With a handful of exceptions, including Cumulus Media, radio and TV stocks were largely on the rise as the final trading week of 2020 kicked off on Monday.

Among the gainers: Sinclair Broadcast Group, and Dish, which just resolved its retransmission consent impasse with Nexstar Media Group.

 

RBR+TVBR OBSERVATION

Travel around Manchester, England, and you’ll hear radio stations with the same branding — Radio X, Capital, Heart, Smooth Radio, and Greatest Hits Radio — as other stations across Great Britain.

In Australia, the Nova and KIIS brands can be found in both Melbourne and Sydney.

Now, Canada is swiftly becoming a nation where national branding of radio stations, while retaining their unique program offerings, is being employed to help attract more advertising.

Interestingly, it hasn’t exactly happened in the U.S. — yet.

At Spot TV, GEICO is most certainly one of the stalwarts with respect to ad activity by commercial count.

Indeed, it is No. 2 for the week ending December 27. But, there’s a big new No. 1, and it is a germ-fighting brand.

Gene Loving has enjoyed a remarkable career in radio broadcasting. In the 1960s, his syndicated interviews with The Beatles could be heard on stations across the U.S., as he attracted big audiences for his daily radio program at WGH-AM 1310 in Norfolk.

In 1991, he co-founded the original Max Media Properties, and its current incarnation dates to 2001, when Loving teamed with local TV sales veteran John Trinder and the late Chuck McFadden — a former GM of WTVZ-TV in Norfolk — to build a company that today includes radio stations in the Tidewater region, including WGH.

Now, the ownership partners are shifting at Max, with Loving gaining a greater stake in the company.

It’s thanks, in part, to the departure of a key institutional investor.

It was a largely expected deal. Still, the Media Bureau of the FCC used the time-honored tactic of burying big news before a major holiday to tell the world of its decision.

It has given its OK to a transaction that will see a global private investment firm and a related media-focused operating and investment company take majority ownership interest in the biggest multimedia company targeting U.S. Hispanics.

A radio industry notable has moved forward in forming a “SPAC” focused on sports media. It is an effort sparked by the man who once owned the Seattle Mariners Baseball Club.

But, it also involves the man who serves as President/COO of the company this industry leader founded in 1979, and three board members.

Among those board members: the former head of ESPN Audio, Traug Keller.

For those who were raised in Upstate New York, SPAC is shorthand for a popular outdoor concert venue in Saratoga Springs. On Wall Street, a “SPAC” is shorthand for a “Special Purpose Acquisition Company” — like the one Cumulus Media co-founder Lew Dickey Jr. created for an early 2019 merger with international digital music streaming platform Akazoo.

Now, another radio industry notable of the last 25 years has moved forward in forming a “SPAC” focused on sports media. It is an effort sparked by the man who once owned the Seattle Mariners Baseball Club.

For years, it was safe to say that GEICO was the biggest user of broadcast and cable to reach consumers, given their dominance at spot radio, spot cable and spot TV according to Media Monitors. That’s not true today, as one of its auto insurance competitors has surged to the top of the latest Spot Radio report.

As shown below, State Farm is the big leader at Spot Radio, and accounts for a stunning 94,230 spot plays.

By comparison, GEICO is ranked No. 8 for the week ending December 27, with some 45,757 spot plays detected. That puts GEICO slightly below Progressive in an ever-competitive brand category.

While State Farm is firmly ensconced at the top, Bank of America and Merrill are again major users of spot radio, as is Pfizer — the maker of one of two approved COVID-19 vaccines.

An AM/FM combo serving Minot, N.D., has been involuntary placed into an estate administered by Virginia-based attorney Todd Steiner, following the recent death of the stations’ licensee.

The estate is being led by the deceased owner’s son, who continues to manage business affairs of the properties.

The idea of a broadcast engineer totally retiring does not seem to be working out for me.

I tell everyone I am semi-retired. The theory is to be able to find a few small side jobs to just make a little “mad money” using the skills acquired through a decades-long career. 

But the last few months have demonstrated how this theory never seems to quite work out. 

I live in rural Colorado, about 15 minutes from a four-station FM transmitter site. For them, the nearest unretired engineer is over an hour away.

I’ve just finished installing two transmitters there for K-LOVE/Air1. In the process I learned that fluid-cooled transmitters are not just for huge markets and installed on skyscrapers. This was one of the most complex installs that I have worked on, and the finished project seems like a new level of quality — 35 kW and 10 kW, so clean and quiet they seem unreal.

Just as I was completing the transmitter project and thinking of relaxing again, I got a text from the manager of a college radio station where I have a support contract. Turns out they got funding and had taken delivery of two Wheatstone control surfaces, blades and Cisco switches.

My experience is with small stations that owned good control boards, but nothing IP-based. So it looks like have some learning to do, as this next project gets underway.

If I really wanted to enjoy being semi-retired I guess I should have just gone back and taken a part-time job where I worked in college. Too bad there aren’t many RadioShacks left; that would have been the retirement job for me.

The post Letter: This Is Retirement? appeared first on Radio World.

The author is Colorado field engineer for Educational Media Foundation.

PUEBLO, Colo. — Educational Media Foundation is most often identified with its growing K-LOVE and Air1 brands, which today represent the largest contemporary Christian music radio networks in the United States.

EMF has provided a presence for both networks in Colorado through the acquisitions of KLCX(FM) and KWRY(FM), serving the Pueblo market and surrounding regions.

The acquisitions happened at different times, but both stations have long been combined into a common antenna. That antenna originally was designed to accommodate 104.9 and 107.9 MHz. KLCX broadcasts K-LOVE on 106.9 MHz, and KWRY carries the Air1 format on 104.9. Unfortunately, 106.9 MHz was not in the frequency range of the original design.

There were other concerns with the existing antenna, including its lack of protection against icing and other weather. The transmitter site is about 30 miles southwest of Pueblo in a mountainous area, so ice would often detune the antenna and raise VSWR levels, reducing coverage.

Following a severe system failure, we reached out to Dielectric for help, which led to the purchase and installation of a Dielectric DCR-M antenna and two-station combiner. In the months since installation of the antenna, combiner and two new transmitters, the new RF systems have eliminated all existing problems while strengthening our signal coverage.

The DCR-M model is a center-fed, eight-bay antenna with an omnidirectional pattern. The antenna design has unique attributes to meet the weight and wind load limitations of our tower. A typical two-station antenna uses half-wavelength bay spacing, which would have required 16 bays to produce the appropriate antenna gain and 100 kW ERP with a 30 kW transmitter. The 16-bay antenna loading would not have been a solution for the current tower without significant tower modifications.

Dielectric solved this problem by spacing the antenna bays at an approximate 0.92 wavelength, which allows the 100 kW ERP to be produced with a lighter eight-bay design.

Dielectric’s “funky elbow” design maintains the full-wavelength electrical spacing between the antenna bays while allowing the physical spacing to be reduced, resulting in near full-wavelength bay spacing antenna gain. It also simultaneously reduces the RF radiation on the ground, which was a concern given the tower’s proximity to walking trails, campsites and wildlife.

The antenna also includes a “fine matcher,” which allowed for easy adjustments of the antenna system’s input impedance upon installation on the tower.

Galvanized Endeavors of Colorado Springs handled the DCR-M installation, as well as removal of the old antenna and damaged transmission line. The new antenna mount and transmission line were put into place, and the antenna was installed on the tower with its center of radiation positioned at 163 feet above ground level.

Given that the site elevation is at 8,350 feet above sea level, the antenna is prone to very heavy winds (often above 100 mph) and a consistent 20-to-30-inch snowpack in the colder months.

These weather conditions truly require antenna protection, and Dielectric’s antenna radome design has already delivered. We experienced a hefty snowstorm in October, which left several inches of ice and snow on all surrounding structures. The antenna was white from top to bottom, yet the radomes offered full protection from the wintry conditions. The antenna remained in tune, and with no change to VWSR levels, which remained steady between 1:05 and 1:08 across both station frequencies.

Inside the transmitter building, the Dielectric two-station combiner is properly matched to both the transmission frequencies and the transmitter power output. This means the combined signals are sent to the antenna with the right amount of power with minimal loss and a proper safety margin — all while meeting the mask requirements. The combiner properly prevents intermodulation issues from the two signals mixing along the path.

Even though the transmitter site’s mountain elevation required the RF components to be derated for altitude, Dielectric’s modern combiner design is compact, and the new system opens up a great deal of interior building space.

As this is a shared space, floor space is at a premium. The new combiner fits comfortably in the building, which allows us to make the most efficient rigid transmission line run possible — a perfect convergence point with the antenna feedline coming into the building. The location of the combiner means I can access the rear of my transmitters and audio racks comfortably to perform maintenance.

Two months in, the new Dielectric system has exceeded our expectations performance-wise, while providing a robust and reliable solution which has simplified our lives in engineering.

The Media Bureau, Video Division (Bureau) has before it a Notice of Proposed Rulemaking issued in response to a petition for rulemaking filed by Sander Operating Co. III LLC (Sander), licensee of KGW, channel 8, Portland, Oregon, requesting the substitution of channel 26 for channel 8 at Portland in the DTV Table of Allotments. The Bureau had instituted a freeze on the acceptance of rulemaking petitions by full power television stations requesting channel substitutions in May 2011 and waived the freeze to consider Sander's proposal to substitute channel 26 at Portland. TEGNA, Inc., filed comments in support of the petition reaffirming its commitment to applying for channel 26. The Bureau believes the public interest would be served by the substitution and will permit the station to better serve its viewers, who have experienced reception problems with VHF channel 8.

Look closely. A cleaning product has damaged this after-market shockmount.

Allowing employees to work from home is an excellent way to keep them safe and healthy in a pandemic, but it’s not always possible. So keeping radio studios clean is more important than ever.

Best practice, of course, starts with training staff in proper hand washing and the use of hand sanitizers. And hopefully you have issued individual microphone windscreens to your air talent.

But what about cleaning your specialized radio equipment?

Let’s share some recommendations from manufacturers. The information should not be taken as a final say but as supplemental to national guidelines and what organizations like the Center for Disease Control and World Health Organization recommend.

Knobs become globs

The components of popular cleaning products can cause unexpected problems when used on broadcast equipment.

Jim Gray of Optimized Media Group has a client whose staff started bringing in household cleaners when the pandemic struck. These included 409, Clorox, Windex, Lysol and a few other familiar brands.

But many such cleaners contain ammonia, which can be very harmful to rubbers and plastics. Whether from one particular cleaner or a combination of them, the gear at the station reacted badly. Equipment knobs became soft and deformed. Automation screens became cloudy. Mic shock mounts had to be replaced.

Rubber-coated keycaps can turn to “jelly” after frequent cleaning with non-approved cleaners, such as products with ammonia.

Jim estimated the cost of the damage at around $2,000. Since making the necessary repairs, he has purchased disinfectants that are electronics-safe. He is using 70% isopropyl alcohol as his cleaner but encourages others to do their own research for their needs.

The CDC doesn’t have radio-specific guidelines, but for electronics it suggests using covers that can be wiped down when possible. Of course this is not practical for devices that are in constant use.

Follow manufacturer instructions for cleaning and disinfecting; if no guidance is available, use alcohol-based wipes or sprays containing at least 70% alcohol. Apply it to a clean cloth, not directly to the surface. Then dry the surfaces thoroughly.

For convenient cleaning, Jim Gray cut a roll of heavy paper towels in three and put them in a disposable Rubbermaid food container with 70% isopropyl alcohol.

The CDC has a detailed information page about disinfecting facilities, including sections on soft surfaces, electronics, laundry, outside areas and other problem spots.

Ask the makers

As the CDC points out, manufacturers are a key source of information on how to clean and disinfect specialty equipment.

For instance, at Telos Alliance, Support Engineer Johnny Goldsmith and Marketing Coordinator Bryan Shay note that some parts on Axia products have rubber coatings, so home cleaners may cause problems.

They recommend 70% isopropyl alcohol applied with a dampened soft cloth; allow it to sit on the equipment for 30 second or more, then thoroughly dry with another soft cloth.

Telos Alliance reminds us to wipe with 70% alcohol solution, let sit, then dry.

They say you should avoid using Clorox brand or similar wipes on consoles and similar equipment because it may cause fading of printing. They advise against spraying disinfectant or cleaner directly on a surface, because liquid can cause great problems if it penetrates the electronics.

On Telos VSet phones, the handset may be cleaned with Clorox wipes, but the company still suggests isopropyl alcohol, to be sure to not get liquid into the earpiece or mouthpiece holes.

Goldsmith says check out the company page “Recommendations for Cleaning and Sanitizing Consoles and Equipment.”

At Wheatstone, Support Technician Dick Webb says look for disinfectant wipes that are labeled specifically as suitable for use on electronic devices. Check the ingredients and avoid anything corrosive.

Dick recommends you test a cleaning product on an inconspicuous area to make sure it doesn’t hurt the surface. Also, in addition to not spraying gear directly, he notes that a cloth can also cause damage if it is sopping wet, dripping liquid onto and into the electronics.

Mic care

Microphones are an obvious area of concern. Where windscreens are in use, each user should be issued their own.

For cleaning, Audio-Technica’s Audio Solutions department says you can remove a windscreen and spray it lightly with a disinfectant. Foam windscreen and headphone coverings can be washed by hand with mild soap in a sink, but carefully wring them out and dry thoroughly before using them.

For mics, arms, booms and headphones, dampen a wipe with 70% alcohol and wipe the surfaces. It should be wet enough to show moisture on the surface being cleaned, but never so much that it saturates the internal workings.

Most microphones have metal grilles as well as foam or other material to cut wind/pop noise. The grilles can allow bits of food as well as viruses and other germs to get in. Some manufacturers suggest spraying a mic very lightly with a “mist,” but Audio-Technica specifically advises against that.

“If a microphone has a removable metal grille, as most handheld microphones do, unscrew the grille and clean it while it is separated from the diaphragm and electronics of the microphone,” it states on a support page. “Internal windscreens should likewise be removed from the grille and cleaned separately.”

Though cleaners with ammonia or chlorine may be effective for viruses, I’d be very concerned about their use on microphones as both can destroy soft materials quickly; and they can leave a pretty foul smell for someone putting their face a few inches from a mic.

For a useful and detailed discussion, see “How Do I Clean My Audio-Technica Microphones?” For other brands, try a similar search or consult the manufacturer.

The folks at ElectroVoice add that if the mic has a removable threaded-on grille, it can be removed and soaked with the inner foam components in hot soapy water. The grille and foam components should air-dry before you put them back together and use the mic. For fixed grilles, a clean, soft-bristle toothbrush can be used to clean between the strands of grille wire. Visit https://electrovoice.com/support/troubleshooting/.

Cabinetry

Of course, regularly clean surfaces that people touch a lot such as light switches and doorknobs. Cleaners like Brillianize, used with microfiber cloths, can kill 99% of bacteria, according to a study from University of California, Davis, which the company notes on its website.

Studio furniture is one such surface. David Holland, chief design officer of Omnirax, says the company builds its countertops using Wilsonart high-pressure laminate, a very durable material. On these you can use more robust cleaners than with electronics.

Omnirax builds products with durable Wilsonart HPL. It suggests getting in the habit of trying any cleaner in an inconspicuous area first.

Wilsonart suggests cleaning first with dish soap, warm water and a soft cloth, then apply a SARS-CoV-2 approved disinfectant. In the absence of that, use a diluted bleach solution based on CDC guidelines (remember to test the cleaner first on an inconspicuous area):

Wilsonart has a helpful nine-page guide that includes discussion of specific brands; find it at https://tinyurl.com/rw-wilsonart.

You never want to forget your remote gear. Not only is it in contact with people, it’s also out in the field.

Jacob Daniluck of Tieline echoes the advice to never spray directly onto your gear and to use a clean soft rag dampened with 70% isopropyl alcohol.

Tieline and other manufacturers say don’t spray your gear; instead use a cloth that is dampened but not sopping wet. A solution of 70% isopropyl alcohol can be used.

A final note is that OSHA requires businesses to keep Material Safety Data Sheets (MSDS) for all chemicals and cleaners; keep this in mind when dealing with chemicals at your station. Should someone be “spritzed” in the eyes or inhale a cleaner, you’ll need to know how to treat them. You should consult OSHA regulations and/or your safety managers.

To summarize, manufacturers want us to be smart and well informed about cleaning. The real experts are doctors and scientists, so the manufacturers I spoke with all said that you should refer to CDC guidelines when it comes to protecting the health of your employees.

While this pandemic will eventually be overcome, colds and flus will not. Maintaining our best cleaning practices will help minimize sick staff and downtime in the future and keep your equipment and studios safe.
