NAB, Others Say ‘Stay’ Again in Foreign Sponsorship ID Fight
On December 8, the FCC’s Media Bureau, led by Michelle Carey, issued an Order denying a stay petition filed by the NAB; Multicultural Media, Telecom and Internet Council (MMTC); and the National Association of Black Owned Broadcasters (NABOB) that sought to thwart a Commission order mandating disclosures for foreign government-sponsored programming.
Now, the groups are asking the D.C. Federal Appeals Court to grant a stay of the new rule.

Broadcasters Ask Court to Block Disclosure Mandate
Several prominent U.S. broadcast associations are asking a federal court to block an FCC order that mandates disclosures for foreign government-sponsored programming.
The request was filed Wednesday by the National Association of Broadcasters, the Multicultural Media, Telecom and Internet Council and the National Association of Black Owned Broadcasters with the U.S. Court of Appeals for the District of Columbia Circuit.
They previously filed a lawsuit with the court challenging the FCC order. They’ve argued that the commission lacks the authority to “impose the investigatory requirements mandated by the order,” lacked justification for the rules and failed to address problems with undisclosed foreign governmental programming on cable systems and the Internet, “which is where the issue primarily exists.” They call the action unnecessary and overly burdensome, and in violation of the Communications Act, the Administrative Procedure Act and the First Amendment.
[Related: “FCC Denies NAB Stay Petition on Foreign Sponsorship ID Rules”]
The FCC adopted amended foreign-sponsorship identification rules in April to target situations where a station broadcasts material sponsored by a foreign governmental entity. The new rules require disclosure of leased programming sponsored by foreign governmental entities.
The commission said its modified regulations further the critical goal of transparency and it applies them to foreign governments, political parties and their agents.

FCC Grants iHeart Petition on GMEI Foreign Investment
The FCC Media Bureau has okayed a petition from iHeartMedia regarding foreign investors that hold its stock.
iHeart had asked the bureau to approve foreign interests held by Global Media & Entertainment Investments Ltd. and related entities totaling 6.8% equity and 8% voting interests in iHeart. It also asked for advance approval for GMEI and its entities to increase those interests up to 14.99%.
In an earlier 2020 ruling, the bureau had authorized up to 100% overall foreign investment in iHeart; at the time it approved two groups to hold more than the usual limit of 5%. The PIMCO Group could hold up to 32.99% of equity and 19.99% of voting interests while the Invesco Group could hold up to 19.99% of equity and voting. In making those rulings the FCC said iHeart would need its approval for any further foreign investment above 5%.
But then iHeart said it learned last February that GMEI — formerly called Honeycomb Investments Ltd. and based in the Bahamas — had independently acquired about 9.6 million shares of its stock on the NASDAQ exchange, about 6.6% of equity and 8.7% of voting interests.
iHeart notified the FCC and sought approval for those percentages, plus advance approval for GMEI to go up to 14.99%. (GMEI itself asked for approval to go up to 49.99% but later withdrew that request and fell back to the 14.99% figure.) iHeart said this ruling would incentivize foreign investment and benefit U.S. trade policy by encouraging reciprocal investment opportunities for U.S. companies abroad. It also said GMEI represents no national security or law enforcement concerns.
[See Our Business and Law Page]
So in short the latest FCC ruling grants approval for GMEI and its related entities to hold more than 5% of iHeart’s equity and/or voting interest as well as advance approval to increase its interests up to 14.99%. The previous approvals also remain in place: aggregate direct and/or indirect foreign ownership of iHeart above the usual 25% benchmark is allowed up to 100%; (2) approval for the PIMCO Group to hold up to 32.99% of equity and 19.99% of voting interests in the company; and (3) approval for the Invesco Group to hold up to 19.99% of the equity and voting interests.
The Media Bureau took input from a federal advisory committee on foreign participation, which found no concerns. iHeart will still have to obtain approval for additional foreign investors to hold more than 5% (or 10% for certain institutional investors).
iHeart estimated that following the FCC’s approval, direct and indirect foreign ownership of its capital stock would be “at a minimum, approximately 30% as to voting and 40% as to equity.” But that would not be an issue given the FCC’s previous ruling permitting iHeart aggregate foreign ownership up to 100%.

FCC OKs Smaller Pre-Approval Percentage Of Global’s iHeart Stake
An effort by iHeartMedia to cap the FCC’s advance approval of any investment in the audio content and distribution giant by Michael Tabor-controlled Global Media & Entertainment at just under 15% has proven successful.
As such, GMEI, which bankrolls some of Great Britain’s biggest radio brands, will not get pre-approval from the Media Bureau to hold up to 49.99% nonvoting interest in iHeart.
But, GMEI withdrew that request in some six weeks ago.

CES Withdrawals Increase as iHeartMedia Cancels Key Event
Updated at 11:30am Eastern
On February 11, 2020, RBR+TVBR offered its first coverage of the COVID-19’s impact on the global broadcast media world. At the time, the report on how the owner of KHTS-FM in Santa Clarita, Calif., Carl Goldman, and his wife and travel companions were among the thousands of quarantined passengers aboard the Diamond Princess in Yokohama, Japan, was questioned by some readers as being too peripheral to the business of broadcast media in the U.S. The pandemic, to these industry figures, was seen as a largely Asian concern.
Nearly two years later, COVID-19 remains a global threat, thanks largely to the Omicron variant. And, with days until CES 2022 commences in Las Vegas, COVID-19 is now placing that mega-conference’s attendees on high alert — especially now that several high-profile companies have withdrawn, including the biggest audio content and distribution company in the U.S.
According to the New York Post, CES 2022 is not in danger of a full-blown cancellation, at least as of Tuesday evening (12/21). The report came just hours after RBR+TVBR reported that NAGRA is adding virtual meetings to its CES 2022 action plan. “As many people are not attending CES, NAGRA is scheduling virtual meetings to share their news,” the portable audio recorder company based in Switzerland said.
By Wednesday morning, the “On The Money” columnists at the newspaper learned that Nvidia, JPMorgan, and PepsiCo are each withdrawing from CES. The cancellation of Nvidia from CES is particularly unsettling, given their traditionally major presence at the technology conference and expo.
For broadcast media, iHeartMedia told the New York Post columnists they, too, will not attend CES 2022.
It is now known that the company’s iHeartRadio “Live @CES” in partnership with Medialink has been scrubbed. In a statement, iHeartRadio said, “We were looking forward to seeing you at our iHeartRadio Live at CES party at Area 15 on Thursday, January 6, 2022 to share a special performance by Swedish House Mafia — but to keep our friends and partners safe during this unpredictable time, we’ve made the decision to cancel the event.”
While unconfirmed, RBR+TVBR hears key iHeartMedia executives will still be in attendance at CES 2022 and that only this event has been cancelled. It marks the second time a radio industry event featuring Swedish House Mafia has been impacted, as it had been the closing performer at the Audacy Beach Festival on December 5 in Fort Lauderdale, only to be removed from the bill less than 24 hours before showtime due to COVID-19 exposure among members of the act or its tour team.
Meanwhile, the “On The Money” team says journalists from CNN, Forbes, TechCrunch, Engadget, MarketWatch, The Verge and The New York Times’ Wirecutter feature are also not planning to attend CES 2022.
The Post report coincides with a CNET story noting that T-Mobile, Twitter and Meta are also withdrawing from CES 2022.
While these high-profile withdrawals are generating headlines, CES 2022 remains a go. As such, the Jacobs Media Strategies “VIP Private Tour” is on schedule for Thursday, January 6 at 2:30pm Pacific at varying costs for clients and non-clients. “Our 90-minute private tours are limited to 15 guests and led by an expert employed by the CTA,” Jacobs Media says.
From 5-7pm Pacific on January 6 is the CES 2022 Radio Reception, located at the Bellagio Las Vegas Resort & Casino. The invitation-only event is co-presented by Radio Ink and Radio + Television Business Report in partnership with Beasley Media Group, QUU, Xperi, Benztown and vCreative.
CES requires proof of vacination.
Kenyan Authorities Begin Reclaiming Frequencies
Kenya’s Communications Authority is beginning the process of reclaiming unused frequencies across the country. CA Director-General Ezra Chioba made the announcement Dec. 22., saying the applicants and license holders have 30 days to bring their operations into compliance or their license would be cancelled.
According to The Standard newspaper in Nairobi, Chioba, who was appointed director-general in September 2021, came into office with an eye towards reforming Kenya’s regulatory framework for broadcasting. As part of this, he said the CA would begin repossessing unused broadcast licenses with the intent of redistributing them to new investors.
“We have in the last few weeks we reviewed and identified those culpable. Accordingly, we have decided to revoke target licenses. This will allow us to re-plan and re-allocate these resources to investors who demonstrate commitment to establish and offer viable broadcasting services,” Chioba said, according to The Standard.
[More Radio News from Around the World]
In the notice posted to the CA website, six groups of revocations are outlined, including the cancellation of license offers and revocation of FM frequencies for 60 broadcasters. That list includes large commercial stations like Capital FM, NRG Radio, and Mbaitu FM.
The frequencies in question, in some cases, are for additional transmitters, so the revocation does not mean that all the stations will leave the airways entirely.
In its report on the revocation, Capital FM’s owners stated: “We wish to assure our loyal listeners, clients and other stakeholders that the Management of Capital Group Limited is seized of the matter for total compliance,” using a legal phrase to say they were looking to ensure compliance.
In addition to the 60 license offers, the CA announced the revocation of four frequency assignments to license holders and 18 FM frequencies assignments to non-permit holders who had yet to apply for broadcasting licenses, as well as the rejection of 24 applications for commercial and community radio services who had yet to comply with licensing requirements including paying regulatory fees. Nineteen television licenses and three subscription-based broadcasting services were also marked for revocation of license offers for failure to act within the CA’s prescribed timeline.
Last year, Kenyan authorities announced plans to crackdown on “absentee” license holders and transfers of licenses without prior regulatory approval.

CKSP Initiates Service via Diplexed AM Directional System
The Dec. 22 issue of Radio World features our Buyer’s Guide for antennas, RF support and power products. Buyer’s Guide features application stories like this one.
CKNW(AM), a 50 kW station at 980 kHz, is an existing four-tower directional array located near Surrey, to the southeast of Vancouver, British Columbia, Canada.
CKSP, a 600 kHz, 50 kW DA-D, 20 kW DA-N station operated by Sher-E-Punjab, a broadcaster specializing in South Asian news/talk content, was added to the site making use of two of the four towers. It required a diplexed directional antenna system designed and fabricated by Kintronic Labs to facilitate the simultaneous operation of both stations from the CKNW transmitter site.
According to Tom King, president/CEO of Kintronic Labs, project management of the diplexed AM directional antenna system project was conducted by Richard Sondermeyer of G.S.Broadcast Technical Services Ltd. of Mississauga, Ontario. Final commissioning was conducted by Rob Elder, the Kintronic Labs field engineer.
The existing CKNW four-tower array is in the shape of a parallelogram, with two diagonally opposing towers oriented along a north–south line, and the other diagonally opposing towers oriented along a line rotated roughly 50 degrees clockwise from the center of the north–south line.
The NW tower is also the closest to the transmitter building, and its ATU building houses the CKNW power division/phasing networks as well as the tower matching network for this tower. The two towers on the north side of the array are those used for the new 600 kHz system, with the towers on the south side of the array detuned for 600 kHz.
The 600 kHz phasing and matching system was installed in a separate container located south of the CKNW transmitter building. The CKSP matching, filter and detune cabinets were installed in weatherproof housings and mounted on wooden platforms at the base of each of the towers.

Readers Celebrate Ham Radio
The following are in response to the Mark Persons article “Alike but Not Alike: Broadcast vs. Ham Radio.”
Well saidHaving been an amateur radio operator for more than 67 years (and an occasional contributor to Radio World), I want to compliment Mark Persons on his article in the Oct. 27 issue.
It is the best explanation of the amateur radio hobby that I have ever read. There is nothing more that I could add to describe “hamming” to both the technical and non-technical, and I will rely on it to explain and recruit more hams to our hobby. 73.
John Seibels, K4AXV
Remembering the magic
I was a broadcaster first for a number of years and didn’t get licensed in amateur radio until 1990. In the early years, it seemed that many of the engineers I worked with were hams. Maybe not so much anymore. But one of them proved a worthy “Elmer” to me and got me up and running on ham over 30 years ago.
There are indeed many similarities, at least in the technical aspects. When I started in broadcasting, a Third Class License was required. Every person overseeing an air shift needed to take transmitter readings to ensure compliance in power output. Other “off-air” duties included making sure we powered down or up at the appropriate times to sunrise or sunset, check the tower lights and other similar tasks.
As time went on, the Third Class requirement was dropped, as were the requirements of the broadcasters to be knowledgeable of power readings, and such.
They were fun years: two turntables, three cart decks and a microphone staring you in the face. No automation, no computers. Even having time to use the bathroom on a six-hour shift was pretty much limited to the 4½-minute UPI news feed at the top of the hour.
My last years in broadcasting were distilled down to recording cuts and saving them with specified file names.
Of course, ham radio is more recreational. The content is not controlled by a station log but by the person on the other end of the QSO.
But there was still the magic of being on the other side of a microphone. If conditions were good, it was not unusual for me to work a number of QSOs before and after being on the air as a broadcaster.
I am grateful for the broadcast engineers I’ve known over the years, keeping us on the air with our broadcast stations as well as helping me get into ham radio. 73.
Scott McIntire, K7DXT
On the same frequency
I live in the Washington area and have been a pro broadcaster since 1979, but I didn’t jump into amateur radio until 2009. When I did it was with both feet. I even changed my ringtone on my cellphone to the Morse characters CQ, which hams use to call out over the air to talk to other hams.
As a frequent commuter bus rider, I often have to transfer at the Pentagon bus depot. Many of my fellow passengers are military folks who disembark there for their day of duties.
One morning my phone rang — “dah-dit-dah-dit, dah-dah-dit dah.”
I heard a loud guffaw went up from the back of the bus. One of the other passengers — either a ham or part of the Signal Corps — recognized the pattern and got my joke.
Broadcast radio and ham radio. Love ’em both.

Workbench: The importance of microphone cable shields
John Schmidt, P.E., is principal of John Schmidt Audio Video Systems Design in Hempstead, N.Y. For 36 years until retirement, he worked for ABC Television in New York as a senior audio video systems engineer, designing and supervising the installation of audio systems.
After reading a recent Workbench column, John offered a few suggestions to help the uninitiated create more problems than they solve when working with microphone cable shields.
Individuals involved in connecting analog audio equipment should familiarize themselves with two Audio Engineering Society standards: AES 48 and AES 54. These describe best practices in dealing with cable shields.
John’s first suggestion based on the guidelines is that the microphone cable shields need to be connected — typically to Pin 1 of an XLR connector, as seen in Fig. 1 — in a continuous, preferably isolated path from the mic to the input of the mic preamp.
Pin 1 is considered ground on a three-pin XLR.Keep in mind that mics that utilize phantom power will not work without a shield (Pin 1) connection, as the cable shield provides a return path for the phantom power that operates the electronics inside the microphone.
Even if the mic does not use phantom power, failure to connect the shield may leave the mic circuit subject to hum or buzz due to capacitive coupling to one or the other of the active conductors, or interference due to RF pickup.
Now the issue moves to the line-level interconnects. Here there is a conflict between the practicality of the interconnecting equipment — which may not have been designed with best practice for grounding the shield connection (Pin 1 on the XLR) at the equipment interface — and requirements for RF immunity.
If all equipment was designed with proper termination of the shield connections for both its inputs and outputs, in accordance with AES 48, one would be advised to connect the shields of all input and output cables where they interface with the equipment at both ends. But as many of us have learned, this sometimes creates hum in the form of a ground loop.
At the expense of losing some RF immunity, connect the shield at only one end.
[Check Out More of Workbench Here]
If breaking the shield at one end solves your hum/buzz issue but leaves the equipment RF susceptible, try connecting the unterminated end of the shield to the metal case of the equipment through a small capacitor.
Transformer boxes can be useful, but John recommends specifying transformers with internal shields between the windings. Otherwise the capacitive coupling between the windings can pass interference.
Also keep in mind that some transformers have very poor frequency response when fed from a low-impedance source. If your circuitry is unbalanced, with the shield grounded at both the output and the input, and is carrying the return side of the audio signal, all bets are off, and you may really have a ground loop.
Finally, regarding analog video: Yes, the coax is fed with an unbalanced signal; however, most professional video equipment uses differential receive amplifiers, where the shield of the input is not grounded. The same is true for the unbalanced “composite” input of many FM exciters.
As readers can see, this is not a trivial issue.

A better way to modelOn Oct. 29, Radio World reported on a proposal by Dielectric and other antenna manufacturers to allow computer modeling of FM directional antennas.
The FCC has opened a notice of proposed rulemaking to take industry comments about this. It says more than 2,000 full-service FM stations, more than 20 percent of them, use directional antennas. The change would allow any of them that replace existing antennas to avoid the expense of field measurements. It would apply not only to applicants for new FM facilities but to FM licensees applying for facility modifications.
An image from the Dielectric presentation to the Broadcasters Clinic about computational modeling of FM directional antennas.John L. Schadler, a friend and former co-worker of mine when I was at Dielectric, outlined the studies that support this proposal in a presentation for the Broadcasters Clinic in October.
John’s presentation is available online and is fascinating. Of particular interest are the computer simulations John shows of FM coverage. Adjustment of parasitics or spacing yields nearly instantaneous display of the FM coverage pattern. These measurements, done physically on a range or in an anechoic chamber, currently take hours or days. In just a few minutes, patterns can be reliably modeled, modified or adjusted to meet coverage restrictions.
Final thoughtKuala Lumpur engineer Paul Sagi has followed our discussion of converting to LED lighting. He writes that heat is not the only enemy of LEDs; the wrong type of power supply can also shorten their life. LEDs work best on a constant current supply, rather than a constant voltage supply, which can also reduce their service time.
