falls upon the eyes like a perfect dawn (I think I’m quoting Steinbeck here), let it sit for at least 24 hours.  

Do your final touchup after your head has really cleared. Make a final pass, channeling first your client and their goals, and then a dispassionate reader looking for a document that will allow a considered decision based on factual data and an honest, independent appraisal. 

NEED TO KNOW

Some final general comments about these reports. 

Speculation not based on facts is neither helpful nor appreciated. Without a factual motivation, do not stray from the goals that you were charged with (what are you being paid for). 

Occasionally, you may have cause to include some details you’d discovered beyond the focus of your inspection. The most egregious circumstance I’ve encountered happened after removing a service cover that seemed to have had an awful lot of use (screw heads nearly paint free compared to the rest of the gear). Inside was a notable stash of drugs and weed (very illegal at the time). I put the cover back on and provided a verbal report covering that one point to the prospective buyer.  

Your final filter of review should parallel advice I was given in the military.

For some reason that remains a mystery to me, when my time was up the army really wanted me to stay; and the incentives were great. To show their confidence in me and dangle potential promotion, I was sent to command school. Ordinarily, that set of briefings is for colonels who are candidates for general grade officer. 

So who teaches potential generals what being a general is like but serving generals!  Each of these august and accomplished folks presented an intense 45 minutes on a germane topic. One of these, a fellow who looked like he had been sent over from central casting to play a general, talked about work at a Pentagon level.

At that echelon in making command decisions, “No one is interested in what you think. Everyone has thoughts and ideas. The person in charge, all the people involved in the mission need to know what you know … for certain. Your thinking should focus directly on what do we need to know to make the best decision, and if lacking, what is missing, and how do we find that missing item?”

That experience made for a very interesting two days. It became quite clear to me why these people were generals.

Your final pass should focus on the facts, just as theirs would in your situation.

My word processor here in the office has every deluxe feature you could imagine — spell check, grammar check, word repeat check, composition check. The only thing it does not have is thought check! That’s up to you and me. When the project is complete and if you put out the effort, your best job will be there in the print; and everyone will be well served.

May 5 is more than Cinco De Mayo, the celebration that takes place in many cities across the United States. It is also a special Giving Tuesday event nationwide. It is your chance to lift up local nonprofits, including community radio stations near you.

Giving Tuesday was created in 2012 as a day to encourage people to do support nonprofit endeavors in their communities. Most of us may remember Giving Tuesday as the day that happens later in the year, around Black Friday and Cyber Monday. As with everything in 2020, though, things are changing up.

Over the past eight years, Giving Tuesday has grown into a wider campaign to encourage people to contribute financially, to collaborate and celebrate generosity of others. More than $2 billion has been raised since Giving Tuesday’s inception. Right now, with so many nonprofits in need of help, you can guess money is the most critical conversation.

[Read: Community Broadcaster: Does Music Die?]

With all the issues facing community radio, your station would be forgiven for Giving Tuesday to seemingly come out of nowhere for you. Between remote work, automation system management and helping our wonderful volunteers, plenty of leaders in community media are pretty stretched these days.

Hope is not lost. If you are now scrambling to do something for Giving Tuesday, an email to your donors and social media messaging reinforcing core themes to your ask are a great start. Why should a listener give money to your station during a pandemic? That’s not intended to be a provocative question, but one to stimulate ideas about your relevance. It’s your chance to shine a light on the good things you bring your area, and why you are important to support.

In times like this, your radio station aspiring to raise funds could whip up a case for support to explain to a potential donor why you are raising money right now. For instance, maybe your station is seeing a gap in this year’s operating budget because you’ve had to cancel a big fundraising event or your pledge drive. Or maybe your station needs funds to deploy more staff to cover communities most affected by health and economic impacts of COVID-19. Helping everyone to understand your need is central to good fundraising.

If you are shooting to send out that email previously mentioned, consider targeted messages to your reliable donors and the more infrequent ones. You can acknowledge your regular contributors in your language, and ask less frequent donors to step out with you this time. While concerns about personal finances are natural, those able to give are usually willing and wish to be asked. You may want to craft your message appropriately.

The day before, it would be a good move to meet via video conference with your influential people, such as board members, key volunteers and others who can promote your station’s Giving Tuesday endeavors on the day-of. You can talk with them about your plans, but involve them too. They’ll be crucial to Giving Tuesday success, so lean on them for advice and, of course, reaching out to their own networks for contributions.

If you are feeling a little bolder, doing some livestreaming on social media can be fun. Facebook Live with your station’s on-air personalities can be really enjoyable. You could also consider Instagram Live or Twitter for livestreaming, depending on where your station is strongest and where the best opportunities lie. These livestreams can be fun and give listeners a look at the stories of the people who bring the content they love. However, do not do this livestream without a bit of planning. Like live radio, nothing is worse on a livestream than fumbling and dead air.

Giving Tuesday is going to be a fantastic day for many nonprofits. How great it will be for your community radio station is in your hands.

The Federal Communications Commission has elected to eliminate the Engineering Division at the organization in an effort to, as it says, “streamline the organization of the Media Bureau” as part of the public interest.

The commission plans to fold the work of the Engineering Division into the Media Bureau’s Industry Analysis Division (IAD) due to changes in the duties of the Engineering Division.

[Read: FCC Debuts New Seal]

“By incorporating the work and staff of the Engineering Division into IAD, we can better ensure that the bureau’s technical expertise is integrated more fully into the bureau’s adjudicatory matters and policy proceedings,” the commission announced on April 29.

Back in 2002, the Engineering Division was established to conduct technical reviews of media-related matters, including overseeing technical compliance of TV and radio broadcast licenses, as well as things like cable regulatory filings and license transfers. But as the industry transitioned from analog to digital and from paper to electronic filing, the Engineering Division’s tasks have diminished.

Bringing the engineering team into the IAD division will result in streamlined operations and reduce redundancies in management.

There was no word on whether staff cuts will be made. The date that the move will become effective will be set by its publication in the Federal Register.

Nowadays, many people are playing with the Arduino (and clones) and the Raspberry Pi (and clones), sometimes known as Single Board Computers or SBCs. We’ve even heard rumors lately that they’re starting to show up in some of our broadcast equipment, hidden and embedded down inside the case.

Each has strengths and weaknesses. There’s no shortage of opinion about which is better. If you want mine, the Arduino is better for small machine control applications, and the Pi is much better if you need networking, a GUI desktop, and the buzzers and bells. The Arduino isn’t nearly as powerful, but it’s ideal for a dedicated process controller. Because the Pi is a full-blown (if miniaturized) computer, it’s not as suited for real-time processes. In the end, the choice is yours.

The key question for us is whether it’s reliable. You might say, “I can maybe see a print server or ‘smart’ wireless access point in my studios, but will they work at a remote transmitter site in a corn field?”

Yes, provided you protect the inputs and outputs (“I/O”). Modern microprocessor chips are quite reliable, if you respect their limits. Even if your transmitter is a newer model with logic inputs and outputs, you shouldn’t just connect it directly to the pins on the SBC. You’ve also got to watch your input voltages, regardless of surges. For example, if your SBC’s processor chip is running at 3.3V and you connect 5V to one of the inputs, bad things will happen.

There are third-party I/O boards available for the Pi (traditionally called “hats”) and the Arduino (“shields”). They’re a good place to start experimenting, but most aren’t suited for hostile environments. One analog I/O board that we purchased only had 1K surface-mount resistors between the input terminals and the pins on the A/D chip. That did provide a little protection, but there was no way it would handle a strong surge.

WHY USE AN SBC?

The example that I’ll show you in this article could admittedly be done with a recent-model remote control with network connectivity. The better remote controls — and for that matter, many of the latest transmitters — can now send email or text, offer SNMP control and more. But the biggest advantages to the SBC revolution are:

1. SBCs are ridiculously cheap. You can buy several and keep spares on hand.
2. They’re ridiculously small. You can even get nice cases to make your work look pretty.
3. There is plenty of information online; code samples, “how tos” and more. You will probably be able to find an existing project that will do what you want with only a bit of modification. 
4. You can give your equipment precisely what it wants with “smart” logic. For example, you may need to send your transmitter a momentary command when a long-term fault occurs, but the faulting device only provides a constant closure. (The little Adafruit Itsy-Bitsy, which is Arduino-compatible, is ideal for this, by the way.)
5. If your SBC has network connectivity (the Pi does by default; you can add it to the Arduino), it can send email, and/or you can log into it remotely to check on things.

Besides, what if your existing remote control is an older model? What if it has just been destroyed by lightning and you need something right now while you wait for a replacement? Most importantly, what if it’s a special case that your existing remote control just doesn’t address as well as you’d like? (See again advantage #4 in the list above.)

AN EXAMPLE: THE GENERATOR MONITOR

This is an actual Raspberry Pi 3 B+ project that I’ve installed at one of our big FMs here in Alabama. We use a Nautel GV40 transmitter at both of our 100,000 watt FM sites, and for STLs we have dedicated wireless data links. This is ideal for “anywhere access,” because we can (carefully, with a good firewall and some port forwarding) reach our sites over the internet. 

Briefly, here’s the background: Both sites are located at the top of a hill in relatively remote areas. The dirt roads tend to wash out after a storm or have fallen trees block access. The public roads to the main gates are paved, but they can also be blocked by flooding and fallen trees. In a severe storm event, I’m probably on generator, and it’s going to be a while before I can access the site to refuel the generator. To stay on the air, I want to lower power to reduce the generator’s fuel consumption.

Our remote control units are supposed to be capable of doing what I want, but “programming” them is quite time-consuming. It’s not easy to test your work either, whereas with a Pi or Arduino, I can easily simulate the inputs and confirm that it does what I need. 

Long story short, given my background as a programmer, engineer and inveterate tinkerer, I opted for the Pi at one of these sites — less than $50 from Digikey with the “Noobs” Raspian operating system ready to go on an SD card.

The second site uses an Arduino-type processor, and will actually raise and lower the transmitter power automatically. I use a laptop running Linux to monitor the Arduino, and it sends the email. But that’s for a future article; for now let’s just look at using a Raspberry Pi as a standalone monitor. If one of the I/O pins goes low, it will send an email. I’ve set it up so that, if the generator starts running, the program running on the Pi will send a warning. Likewise, once the generator stops running, I get another email. I can then choose to go into the transmitter remotely to lower the power, if I so chose.

LIMITING I/O CURRENT

The key to protecting your Pi or Arduino is guaranteeing that the inputs never see a “hostile” input. That’s the ideal, anyway; we can at least add enough protection to cover us in most cases. This project uses the K827-PH, an opto-isolator available from most supply houses, including Digikey and Mouser. These are typical LED-in, transistor-out units, with four isolators in a single 16-pin DIP package. We only need one opto for this example, but the others are available for later expansion.

Fig. 1: Schematic of the connections between the generator controller and Pi.

Fig. 1 shows the basic circuit for this discussion. This is a simplified version of what I’ve done at the site mentioned above. The whole purpose of isolation is isolation, so I don’t connect the input on the Pi directly to the generator’s “run” contacts. I also do not take the 5V supply from the Pi; that would defeat the purpose of isolation. Instead, I’m using an external 12V supply (in actuality, a simple 12V wall wart) which goes through the generator’s normally open contacts, through a 3.3K resistor, into the K827 isolator.

Look closely at R1 and C3 at the opto’s input. I’ve determined that this is all the protection needed for this particular site. If you have one of those sites that attracts everything from lightning to extraterrestrials with funny hats, you should improve this. Make the capacitor larger. Add a varistor to ground to clamp any high voltages. Split R1 into two 1.5Ks, instead of a single 3.3K, with an extra capacitor to ground in the middle. Add a ferrite or RF choke on the input. I will leave this up to you.

If the generator starts, its normally-open contacts will close, causing about 3 mA of current to flow through the isolator’s LED. This turns on the transistor, which pulls pin 15 low. All we need now is a little program that will check that pin at intervals (I’ve chosen 60 seconds).

Fig. 2: 40-pin IDE-style connector pinout for the Raspberry Pi.

Fig. 2 is the pinout of the 40-pin IDE-style connector provided for I/O on the Pi. At this point, the Raspberry Pi’s documentation can confuse you: there are actually several different naming and numbering conventions for the 40-pin IDE style connector that is provided for I/O. The python library that I’m using wants the “GPIO” numbers. Note that each input can also be assigned different uses, depending on what you’re doing. For this article, we only need GPIO 22 as an input, which maps to pin 15 on the 40-pin connector.

You can download the ready-to-run python program here. Pull it up in an editor and change the email addresses, password, the email server and port numbers as needed. Once you’re done, save the file as genwatch.py, then copy it onto your Pi. In a terminal, in the same directory as that file, enter the command

“chmod +x genwatch.py”

to make the file executable. Now you can run it by entering

“./genwatch.py”

at the terminal prompt, while still in the directory containing the file. The program will continuously check the assigned pin at 1-minute intervals, sending an email if the generator’s status changes. Press CTRL-C to stop the program.

To test it, momentarily short pin 15 (GPIO22) to pin 9 (ground) on the 40-pin connector. You can use a clip lead or a small jumper wire — but be careful! Some of the other pins are directly connected to the power supplies, and you can damage things if you accidentally put 5V on a 3V input, or ground one of the power pins. The classic boo-boo is accidentally shorting pin 1 to pin 2 on that 40-pin connector; you’ll be connecting the 3.3V supply directly to the 5V! You really don’t want to do that one.

I’ve commented the program for you. Python will ignore anything after the hash (#), so comments are a great way to explain what the code is doing. Again, you will need to put in a valid email address and password, as well as the recipient’s email address and the address of your email server. These are also noted in the program.

Get a Raspberry Pi and play with this. You will want the Pi and the Raspian operating system, which is available for download or pre-installed on an SD card. Python will be included with the standard Raspian Linux operating system, so you should have what you need.

More information is available online. You can do a Google search for “Raspberry Pi python” to see a bunch of examples. There are a host of forums available online as well, from the “official” Raspberry Pi forum to special forums sponsored by vendors like Seeed Studio, Adafruit, and others.

If you’re feeling experimental, here’s an idea: Refer to Fig. 2 for the pinouts and try reassigning that “genrun = Button(xx)” line in the program to different GPIO numbers. Then ground those pins; the emails should be sent. For a more advanced example, consider using one of the spare optos to monitor the 12V wall wart itself, and send an additional email if the 12V power supply should fail. In any event, have fun!

Player Editori Radio (PER) released the Radioplayer Italia app for Italy on April 28.

Originally announced in October 2019, the app, available for Android and iOS, lets some 44 million Italian listeners easily search and access their favorite radio station from a single access point, no matter where they are — even out of the coverage area of the selected station.

FASTER AND SIMPLER

Members of the PER consortium include Rai, Radio Mediaset, Gedi, Sole 24 Ore, RTL 102.5, RDS, Radio Italia, Radio Kiss Kiss, Radiofreccia along with organizations Aeranti-Corallo and Federazione Radio Televisioni, which include most local broadcasters.

According to the organization, Radioplayer technology includes faster, simpler and more innovative access to the universe of audio streaming and on-demand offerings, podcasts and offline content of broadcasters.

Radioplayer Italia claims it will not ask the user to register, will make personal data anonymous, will not track listeners’ movements and will not interrupt listening with proposals of any kind.

Furthermore, the content is guaranteed by the broadcasters who will directly supply their own content and associated metadata.

“Radio is once again proving to be the most contemporary medium, capable of making a paradigm shift even in times of crisis” said Lorenzo Suraci, president of PER.

CONNECTED DEVICES

The automotive industry is also involved. Radioplayer Worldwide has been collaborating many automotive brands to design and develop the next generation radio interfaces, accessible through touch dashboards and voice commands.

The Radioplayer data feed will also deliver the Italian stations’ metadata to hybrid radio interfaces in many Audi, VW and Porsche cars. This allows hybrid devices to automatically switch between DAB, FM, and streaming, to keep listeners locked into their favorite radio stations.

Also, says Radioplayer, information coming from this data feed will enable advanced receivers to provide listeners with personalized radio recommendations, search results and catch-up content, in a simple and “natural” way.

Radioplayer Italia will progressively be available on all connected devices. These include smart-speaker platforms such as Amazon Echo, Sonos, Bose, Google Assistant and will integrate with Apple CarPlay, Android Auto, Chromecast, Airplay, Apple Watch, Android Wear and other technologies.

• Four stars on the outer seal border, which was an element on the original seal of the FCC’s predecessor, the Federal Radio Commission;
• 18 stars on the shield, representing the current number of bureaus and offices in the commission; and,
• The eagle and shield, which identify the FCC as a federal government agency.

The previous iteration of the seal featured a feed line that comes up the middle between a V-configuration of telephone lines. It connects to three horizontal lines, the middle of which connects to two broadcast towers. The other two connect to telephone lines.

Here is a comparison between the previous seal (on the left) and the new seal (right).

The FCC is expected to incorporate the new seal on business cards, stationary, publications, the FCC website and throughout its new headquarters over the next few months. Official use of the new seal will begin when the move to the new headquarters is completed; the move-in date has been delayed because of the COVID-19 pandemic.

“To be sure, Mr. Chairman and commissioners, this is not the time to raise fees.”

So says the leader of the New Jersey Broadcasters Association to FCC Chairman Ajit Pai and the other four commissioners.

Paul Rotella wrote what he called an “impassioned” letter asking that the FCC “hold off on the consideration and imposition of any regulatory fee increase at the next commission open meeting scheduled for May 13.”

He said that an increase in annual fees for broadcasters is not warranted and that “this is certainly not the appropriate time to put any further financial burdens on broadcasters.”

The proposed fee schedule calls for about $30 million in fees collected from U.S. AM and FM broadcasters, up from roughly $29 million this year, according to Radio World’s calculation of the FCC data.

Rotella said radio and TV stations have been particularly hard hit by COVID-19, with severe reductions in advertisement revenues. “Most broadcasters have sustained declines of 60–70% in ad revenues, and some have lost even more over the past two months. Indeed, some have had a vaporization of revenue altogether in the last 30 days. Even if the economy were restored tomorrow, it would take months to generate and invoice sponsor revenue, let alone receive it.”

Rotella said that fee hikes, “especially during this time of catastrophic economic upheaval, coupled with the precarious economic forecasts ahead, is simply imprudent and will likely further hobble local broadcasters’ efforts to survive in the aftermath of COVID-19.

“If these snowballing fees force stations to go dark, there’s no other local entity that could ever replace them.”

The commission is expected to consider fees for fiscal 2020 at its May meeting, a total of $339 million across industries.

Jeff Welton says he was lucky enough to find his dream job not far from where he grew up in Nova Scotia, Canada. 

This year’s recipient of the NAB Radio Engineering Achievement Award joined Nautel nearly 30 years ago and has served the broadcast transmitter manufacturer in several roles.

Welton, 55, regional sales manager Central U.S. for Nautel, is a frequent lecturer and expert on digital radio, radio technology and radio engineering. He has written numerous articles and three chapters in the 11th edition of the NAB Engineering Handbook, and even finds time to volunteer at a local community radio station not far from his home, where he provides some engineering assistance. Many know him for his “Tips n Tricks” presentations, delivered with his warm sense of humor — as captured in the title of one called “How Not to Blow Stuff Up.”

The Canadian has been on a bit of a win streak. In 2018, the Society of Broadcast Engineers named Welton the James C. Wulliman Educator of the Year. In 2019 the Association of Public Radio Engineers handed him the APRE Engineering Achievement Award.   

Radio World asked Welton his thoughts on trends in RF manufacturing and where digital radio is headed in the United States.

Radio World: You spent your first 17 years at Nautel in field service and technical support positions. What is the most important current trend radio broadcasters need to know about? 

Jeff Welton: The biggest trend in transmitter manufacturing is IP connectivity. But most importantly for broadcast is the attendant need for IT security, which people are beginning to be made aware of; but it has been a very slow process.  

At work in 2000.

RW: How big of an issue is the security?

Welton: You have seen all of the news of IT ransomware attacks. There are many more hacks and viruses that happen every day that no one ever hears about. Occasionally I will do an Internet of Things search looking for unprotected devices, and if I search audio codes and search a few of the bigger names in codecs, I will find thousands of units online, and half will be using default user names and passwords. That’s the biggest thing right now for broadcasters to be aware of. 

RW: You’re no longer on the design side of the transmitter business, but where does Nautel see RF design going next?

Welton: You certainly see the trend toward smaller footprints. More power density, more watts per cubic inch, so to speak. That trend will continue, but eventually the laws of physics dictate we just can’t get any smaller. Having said that, the laws of physics can always be challenged, and we will going forward.

RW: Any move by Nautel toward a liquid-cooled design for FM/HD transmitter? Some of your competition, like GatesAir and R&S, have been active in that segment. 

Welton: I really can’t answer that question. No comment. That said, we have looked at liquid-cooling repeatedly over the years, going back as far as at least 15 years ago, if not further. We did a 20 kW design in the late ’90s/early 2000s that was liquid-cooled in the initial prototype. 

Ultimately, at that time, we did decide to abandon it for several reasons. Even today, with the advances in the technology, it’s hard to justify the additional cost of liquid cooling in all but the highest power levels, and even then only in specific circumstances. Definitely there are advantages, but the flexibility and lower cost of an air-cooled system typically outweighs those advantages in most cases. 

However, it certainly is situational. What may be the best cost benefit for a 30 kW station in one market may not apply equally to a similar station in a different market, climate or site situation. 

My recommendation to radio broadcasters is to always get a couple of opinions, then try to sort out what provides the best long-term benefits for your station. 

RW: How about all-digital for the AM band. Does Nautel see promise in that market?

Welton: Definitely, we are behind it and support it as a manufacturer. I think it will be good for the broadcast industry, but I’ll qualify that with one thing. It really all comes down to the content, honestly. I think the technology is great and it has promise, but without the worthwhile content and good programming, it is not going to solve any problems for AM broadcasters in the United States.            

RW: You’re known as the “go to” tech support guy at Nautel, yet your official title is regional sales manager. Tell us more about what you do and how much travel is involved.

Welton inspects a newly installed V5 in Wisconsin in 2010.

Welton: I travel anywhere from 100 to 200 days a year. It can vary quite a bit. I have the formal title of regional sales manager, but I pretty much focus on, as they say, “other duties as assigned.” I do seven to 10 state association shows a year. I do NAB of course. I do a half-dozen SBE presentations and some Nautel-sponsored webinars. I even stop in on sight occasionally to help with HD system installs. So I do get to do some hands-on work still.

RW: So you are out visiting facilities and meeting a lot of radio broadcast engineers. What is the most impressive thing you find about that group?

Welton: I think more than anything you find people who willing to be helpful to others, even their competition. You can find people who are competitors but then willing to help others in an emergency and work together. I’ve found that to be the case even during my tech support days.   

RW: How do you think radio can navigate the problem of losing veteran engineers who have a deep knowledge of RF systems? Obviously this affects broadcasters and how they maintain their RF facilities.

Welton: Well, there is a solution, and it’s hard. We need to get young people bit by the bug. Once you get in this industry it really does get into your blood. You don’t see many people leave the industry once they are in it. Where else can you have so much fun and make a living at it? [chuckles] 

I think the pay scale is coming up a bit, but the big thing is tweaking the interest of young folks. That might be hosting an engineering table at a state show career fair. You have to get the exposure to draw interest. There are lots of opportunities for people to be mentored and work part time while being in school still. That’s a great way into the profession 

RW: You perform presentations every year on topics like lightning protection, grounding, transmitter site safety and various other subjects. Is there a topic out there you want to teach?  

Welton: One of the big ones for me is HD Radio, AM and FM, and the implementation. The technology has developed so that I would like to put together a booklet and really dig in how to install and what to look for rather than the theory of the operation of the technology. Really it would be a practical application of HD Radio. So now that it is out there, I’d better get to work on it.

RW: Nautel has for some time thought about equipment beyond transmitters as a way to grow the business. Any new broadcast equipment coming down the pipe?

Welton: Not much I can say on the broadcast side. Much of the work we do outside of broadcast is non-disclosure since we are dealing with the military. We find lots of ways to keep busy and we do a lot of things in RF above and beyond radio, which is cool.

RW: Tell us something about yourself that surprises people when they learn it.

Welton: That I have a fully functioning wood working shop at my home right outside my office. I haven’t been able to work out in it much since I’ve been so busy with work. The last thing I built was a vanity for a bathroom remodel. I did all the cabinetry and built all of the drawers into it. That was cool. It’s a far departure from electronics

RW: Anything else keep you busy at home?

Welton: I love to cook. I spend a lot of time in the kitchen. I got a pressure cooker last year, and loved it so much I augmented that with a second one about a week later.

RW: How did you get your start at Nautel? 

Welton: We had a speaker at my high school one day for career day talking about electronics school in Toronto. I grew up on a farm in Nova Scotia, so as soon as I heard the word “Toronto” I was hooked. He could have been talking about cosmetology school and I would have ended up being a hairdresser. So I went to Radio College of Canada (RCC) for electronics engineering. 

Then I had a few jobs after that, including doing bench repair at Radio Shack. Then in 1990 Kevin Rodgers (now president and CEO of Nautel) was put in charge of building a customer service department for Nautel. By the luck of the draw I ended up there and have been ever since.   

RW: What were your first thoughts upon learning of the NAB engineering award?

Welton: Really of all the people I need to thank for being where I am today. There have been so many people I’ve learned from. Jack Sellmeyer and Tom King come to mind if you are talking directional AM antennas. Gary Cavell has always been willing to answer my sometimes dumb questions. Mark Persons is always willing to share knowledge.   

The one thing I always try to convey to people is that everybody everywhere knows something that somebody else doesn’t. I’ve just been very fortunate to find a bunch of people willing to share the things they know that I don’t. And there is a long list of things. The more I know the more I realize I don’t know it all. Not even close.
