Processing is as important for podcasts as it is for live radio. However, your challenges and your goals are going to be slightly different.

Radio needs to have that larger-than-life sound to stand out. It’s broadcasting and the challenges are much different.

Just for starters, processing for FM has to take into consideration pre-emphasis, limiting, stereo pilot and multi-path. Most radio stations are a combination of music and voice, and the processing needs to bring out the best in both. Consider the amount of time a lot of processing gurus spend listening to one clip from one song to make sure that the cowbells really sound like cowbells when the radio listener hears it (yes, I am talking about Omnia founder Frank Foti).

The processing also needs to be adjusted for a wider variety of content and voices than a podcast.

Could you have the same processing preset for both an FM radio station and your podcast? Not really, because you will not have pre-emphasis or a final clipper to deal with.

But just as many radio stations have managed to get their streams having similar sonic signatures for their FM and streams, developing a core processing recipe for your podcasts and your FM station can and should be a goal.

After all, if your listeners love your radio station and they recognize the same sonic signature on your podcasts, you already have a fan.

One thing both have in common is the objective: To make sure the listener stays with you and loves your sound. Here are five tips to process your podcasts that will do just that.

#1 Test Your Podcast’s Processed Sound in a Variety of Environments

The other thing podcasting and radio have in common is that you don’t know where your listener is doing the listening. It may be in a car, using earbuds on public transportation, or at home, whether it be on an FM radio or smart speakers.

For both FM and podcasting, you have to create a sonic signature that works across all devices and environments. And we highly recommended that you test your podcast’s processed sound across a variety of devices.

We learned from many years of experience that what may sound great in one environment doesn’t always translate to others. In other words, don’t listen on the most beautiful speakers you have and think “Eureka!” The person listening on a really small smart speaker may not have the same experience at all.

#2 Process Based on Voice

Most podcasts are voice-only with only occasional music beds. A podcast should be processed depending on that voice. The processing adjustments you make will be to try to make the voice sound as good as it can.

This is critically important to keep in mind. The podcaster may have a great story but not the greatest voice, and processing can be used to add a bit more “oomph” to that voice or get rid of issues with over sibilance. What type of mic the podcaster uses can also affect how you process the audio.

#3 Consider Your Format and Audience

Your podcast’s desired sound also depends on what type of podcast you are producing.

A fast-paced podcast geared towards a young audience including lots of music beds can be processed very aggressively. But even at that, if you are going to maximize the loudness, it will need to be at a lower loudness level overall, because it will need to fit in with the rest of the content on a smart speaker or other podcasts. Very little irritates people more than audio content that is much louder than other content.

Using that same aggressive type of audio processing on a cooking show geared towards a more mature audience is a mistake. That audience doesn’t need to hear something über-compressed. Your goal with that type of show is probably a much more open sound.

#4 Podcast Processing & Audio Codecs

Processing for podcasting is  similar to processing for streaming. You do not have the same issues you need to deal with in FM processing.

Both podcasts and streams do have the challenges of audible artifacts caused by audio codecs as well. The good news is that you do not have to deal with a final clipper which can cause issues with audio codecs.

#5 Get Intimate with Your Audience

It is also worth considering that podcasting by its nature is a much more intimate one-on-one experience. It is a podcaster sharing information or a story with its audience one at a time. Often people are listening on ear buds. Processing needs to have that intimate feel.

The author is chief engineer of KTIS(AM/FM), KDNW(FM), KDNI(FM) and KRFG(FM).

Artist Experience via HD Radio has been around for quite a few years now, but KTIS(FM) just implemented station logo and album artwork about two years ago.

At the time, the only ways to verify whether or not the images were going out over the air properly were various car stereos (built into the vehicles, so not very convenient for rack room monitoring), or the Sparc SHD-T750 Tabletop HD Radio.

Because the SPARC was the only indoor option, we purchased a few units — one for engineering, one for promotions, and one for the assistant PD.

We quickly discovered, however, the limitations (bugs?) of the Sparc unit. Strange unpredictable caching of station logos (why is the old logo still showing up on my radio?) and apparently no logo or artwork functionality on the HD4 channel. And even though they’re still being sold on Amazon and promoted on Grace Digital’s website, it seems to be an abandoned product that won’t be receiving any updates or bug fixes.

Enter the Inovonics Sofia 568 SiteStreamer+. It is a veritable toolbox for FM/HD Radio broadcasters to make sure that what you’re intending to put on the air is exactly what’s going on the air.

If you’ve used any of Inovonics’ recent equipment, starting with the Aaron 650 and popular INOmini SiteStreamer line, you will recognize the web interface. It’s organized and divided into sections that make sense. The “Now Playing” tab gives you an overview of your signal condition and various alarms, along with the option to tune the audio output of the unit to whichever station you’d like.

What the listener sees

The “Listener Experience” tab is where the real fun starts.

This tab gives an overview of every single active HD subchannel on the currently-tuned frequency, along with all the metadata and Artist Experience images, while also highlighting which image should be currently displayed on listener’s radios.

It will also tell you if your station logo has an “image issue” relating to the requirements specified by iBiquity Digital/Xperi for the station image logo.

On my particular unit, I’m noticing that my HD2 station logo isn’t currently working for some reason, and that my HD3 station logo seems to have an “issue.” This doesn’t necessarily mean it won’t work over the air, but that for best results, you should look into its formatting and resolution, and that it’s totally cleared of all EXIF data before being loaded into the Importer/Exporter/MSAC Client.

The Sofia 568 has many options for audio outputs — analog, AES3, streaming via the web interface, and AES67 via a separate Dante network jack. So far, the most useful of these has absolutely been the webstream. It’s a quick and easy way to verify things are on the air and sounding normal.

Alarms can be configured to send out an email for audio loss, low signal, RDS issues, pilot issues, HD carrier issues, and HD Artist Experience issues. Also, there are four GPOs on the rear that can be configured as any of those alarms for local signaling to an external monitoring or remote alerting system.

As usual, Inovonics has been extremely helpful in supporting and updating the unit for functionality and bug fixes ever since the original purchase. Overall, having the Sofia 568 in our facility has been a valuable addition to our HD Radio troubleshooting, diagnostic and monitoring toolbox, providing much information that was not otherwise available to us.

There’s a new organization focused on supporting the needs of independent radio broadcasters.

The concept of the new Independent Broadcasters Association (IBA) started as the brainchild of the independent radio operator Ron Stone. After sitting in on a session at an annual NAB conference two years ago, Stone walked out realizing that none of the issues covered were focused on independent radio companies at all.

“When you go to those events, you want to improve your organization and sales. It just seemed like everything was focused on the larger companies,” said Stone, who is founder, president and executive director of IBA and also owner 24 stations in five markets as part of the Adams Radio Group. “I was disheartened. And from there, I thought about what an association can do if it is formed in the right way.”

Fast forward to today and the new Independent Broadcasters Association has found support from 1,200 independent radio members. The association’s goals are to provide independent operators with ways to drive revenue and achieve cost benefits cannot be achieved alone. It will also meet needs not be served by other organizations, such as through educational webinars, conferences, access to group health insurance and admittance to jobs board.

On the heels of this, the IBA also plans to roll out a news service for independent broadcasters. “If you go back into the 1800s when [the Associated Press] started, it began as a co-op with other papers,” Stone said. “What we’re trying to do is to have all independents of the IBA contribute stories and images and [make that news accessible so that] any member can use it.”

Stone wanted to make it clear that stations who are part of the IBA are not trying to compete with other umbrella organizations. “We’re trying to take away from anyone else’s organization,” he said. “And we’re not trying to displace anyone else. Ours is highly focused on operational cost and revenue.”

Other offerings include the ability for independent broadcasters to participate in a financial review of their organization. IBA recently announced an association with dk east associates, a media specialty accounting firm, who will conduct a financial analysis of independent broadcasters’ operations. Participation in the financial report is free but stations must be a member of the IBA.

“We see a lot of information about the industry, but typically it only speaks to larger public companies and it is difficult to use in a meaningful way for local operations,” Stone said when the announcement was made. “The IBA was formed to bring shared resources like this to independent broadcasters, along with revenue-generation and cost-saving opportunities.”

For example, the IBA-dk east associates report will allow members to compare and contrast their operations to others of similar size and will provide quarterly data against 2019 to allow members to gauge their own performance against similar operations during the COVID-19 crisis.

Why did Stone see the need for this type of organization now? “Bigger companies have taken control of what is going on in our country,” he said. “They’ve had control since consolidation in the ’90s. And if you look at revenue, in 1996 we were something like a $15 billion industry. This year, we’re a $10 billion industry; compared to 1996 valuations, that’s more like $8 million. So we’ve lost 50% of the revenue that we used to have. Half our revenue is gone.

“We can keep doing the same things and you can see what the next 10 years is going to look like,” he said. “Or we can make a decision to bind together and find a path together.”

The entire radio industry is facing big challenges, he said. If we lose our position in the car, for example, we lose in a big way, he said. “Part of our plans is to create an app so that we, too, can go to the car manufacturers and argue ‘there’s a reason this app should be on your dashboard.’”

Stone said the organization is also in talks to create its own real-time, app-based ratings service.

A look at the IBA’s current board shows a mix of CEOs, GMs and independent owners with a mix of industry attorneys and digital companies serving as board advisors. The 501(c)(6) nonprofit company will require one third of the board to vacate their seat in December 2021 to keep ideas and mindsets fresh. Varied voices are important, Stone said. “We don’t want to see the same board members serving or 30 years,” he said.

There are several ways to join the IBA, one of which includes a way to make membership financially feasible to all stations. One option is a barter-based plan that includes a per station $100 annual fee plus one 60-second daily barter advertising spot. If they choose the membership barter option, that inventory is sold to fund their membership, Stone said. A second option is $600 annually per station with no barter.

Stone believes that the more independent members that the IBA has, the stronger the association will be. “The more members we have, the more voice we have in the matter. There is every reason to have every [independent station] be part of us.

“I want to know that when our generation hands it over [to the next generation], it will be in good shape,” he said. “But it takes every independent to make that happen.”

Longtime broadcaster Saul Levine thinks the FCC’s decision to allow all-digital on the AM band is “a breakthrough,” and he’s encouraging his fellow AM station owners to invest in new equipment and programming with an eye on eventually going all-digital.

For now, the president of Mount Wilson FM Broadcasters Inc. has just spent a quarter of a million dollars on a new AM transmitting system at his oldies-formatted station KSUR(AM) in Los Angeles.

And he has turned on hybrid AM HD Radio as an interim step, making him one of the few U.S. broadcasters to add fresh AM HD Radio service in recent years.

The project involves a new 25 kW Nautel main transmitter and a 12 kW Nautel standby, plus four new 200-foot towers and ground systems.

He said that KSUR has a “significant” existing audience, so he views using hybrid mode as a compromise that lays groundwork for going 100% digital, which he anticipates doing in 12 to 18 months.

KSUR is a Class B directional station with 20 kW daytime power and a translator at 98.3 FM.

in 1959, Levine put KBCA(FM) on the air at 105.1, broadcasting from more than a mile above downtown Los Angeles as one of the first FM stations on Mount Wilson. “I placed FM 105.1 on the air in 1959 when FM set penetration was only about 25 percent,” he recalled. “It was a difficult time for FM, and the station did not become profitable for 10 years.

“I suggest AM owners who do not have a passion for radio and are looking for fast profits get out of the AM ownership business,” he continued. “Ultimately 100% AM digital will prevail and be successful. Initially, we have elected to go with hybrid HD digital/analog technology. The reason is that this allows continued analog listening while making the transition to all-digital AM.”

He said his analog AM sounds good and the digital component “is significantly noise-free, and provides stereo. KSUR 1260 is also simulcast in HD on our 105.1 FM facility with 100-mile coverage from 6,000-foot-high Mount Wilson.”

Levine told Radio World, “I see the recent FCC decision to approve all digital AM transmission as a breakthrough for the AM service [that will] will lead to financially successful AM stations. In my opinion initial operation with hybrid technology is a fast way to generate a positive outlook for the AM band, and lead to 100% digital technology within a few years.

“In the interim, I urge AM station owners to invest in AM with new equipment, and invest in unique programming to provide the audience with a reason to tune in, plus perceive digital AM radio as I did with FM 62 years ago.” He  says if an AM station plans to go to a new format or needs a kickstart, “I recommend all-digital now. But install the digital equipment now,” regardless.

FCC Chairman Ajit Pai issued a statement on the centennial Monday of the famous KDKA broadcast.

This is the text:

“Today we celebrate the 100th anniversary of our nation’s first widely recognized commercial radio broadcast that took place on November 2, 1920. The broadcast, which aired in Pittsburgh, Pennsylvania on KDKA, Westinghouse Electric’s newly established station, relayed the results of the 1920 presidential election and set the stage for a long line of radio broadcasts that have shaped the story of America.

As the earliest electronic mass communications medium, radio has allowed us to listen in on some of the most momentous occasions in American history, from President Roosevelt’s famous ‘fireside chats’ to Dr. Martin Luther King Jr.’s ‘I Have a Dream’ speech.  It has entertained us, from The War of the Worlds to The Jack Benny Program to American Top 40 with Casey Kasem to The Steve Harvey Morning Show.  And radio still keeps millions of Americans company on long drives, enthralls us with coverage of our favorite sports teams, and when disaster strikes, is one of the most valuable resources for life-saving information.

Radio has given us a way to come together in times of strife and times of triumph.

On behalf of myself and the FCC’s dedicated staff, it is my honor to join all Americans in recognizing this milestone. Congratulations to radio broadcasters on a century of excellence. We look forward to the stories that radio will continue to tell!

The DTS Connected Radio platform that Xperi has been working on for some time is coming to market now and will be part of the sophisticated MBUX multimedia car platform, the company announced.

The Daimler MB User Experience, or “MBUX,” is featured in the new Mercedes-Benz S-Class line.

DTS Connected Radio is a hybrid radio system that combines reception of broadcast signals with IP-delivered metadata; the company says it is now available in 48 countries. Hybrid systems provide a transition for a listener from broadcast to internet as a car drives out of range of a station OTA signal.

[Related: “Hybrid Radio Picks Up Momentum”]

The company also said its content comes from 48,000 radio stations and millions of tracks, albums and artist bios. DTS believes it has the world’s largest database of broadcast metadata.

It stated in the press release: “DTS Connected Radio features big beautiful art, comprehensive artist and album information and imagery, songs, playlists, content recommendations, lyrics, local events, podcasts, and more, enriching broadcasts from thousands of radio stations around the world.”

Xperi General Manager of Automotive Jeff Jury described the relationship as “partnering with Daimler to help make what they call the ‘Third Place’ — a refuge between home and workspace — more delightful.”

In a Radio World interview in July, Jury was asked what was notable about the MBUX system.

“First, Daimler [the parent of Mercedes] is not just handing over the dash to Apple or Google,” he said at the time. “They are innovating for their customers. This is a great outcome for the radio industry because it means not all entertainment needs to be behind a car play or android for auto wall.

“Second, the main screen has radio as a separate icon (and apps as a separate icon). This shows that radio is compelling, and importantly, a standalone infotainment source for Daimler buyers. Again, good for the radio industry because radio is a main option, not one of many apps in the dash.”

DTS highlights research that says radio remains a “must have” dashboard feature and reaches more adults 25–54 than other audio sources. Jury said those consumers want radio “to be as rich and engaging as other media platforms and experiences, particularly a mobile experience.”

DTS promotes its platform to carmakers as a global one, compatible with analog AM/FM and global digital radio formats including DAB, DAB+ and its own HD Radio technology. It said the platform enables OEMs and Tier 1 suppliers to create better user interfaces without consuming a lot of data and computer resources in the vehicle.

Xperi is also the parent of DTS AutoSense, which monitors drivers and occupants; and HD Radio.

Chuck Weber, proprietor of Weber Climbing Services in Elizabethtown, Ind., is often asked for an opinion about a tower company or to recommend one. He answers that a company is only as good as its climbers.

Chuck shared some thoughts to help you get more value out of your next tower re-lamp job.

Ask the climbers to do a visual inspection and perform simple repairs on the way up and during their rest stops. It is an opportunity to gather some information that might save you thousands of dollars, so a little prep work may pay off big.

Some repairs, of course, will be limited by the climber’s knowledge and experience, but most will be commonsense.

A little small talk and a free lunch will make that initial conversation easier. You might also put together a small tool bag for the climber to take up. You can find a canvas bag and carabiner clip at a surplus or outdoor supply store.

In Chuck’s personal re-lamp tool bag, you’ll find a two-way radio as well as a cellphone. Never underestimate the importance of a means of quick and easy vocal contact, even if it’s just asking for AC power to check all the bulbs on the way down the tower.

The cellphone is not only a backup to the radio but it provides a camera to take photos of things that need attention and to document work done.

Also put a roll of quality electrical tape in the bag. Choose multi-use tape. It’s the “duct tape for the tower world,” and worth its weight in gold; it may mean the difference between doing a simple repair now and enduring a expensive failure later.

The electrical tape can provide temporary repairs for situations like the one here where an AC cable became separated from a radome heater.

Another “must-have” is a tube of Aquaseal urethane repair adhesive and sealant.

Use it to fix a poor or missing STL connector weather seal, or squeeze it into a poorly fit wire entry in a junction box. Like the electrical tape, the sealant can save you from early failures on many fronts.

In your bag, also include a coiled length of #14 solid conductor THHN wire, three to five feet of it. Rarely has Chuck been on a tower for a re-lamp and not found a section of coax hanging loose. The wire can be cut to length to create “copper tie wraps” that will last virtually forever.

Be sure to include a multi-tool/screwdriver combo, like the ones made by SOG, to tighten cable clamps or remove the base of a broken bulb from its fixture.

Finally, Chuck suggests that you supply extra bulbs to take up, at least one beacon and one side-lamp. Even new bulbs may fail when powered up; a few are bad out of the box.

You want the re-lamp to be done — with all new bulbs, not leaving an old bulb left in place because a new one failed. Having extras is cheap insurance, and any left over can be shelved for future use.

Thanks, Chuck, for helping us get our money’s worth out of the next re-lamp!

Basics Training

Frequent contributor Dan Slentz has been surfing the web again; he writes about a neat site called “Interesting Engineering” at www.interestingengineering.com.

The site offers an “Ultimate Electrical Engineering Master Class Bundle” that comprises five courses with more than 250 in-depth lessons. It promises to provide a solid understanding of electrical engineering tools and practices. The courses teach simple and complex circuits, as well as repair of household appliances; there’s even a course dedicated to the planning, installation and maintenance of solar power sources.

At this writing, the course is offered for $25

Dan adds that he did not have formal education in electronics; his training has come through the “school of hard knocks,” a Radio Shack 100-in-1 project kit, his antique Knight Kit “lab,” and attending programs such as the Sony school for U-Matic tape decks, Christie projection school and the Harris RF school.

He also has learned from reading sources like Radio World, TV Technology, the late Broadcast Engineering magazine and the super new online material provided by the Society of Broadcast Engineers.

By the way, Dan still uses a cardboard three-wheel Radio Shack resistor value guide, because all he remembers of the resistor colors is “But Violet Goes Willingly.”

The first time I saw a USB device with an antenna connection, I said there was no way to have a complete spectrum analyzer on that device; when I saw what it would do, I was hooked.

When you look at the Broadcast Electronics Avatar Test Receiver, you get the same first impression. However, when you load the software, hook up an antenna and plug the USB cable into the computer, a new world opens up.

The Avatar allows you to analyze not only your signal but all the signals on the FM radio band. Here is the list:

1. RF spectrum and waterfall displays of your signal;
2. Multiplex spectrum display;
3. Modulation power (how “loud” the station is);
4. RDS — see all the transmitted information;
5. Instantaneous deviation;
6. Deviation history;
7. Deviation histogram;
8. Audio spectrum: L & R, plus peak and average;
9. Stereo Lissajous display — see the relative phase and amplitude of the L&R;
10. Stereo quality;
11. Audio S/N (even without cutting modulation).

The Avatar’s ability to look at all of those parameters on a computer gives the technician the look-see at what is happening. Much of the work that we perform involves questions like “Am I over-modulating,” “Is someone interfering with the signal,” “What is my RDS sending out” and “Do I have good stereo separation?”

The RF spectrum shows where your signal is in the FM band, and your spectral occupancy. The MPX spectrum gives you a look at your L+R, L–R pilot, RDS and any SCAs you may have. Modulation power shows a relative indication of how loud you are and of course the RDS analysis shows what is being transmitted.

Something I really like is that the device looks for the stereo pilot and if it is not there, it shows the mono signal on the stereo quality signal.

Practical considerations

My Avatar is set up with an external antenna in my office, so that I can monitor several of the stations that I contract for. You have to be careful about multipath, which can cause apparent overmodulation to be displayed. For clean measurements, use the RF pickup tap on your transmitter.

I will be arranging a remote pickup site for my unit at one of my backup sites. I would consider two antennas, one omni and the other with a high-gain directional antenna on a rotor. I could then log in with a remote desktop connection and get a good reading.

The Avatar works well on a desktop computer or on my portable laptop in the truck. For this location, I have a whip antenna with a magnetic base, which would give you the same signal as if you were listening on the truck radio.

Using the Avatar for new installations, I’d suggest you do a screen grab and have a reference for future use. I have suggested the Avatar to a group that has a station in Key West, Fla., while their home office is in Valdosta, Ga. With remote access via PCAnywhere, LogMeIn or VNC they can monitor the station constantly .

The Avatar RF spectrum display shows the HD sidebands but does not decode them. Audio is analog. The unit also has an input for the AM frequency band, and can display the spectrum on that band, but the software currently does not support AM station analysis.

You are able to switch between 10 presets that you can program. You are also able to label the tabs with the call letters of the station.

The unit is very small and is powered by the USB cable, it fits easily in your toolbox.

Would I buy another Broadcast Electronics Avatar? At the price of $1,495 it is well worth it.

Have you recently stopped to think about how much energy your radio broadcasts use?

That was the question the BBC has attempted to answer about both its radio and TV energy consumption in a  recently published research report, “The Energy Footprint of BBC Radio Services: Now and in the Future.” The report, which explores the energy footprint of BBC radio services, was initiated to try and understand and improve the environmental impact of BBC services.

The study considered energy use across all available platforms — AM, FM, DAB, digital television and internet streaming — to discover which ones had the largest footprints. The BBC also compared energy use at various stages in the radio chain, including playout, encoding, distribution and audience consumption of content.

“This highlighted the key energy hotspots in the BBC radio system and where best to focus our efforts if we want to reduce our energy footprint,” the BBC said in its announcement.

The research was meant to discover how much electricity is currently used by BBC radio services, the comparative energy use per platform, how this use may change over time and which parts of the system are consuming the most energy.

The BBC found that the total energy required to prepare, distribute and consume radio in its 2018 baseline test was estimated to be 325 GWh, equivalent to 0.1% of U.K. electricity use that year. Of all five platforms, FM was found to have the biggest footprint overall at 100 GWh (31%) and AM the lowest at 25 GWh (8%), with IP (79 GWh; 24%), DAB (65 GWh; 20%) and DTV (56 GWh; 17%) falling in-between.

Not all radio platforms are consumed equally, however. The research found that listening hours on FM and DAB were up to 11 times higher than on AM and DTV. The BBC also calculated the electricity consumption per device hour to find the energy intensity of each platform. This painted a slightly different picture where DTV had the largest footprint at 81 watt hour per device-hour, followed by AM (29 watt-hour/device-hour), IP (23 watt-hour/device-hour), FM (13 watt-hour/device-hour) and lastly DAB which had the smallest at 9 watt-hour/device-hour.

Overall, the BBC found that consumption had the biggest footprint, quite a bit larger than preparation and distribution. Consumer devices used around 73% of the total energy in 2018 compared to 27% for distribution, with preparation using less than 0.1% overall.

“Despite similar findings in our television research, we were again surprised by this result as the transmitter networks for radio services collectively use more power than that for digital terrestrial television,” the BBC said in its report. “However, with the tens of millions of consumer devices which can access radio across the U.K., even low-power audio devices add up.”

According to BBC R&D, the research is the first of its kind to analyze radio energy use. The work piggybacks on the research the company released earlier this year about the environmental impact of BBC television.

The BBC attracts more than 30 million listeners in the U.K. per week through live stations, podcasts and on-demand content. Those radio services are being accessed on a range of consumer devices including smart speakers, smartphones and car audio.

In the Oct. 14 KDKA feature the question is twice asked — including in a Page 21 photo caption — “Did engineer Donald Little invent and fabricate the world’s first transducer for turning record groove modulations into a varying voltage?”

The answer is: Decidedly not. The honor for that advance goes to Gianni Bettini, an Italian army lieutenant who made his fortune in the U.S.A but died and remains back in Italy, having patented electrical recording in 1902.

Bettini took a Berliner microphone, manufactured by Bell’s Western Electric Co. and of the type that went into all the world’s telephones for 100 years (which includes KDKA’s in 1920), pushed a needle through the center of its diaphragm and turned it into a phonograph pickup. Bell, Edison and even disc record “revolutionizer” (no pun intended) Emile Berliner missed it. Had any one of them paid attention we’d have had electrical recording two decades before Western Electric introduced it when they created motion picture sound in 1926 (or was it ’25?).

For Radio World readers it should be noted that the broadcasting business quickly adopted WECo’s 33 1/3 rpm 16-inch disc which inaugurated the quarter-century era of recorded-program dissemination on discs. Interestingly, the four networks — NBC (Red), NBC-Blue, CBS and Mutual (the least heralded yet with the most affiliated stations of all) — engaged my friend Harry Bryant’s Radio Recorders in Hollywood to create what came to be called “transcriptions” for delayed broadcast on the “coast” of shows coming in “live” from New York, Chicago, Pittsburgh and Detroit.

Nielsen PPM encoding is now built into the Optimod XPN-AM processor from Orban Labs, at no additional charge, according to the company.

Users who already have an Optimod XPN-AM can contact the company for information on a free upgrade.

Orban Labs issued a press release saying that stations that are now handling Nielsen PPM encoding via XPN-AM include KHTK in Sacramento, KSL in Salt Lake City, KKYX in San Antonio and WSB in Atlanta.

The announcement included endorsements from Bonneville’s Jason Ornellas, director of engineering for Sacramento, and Aaron Farnham, its DOE in Salt Lake City.

“We are broadcasting HD Radio AM using MDCL that gives us additional power savings [at KSL],” Farnham told Orban, highlighting cost savings of having Nielsen encoding built in. “It gives you the ability to process and then encode so you don’t damage the quality of the encoding.”

The XPN-AM Audio Processor is based upon an AM-optimized version of Orban’s MX limiter technology. Orban highlights its ability to generate greater density with lower distortion, saying this can significantly reduce power consumption for users of transmitters equipped with Modulation Dependent Carrier Level. The processor is available in AM and AM/HD Radio versions.

A Florida AM radio station plans to go all-digital soon, now that the Federal Communications Commission has allowed such transitions.

WMGG is owned by NIA Broadcasting; it’s a Class B station in Egypt Lake, Fla., near Tampa, airing a directional signal via a diplexed array. It has 2.8 kW power by day and 800 watts at night, and airs on 1470 kHz.

The company also owns several other AM, FM and TV properties.

President Neal Ardman told Radio World he is in the process of ordering a Nautel HD Radio transmitter to make the change.

“It is time,” he wrote in an email, adding that he is “not worried” about losing analog listening.

WMGG has an FM translator on 101.9 MHz. Both signals are part of “96.1 FM Caliente,” the radio home of the Tampa Bay Buccaneers’ Spanish-language network.

Entercom and FanDuel will also collaborate on in-depth integrations and co-produce new formats and content. “The partnership brings together America’s #1 sportsbook with the #1 sports audio company in the United States,” the companies said in a statement.

The goal of the strategic partnership is to unite two companies in a shared mission to entertain, engage and inform sports fans around all aspects of the game, the companies said. In addition to creating a new model between a sports gaming operator and sports media platform, Entercom also called it the largest advertisement commitment made in radio industry history.

“We are focused on delivering the best sports betting experience for our audiences in markets where legalized sports betting will be pervasive,” said David Field, president and CEO of Entercom. “The marketplace is growing exponentially and FanDuel is an ideal partner to take full advantage of the influence and reach of Entercom’s robust sports platforms to deliver an even better audio sports experience to our listeners.”

FanDuel CEO Matthew King said that in the two years that it has been doing business with Entercom, it became clear to FanDuel that Entercom’s authentic connection with sports fans is one of the best ways for it to engage FanDuel customers.

“We will work together to offer sports fans access to information wherever, whenever and however they consume content, providing them with the tools to learn and win,” he said.

As widely expected and now reported, the FCC has adopted rules to allow AM radio stations in the United States to broadcast an all-digital signal using the HD Radio in-band on-channel MA3 mode.

At the same time, as a small nod to those who either object or would like FCC to consider DRM as well, the commission noted the interest in “alternative technologies,” aka DRM.

All the arguments in favor of DRM — audio quality, coverage, flexibility, extra services, lack of interference or link to one single proprietary company and the extensive proven record — were not enough for the FCC. They considered that looking at other technologies was beyond the scope of the 11-month consultation.

Some might argue that this was more about endorsing one technology rather than examining in detail what can be done to save AM proper. A fuller DRM dossier was required with laboratory and field results, and this request seems reasonable.

There is one snag though: DRM for mediumwave has been tested and documented about two decades ago. It has been recommended by ITU in 2005 and all the tests carried out all over the world are available openly and freely for anyone to see.

Moreover, 35 stations, soon to be increased to 41, in India, are on the air every single day Their coverage is about 800 million people, and this is slightly more than the one and a half station proving the advantages of MA-3.

The DRM Consortium can monitor every second of these live transmissions every day and this can be checked by FCC whenever they want.

These are facts and not more assertions by DRM proponents. A U.S. lab and real test of DRM in the country, as mentioned by the FCC, would be useful but would not change the laws of physics. With FCC support and that of North American broadcasters and broadcasting bodies this could be easily achieved.

In conclusion we feel that, for now, FCC has taken a positive step and sent a good sign about mediumwave revitalization and not only in the U.S.

We know that confrontation has never helped any technology assert itself. Cooperation and fairness have. And DRM is ready to prove its advantages using the opportunity offered by the FCC in their statement.

The DRM consortium remains ready to assist bodies in the USA keen to adopt the system that is finding success in many other countries around the world. This will allow radio on the AM bands to thrive in the digital age using an open competitive system.

GeoBroadcast Solutions is welcoming news that the Federal Communications Commission is taking a close look at its geo-targeting proposal.

Commissioner Geoffrey Starks this week announced that Chairman Ajit Pai is circulating a draft of a notice of proposed rulemaking.

Bill Hieatt, CTO of GeoBroadcast Solutions, called this encouraging news.

“We look forward to working closely with the commission and other stakeholders during the upcoming comment period on the Notice of Proposed Rulemaking to provide any additional information or modeling on the effectiveness and implementation of this technology.”

The National Association of Broadcasters and Xperi have backed the idea of an NPRM. But four of the most prominent radio groups in the United States said earlier this year that more research is necessary before the FCC can seriously consider allowing zoned FM broadcasting.

GBS argues that radio is the only medium that lacks the ability to geo-target content. “This rule change would put radio on par with television, which now has that ability due to the 2017 FCC decision that allowed television broadcasters to use the Next Generation TV standard (also known as ATSC 3.0), one of the many features of which is geo-targeted programming.”

The author is assistant director of integrated broadcast systems for WAMU 88.5.

WAMU is an NPR public news/talk station that services the greater Washington, D.C. metropolitan area.

I came here a little over three and a half years ago from an all-Axia plant in Atlanta. When I arrived, they already had Telos Alliance gear and legacy Pathfinder, which made my transition smooth.

Over time, as I settled into the organization and assessed its workflows, we began to look at its Pathfinder system, which was a bit out of date and needed some love. We put together a grand plan to build a whole new Axia network with Pathfinder Core PRO to freshen everything up, clean everything out and get all the systems nice and neat.

Just as we were about to begin our switchover and start making changes — in fact, only about a week before — the pandemic shutdowns began across the country. This, of course, blew all of our plans out of the water.

Ambitious remote operations

Our station decided very early on to transition to a full remote workflow, and having Pathfinder Core was a big part of reacting accordingly.

We run a national talk show for two hours every day of the week and a local talk show for an hour after that. During these shows, we run through codecs quickly, and in the studio, we had a dedicated person to get people on, connected and checked. We realized that our remote codec position needed some custom help.

For that we turned to Pathfinder Core to build what are called “panels.” A panel is a graphical and functional representation of equipment, signal flows and other functions such as monitoring and internal communication.

We built a panel that allows our codec manager to work remotely and test all 30 to 40 codecs we’ve got, doing line checks and making sure everyone is good to go before show time, and to troubleshoot issues. This was a large panel that I built, and it was a massive help to our operations.

We also built panels for our producers to remotely produce their shows, giving them a real-time feed of the show over a telephone hybrid and the ability to talk to the host, engineer or codec manager as they need to. The fact that Pathfinder Core allows you to do this with web panels makes distributing them to a ton of producers very easy.

We had 35 people “pitching” during our week of remote fundraising, and web panels allowed our pitch producers to speak to the pitchers to coordinate and cue their segments quickly. We turned our panels pages into a series of short links that make onboarding easier than before.

New way of thinking

The most powerful new feature in Pathfinder Core PRO is the relay combiner in Logic Flow events.

With the codec panel I built, we needed to update Logic Flows with new codec sources and destinations actively. When the codec manager opens a panel, they can choose their current codec, which gets written to the “Talk” button’s logic.

I could have accomplished this flow in the old system but with many more steps. When I started using the new system, it took me a little while to get used to the new way of thinking about Logic Flows, but once I got up and running, I was amazed at how much I enjoy using the system.

Right now, we are running a hybrid system of legacy Pathfinder and Pathfinder Core. Any new panels we need are built on Pathfinder Core, while the legacy system is still handling all of our studio switching and air chain events. We are getting close to the point where we will begin migrating over the rest of the systems, and I’m looking forward to having it all up to date.
