The Federal Communications Commission last week finalized the dates for its planned NCE FM new station application filing window.

The Media Bureau announced that the window will be open Nov. 2 to Nov. 9, 2021.

The opportunity is just for 88.1 to 91.9 MHz, which is the FM reserved band (Channels 201 to 220).

“New applications must be filed electronically on FCC Form 2100, Schedule 340 in the Bureau’s
Licensing Management System (LMS),” it stated. “The commission recently amended its rules and procedures for filing NCE FM applications and selecting and licensing competing NCE FM applications.”

As we’ve reported, any given entity is limited to filing 10 applications.

Details about filing procedures and requirements will be in a subsequent public notice and posted on the Audio Division Web Page when published.

The Society of Broadcast Engineers has issued helpful guidance to stations about what to do in light of the failure of an IPAWS Required Weekly Test on Monday.

“When FEMA issues an IPAWS test or alert it includes a “‘certificate,’ SBE explained in an email to members.

“This operates similar to a password for accessing different sites or files on a computer. In the case of a message from FEMA, a message without a correct signature, the EAS device should ignore the message.”

SBE reported that on Monday, April 26, the Required Weekly Test from IPAWS was transmitted with an incorrect signature.

“The test messages had a mismatch between the digest inside the message, and the digest computed by receivers. This is a part of the validation for an alert, and checking it is required by FCC Rule 11.56(c): ‘EAS Participants shall configure their systems to reject all CAP-formatted EAS messages that include an invalid digital signature.’”

[Read: FCC Will Explore EAS on the Internet]

SBE emphasized that all EAS devices should have rejected the test including units made by Sage Alerting Systems, Digital Alert Systems and Trilithic. The advisory describes how various models should have responded and what you should do next; read that here.

It also said all EAS units would have reported failed validations in a temporary log, and that users should check with their device manufacturer for the location of that file and the correct “signature validation” settings for the unit.

“Stations should check and correct any issues before the next test on May 3, 2021. Stations should insert a note in the station log indicating the failed test and the reason for failure.”

Part of the Shulins Solutions Stellar Eclipse broadcast site monitoring and protection system installed in Houston.

A familiar name to Radio World readers Paul Shulins is the subject of our latest Who’s Buying What news.

His Shulins Solutions, a provider in select engineering services and broadcast consulting, recently installed its Stellar Eclipse monitoring system at a shared combiner and antenna facility serving four Houston stations.

[See Our Who’s Buying What Page]

Shulins Solutions offered this description of the system: “Stellar Eclipse with our exclusive VSWR Sentinel is designed to protect and monitor these systems by constantly monitoring the VSWR on all inputs and outputs to the combiner system, refreshing these values many times every second. Anytime a VSWR is detected that exceeds a preset threshold, hard relay interlock relays are controlled that can open interlocks on connected transmitters. RF power is then removed from the system when an unsafe condition exists, thereby saving the systems from costly damage.”

It added that it, “provides unique cloud-based monitoring of many shared systems often overlooked in an individual stations remote control.”

Amador Bustos is president and CEO of Bustos Media, owner of radio stations in Arizona, California, Texas, Washington state and Wisconsin. The stations mostly broadcast in Spanish but some offer English-, Chinese-, Korean-, Russian- and Vietnamese-language programming. He discusses the state of radio broadcasting and Bustos Media stations.

He was interviewed by Suzanne Gougherty, director of MMTC Media and Telecom Brokers at the Multicultural Media, Telecom and Internet Council. MMTC commentaries appear regularly in Radio World, which welcomes other points of view on industry issues.

Suzanne Gougherty: For more than a year the thirst for information regarding the pandemic has been at the forefront of news — how have your radio stations kept your audience informed on current news and information?
Amador Bustos: Since we are primarily a music intensive station group, and our DJs were working from home, they had to rely on news feed from our local newspapers and television stations. Besides our AM-drive top-of-the hour newscast, we expanded our pandemic coverage to live commentary and interviews with local health officials at any time of the day.

[Read: Keeping Sports Hot in the Age of Coronavirus]

Gougherty: What do you think is the most overwhelming challenge of the radio industry today, and where do you see the best opportunity for growth?
Bustos: The most pressing challenge for radio is the false assertion by social media outlets and digital audio competitors who are continuously forecasting the death of terrestrial radio. The best opportunity for revenue growth is in entertainment and event production. Due to the year-long isolation there is a strong pent-up demand for indoor concerts and outdoor festivals.

Gougherty: As a successful entrepreneur what was the motivating factor that led you to owning and operating radio stations?
Bustos: The opportunity to generate wealth. When I started buying radio stations the revenue margins were much higher. Secondly, to increase ownership diversity. I saw a rapidly expanding number of radio stations targeting the Hispanic market, but too few of us were represented in the ownership ranks. That continues to be true today.

Gougherty: It was reported that full power radio stations, plummeted at the end of 2020, on both the AM and FM dials. Do you feel the industry will experience the same decline in 2021? Do you think there is a solution other than to turn licenses back to the FCC?
Bustos: Yes! Radio revenues plummeted during the second and third quarter of 2020. However, the recovery during the last six months is encouraging. It is important that we make the distinction between AMs and FMs. Our AMs continue depressed. This year, I will likely return more than one AM license to the FCC for lack of sustainable revenue.

Gougherty: Should the FCC relax or retain the local AM and FM ownership caps and subcaps?
Bustos: The FCC should relax the ownership caps and subcaps. However, it should do it in two or three stages. First in markets above 100, then in markets above 50 and finally in all markets. At each stage the FCC should look at the unintended consequences of excessive concentration, negative impact on AM values, diminution of public service and ownership diversity trends.

Gougherty: What steps should Congress and the FCC take now to dramatically increase minority radio and television station ownership?
Bustos: Congress and the federal government can do two important things: 1) Reinstate the Minority Tax Certificate; which gives sellers a tax deferral if they sell to qualified diverse buyers; 2) Allow the SBA to do bank loan guarantees of up to $10,000,000 for the purchase of broadcast properties by qualified diverse borrowers/operators.

Gougherty: Spanish-language radio stations’ music formats have done well over the years. Do you feel there is room for other Spanish-language formats, talk, sports or news?
Bustos: There is room for those additional formats. However, they are more expensive to produce. That is why several past attempts have failed. It will take a well-capitalized and committed broadcaster to support such an effort. Just like iHeartMedia has done when it launched the Black Information Network in June 2020.

Gougherty:. During the recent roll-out of vaccines what kind of factual information have your stations provided to your listeners? And do you feel it has help to dispel the myths or misinformation that might be circulating in the Hispanic community?
Bustos: We have provided our audience information based on CDC’s guidance, as well as information provided by state and local health officials. Most of our on-air personalities are pro-vaccination and regularly speak in favor of it. When they are vaccinated, they disclose it and recommended it.

Gougherty: How has your sales team held up during the past year? And your on-air talent? Are all working from home or with strict measure at the work place? And as the owner how are you holding up?
Bustos: There is a clear sense of fatigue. Most employees are desirous of a return to the office. If things continue to trend well, we will likely have most employees return to an interactive, in-office work by June 2021.

 

The post Looking to Radio for a Bounce-Back appeared first on Radio World.

Remote control systems have come a long way in my 45-year broadcast engineering career. I have had the pleasure — and sometimes frustration — of following these changes.

There was a time when you could call the phone company and order a “dry pair” from point to point, and over that dry pair you could connect your remote control system with its telephone dial, stepper relays and DC metering.

Those old systems were always interesting, especially when the steppers got out of sync, but somehow they got the job done.

Then came the Moseley TRC-15 types that used audio tones for telemetry. We could use those over a dry pair or just about any bidirectional telco circuit, or you could use them over a subcarrier on an STL for the outbound control functions (if I recall correctly, this used a 300-400 Hz FSK scheme for the wireline version).

Some folks used an over-the-air SCA for telemetry backhaul for the TRC-15 — if you couldn’t get a reading on anything, the transmitter must be off! — but others used telemetry return links on one of eight discrete 450/455 MHz frequencies designated for such by the FCC. And there were no status indications.

But all in all, the TRC-15 was a huge step up (no pun intended) from the old stepper relay DC remote control systems. It was an even better platform if you installed the digital telemetry adaptor offered as an aftermarket add-on from Hallikainen and Friends.

Up in smoke

There were some digital systems from Moseley that came after the TRC-15. I remember using them in some of the TV stations at which I worked. The red LED digital readouts took away the sometimes difficult task of meter scale interpretation and interpolation, always a plus with busy master control operators!

Then in the early 1980s came the MRC-1600, a 16-channel digital remote control with status. I thought I’d gone to heaven when that unit came out … until the first lightning strike.

The old TRC-15 didn’t seem to care much about lightning, but that MRC would go up in smoke every time the sky got cloudy, or so it seemed. I remember that the display would say OUCH! if an input channel got hit with too much voltage or if one of the multiplexers was damaged.

That sensitivity to static discharges bit me one time, too. It was always a challenge to remember to take the R/C out of “local” and put it back in remote when leaving a transmitter site. One TV station at which I worked had a red 60-watt light bulb in a porcelain socket right next to the door, and that bulb would be lit whenever the remote control system was in “local.” That saved a lot of midnight trips back to the tower site.

I wanted something similar at one radio site I took care of, so I thought I would put the NC contacts of the local/remote relay in series with the alarm system door contact — it would then be impossible to set the alarm with the remote control in the “local” mode.

That worked great for about a day, until the next thunderstorm. The MRC lost its mind (OUCH!) and opened that local/remote relay and set off the burglar alarm.

It was a long drive from my house to that tower site at “Cadaver Creek” in stormy weather with the alarm wailing and the police on the way.

Talking control

In the late 1980s, Gentner Engineering came out with the VRC-1000, a revolutionary new “talking” remote control system that worked over a dial-up phone line.

That changed everything for radio stations. No longer would they need an expensive dedicated line or dry pair for remote control, or a fussy, interference-prone telemetry return link that would blank out whenever a cab driver passed by the studio while talking on his dispatch radio.

A Gentner VRC-1000 “talker” is visible in the right rack bay. When that model came out, we thought we’d gone to radio heaven.

The early vocabulary was limited, but we made it work. And the best part was that the unit would call us when something went wrong. Programming was a chore, but it was just so … cool … that we didn’t care!

Later iterations of the Gentner VRC (and Burk GSC) had improved vocabulary and other capabilities, and some of these units are still in service today.

If memory serves, Gentner came out with a “sample and hold” system to interface its VRC-series systems to analog antenna monitors, and that worked pretty well except right after pattern change — you had to wait for the next sample to get an accurate set of readings.

Potomac Instruments came out with a pretty good and capable system in the late 1980s. Interfacing remote control systems to analog antenna monitors was always a difficult task, and the Potomac RC16+ had a means of doing that, using a scan function to constantly monitor operating parameters.

The thing that probably kept the unit from greater popularity was that it could not be programmed in the field — it was EPROM programmable, and that had to be done by the factory. Need to make a change? Fill out this form and we’ll burn and ship you a new EPROM.

That worked, but it was anything but convenient, and it certainly discouraged programming changes. Still, it was a rugged, reliable system.

IP all the way

The name Burk became synonymous with “remote control” in the mid-1990s, and that remains the case today.

The first Burk systems I used were ARC-16s, and they were good, rugged, reliable units that could be configured as stand-alone dial-up, dedicated studio/transmitter pairs of a combination.

These systems had RS232 capability, and you could purchase an IP-to-RS232 adaptor to link your units together over a network or even the internet. Multiple sites could be linked, a popular feature in the age of consolidation. There are a lot of ARC-16 systems still out there in service, and for good reason.

Which brings us to today and the ARC Plus and ARC Plus Touch systems, which are nothing short of amazing. These units use IP connectivity all the way, and the ARC Plus Touch has SNMP and API capability.

This IP-based remote control is not the latest-greatest model from Burk but remains very capable.

In our company, the last few transmitter installations we have done where we had a Touch system in place did not use so much as an “RF On/Off” wire connecting transmitter to remote control — everything was done by SNMP. Which I should say can be a bit like drinking from a fire hose with some equipment interfaces — there are so many parameters available to monitor.

I should not fail to mention systems by Sine Systems, Broadcast Tools and others that provide a bridge between technologies and an excellent means for stations with limited resources to avail themselves of many of the features of much more expensive systems. I have used some of these systems in niche applications even within larger operations and found them very useful.

Today’s remote control systems, along with companion software, can do a lot of things. Many can run scripts and macros that can make decisions. You can make the logic as simple or complex as you wish using IF/THEN statements and AND/OR Boolean operators. Actions can be scheduled based on a calendar/clock, or they can be triggered by some external input or event, even taking input from external off-site data over the internet. They can blow up our phones or drive us nuts with texts and emails. I love the mobile web page displays of some remote controls, where I program things green-good/red-bad. A busy operator or engineer can tell at a glance if all is well.

One of the best macros that one of our engineers uses sends a text to her phone every 10 minutes whenever the remote control system is in the “maintenance” mode (the modern version of the “local” mode). That ensures that she won’t get more than 10 minutes down the road before she realizes she forgot to turn that off before leaving.

Not once since implementing this macro has she had to make an emergency run to a site at pattern change time when the pattern couldn’t change because the command relays were disabled! And not once has this set off the burglar alarm at a site!

In this day and age of ultra-capable remote control systems, our transmitter sites can be almost completely autonomous, which translates to fewer of the time pressures that often accompany equipment malfunctions. Such a remote control system can react to the failure, look at multiple variables and make decisions that will get the station back operating again in less time that it would take the engineer to answer his or her phone. That’s worth something.

Line pressure

Every AM, FM or TV transmitter must be connected to an antenna via some type of cable, normally a coax line. Some lines are constructed with a type of foam between the inner conductor and the outer conductor, while others are hollow.

If your system has the hollow type of transmission line, it is imperative that some type of gas pressure be inside the line. Transmission lines can be vulnerable to corrosion if they are exposed to oxygen and moisture, the two main components that cause a corrosive reaction.

Properly pressurizing coaxial cables will keep moisture out and therefore prevents arcs inside the cable and it improves the power-handling capacity of the coax by increasing the breakdown voltage between the inner conductor and the shield.

Engineers often ask which is more effective, nitrogen or using a dehydrator. The answer is, “It depends.”

If you will be operating the transmission line at or near the power rating of the line, nitrogen will give more protection from arc over. For lower power levels, either will work.

A properly sized dehydrator will keep your lines dry and pressurized. Some, like this model from Kintronic Labs, have web interfaces to allow monitoring of pressures.

To keep moisture out, the transmission line must be kept at a positive pressure relative to the outside pressure. The pressure required is minimal indeed; maintaining excessive pressure can damage the line and waste energy.

When it comes to dehydrators, proper sizing is everything. If undersized, the unit must run longer in order to maintain pressure, increasing wear on the compressor and driving maintenance costs higher. An oversized dehydrator, however, creates pressure surges in the line. This causes the unit to constantly cycle on and off, again resulting in increased compressor wear and higher maintenance costs.

It doesn’t take much pressure; 3 or 4 psi is more than adequate to keep moisture out of the line and antenna.

The most important takeaway point is to have a method to monitor the pressure in the line and an alarm system to notify engineering of a sudden loss of pressure on the line. This could be caused by failure of the dehydrator or empty nitrogen supply. It could also indicate a pending failure in the line itself caused by a major gas leak created by lightning or even a bullet hole.

When installing a new line, it is advisable first to pull a vacuum on the line. This will remove all the moisture from the line. Then fill the line with nitrogen or dry air from a dehydrator. Do not use a standard air compressor for this purpose, since it will fill the line with normal air, which is full of moisture.

This type of failure will be extremely costly and time-consuming. Don’t neglect this important part of your transmission system!

Noncommercial radio is about to see the biggest boom in years. The Federal Communications Commission announced the dates when it will accept applications for full-power noncommercial radio stations later this year.

The announcement is massive news for noncommercial broadcasting. The FCC is making license opportunities available nationwide for the first time since 2010. Following criticism of that 2010 window, the commission has placed limits this time on the number of applications one can make. With a cap of 10 filings per applicant this time, the playing field is as wide as it will be in more than a decade.

A bigger 2007 window saw more than 1,300 construction permits approved. It is hard to say how many we’ll see when the 2021 application window opens Nov. 2–9.

[Read: Community Broadcaster: Hidden Figures]

Why does the new FCC application period matter? Noncommercial broadcasting has exploded in the last 20 years, more than doubling in number as AM and commercial FM are seeing declines. Every class of 501(c)(3) nonprofit organization and beyond is looking at Nov. 2–9 with high expectations. For publishers and community media, radio represents a foothold in legacy media that still counts a great deal. For faith-based organizations, radio means connecting with followers. For nonprofits with little previous relationship with media, radio can be a chance to reimagine their missions. And for the communities where stations may be approved, you’re talking about new possibilities for radio’s growth.

If you are interested in being one of those filers later this year, there are many items of interest.

Among the top priorities for filers is the application itself. FCC Form 340 is a very detailed document requiring applicants to present a broad range of technical, infrastructure and public disclosures as a part of the process. From producing proof that your nonprofit organization has the operating capital to run a station; to governance records; to engineering plans for your signal, antenna and more, filing your application will be a time-consuming process. You will want to review the application, select appropriate consultation, and act early to get it done.

You and your engineer will need to do the bulk of the work. It is on the aspiring broadcaster to propose a space that meets at least the minimum requirements and prove you are not stepping on others’ signals. This can be a complicated set of mathematics upon which you will work closely with your engineer.

Larger nonprofits interested in becoming broadcasters may want to get familiar with newer rules or consider retaining an attorney. In 2019, the commission took steps to streamline the application process, but still there are particular requirements of note. These revisions include declarations around governing documents of certain applicants as well as divestiture commitments.

The National Federation of Community Broadcasters last year hosted a primer on the full-power application window opening in November. There will be an updated discussion in July at the Wish You Were Here conference.

Dennis Sloatman, left, visits with John Bisset at a trade show.

Dennis Sloatman recently retired from his position as vice president of engineering at SummitMedia. “After 51 years as a radio broadcaster, I’m finally getting out of the way for the next generation,” he wrote on social media.

“Now more time for mountain biking, hiking and messing with my control system projects. Overall, it’s been a good career.”

I took the opportunity to catch up with him about his career.

Paul McLane: How did you get started in radio tech?

Dennis Sloatman: I was a “broadcast radio nerd” growing up in Rockford, Ill., while listening to WCFL and WLS in Chicago, with the vainglorious hope that I could one day be a bigtime Chicago DJ like Larry Lujack and the “World Famous Tom Murphy.”

McLane: Tell us about your career path.

Sloatman: I began my career working at various stations in Northern Illinois: WRVI, WKWL, WRWC and WRRR as a DJ and unofficial “technical helper.” Then on to KHAK in Cedar Rapids, Iowa, as an overnight DJ and ultimately, chief engineer, in 1977.

WDLS (for “Dennis L. Sloatman”) was a Part 15 100 mW AM station in Rockford, Ill., when Sloatman was a teen. Studios were in his basement.

Then I worked for Harris Corp. as a field service engineer in Quincy, IL.

Beginning in 1980, I worked for WORL, WMGF, WOMX, WLOQ, WMFE, WDBO, WMMO, WOCL and some others as chief engineer spanning 28 years, from 1980 to 2008, in Orlando, Fla.

Then I was chief engineer of the Cox four-station cluster in Richmond, Va., from 2008 to 2012.

While in Orlando, I taught electronics mathematics, electronic communications, electronic circuit analysis, A+ Hardware and A+ Software at Valencia College and University of Central Florida.

In 2012, I accepted a position as VP of engineering for the 10-station iHeartMedia cluster in Los Angeles, including famous stations such as KIIS, KFI and KBIG.

And then in 2016, for quality of life reasons I chose to move back to Richmond, Va., as VP of engineering for Summit Media where I  ended my career after 51 years in 2021.

At work for Harris.

McLane: Who were your mentors?

Sloatman: Early in my career in Cedar Rapids, my first CE job, my mentor was Robert F Burns — that’s right, “RF Burns!” I’d also have to recognize Larry Caldwell, chief of WRRR Rockford when I worked as his assistant engineer in 1975.

McLane: What are your feelings on stepping away from full-time engineering?

Sloatman: Relaxing! No longer on 24/7 call after 50+ years “being available at a moment’s notice.” I do miss daily solving problems and designing solutions, but I plan to direct those energies at other projects.

McLane: Looking over your major projects and accomplishments, is there one that stands out?

Sloatman: Well, one might expect I’ve built a great many studios, transmitter sites and broadcast facilities in Rockford, Cedar Rapids, Orlando, Michigan, Richmond and Los Angeles.

Clean room: Transmitters at SummitMedia station WKHK(FM) in Virginia.

All in all, I feel as if my part in turning the Los Angeles facility around and bringing modern technology and methods to the market was a highlight. In a similar manner, bringing professionalism and dignity to engineering management with SummitMedia is something I am proud of.

McLane: Would you encourage a young person to go into this field now?

Sloatman: First, I must say that I love the radio broadcasting business and being a lifelong problem-solver as a broadcast engineer. The exposure to almost every form of technology is exciting and challenging.

On the more negative side, I have to say I have always had a problem for what I perceive as a lack of appreciation by some managers for the vast knowledge and experience required of the modern broadcast engineer — electronics, RF, audio, FCC rules, control systems, computer and network technology, etc.

This lack of appreciation is made manifest by requests to the CE for handyman tasks such as changing lightbulbs, plumbing, hanging pictures, vehicle maintenance, etc.

I fully recognize that many of my brother engineers have no problem with this aspect, but I feel I didn’t devote my career and my engineering degree to be a handyman or anything less than a professional.

Therefore, yes, I would encourage young people to give it a good, hard look; but also I would make certain they are aware of what I perceive as the less attractive aspects of the job.

Now, this experience will vary depending upon the company and its management. Research is required before accepting a position. Some broadcast companies treat their engineers with respect while others act as if the engineer is chattel.

It’s difficult at best these days to find that one “right” person for the job, and I feel the industry sort of “shoots themselves in the foot.”

McLane: What else should we know?

Sloatman: I’d have to say the most enjoyable and rewarding part of my career came in the final decade when I managed a staff of 10 fantastic people in the IT and Engineering department in Los Angeles and later, the market engineers of SummitMedia. All great people and I will miss working with them.

Sloatman also joked on LinkedIn about his sense of relief: “No longer am I more nervous than a long-tailed cat in a room full o’ rockin’ chairs!”

Anyone who has installed and upgraded IP infrastructures in the broadcast plant knows that racking up and cabling equipment is the easy part of the job. The more tedious and time-consuming aspect is usually the administrative tasks that follow: initial setup and registration, device management and security. Proprietary and piecemeal tools exist, but locating end-to-end solutions can be elusive.

Lawo Home is new a cloud-based management platform for IP-based infrastructures. With it, according to the company, users can perform automatic plug-and-play discovery of IP audio and video devices. They are registered with their name, location, status and type. This applies not only to Lawo products but to third-party devices as well, using NMOS. Discovered devices are managed in a central inventory list, ready for access and configuration.

Nothing changes but the changes in a media IP infrastructure, and the ability to save and recall multiple configurations is key to speeding up tasks. Home, according to Lawo, provides a centralized “mission control” for these processes, providing fast and unified access to device parameters for easy tweaking, irrespective of the end point being controlled.

The content flowing around the infrastructure is a media organization’s most valuable asset. Part of  any IP administration solution’s job is security, not only for those assets, but also for the infrastructure. And doing this job seamlessly in the background is key.

Lawo claims that Home makes a variety of strategies available. First and foremost is quarantining unknown devices when they come online. Only after being approved via an intuitive IEEE802.1X-based routine, can they begin exchanging signals with the Home network.

A second approach is an authentication strategy based on a centralized user management system, with dedicated user roles and groups. The LDAP-based service allows users to authenticate either locally — within HOME — or via their own corporate IT infrastructure, e.g. Microsoft Active Directory, according to Lawo.

Finally comes the arbitration of devices and individual streams based on pinpointed rights management. Home’s architecture, says Lawo, is prepared to manage services such as transport layer security, network segmentation and other IT security mechanisms such as Radius.

The FCC is diving into wireless multichannel audio systems (WMAS), an emerging wireless microphone technology designed to enable more microphones per megahertz of spectrum.

The commission has officially adopted a Notice of Proposed Rulemaking that is seeking public comment on whether WMAS technology should be granted a licensed basis in frequency bands where wireless mics are already authorized. This includes TV bands, the 600 MHz duplex gap and in portions of the 900 MHz, 1.4 GHz and 7 GHz bands. The NPRM also looks at using WMAS on an unlicensed basis.

WMAS allows microphones to operate using wider bandwidth channels than FCC rules currently allow by digitally combining multiple mic signals. It also uses a more efficient operating protocol, resulting in a larger number of wireless mics being able to operate in the available spectrum.

Europe has already permitted the use of WMAS technology under the European Telecommunications Standards Institute standards.

The proposals are designed to amend the FCC’s Part 74 licensed radio device rules — known as low-power auxiliary station (LPAS) devices — to support efficient use of spectrum and implement interference protection standards. The proposal also seeks comment on whether the commission should permit WMAS to operate on an unlicensed basis under the FCC’s Part 15 rule.

Any changes are not intended to impact incumbent spectrum operations, the FCC claims.

“These [WMAS] systems have the potential to significantly improve the efficiency of wireless microphone operations,” said FCC Acting Chairwoman Jessica Rosenworcel. “So much so, that under the rules we propose here, three times as many microphones may be able to operate while putting the same amount of power over the air as a single wireless microphone does under our rules today.”

The NPRM was approved unanimously by the FCC during its April Open Commission Meeting.

When the Federal Communications Commission opens its filing window for new noncom educational stations in the lower part of the FM band later this year, it will limit the number of applications per party to 10.

The commission approved the limit on Thursday, as it was expected to do based on recent statements.

[Read: FM NCE Filing Window Coming in 2021]

 It said the general idea of a cap drew support in filed comments, though opinions varied on the number.

National Public Radio endorsed the 10-application cap. REC Networks and Common Frequency pushed for five. Educational Media Foundation thought parties should be able to file more than 10 applications if the additional ones were for areas outside the home counties of Nielsen Audio markets.

“We find a 10-application cap will best deter speculative filings, permit the expeditious processing of the applications filed in the window, and provide interested parties with a meaningful opportunity to file for and obtain new NCE FM station licenses,” the commission stated.

“We agree with NPR that the alternative REC and EMF proposals ‘fail to offer a demonstrably better balancing of the relevant objectives.’”

The commission wanted to cap the number of applications to avoid a repeat of the 2003 translator window in which it was swamped with 13,000 applications, many from speculative filers.

It expects a lot of interest in this window for several reasons: There’s no application filing fee; there are no ownership limits in the reserved band; there has not been a filing window for new NCE FM applications for over a decade; and the FCC recently simplified procedures including how it treats competing applications.

Canare microphone cable

Canare USA, a supplier of cables and connectors, said it is experiencing “experiencing extremely unprecedented long lead times, due to a shortage of ocean containers globally.”

In an email to customers and business partners, the manufacturer wrote, “We were once able to absorb costs for special air shipments; however, the prices have soared beyond expectations and we are no longer in a position to absorb 100% of the cost.”

By way of explanation it pointed to online news stories about “chaos” in global shipping including a shortage of ocean containers.

“As we navigate through these delays, we ask that you would be both understanding and patient with us, as we use our best strategies to bring you your much needed supply of Canare products.”

It encouraged customers to raise awareness of the state of the shipping industry, ask about emergency air shipments and to consider blanket orders to help assure availability.

Canare Corporation of America is based in New Jersey. Its parent corporation was founded in 1970 in Japan, where it is headquartered. The company name comes from a river near the founder’s office.

The Federal Communications Commission has established new sponsorship ID requirements. They require U.S. radio and TV stations to disclose when foreign governments lease air time.

All four commissioners voted to approve.

“The order increases transparency, ensuring audiences are aware when a foreign government, or its representatives, uses the airwaves to persuade the American public,” the commission said in its announcement.

Now, when a broadcaster leases time, they will need to ask the “lessee” if they or their programming are from a foreign governmental entity.

“If the answer is yes, a sponsorship identification will need to be placed on air and documented in the station’s public file,” said Acting Chairwoman Jessica Rosenworcel.

“If the answer is no, a broadcaster will need to independently verify the lessee using the Foreign Agent Registration Act website from the Department of Justice and the FCC’s semi-annual foreign media outlet reports.”

NAB opposition

The National Association of Broadcasters was against the move in this form.

NAB General Counsel Rick Kaplan blogged a few days ago that while the change is well-intended, it is too broad and would put a new substantial burden on broadcasters who enter into lease agreements with all program sources “to determine whether they are dealing with a foreign government in the first place.”

In his comments before the vote, Kaplan said “hundreds if not thousands” of stations would be “mandated to undertake steps to prove in advance they are not dealing with foreign governments, even when they each know with certainty they are not.”

He said there’s no evidence of a “groundswell of foreign propaganda” on the U.S. airwaves or that stations are confused about the origins of what they air. And he added that it’s unfair that broadcasters need to take such steps when foreign entities can communicate freely with Americans via social media.

Rosenworcel: “This is simple”

But the FCC believes that foreign governmental entities are increasingly purchasing time on domestic broadcast stations.

Rosenworcel said, “We know that foreign entities are purchasing time on broadcast stations in markets across the country, including Chinese government-sponsored programming and Russian government-sponsored programming right here in our nation’s capital.”

She said this is not only a recent phenomenon.

“During the last several years, press reports about the presence of this programming have multiplied. Moreover, Congresswoman Anna Eshoo wrote this agency eight times to demand that it do something to shed light on the use of our airwaves by foreign government actors. Today’s decision is a testament to her perseverance. It is also a statement about national security and the preservation of our democratic values.”

Specifically, the order requires disclosure for broadcast programming aired through a leased airtime agreement sponsored by any entity or individual that is a foreign government, a foreign political party, an agent acting on behalf of such entities, or a U.S.-based foreign media outlet based on definitions drawn from the Foreign Agents Registration Act of 1938 and the Communications Act of 1934.

The order also adopts a requirement that a station airing foreign government-provided programming pursuant to a lease agreement must include such disclosures in its Online Public Inspection File.

In a statement after the vote, NAB Senior Vice President of Communications Ann Marie Cumming emphasized that NAB “supports the FCC’s goal of ensuring that the public understands when it listens to or views programming supplied by foreign governmental entities” but wanted to avoid creating burdens “for the vast majority of broadcasters that do not air this content.”

“Even though we do not believe the commission ultimately achieved this aim, we greatly appreciate the efforts of Commissioners Carr and Simington to avoid undue regulatory burdens, and the efforts of the Media Bureau to constructively engage with us throughout this proceeding.”

Columbia Island today, on the market for $13 million. (Photo: Sotheby’s International Realty/Patti Anderson/VHT Studios)

This is the story of a station whose transmitter for two decades sat on an island — arguably the most famous such “island station,” WCBS 880.

The non-directional 50,000 watt powerhouse station, now owned by Audacy (the former Entercom), has been doing the demanding 24/7 format of news, sports and information for more than 50 years. At times it has been the nation’s most listened to station.

How did its transmitter end up on an island?

The saga of this flagship of the Columbia Broadcasting System started with the cigar business of Samuel Paley in the early 1920s. He owned a distribution company at a time when one of America’s growing male vices was a good cigar — or multiple cigars — a day. He dealt mainly with imports and focused on building brand recognition and brand loyalty to succeed in this emerging business.

Radio was “trending” at the time, the “new big thing.” Ad placement was the bailiwick of Sam’s son William Paley; they started using radio — ads and mentions — to get cigars into as many mouths as possible.

The power and the cost-effectiveness of radio piqued the younger Paley’s interest. Shortly thereafter the CBS epic began when he took over management of a nascent network of 16 stations, the Columbia Phonographic Broadcasting System.

In short order the Paley family and partners bought the operation. With 51 percent ownership, he ran and now controlled the network.

The file on WCBS starts with a different set of call letters. In 1924 the Atlantic Broadcasting Company applied for a New York station and got the apropos call of WABC. As with many stations of this period, WABC meandered around the dial until in 1932 it wound up on 860 kHz with 50 kW non-directional and a transmitter in Wayne, N.J.

The population of metropolitan New York was expanding along roads and transportation lanes into Brooklyn, via the famous bridge, and New Jersey, via the Holland Tunnel. Those demographic trends and travel corridors influenced the choice of new transmitter sites. Managers of other early stations serving New York City such as WOR and WEAF did likewise.

Central location

In 1936, CBS purchased the signal, adding to its station portfolio and distribution network.

In 1940 it sought to move the transmitter from New Jersey to what was then called Little Pea Island, located in lower Long Island Sound and northeast of Manhattan.

CBS bought the island and installed an aux transmitter for testing. The results demonstrated that the seawater conductivity would ensure formidable coverage in New York and New Jersey, and bonus extensive penetration into populous sections of Connecticut.

With the 1941 North American Regional Broadcasting Agreement, the station moved from 860 to 880 kHz shortly before the final move.

Little Pea Island — later renamed Columbia Island — is a modest tidal rock of about one acre in size. It became home to an extraordinary engineering installation featuring a 410-foot self-supporting top-loaded tower. In 1941 two underwater cables brought power from New Rochelle to the site, and operations began.

This image of the 410-foot self-supporting top-loaded tower appeared in a 1941 ad in Broadcasting magazine for Federal Telegraph transmission equipment. It was headlined “The New WABC: Key Station of the Columbia Broadcasting System.” The ad stated that the facility would deliver “performance characteristics unsurpassed by any similar installation in the history of broadcasting.” (Collection of John Schneider)

News accounts said CBS spent approximately $500,000 (the equivalent of about $9 million now) to construct the tower, transmitter with backup and the building, including emergency housing for 10 workers.

A headline in the New York Times in October 1941 read: “Radio ‘Island’ Comes to Life; WABC’s New Transmitter Is Called an Engineering Dream — Built on a Man-Made Rock in Long Island Sound.”

Daily boat runs brought a change of operating crew, food, potable water and other creature comforts from the “mainland.” Weather and waves were not always cooperative. The bedrooms, kitchen and other quarters were put to use by stranded crews when circumstances isolated the site.

Federal Radio, a division of IT&T, built the transmitter from its own advanced design. Few details for this rig are available but Federal used it as a model for CBS’s later shortwave station further out Long Island.

Evidently this earlier, similar 50 kW unit was plate modulated. The high voltage supply took three-phase power direct from the power company at 4600 volts using banks of mercury vapor rectifier tubes to make DC. Filaments were transformer-powered unlike earlier motor generator schemes.

Jim Weldon of border blaster fame worked on the Columbia Island station as a Federal Radio engineer.

The official starting date was Oct. 18, 1941, with Kate Smith and Orson Welles, personalities well connected with CBS, participating in the inauguration.

In 1946 the company received approval to change the station call letters from WABC to WCBS.

Up until the late 1950s transmitters were operated on site by engineers who were on duty whenever the station was on air.

The station had a tremendous signal penetration and was the very definition of a “clear-channel, Class A station” that reached well into the heartland of America. Further, the saltwater location provided possibly an even bigger reach throughout the Atlantic, making it the voice of New York City to many far away at sea in war and the following peace.

Like other similar important big stations including WTIC and WCCO, WCBS during World War II had a guard detail to protect the facility from sabotage or disruption.

One story, legendary but probably true, is that in thick fog, the crew once found its way to the island by following the induction field created by the currents flowing in the underwater power cable.

Moving on

Columbia Island provided a superb signal for CBS, but this rock was an expensive site to operate under any definition.

With the emergence of TV and the dropoff in network radio revenues, CBS explored locations nearby that were easier and more convenient to reach.

Eventually the corporate engineers settled on High Island just off the Bronx shore as a more practical site with a desirable land connection via a sandbar bridge.

After some delay and birthing pains, WCBS moved to that site in early 1962, where it remains today.

The station transmitter site was later moved to nearby High Island, shown. (Collection of John Schneider)

WNBC, 660, was diplexed into the tower shortly thereafter when crooner Perry Como decided he wanted the nearby site that NBC was developing for his New York City home! WNBC is now sister station WFAN 660. (It was this site that was knocked off the air by the fatal crash of a private airplane in 1967 on the day before WCBS launched its all-news format.)

Meanwhile, according to news accounts, Columbia Island was purchased by a show-business couple who aired a breakfast conversation show from their home there; then it went through multiple hands including the College of New Rochelle.

Actor Al Sutton eventually acquired it and built a “green” home on the site; you can find online stories about its construction, which is interesting in itself. At this writing, Zillow listed it for sale at $13 million. You can even take a video tour online.

But regrettably the 20-foot-square, 410-foot-high tower is long gone — regrettable, because for any resident the radio reception using that stick would have been extraordinary.

Broadcasting has often found some advantage or necessity to locate transmitter sites on islands. These islands vary from the isolated home of KUHB on frigid St. Paul Island in the  Bearing Sea to the defunct directional AM of WRIZ built on an island of pilings in Biscayne Bay in Florida.
