GeoBroadcast Proposal Likely to Get a Look at FCC
It looks like the efforts of GeoBroadcast Solutions at the FCC are producing some movement.
According to Commissioner Geoffrey Starks, Chairman Ajit Pai has circulated a draft notice of proposed rulemaking to revise the FM booster rules to allow geo-targeting of content via FM booster stations.
Starks is emphasizing the potential benefit to small, women and minority broadcasters. He put out a statement this week saying the proposal would allow the practice on a limited basis.
“The use of geo-targeted content could provide a way for minority-owned stations to better serve their communities by offering hyper-localized content including alternative language news, weather, emergency alerts and advertising periodically during the broadcast day,” Starks wrote.
“For small businesses, this option could enable them to more cost-effectively advertise to a targeted audience while enabling minority-owned FM stations to increase advertising revenue.”

Starks noted the support of this idea from 21 civil rights advocacy organizations including MMTC, the National Urban League, the Hispanic Federation, the National Association of Black Owned Broadcasters and the National Asian American Coalition.
“I am pleased to support this innovative proposal, which could offer a potential lifeline to small, women and minority broadcasters that are struggling to retain their listening audiences and earn advertising revenue at a time when consumers have multiple options for access to information, entertainment, education, and civic engagement.”
Some broadcasters have told the FCC that if it were to allow this practice, it should also allow translators to original content.

Radio Pioneers: Edwin Howard Armstrong and William Lear
The author is with the National Inventors Hall of Fame.
Although today’s listening experience tends to be dominated by streaming services, radio remains a critical foundation for disseminating sound. Radio has evolved over the past century to expand its reach and its offerings. The portable transistor radio may exist more as a relic than as an everyday item, but in its place are options like satellite radio and smartphone-enabled apps that will still play your favorite stations.
Historically, there was a major boom in demand for radio access following World War I and then during and after World War II. In addition to newspapers, radio played a leading role as a source of trusted information for the public. As radios became more common among households, more family-oriented programming also developed and became a popular form of entertainment.

In the 1950s, radio stations were competing with the emergence of television and began expanding their musical broadcasts to include varieties like rock ‘n’ roll. Disc jockeys, or DJs, became a go-to source for many young people, leading to the rise of new music and genres that reached listeners everywhere.
While many of us are accustomed to radio as a common fixture, it took the creativity of people like National Inventors Hall of Fame (NIHF) Inductees Edwin Howard Armstrong and William Lear to help us reach this point.
In celebration of the 100th anniversary of the invention of the radio this November, we invite you to read more about the lives of these remarkable innovators.
Edwin Howard Armstrong — FM Radio
Click image to enlarge.From a young age, Armstrong often tinkered with inventions and quickly developed a strong interest in studying circuits. By his third year of college at Columbia University, he had invented the regenerative circuit. During World War I, Armstrong served in the U.S. Army Signal Corps laboratories in Paris, where he invented the superheterodyne circuit to amplify weak, high-frequency electromagnetic waves.
By 1933, Armstrong had developed a solution to the problem of eliminating radio static. His new system varied radio wave frequency over a wide band of frequency rather than a narrow band. This wide-band frequency modulation (FM) improved radio signals and allowed for newly static-free broadcasting.
William Lear — Car Radio

Though he only completed formal education until the eighth grade, Lear went on to join the U.S. Navy at age 16, where he would learn radio electronics. Following World War I, he used his training to launch his own company that sold and repaired radios. With his company he developed the first practical automobile radio, which included a non-battery home radio receiver with a built-in speaker.
In 1924, he sold the rights to the radio so that it could be produced on a larger scale. Galvin Manufacturing Corp., later called Motorola Inc., purchased the rights and the car radio became the company’s first major product. Lear continued to invent throughout his life, most notably founding Learjet, which became the leading supplier of corporate jets in the 1960s.
Thanks to the radio innovations developed by Armstrong and Lear, people everywhere have gained better access to information and entertainment.

No Luck for DRM in the AM Digital Order
Digital Radio Mondiale was hoping that the Federal Communications Commission would consider allowing its technology as an all-digital option for AM stations in the United States, along with HD Radio. But the FCC disappointed it.
In its order allowing AM stations the option to turn off their analog and broadcast the MA-3 mode of HD Radio, the commission noted the interest in “alternative technologies.”
“Many commenters agree that all-digital AM broadcasting should be allowed but object to HD Radio as the sole authorized transmission technology,” it wrote.
“Specifically, commenters urge us to consider the Digital Radio Mondiale all-digital transmission technology on the grounds that it: (1) offers equal or better sound quality to HD Radio at lower bitrates; (2) can transmit metadata as well as emergency alerts, multicast subchannels, and a data channel; (3) is energy- and spectrum-efficient; (4) uses a superior audio codec; (5) is not susceptible to interference; (6) is not owned or controlled by a single company; and (7) has been used successfully in other countries and is the approved technology for shortwave broadcasting in the United States.”
But the FCC said the request was “beyond the scope of this proceeding.”
It said it needed to move expeditiously on this all-digital proposal; and that if parties believe that it should re-evaluate HD Radio and consider alternative technologies, “we would need to evaluate a fully developed proposal including data such as laboratory and field testing, similar to the petition for rulemaking that formed the basis of this proceeding.”
In the absence of data regarding DRM performance in the U.S. AM band, the FCC said it cannot evaluate its merits based just on assertions of its proponents.
“In the present proceeding, we authorize all-digital HD Radio operations now for the same reasons the commission authorized hybrid HD Radio operations in 2002: it is currently the only ‘feasible, near-term digital technology option’ before us and the adoption will ‘provide regulatory clarity and … compress the timeframe for finalizing the rules and policies that will affect the ultimate success of this service.”
However the commission said this does not foreclose future consideration of alternative transmission technologies.

User Report: MPR/APM Build Links With Burk
The author is chief engineer at Minnesota Public Radio.
Minnesota Public Radio and American Public Media are headquartered in downtown St. Paul, Minn. within sight of the state capitol.
It operates 49 public radio stations and 42 translators serving listeners in eight states. MPR delivers three services for broadcast via satellite. The APM program portfolio reaches nearly 20 million listeners each week. Notable programs delivered live include BBC World service, “C24” and “Marketplace.”
During my 10 years with the company I have seen the Gentner/Burk GSC system migrated entirely to Burk ARC Plus Touch, ARC Plus SL and ARC Solo at 37 sites.
Flying on AutoPilot
The decision to continue with Burk for a complete remote control system update was not automatic but made sense. The GSC-to-ARC transition was aided by using the Plus-X GSC Adapter which made transition at many of our sites plug-and-play.
While most of our sites are transmitting facilities, we also have a Burk system installed at our Network Operation Center in St. Paul, which monitors codecs, satellite uplink and downlink, building temperatures and UPS status, and at the Public Radio Satellite Systems (PRSS) NOC in Washington, where our live streamed network contribution is nominally uplinked.
Our St. Paul NOC uses AutoPilot to watch over sites on multiple computers. This gives our NOC operator a machine to use while a member of the radio network team is on another machine remotely. Sites I need to see regularly are best viewed with AutoPilot from my PC. ARC units reliably report to multiple AutoPilot instances. Additionally, the Warp Engine Polling feature minimizes processor load and IP bandwidth on computers running AutoPilot. I am aware of the smartphone options that Burk has but so far have not added that to my device. While we have the relative luxury of a full-time NOC operator, I will probably avoid that.
One of the AutoPilot custom views used at the American Public Media NOC in St. Paul, providing more than 175 status and metering indications from seven sites.Transmitter sites require a primary and backup remote control connection, so most sites still have a POTS line to provide a modem connection in the event of an IP failure. We have recently seen situations where the POTS line will not work reliably with the modem and there are a couple of sites that use the Burk RSI voice interface for backup. Burk works well at sites that use wireless internet as well.
I am a big fan of Custom Views in AutoPilot. One red spot on a screen will stand out even among hundreds of statuses and meters. I have created small custom views for specific purposes, like switching between two transmitters sites or keeping a close eye on equipment experiencing issues.
We are getting more versed at employing SNMP, which is taking over transmitter M and C. Our GatesAir FAX transmitters and Intraplex IP Link codecs get along well with Burk SNMP Plus. Our XDS/ATX-Networks satellite receivers display lock status and Eb/No using SNMP on multiple AutoPilot Custom Views.
In conclusion I can say we are pleased with Burk Technology products and are consistently imagining new ways to use this system.
