It’s the radio interview that went on and on …. and on. And that’s a good thing.

On Feb. 5 and 6, 2022, two DJs at WJCU(FM) on the campus of John Carroll University broke the Guinness World Record for longest consecutive radio interview.

The program started at 7 am on Feb. 5 and ran live until 8:35 a.m. the next morning, capping a 25-hour, 35-minute-long interview. The program aired on 88.7 FM in Cleveland, on Instagram Live, via the WJCU radio app and on Twitch.

The record-breaking event was led by two radio staff — Zachary Sinutko and Collin Kennedy — who serve as on-air personalities as well as executive producer and co-producer, respectively, of the station’s hip-hop/rap show “808s and Mixtapes.”

“It was so much fun and college radio is my life,” said Sinutko, who is also director of promotions and events at the station. “Doing this was a dream of mine for a long time.”

Ahead of the attempt, Sinutko expressed confidence in their ability to break the previous record. “Two college students + a ton of energy drinks and a passion for college radio = countless possibilities,” he stated on the station’s website.

The previous record was set by Bhanu Bhakta Niraula on Nov. 8, 2021, at Himal FM 90.2 MHz in Kathmandu, Nepal, with a 25-hour, 26-minute-long interview of Nepalese tourism expert Ang Phinjo Sherpa.

Sinutko said official auditors were present at the event at WJCU, which broke the previous record by nine minutes.

“It got hard in the middle of the night but with the help of the community and the rest of the university, we did it,” said Kennedy. “Thank you to the school and to everyone who passed by the WJCU studio to help encourage us to do the unachievable.”

WJCU is a noncommercial FM broadcast station owned and operated by John Carroll University with studio and transmitter facilities located on the JCU campus in University Heights, Ohio. The station operates on a non-stop schedule with an effective radiated power of 2.5 kW at 88.7 MHz.

The author is vice president of engineering, Dielectric LLC. This article is based on a paper prepared for the NAB Broadcast Engineering and IT Conference of the NAB Show and is published with permission. Proceedings of the conference are available at https://nabpilot.org/beitc-proceedings/.

Abstract: There are approximately 900 Class A directional FM stations licensed in the United States. Many reasons exist to directionalize an FM antenna, including maximizing signal coverage over a designated market area (DMA), reducing lost signal over unpopulated areas, shaping the pattern to fit within the station’s authorized footprint and conforming to the rules stated in Title 47 CFR 73.316.

Currently, applications proposing the use of directional antenna systems must include a tabulation of the antenna pattern through measurements performed on a test range of either full scale or 4.4:1 scaled model setup.

It has been requested that the FCC acknowledge that the public interest will be served by the commission accepting computational modeling of directional FM antennas in lieu of physical measurements of antenna characteristics and/or performance for purposes of applications and licensing.

Products such as Ansys HFSS are 3D electromagnetic (EM) simulation software tools for designing, simulating and evaluating high-frequency electronic products such as antennas, antenna arrays and RF or microwave components. The use of 3D high-frequency simulation will in many ways yield results that are superior to traditional range measurement proofs, in terms of accuracy.

Since simulations are done in a true free-space environment, any issues with the range or anechoic chamber and with the surrounding environment are eliminated, resulting in more reliable azimuth patterns and H/V ratio.

The use of software also eliminates the lengthy setup and take down time of models as well as the need for a technician to adjust the model and take data points by hand, thus removing mechanical tolerances and human error affecting the data.

Another advantage of designing in a virtual environment is that the geometry can be completely optimized and not compromised by time, materials and tolerances.

This paper will go into detail on the many benefits illustrating why the FCC should authorize the use of 3D high-frequency simulation computer modeling to demonstrate that a directional FM antenna performs as authorized.

Introduction
The rule for licensing of FM directional antennas is found in §73.316(c)(2) and §73.316(c)(2)(iii) of Part 47 of the Code of Federal Regulations. It states that applications for license upon completion of the antenna construction must include a tabulation of the measured relative field pattern.

Read literally, since it asks for a tabulation of the measured relative field pattern upon completion of antenna construction, this language would seem to imply that an FM antenna must be measured after installation, through field measurements of the installed antenna, which can be quite impractical to make and would have been more so at the time that the rule was adopted in 1963.

Consequently, we assume that the rule was interpreted initially to require that FM directional antennas be measured on full-size test ranges, since such ranges were available then for characterizing both the azimuth and elevation patterns of broadcast television antennas.

In 1976, Matti Siukola, RCA scientist and unit manager of advanced development for RCA Broadcast Systems, presented his paper “Pattern Optimization of FM Antennas” at the NAB symposium.

Siukola proposed parasitic elements to be used as directors or reflectors in either horizontal or vertical positions to directionalize a simple FM antenna. In the same paper, Siukola also proposed the more economical use of scale modeling.

It has now been 45 years and basically nothing has changed regarding FM broadcast pattern verification. Interestingly, characterization of azimuth patterns has evolved in all other broadcast services such as AM radio and television.

The commission has a history of accepting computer modeling
The procedures required or allowed by the FCC for characterization of antenna azimuth patterns vary quite markedly between broadcast services: AM radio, FM radio and television.

It is notable that, while the rules for directional antennas for FM and TV were similar at their initial publication in 1963, there were a few significant differences between them that have led to different procedures over the years.

The most significant difference between the two approaches to directional antenna rules was that the FM rules required a “means (such as a rotatable reference antenna) whereby the operational antenna pattern will be determined prior to licensed operation and maintained within proper tolerances thereafter,” while the TV rules had no such requirement.

So, while the FM rules required a method for producing a “proof of performance” on the antenna prior to its use and for its maintenance over time thereafter, the TV rules did not.

The main difference between the two sets of 1963 rules is that the FM rules require that measured pattern performance data for a directional antenna be submitted as part of the application for a license to cover the corresponding construction permit once the antenna has been installed. The current TV rules (including the DTV rules) only require pattern data for a construction permit and don’t define whether that data must be derived through measurements or can be the product of calculations. The real-world results of this rule difference are that directional TV antennas and their patterns are specified almost exclusively using calculations, which, over time, have migrated to computational modeling of the antennas.

When comparing the three fundamental broadcast services and the treatment of their directional antennas in the commission’s rules, the AM antenna rules were updated over a decade ago.

In 2008, use of the Method of Moments (MoM) computer modeling, based on the Numerical Electromagnetic Code (NEC), was permitted as pattern verification for AM services. This approach provides considerable savings in time and cost for antenna manufacturers and ultimately for the broadcasters who purchase the antennas.

As discussed above, the TV/DTV rules already are flexible enough to permit use of computer modeling both for the design of antenna patterns and for the testing of the antenna’s performance without the need for physical models. That leaves only directional antennas for FM broadcasting with the requirements and burdens of having to go through the steps of first building models of antennas, measuring those models and collecting the related data.

RF Computer Modeling Outside the Broadcast Industry
Not only has the commission approved software modeling for AM directional antenna array proof of performance, but it has approved proof of performance for medical devices and RF radiation exposure evaluation of portable devices as well.

The high level of accuracy that simulation software provides has allowed a wide range of RF device manufacturers to significantly reduce the cost and time associated with proof of performance to the commission.

Computer Modeling — Repack
The timeline of the broadcast repack created a unique situation in the industry. Since many broadcasters needed new antennas and RF systems in a short amount of time, creative engineering solutions to reduce lead time had to be found.

The adoption of 3D high-frequency simulation to gather impedance, phase and amplitude data allowed for expedient antenna design and eliminated many limitations. This process has been successfully used at Dielectric to design more than 1,000 antennas since the beginning of the repack.

In addition, electrical design time was reduced from several weeks to less than three days. The manufacturing space needed to store physical models and house anechoic chambers has been repurposed to further accommodate manufacturing needs. This process has proven to produce more accurate designs, which is evident in the reduction of test time needed to bring the full antenna into specification.

It is safe to say that, without the use of virtual simulation, it would have been essentially impossible to design, manufacture, test and install the nearly 1,000 antennas that had to be replaced to complete the Post-Incentive Auction Spectrum Repack in the minimal time allowed for the process.

Fig. 1: DCR-Q Quadrupole FM-style antenna designed and manufactured for Channel 3 during the repack.

It is worthy to note that, in the television spectrum repack, as some TV stations moved from UHF to Low-VHF, they needed new directional Low-VHF antennas. In several cases, the designs used were those of FM directional antennas scaled to be larger, to work at the lower frequencies of TV Channels 2.6.

Because they were to be licensed for use by TV stations, the new Low-VHF antennas could be developed and proved with all the latest computer modeling techniques for design, manufacturing and testing. Had those very same antenna designs and patterns been constructed for the purpose of use a few MHz higher, in the FM band, only because of the differences in the FCC rules, it would have been necessary to physically model them prior to building them and to physically measure them to collect data for submission to the FCC during the licensing process.

Fig. 1 shows a quadrupole ring antenna typically used for FM broadcast design for the use at TV Channel 3.

Range Measurement Accuracy
An important part of range antenna pattern measurements is the alignment and reflectivity of the range. Alignment typically relies on mechanical bore sighting with the assumption that the antenna used to transmit the signal to the device under test (DUT) is perfectly electrically aligned. Alignment accuracy is therefore limited by both mechanical and electrical constraints.

The principle reason for the pattern to deviate from what would be expected from an idealized range are reflections from the range surface, surrounding objects, the positioner and the cables used to feed the antenna. Sometimes signals from external sources also pose a problem. The field at a point in the aperture under test is the phasor sum of the test signal and the extraneous signals. The relative amplitudes and phases of the desired and extraneous signals will vary with position along the test aperture causing constructive and destructive additions, thus producing a measured pattern that will depart from the free space expected pattern. (See “National Association of Broadcasters Handbook, 11th Edition,” 2018. Chapter 10.8, “VHF and UHF Television Antenna Test Range Measurements,” John L. Schadler.)

Fig. 2: Range measurement error.

Range measurement accuracy limitations are removed with the use of computer simulation.

Mechanical Tolerancing and Human Error With Physical Modeling
Software eliminates lengthy setup and take down of models as well as the need for a technician to be physically present to adjust the model and take data points by hand. Accuracy is improved greatly using simulation as it removes mechanical tolerances and human error affecting the data. Information that is traditionally recorded by hand, such as radiator location and parasitic sizes and locations in space is replaced by a simple exportation of the computer model. The full three-dimensional model can be sent directly to 3D CAD software for detailed component manufacturing and installation instructions, eliminating the possibility of documentation error and physical measurement inaccuracies.

Automated Optimization
Another advantage of designing in a virtual environment is that the geometry can be completely optimized and not compromised by time, materials and tolerances. Variables can be automatically adjusted, and complete data tables exported for the next step in the design process. This is done through an artificial intelligence. An optimetric setup can simultaneously solve any combination of pattern shapers, parasitics and radiators positions in space to find best fit solutions. Trial and error techniques traditionally used to develop the geometry necessary to produce a desired pattern is replaced by this artificial intelligence optimetric process. Criteria are set based on the desired azimuth and FCC regulation and multiple antenna configurations can be run in parallel to reduce overall study time.

Significance of Polarization Ratio
The rules under 47 C.F.R. §73.316 state that the supplemental vertically polarized effective radiated power (ERP) required for circular or elliptical polarization shall in no event exceed the effective radiated power authorized.

Since in most cases, broadcasters consider the vertically polarized component more important than the horizontal and tend to maximize their vertical signal, accurate polarization measurements are important.

Range measuring the polarization ratio at any point in space with accuracy is difficult. Since no range is completely free of reflection and the fact that horizontal and vertically polarized waves reflect differently, the accuracy in the ratio is limited by the range reflectivity. Polarization ratio range measurement accuracy is also limited by the transmit antennas horizontal and vertical polarization pattern congruency.

If the transmit antenna is linearly polarized and is spun from horizontal to vertical for polarization tests on the DUT, the assumption is that the beam is perfectly straight and has no wobble. If separate radiation paths are used to measure the polarizations, such as switching between crossed dipoles, the assumption is that each of the patterns and gains of the two paths are identical.

Each of these sources for error is eliminated with the use of 3D high-frequency simulation.

Comparison of Physical Model Measurements and Computational Simulation
To show the validity of computer modeling in place of physical modeling of FM directional antennas, an example design using both methods, i.e., physical modeling and computational modeling of the same antenna, are compared.

Fig. 4: A 4.4:1 scaled model antenna test.

In the example design, a directional pattern study for Station WHEM, 91.3 MHz, Eau Clair, Wis., was performed on a scale model FM test range using a scaling factor of 4.4:1 for all elements involved in the study.

The scaled elements included a model of an antenna bay and identically scaled models of parasitic elements and the mounting pipe to be used by the station. All the scaled model components were rotated through 360 degrees while receiving a signal at the appropriately-scaled frequency from a linear cavity-backed source antenna.

The horizontally and vertically polarized azimuth patterns were measured in an anechoic chamber test range. The signal source and scale-model antennas were mounted at identical elevations and at opposite ends of the test chamber. A network analyzer was used to supply the RF signal to the source antenna at 4.4 times the fundamental FM frequency (i.e., at 401.72 MHz) and to receive the signal intercepted by the antenna under test.

A photograph of the scale-model pattern study configuration is shown in Fig. 4.

Fig. 5: HFSS model used for simulation.

This directional pattern study was replicated in the Ansys HFSS environment using the full-scale CAD model of this antenna bay, mounting pipe and parasitics at the fundamental frequency of 91.3 MHz six years later. See Fig. 5.

The original results of the scaled model directional pattern study were accepted by the customer and demonstrated both proof of performance and FCC pattern envelope compliance in both the horizontal and vertical planes. A statistical measure of the relationship between two sets of data can be analyzed using the correlation coefficient (r). A correlation coefficient of r = 1.0 represents a perfect match. It can be used as the figure of merit to determine how closely the range measurements match the HFSS calculations.

Where:
xi = x values in sample
x̅ = mean of the x value samples
yi = y values in sample
y̅ = mean of the y value samples

Fig. 6 displays the overlaid horizontal and vertical polarization patterns and the FCC pattern mask. As can be seen, the results of the Ansys HFSS directional pattern study very closely match the results of the scaled model study.

The horizontal polarization azimuth pattern for both the scaled model study and the simulated pattern study have a maximum deviation of 1.67 dB and a minimum deviation of –1.39 dB compared to the scaled model study. The correlation coefficient for the horizontal polarization is 0.986 and 0.960 for the vertical polarization. The figure also shows that the computationally simulated antenna exceeds the FCC pattern mask in the vertical polarization pattern by a minimal amount. It must be noted that if computer modeling was used in 2015 at the time of this study, modifications would have been made to bring the vertical component inside the FCC protect.

Conclusion
The tools that were available when the current rules for FM directional antennas were developed in 1963 only included full-size or scaled modeling of antennas, combined with physical measurements, to approximate the characteristics that would be obtained when an antenna was installed.

In the decades since then, computational methods have evolved to enable more accurate and precise predictions of the antenna performance. The FCC has for decades relied upon manufacturers of FM directional antennas with engineering personnel who can apply the necessary skills to design and test broadcast antennas. The basic knowledge, experience and expertise requirements with respect to antenna design and modeling remain the same when the newer computational modeling techniques are applied as was the case prior to their availability.

It therefore stands to reason that the manufacturers of FM directional antennas should be permitted to apply the new tools at their discretion and that the FCC should accept the results of computational modeling as being just as valid as the results from physical construction and measurement of either full-size or scaled models of antennas.

There’s a new effort afoot to develop a guideline for the use of metadata that accompanies audio streamed by radio stations.

The National Radio Systems Committee is a technical standards-setting body co-sponsored by the National Association of Broadcasters, representing the transmission side of the radio broadcast industry, and the Consumer Technology Association, representing the reception side.

The NRSC’s Metadata and Streaming Work Group, or MSWG, has a new chair, consultant David Bialik of David K. Bialik & Associates, succeeding Alan Jurison. That working group is part of a larger Data Services and Metadata Subcommittee, or DSM, chaired by Steve Shultis, CTO of New York Public Radio.

Bialik, whose articles about streaming and work at the AES are familiar to Radio World readers, will be responsible for leading development of NRSC-G304, a guideline for streaming audio metadata.

“David’s expertise in the area of streaming for broadcast audio will be put to good use as the new chair,” Shultis said in the announcement. “Radio broadcasters rely increasingly upon their audio streams and the NRSC is eager to help develop better standards in this area.”

The planned document is a guideline for radio broadcasters describing how to use metadata on the streaming audio versions of radio broadcast programs, Bialik told me.

“It focuses on the HTTP live streaming (HLS) method of audio streaming as this has become a de facto standard within the radio broadcasting industry.”

People who are interested in participating in this work should email David Layer at dlayer@nab.org.

The owner of an AM station in Idaho faces an FCC hearing to consider whether its license should be renewed.

The reason for a hearing, the commission said, is the station’s “record of extended silence and operation at significantly reduced power,” among other factors.

The station is KPCQ(AM) in Chubbuck, Idaho, broadcasting on 1490 kHz and licensed to Snake River Radio.

If a broadcast station is silent for any consecutive 12-month period, its license expires. However, Holly Saurer, the new chief of the Media Bureau, noted in her order that some licensees of silent stations will resume operation for a short period before the one-year limit applies, to keep a license from expiring. Others have alternated between periods of silence and operations at very low power levels.

The commission appears to believe that was the case here. It says that from Feb. 1, 2018, to Oct. 1, 2021, the station was silent for 1,339 days or 80% of the time.

[See Our Business and Law Page]

SRR reported that it initially went silent when the site owner required it to remove its tower on June 30, 2018.

However, on June 26, 2019, the company filed a notice of resumption stating that the station had resumed operation on June 15 using its licensed facilities. “Because it is improbable that SRR was able to resume operation with the station’s licensed facilities after dismantling its tower, we are designating an issue to determine whether the station’s license expired … because the station failed to operate with its authorized facilities for more than 12 months.”

The station went silent again on June 17, 2019, when according to SRR a construction crew severed a tower guy wire, causing collapse of the tower. “This is also not explained in the Renewal Application.”

On June 24, 2019, SRR filed an application for construction permit to change site, which was granted.

On June 14, 2020, the station operated for one day, using a temporary long-wire facility. But it went silent again when that facility was destroyed by a construction crew, SRR wrote. It requested extension of silent authority because it was still constructing its new facility.

The FCC says the station remained silent until June 14, 2021, when it resumed operation under program test authority prior to filing its license application to cover the CP. It has operated since while a license renewal application, filed in 2020, is pending.

But now the Media Bureau, citing those extended periods of silence and questions about whether the license had expired automatically, says it is “unable to find that grant of the renewal application is in the public interest.” So it has designated the case to go before an FCC administrative law judge.

The commission instructed Snake River Radio to notify it within 20 days about its intention to appear and “avail itself of the opportunity to be heard and the right to present evidence.”

Asked for comment, SSR’s Managing Member Ted Austin told Radio World: “It is unfortunate that the loss of the station’s original tower site, COVID and the impact of digital media on the advertising revenue of small stations such as KPCQ(AM) has resulted in the FCC taking this action, but Snake River Radio LLC intends to provide the FCC with information that hopefully will preserve the license and allow SRR to truly serve the public interest of Chubbuck in the near future.”

“Completely one-sided.” That’s how Curtis LeGeyt describes the proposed American Music Fairness Act, or AMFA.

In a blog post, the new president/CEO of the National Association of Broadcasters says the latest performance royalty legislation would “hurt the very artists that it claims to help by having a profound effect on one of their most impactful outlets: local radio stations around the country.”

The issue is active again on Capitol Hill, as we recently reported.

“Just like some artists, thousands of radio stations around the country are struggling in the aftermath of a pandemic. Stations across the country could pay hundreds of thousands of dollars in new royalties,” LeGeyt wrote.

“Even the AMFA’s ‘starter fee’ would absolutely impact their ability to pay salaries, utility bills and cover local news, and that the fee will only get larger in the years to come.”

The latter remark refers to a provision that small broadcasters would be limited to annual payments of $500 and qualified public, college and noncom stations would pay $100.

LeGeyt says the bill addresses only one aspect of what should be a broader discussion. “A system as complex as the music licensing regime that for years has allowed artists, record labels and radio stations to thrive, deserves a holistic look if it’s no longer serving the interests of those who depend on it.”

He repeated criticism of the artists and labels that he had made in his recent hearing appearance. “It’s hard to dance when you don’t have a willing partner. The record label execs who criticize local radio while at the same time asking for airplay for their artists refused to engage in meaningful negotiations and repeatedly rebuffed every proposal we put on the table.” Read his post.

Advocates for a performance royalty are vocal about what they perceive as the injustice of the longstanding exemption for radio stations. Michael Huppe, president/CEO of SoundExchange, has said the lack of radio performance rights to artists or labels “is one of the most egregious injustices that exists today in the U.S. music industry.”

Gordon Smith in an image from the 2021 State Leadership Conference.

Gordon Smith, who recently stepped down as president/CEO of the National Association of Broadcasters, will receive the NAB Distinguished Service Award in April.

“It is an honor to present him with the Distinguished Service Award in recognition of the immense impact he has left on broadcasting in our country and around the world,” said his successor, Curtis LeGeyt.

The organization said that during Smith’s decade, the association “played a pivotal role on a number of significant issues affecting broadcasters, including the broadcast television spectrum incentive auction, preservation and modernization of the music licensing and copyright system, the ongoing transition to the NextGen TV transmission standard, reviews of media ownership rules and the increased dominance of tech platforms in the advertising marketplace.”

The award will be presented at the NAB Show Welcome session on April 25 in Las Vegas.

The award goes to a person “who has made a significant and lasting contribution to the American broadcasting industry.” David Sarnoff was the first recipient in 1953; Jim Henson is the most recent, given posthumously in 2020. Other recipients include Eddie Fritts, Cathy Hughes, Lowry Mays, Alan Alda, Dick Wiley, Jim Quello, and Robin Roberts, among others.

Smith is a former U.S. senator who practiced law in New Mexico and Arizona before returning to Oregon to direct the family-owned Smith Frozen Foods business in Weston, Ore. (His Twitter handle is @peapicker541.) He also served in the Oregon State Senate and was its president.

iHeartMedia Albany’s News Radio 810 and 103.1 WGY will celebrate the station’s 100th anniversary on Feb. 20.

WGY was founded by General Electric in 1922. Dame Media sold the station to Clear Channel, now iHeart, in 1999. “The Capital Region’s Breaking News, Traffic and Weather Station” will mark the occasion with a special broadcast and new podcast series.

According to a “list of firsts” on the station’s website, WGY was the first station in the state of New York; gave the first presentation of a radio drama in August 1922; was the first to broadcast at 50,000 watts (and at various times used two to four times that); aired the first World Series coverage, with WJZ; and made the first use of a condenser microphone.

Anniversary events kick off Feb. 20 with a live celebration of the brand’s history beginning at 1 p.m. Hosts and news anchors, past and present, and other guests will be on hand. A retelling of the radio drama “The Wolf” will be presented live from the Kenmore Ballroom in Albany, N.Y., [preceded by a lecture from Chris Hunter from the Museum of Innovation and Science. Music by the Musicians of Ma’alwyck chamber music ensemble will also be featured.

WGY kicked off its centennial year with a new podcast series, “Wireless: 100 Years of WGY.” The podcast, which features candid interviews with many familiar WGY voices, launched Jan. 31. It is hosted by WGY News Anchor Mike Patrick with new episodes released weekly.

Program Director Jeff Wolf was quoted in the announcement saying that leading the station into its next 100 years was an honor. “We’re looking forward to highlighting our first 100 years and commemorating important events in history throughout 2022.”

John Cooper, senior vice president of programming for iHeartMedia Albany, said WGY has had an impact on his life since the early 1960s. The anniversary of service to the community is an “amazing milestone,” he said.

“WGY became a trusted source of information that helped me begin and develop my business career,” said Howard Greiner, Area President for iHeartMedia Albany. “It is very meaningful to be a part of this celebration with great people, past and present, at WGY.”

The FCC clearly has been giving a lot of thought to the state of the Emergency Alert System.

The commission spent much of 2021 reviewing EAS for ways to tweak it, as mandated by Congress; and it has taken some steps, such as requiring State Emergency Communications Committees to meet at least annually and to submit plans for FCC approval. It is exploring other ideas such as internet alerting, as we’ve reported.

Another Notice of Proposed Rulemaking, opened at the FCC’s December meeting, deals mainly with video accessibility but has some radio implications. And a companion Notice of Inquiry asks about further changes that could affect EAS and radio much more broadly.

Better crawls
The EAS system consists of both the legacy broadcast infrastructure as well as an internet-based Common Alerting Protocol structure, which has better visual messaging capabilities.

In its NPRM, the FCC proposes first to clarify the visual crawl for legacy-based nationwide EAS tests — like the National Periodic test last August — by requiring TV stations and other video service EAS participants to use scripted text as opposed to constructing the visual crawl from the header code.

The crawl text would be “This is a nationwide test of the Emergency Alert System issued by the Federal Emergency Management Agency covering the United States from [time] to [time]. This is only a test. No action is required by the public.”

In its notice the FCC asks a series of questions about that proposal, including whether for reasons of consistency it should also apply to CAP-based nationwide EAS tests, or whether doing so would limit the flexibility of CAP alerts.

The commission then also proposes to change the terminology for the nationwide test event code or NPT from “National Periodic Test” to “Nationwide Test of the Emergency Alert System.” The NPT code itself would stay the same but the name seen by the public would be clearer.

The commission pointed out that FEMA separately has recommended a change in terminology for the PEP originator code from “Primary Entry Point system” to “National Authority.”

[Related: The FCC Studies Internet EAS Alerting]

If both of these changes were adopted, the FCC said, the minimum required information in a CAP-based nationwide test visual crawl would change from “The Primary Entry Point system has issued a National Periodic Test for the United States beginning at [time] and ending at [time]” to “The National Authority has issued a Nationwide Test of the Emergency Alert System for the United States beginning at [time] and ending at [time].”

It wants to know, among other things, if these changes will make the visual message for CAP-based nationwide EAS tests more understandable and informative, or if other language would be clearer.

Polling IPAWS
All of the above is aimed at video service providers but sets the stage for consideration of additional changes with more relevance to radio.

The second major proposed step in the NPRM is to require EAS participants, including radio stations, to “poll” IPAWS, the Integrated Public Alert and Warning System when they receive a legacy-based state or local area EAS alert, to confirm whether there was a CAP version available, and to process that alert instead. National Weather Service alerts would be included in this requirement. (NWS alerts are not currently sent on the IPAWS EAS feed.)

The goal is to promote the use of CAP and its capacity to provide matching visual and audio messages.

The FCC noted that EAS participants typically receive legacy and CAP versions of an alert at different times, and the rules don’t specify which version gets delivered. The rules do allow participants to check for CAP versions of state and local legacy EAS alerts but they don’t require it. Unless a station has programmed its equipment to check for a CAP version when it gets a legacy version, the equipment will process whichever is received first.

But CAP allows alert originators to relay enhanced text that can transcribe full audio messages, allowing visual messages that can match longer audio messages. And the FCC believes that any encouragement of the use of CAP versions is beneficial, because those alerts have more information, potentially including visual and audio messages that match.

The commission asks for feedback on that proposal, including whether it could be achieved via a software update and whether there are other ways to facilitate the use of CAP by alert originators with enhanced text that transcribes the verbiage in the audio message.

The FCC isn’t proposing to extend this proposed CAP prioritization mandate to nationwide EAS tests, which often are used to test performance in distributing a presidential EAN message under circumstances where only legacy EAS is available. But it did ask for comment on whether it should do so.

It also asks whether EAS participants should be allowed some minimum timeframe when polling IPAWS before determining that no CAP version is available. And it asked if its CAP prioritization proposal should include required monthly and weekly tests.

Longer view
Along with the NPRM proposals described above, the FCC issued a notice of inquiry, asking for comment on more steps that could improve the accessibility and utility of EAS. The commission uses NOIs as a way to create a dialogue about longer-term questions and possibilities that are not immediately on the table.

Again, much of the NOI’s discussion was about video yet it overlaps with radio interests.

The FCC points out that EAS is an audio-based system and that the legacy portion of the infrastructure was not designed with visual display of text in mind.

In legacy-based alerts, originators currently can generate an audio message that verbalizes the header code elements used to generate the visual message, so that the visual and audio messages match. But this approach may leave unused some of the two-minute allotment for the audio message. That extra time could be used to convey important information. But fully using the two minutes could mean that the visual information will not match the audio portion of the alert.

[Related: Carriers Report Success in National WEA Test]

So in the NOI, the commission asks whether legacy EAS should be modified to enable the distribution of enough text to transcribe the entirety of a two-minute audio message. This raises a technical question.

It notes that the legacy EAS uses AFSK modulation to convert data into audible tones, a process considered cumbersome. Using it to relay sufficient text to match the verbiage in a two-minute audio message theoretically would result in a tone that is roughly 30 seconds in length.

EAS participants have feared that longer alert tones could send listeners searching for the “off” button, or perhaps moving over to streaming providers, where there are no alerts (at least at present).

So the FCC asks: Would the public — not to mention radio and TV stations and other EAS participants — tolerate such a tone? Is there a better compression or modulation scheme that would deliver the necessary information, functioning across all EAS participant services and delivering live audio and maybe video? Is there a role for digital transmission standards such as ATSC 3.0 or HD Radio to improve EAS capabilities?

And last, the commission really goes broad.

It asks: Rather than focusing on ways to modify legacy EAS to relay text or CAP, would it make sense to use legacy EAS only for the Emergency Action Notification (EAN) and NPT, but require use of CAP for all other alerts?

And if legacy EAS can’t be reasonably modified to allow alert originators to distribute text to transcribe a two-minute audio message, should the legacy EAS architecture be redesigned altogether?

The commission noted that in 2012, when it adopted CAP EAS rules, it kept the legacy EAS because of its resiliency in the face of a national emergency and because there was no fully CAP-centric system in place to replace it. It now asks whether those factors “remain as true and relevant today,” and whether EAS could be redesigned to keep the resiliency and automation of legacy EAS but with the functionalities of CAP.

First thoughts
We asked some EAS observers for reaction to all of the above.

Harold Price, president of manufacturer Sage Alerting Systems, said requiring stations to poll the IPAWS server as described in the NPRM is an “automatic seek-and-fetch of the CAP message when the broadcast EAS version is received first.” He said it raises the possibility of delays, including timeouts of alerts and message duplication errors.

“It is possible the legacy message will be generated and transmitted via a state relay system before it is sent to or processed by IPAWS.”

However, he continued, the requirement could result in better audio quality.

On the question of whether the legacy EAS might be redesigned to enable distribution of text sufficient to transcribe a two-minute audio message, Price and some others expressed doubt.

“There is little chance of improving EAS by stuffing long multilingual text strings down a 65-character-per-second pipe,” he said.

Ed Czarnecki, vice president of global and government affairs for manufacturer Digital Alerting Systems, said, “The existing protocol enables us to create that short standard EAS message. The question is whether and how EAS can support more text. I think it’s safe to say that nobody desires a solution that results in overly long tone bursts over the airwaves to carry all that text.”

Czarnecki noted the proposed change of the PEP originator code to “National Authority” instead of “Primary Entry Point.”

“A software update for all EAS devices could handle this. If adopted, I’d hope that this proposal will provide enough time to allow for such a change to be slid into a minor software update.”

Czarnecki said the NPRM asks several questions that may pose issues for the radio industry. “For example, they ask whether it makes sense to only use legacy EAS for the EAN and NPT and rely on internet CAP for all other alerts, which could signal a less relevant position for radio broadcasting in general.”

He also noted that the FCC didn’t exempt radio stations from the proposal that EAS participants poll IPAWS.

“I think there is some good logic behind this. One benefit would be giving radio stations with access to first-generation CAP audio, when available, compared to second- or even third-generation audio from a conventional EAS message,” he said.

“Another indirect benefit for radio stations with newsrooms is that the expanded CAP text may also provide more detail and a fuller ‘story’ than conventional EAS messages.”

He said the company’s DASDEC equipment already has the capability, which it calls Triggered Cap Polling.

“Another use case for the FCC’s proposal comes to mind: multilingual,” he said. “If a multilingual CAP message is available, the use of Triggered CAP Polling would prompt a station to seek out that CAP message and use its contents instead. That content could include optional additional languages, in the case of a Spanish radio broadcaster, or any other provided language.”

Czarnecki does not agree with the idea to use legacy EAS only for the Emergency Action Notification (EAN) and NPT and require use of CAP for all other alerts.

“We’ve noted many times, including in our own filings with the FCC, that legacy EAS provides a resilient backup system when CAP over internet is unavailable for any reason.”

He cautions, “The reliability of our public warning architecture could be dangerously compromised if the FCC allows CAP-only monitoring without radio-based EAS at least as a backup.”

He said EAS manufacturers also have reservations about the FCC’s question about whether the legacy EAS architecture should be redesigned altogether.

“Triggered CAP Polling adequately addresses this question. The full text can be contained in a CAP message. If EAS is received first, that triggers the EAS device to poll IPAWS for CAP, and uses that message instead. If CAP or the internet is not available in an extreme situation, then at least the basic EAS message can be issued.”

Manufacturers believe there may be ways that EAS can be improved without a costly architecture redesign. However, the feeling is that discussion within industry might be more appropriate at this stage.

Czarnecki said, “The questions posed in the NOI are appreciated in that they are far-reaching. We’re hoping to confer with other EAS manufacturers about various technical issues that these questions raise.”

Microphone manufacturer Heil Sound has new top leadership for the first time in its 56-year history.

The Illinois-based company said Bob and Sarah Heil have transferred ownership to current President/CEO Ash Levitt and Director of Operations Steve Warford.

“Sarah Heil has retired, but Bob will continue to do outreach work and product design within the amateur radio space under the title Founder and CEO Emeritus,” it stated.

The company said Levitt and Warford each began working with Heil Sound as teenagers, building and packaging products. “Levitt took a different career path in academia for a number of years, but continued to regularly consult with Heil Sound during that time. He returned to the company full-time in 2017 and assumed the role of president in 2020. Warford worked his way up in the company during his tenure and has been responsible for daily operations for the past several years.”

An Early Photo of Bob Heil

Bob Heil began his audio career as a teenager performing concerts as the house player on the Wurlitzer theater organ at the Fox Theater in St. Louis. According to a company bio he was also deeply involved in ham radio and began tinkering with electronics and electronic design.

He opened “Ye Olde Music Shoppe” in Marissa, Ill., in the early 1960s and found success catering to professional touring bands. Heil Sound was formed in 1966 to provide pro touring gear and systems, and system design and equipment for music festivals.

Among his innovations is the famous Talk Box used by Joe Walsh and Peter Frampton, the quadrophonic mixer for the Who, and modular mixing consoles. The company entered mic manufacturing in the 1990s based in part on the prompting of Bob Heil’s friend the musician Joe Walsh.

In its announcement of the transition, the company quoted Bob Heil saying, “My life has been about achieving great sound, whether on the concert stage or in the amateur radio world. … This company has been my passion but it is time for me to step aside.”

An image from Dielectric shows a scale model of an antenna and an HFSS virtual version

The National Association of Broadcasters supports the idea of allowing computer simulations for FM antenna directional patterns — as long as certain guardrails are in place.

“NAB believes that computational simulation of FM directional antennas is already mature and can produce comparable accuracy to physical measurements, thus minimizing the potential for new interference,” it wrote in comments filed with the Federal Communications Commission.

But it cautioned that “electromagnetic modeling software is complex, can be subject to manipulation, and limited by the accuracy and completeness of the input data.”

In November the commission opened an NPRM on this issue and proposed to permit the modeling. The change was urged in a joint petition from Dielectric, Jampro, Radio Frequency Systems and Shively Labs, all of which make antennas, as well as broadcaster Educational Media Foundation.

The most common reason to use a directional antenna by a commercial full-power FM station is to allow it to “short-space” to another FM station while maintaining contour protection to that station.

[Related: “Dielectric Expects FCC to OK FM Pattern Modeling”]

NAB wrote in its filed comments that the accuracy of computer simulation is “fundamentally dependent on the accuracy of the data input to the software.” So the association urged the FCC to require that full documentation of the underlying data and its sources be available to the commission and to “interested parties upon request.”

It wants the FCC to require the following: a statement of the qualifications of the people responsible for modeling; a complete description of the antenna system; limits of 15 dB max/min in the azimuth plane and of 2 dB/10-degree rate-of-change in the azimuth plane; and certification by a licensed land surveyor or equivalent that the antenna is oriented properly and installed at the correct height.

On other aspects, the NAB said the FCC should not require “in situ” measurements beyond ensuring the proper installation of the antenna. The commission should accept results from any appropriate electromagnetic modeling software. And, NAB said, absolute accuracy is not practically achievable, so the commission shouldn’t try to attain prediction accuracies that don’t materially affect the interference environment.

The FCC Media Bureau has finalized a filing penalty against the winning bidder of an FM construction permit for Hugo, Colo., reducing the fine to $1,000 and calling the error a “minor delinquency.”

ScarboroughRadio LLC, a winning bidder in Auction 109, failed to file a post-auction Form 2100, Schedule 301 long-form application until a couple of weeks after the deadline last September.

Applications can be dismissed outright in such circumstances, the commission pointed out; but an applicant can establish good cause if “minor, inadvertent” post-auction delinquencies don’t disrupt its auction process or undermine its goal of facilitating rapid implementation of service.

[See Our Business and Law Page]

In issuing a notice of apparent liability in December, the FCC waived the deadline, saying that Scarborough had complied with its other obligations, there was no indication of bad faith and the late filing was a minor violation. That meant Scarborough could go ahead with its plan to add FM service to Hugo.

But the FCC did propose a $3,000 fine in the NAL. Company principal Scott Scarborough then filed a response, noting that he is a first-time auction participant, and that after working with the Media Bureau staff on preparation of the long-form application, “it was his understanding that there was no more to be done, that the filing was complete and that there were no issues regarding late filing.”

The commission now has issued a forfeiture order. It said auction bidders were informed through various means of the rules for the post-auction long-form application; but, it continued, Scarborough replied to its NAL promptly, made its final payment and met the other relevant obligations.

“These facts, combined with the fact that Mr. Scarborough proactively reached out to bureau staff to complete the late-filed application, support Scarborough’s assertion that its late application filing was wholly inadvertent.” For this “minor post-auction delinquency,” the FCC settled on a reduced forfeiture of $1,000.

The year 2021 was a quiet one for U.S. broadcast transactions, according to a new report, and radio station deal values were at their lowest point in at least 40 years.

According to a market deal recap, S&P Global Market Intelligence found that while broadcast station advertising revenue rebounded from the hit it took in 2020 due to the COVID outbreak, the station transaction market is sitting at near-historical lows.

Total TV and radio deal volume for 2021 was $4.72 billion. Radio represented only 4% of that; $190.2 million is the lowest value for radio transactions in the company’s records, spanning four decades.

The four largest radio station deals were driven by three of the country’s top-10 TV station owners.

[See Our Business and Law Page]

In June, Sinclair Broadcast Group announced the sale of its only radio stations to Lotus Communications for $18.06 million.

And late in the year, The Walt Disney Co. received $24.25 million for its remaining radio stations: VCY America will pay $9.25 million for KESN(FM) in the Dallas–Ft. Worth market, while Good Karma Broadcasting will pay $15 million for Disney’s AM stations in New York, Los Angeles and Chicago, along with an LMA for Emmis Communications station WEPN(FM).

Of the TV/radio broadcast total, about $4.2 billion or almost 93% came from the top two deals and their spinoffs.

In February 2021, Gray paid $925 million to Quincy Media for two TV stations and two radio stations. In April, Gray then sold 10 full-power and three low-power stations from the Quincy acquisition to Allen Media Group for $380 million. In May, Gray then announced the acquisition of Meredith Corp. and its 16 full-power and 30 low-power TV stations for $2.82 billion.

For the third year in a row, the average cash flow multiple for radio transactions remained stable at 6.6-times forward buyers broadcast cash flow. “In our estimates, only 25 full-power radio stations were sold based on their cash flow. That is, however, five stations more than in 2020.”

The author is a retired broadcast engineer who has been involved with advancing radio and television throughout his career, including for Qualcomm/MediaFLO, Harris, Nautel and ONEMedia LLC/Sinclair.

“I would like to see AM radio begin simulcasting on ATSC 3.0 signals. A single ATSC 3.0 transmitter could carry all of the AM signals in a market, in addition to TV programs.”

That was Dave Hershberger, quoted in a Radio World profile after his much-deserved receipt of the NAB Radio Engineering Achievement Award.

I think his proposition is worth considering.

In my opinion, the ultimate broadcast engineering experience is still an AM directional antenna array. That said, I smile politely when I hear talk of “AM revitalization.” At this point I think a deliberate, clear-eyed look at our much-loved industry leads us to reinvention over repair.

Medium-wave spectrum is far from “beachfront property.” For reasons that have been well documented — poor building penetration, increasing noise, dwindling receivers, aging demographics — the most likely future for AM spectrum is that it will continue to lose value to the point where launching something completely new, like high-power all-digital, makes sense.

The state of deployment of ATSC 3.0 by Nielsen TV market, from the Advanced Television Systems Committee. Areas in orange have at least one station “on the air,” though most have more than one. Those in light blue have stations planning service soon; those in dark blue are coming later in the year, at which point NextGen TV will reach 75% of the viewing public in terms of USA population.

FM’s low-VHF spectrum is closer to “beachfront property,” but even high-VHF is considerably better. Note that originally, FM was promoted as a replacement for AM, it was not promoted as an additional service.

Broadcasters also distribute their linear content via unlicensed and unlimited internet. This is all IP, so there’s no limitation on what can be broadcast, how it is packaged or how much bandwidth it takes.

While OTA broadcast covers unpopulated areas well, streaming is now available in virtually every populated area, building, tunnel, venue, etc., and there are few limits to how big the “coverage area,” can be, up to and including the entire planet.

Besides 5G, tiny IP satellites are coming fast, covering the earth’s surface.

The single most important data point for broadcasters is ascertaining the audience. Our product is “eyes and ears,” a.k.a. “attention,” and we are not alone seeking and selling it.

[Read More Guest Commentaries Here]

When it comes to quantifying and qualifying the audience, OTA falls short of the internet. Interactivity, targeted advertising, non-linear and rich media are all impracticable within the current ecosystem.

That’s not trivial. Radio really can’t compete well with delivery that tells our customers exactly who is listening and can target advertising, alerts and other content.

Radio’s traditional exclusive sweet spot had been mobile. But streaming to smartphones, cars and portable “radios” with the present-day “carrier” access networks, even without 5G, is better in most ways than OTA.

FM chips in phones were never a viable option. But patrons expect that smartphone FM radio will work in any location — basement, elevator, office — where cell phones do but OTA FM cannot reach.

Selling points
So why should radio broadcasters be interested in ATSC 3.0?

First, NextGen Broadcast — and that’s what it is — is not just TV. Because it is IP-based, it can carry anything: linear radio and any data service, album art, or whatever … along with TV.

Second, OFDM on UHF runs circles around AM or FM in terms of coverage and penetration. Critical to this, is that like the HD/OFDM part of HD FM, single-frequency networks composed of multiple transmitters can push coverage into places otherwise unreachable by any other means other than the cellular carriers.

NextGen Broadcast on UHF is beachfront spectrum. No one is lining up to re-farm MW and VHF spectrum. There will be no auctions of radio spectrum.

Moving radio to NextGen Broadcast changes the ground rules.

For my entire career, it has been clear that the Venn diagram of radio and TV has two spheres that are destined to converge. The move to IP does exactly that.

In American radio, broadcasters ordinarily own and operate their own single-service transmitter (HD2, HD3 aside) and maybe some translators and streaming servers. NextGen Broadcast is a multiplex of services, radio, TV and data.

Some NextGen pioneers plan to aggregate their spectrum to move content between transmission systems; adjusting modulation/coding to maximize coverage, reach and capacity as appropriate for the individual services.

ATSC 3.0 can do that. Radio services could have a lease or other arrangement for access to a slice of NextGen multiplexes.

Currently, an FCC license is for 6 MHz of spectrum traditionally held by one entity. In NextGen broadcast, that license typically houses multiple “broadcasters.”

While one might not have to worry about tower lights or transmitter maintenance, “radio stations” likely would not be limited to those with a license and call letters. Regulations probably need to be updated, if for no other reason than rules enforcement reaches the spectrum holder and not the occupants.

There are other regulatory opportunities. For example, being IP, emergency alerting can be done once, collectively, for the whole multiplex.

NextGen has momentum
The current DTV transmission ecosystem is shifting to ATSC 3.0, with the first wave approaching completion with about 75% of the population covered by at least one NextGen Broadcast signal. According to some estimates, 2 million 3.0-capable TV sets will be in homes by Christmas of 2022.

If you think radio has challenges, look at TV. Current DTV is stuck with an ancient inefficient codec that can’t handle what today’s TVs can display and a modulation scheme (8-VSB) that can’t handle motion or support single-frequency network boosters.

It’s hard to imagine that in a decade, OTA TV will still be ATSC 1.0 in any sustainable way. Manufacturers are heavily invested in selling NextGen Broadcast throughout the world because that sells bigger, better TVs. They just have to be contemplating better “radios” too.

So how does that get NextGen Broadcast receiver chips into cars and smartphones?

For that, we have to look at the symbiotic relationship between ATSC 3.0 and 5G.

While most of the world’s connectivity traffic is unicast, the bulky part is broadcast. While the obvious 3.0 use case is the 700-pound gorilla of live linear radio and TV, there is also the anticipated distribution of data for self-driving cars and certainly things yet undreamed.

One can speculate that as the NextGen Broadcast infrastructure expands, discounted distribution and low-cost storage will be attractive for delivering more than the obvious popular movies and podcasts.

When it comes to the intersection of technology, regulation and business, anything can happen anywhere. However, NextGen Broadcast is designed to replace the world’s aging and imperfect OTA distribution. All of it.

This isn’t an incremental improvement.

As NextGen Broadcast transmission is lighting up, what is being distributed is, with few notable early exceptions, simulcasts of existing TV and radio content. That is not a typo. Audio services, including simulcasts of legacy radio stations, are being conveyed by NextGen Broadcast on the air now.

What’s next is the consumer side of the ecosystem. Clearly the first multi-millions of NextGen reception devices will be about simply making pictures and sound.

We radio broadcasters have “asks” that we might not have thought we could dream of. Dynamic (targeted) advertising and listener intelligence will need the devices to run apps that are built in or placed on the device by broadcasters. First-run NextGen TVs do some of that. Radio should be next.

Real opportunity
In a nutshell: After 20-plus years, and millions if not billions of dollars of development by hundreds of entities, NextGen Broadcast is authorized and on the air. Whether incumbent “radio” broadcasters take advantage of its capabilities and opportunities is an individual choice.

Some will stay the course, but others will enter a converged media world that is free of the major impairments and limitations we’ve been “improving” and “revitalizing” our way out of with limited success.

The combination of near-perfect distribution and the unlimited capabilities of OTA IP is a radio content provider’s Holy Grail. It might start with NextGen Broadcast simulcasts, but as a believer in radio, I think it goes much further. While we’ve been running toward revitalization, NextGen Broadcast has just tapped us on the shoulder. This is a tipping point that might take some of us by surprise.

Someday, I’d like to listen to radio in a hotel room again.

The Nebraska Broadcasters Association has joined the Society of Broadcast Engineers’ effort to bring new technical talent to the field of broadcasting through the SBE’s Technical Professional Training Program.

The SBE created the program at the beginning of 2021 in response to concerns about the ability to fill technical positions as current engineers age out of the workforce, as well as innovations in broadcasting technologies continue.

Launched in January, the NBA plans to cover the cost of TPTP enrollment for up to 12 enrollees, each accepted on a first-come, first-served basis for 2022. It has limited enrollment to one enrollee per dues-paying station employment unit.

[Related: SBE Launches New Training Program]

Jim Timm, president and executive director of the NBA, said many broadcast engineers are retiring faster than they can be replaced.

“Recognizing that many stations have a person or two on staff with some technical aptitude,” he said, “we feel the SBE’s TPT is an ideal way to help them expand their capabilities and potentially, groom some future engineers for NBA member stations.”

The Missouri Broadcasters Association launched a similar support program in 2021. Terry Beth Harper, director of member services for the MBA, agreed that finding replacements for those who have or are getting ready to retire can be difficult.

“Someone just starting out might find the right fit in the technical environment, and this program gives them a chance to explore that world a little deeper,” she said.

SBE President Andrea Cummis, CBT, CTO, added, “The SBE continues to increase its education efforts, which includes the TPT. The Nebraska Broadcasters Association and Missouri Broadcasters Association have actively embraced the program, which will hopefully serve as models for other state associations to follow.”

[Related: Cummis Set to Take the Lead at SBE]

There have been 33 participants since the launch of the TPTP. So far, the fixed number of participants budgeted for by the SBE has not been met.

The cost of the SBE TPTP is $475. This includes a one-year SBE membership with SBE MemberPlus, a copy of SBE CertPreview, a copy of the SBE Engineering Handbook, enrollment in the SBE Mentor Program, and the SBE CBT certification exam application fee to be taken later.
