Pathfinder panels and logic flows at WAMU.

 

The author is assistant director of integrated broadcast systems for WAMU 88.5.

WAMU is an NPR public news/talk station that services the greater Washington, D.C. metropolitan area.

I came here a little over three and a half years ago from an all-Axia plant in Atlanta. When I arrived, they already had Telos Alliance gear and legacy Pathfinder, which made my transition smooth.

Over time, as I settled into the organization and assessed its workflows, we began to look at its Pathfinder system, which was a bit out of date and needed some love. We put together a grand plan to build a whole new Axia network with Pathfinder Core PRO to freshen everything up, clean everything out and get all the systems nice and neat.

Just as we were about to begin our switchover and start making changes — in fact, only about a week before — the pandemic shutdowns began across the country. This, of course, blew all of our plans out of the water.

Ambitious remote operations

Our station decided very early on to transition to a full remote workflow, and having Pathfinder Core was a big part of reacting accordingly.

We run a national talk show for two hours every day of the week and a local talk show for an hour after that. During these shows, we run through codecs quickly, and in the studio, we had a dedicated person to get people on, connected and checked. We realized that our remote codec position needed some custom help.

For that we turned to Pathfinder Core to build what are called “panels.” A panel is a graphical and functional representation of equipment, signal flows and other functions such as monitoring and internal communication.

We built a panel that allows our codec manager to work remotely and test all 30 to 40 codecs we’ve got, doing line checks and making sure everyone is good to go before show time, and to troubleshoot issues. This was a large panel that I built, and it was a massive help to our operations.

WAMU built a panel allowing codec manager to work remotely and test 30 to 40 codecs; this shows a portion of the screen.

We also built panels for our producers to remotely produce their shows, giving them a real-time feed of the show over a telephone hybrid and the ability to talk to the host, engineer or codec manager as they need to. The fact that Pathfinder Core allows you to do this with web panels makes distributing them to a ton of producers very easy.

We had 35 people “pitching” during our week of remote fundraising, and web panels allowed our pitch producers to speak to the pitchers to coordinate and cue their segments quickly. We turned our panels pages into a series of short links that make onboarding easier than before.

New way of thinking

The most powerful new feature in Pathfinder Core PRO is the relay combiner in Logic Flow events.

With the codec panel I built, we needed to update Logic Flows with new codec sources and destinations actively. When the codec manager opens a panel, they can choose their current codec, which gets written to the “Talk” button’s logic.

I could have accomplished this flow in the old system but with many more steps. When I started using the new system, it took me a little while to get used to the new way of thinking about Logic Flows, but once I got up and running, I was amazed at how much I enjoy using the system.

Right now, we are running a hybrid system of legacy Pathfinder and Pathfinder Core. Any new panels we need are built on Pathfinder Core, while the legacy system is still handling all of our studio switching and air chain events. We are getting close to the point where we will begin migrating over the rest of the systems, and I’m looking forward to having it all up to date.

In this document, the Federal Communications Commission (Commission) announces that the Office of Management and Budget (OMB) has approved, for a period of three years, the information collection requirements associated with the Second Report and Order of the Commission's Rules Regarding Public Notice of the Filing of Applications; the Report and Order in Low Power FM Radio Service Technical Rules; the Report and Order in Reexamination of the Comparative Standards and Procedures for Licensing of Noncommercial Educational Broadcast Stations and Low Power FM Stations. This document is consistent with the Report and Orders, which stated that the Commission would publish a document in the Federal Register announcing OMB approval and the effective date of the information collection requirements.

The Commission has before it a petition for rulemaking filed by Sander Operating Co. III LLC (Sander), licensee of KGW, requesting the substitution of channel 26 for channel 8 at Portland in the DTV Table of Allotments. The Commission instituted a freeze on the acceptance of rulemaking petitions by full power television stations requesting channel substitutions in May 2011, and Sander asks that the Commission waive the freeze to permit KGW to change from a VHF to a UHF channel to better serve its over-the-air viewers. Sander states that the Commission has recognized that VHF channels have certain propagation characteristics which may cause reception issues for some viewers. While Sander acknowledges that VHF reception issues are not universal, it states that since the 2009 digital transition, when it began operating exclusively on digital channel 8, KGW has received a steady stream of complaints from viewers unable to receive the station's over-the-air signal, despite being able to receive signals from other local stations. Sander believes that waiver of the channel substitution freeze would serve the public interest.

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.”

[Read what the chief technology officer of GBS has said about the idea in his commentary “ZoneCasting Would Level the Playing Field for Radio.”]

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.

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

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 “Bill” Lear had a prolific invention career. 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.

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.
