Here’s the latest pic from our “Engineers at Work” feature:

The National Association of Broadcasters and Xperi Corp. are working to test the performance of HD Radio’s MA3 mode in electric vehicles. As part of that effort, Russ Mundschenk of Xperi and Dave Kolesar of Hubbard’s WWFD(AM) took this selfie while driving around to help document the Core and Core+Enhanced coverage of the station. (Clearly, these guys are NRSC-5 RF Mask Compliant!)

The two were in a gasoline-powered control car, a Hubbard-owned 2015 Subaru Crosstrek.

WWFD is the all-digital AM station in Frederick, Md., that has been operating under experimental authority. The FCC this week opened the all-digital option to all AM stations in the United States.

Mundschenk and Kolesar also are the two most recent recipients of the Radio World Excellence in Engineering Award.

In the Oct. 14 KDKA feature the question is twice asked — including in a Page 21 photo caption — “Did engineer Donald Little invent and fabricate the world’s first transducer for turning record groove modulations into a varying voltage?”

The answer is: Decidedly not. The honor for that advance goes to Gianni Bettini, an Italian army lieutenant who made his fortune in the U.S.A but died and remains back in Italy, having patented electrical recording in 1902.

Bettini took a Berliner microphone, manufactured by Bell’s Western Electric Co. and of the type that went into all the world’s telephones for 100 years (which includes KDKA’s in 1920), pushed a needle through the center of its diaphragm and turned it into a phonograph pickup. Bell, Edison and even disc record “revolutionizer” (no pun intended) Emile Berliner missed it. Had any one of them paid attention we’d have had electrical recording two decades before Western Electric introduced it when they created motion picture sound in 1926 (or was it ’25?).

For Radio World readers it should be noted that the broadcasting business quickly adopted WECo’s 33 1/3 rpm 16-inch disc which inaugurated the quarter-century era of recorded-program dissemination on discs. Interestingly, the four networks — NBC (Red), NBC-Blue, CBS and Mutual (the least heralded yet with the most affiliated stations of all) — engaged my friend Harry Bryant’s Radio Recorders in Hollywood to create what came to be called “transcriptions” for delayed broadcast on the “coast” of shows coming in “live” from New York, Chicago, Pittsburgh and Detroit.

Nielsen PPM encoding is now built into the Optimod XPN-AM processor from Orban Labs, at no additional charge, according to the company.

Users who already have an Optimod XPN-AM can contact the company for information on a free upgrade.

Orban Labs issued a press release saying that stations that are now handling Nielsen PPM encoding via XPN-AM include KHTK in Sacramento, KSL in Salt Lake City, KKYX in San Antonio and WSB in Atlanta.

The announcement included endorsements from Bonneville’s Jason Ornellas, director of engineering for Sacramento, and Aaron Farnham, its DOE in Salt Lake City.

“We are broadcasting HD Radio AM using MDCL that gives us additional power savings [at KSL],” Farnham told Orban, highlighting cost savings of having Nielsen encoding built in. “It gives you the ability to process and then encode so you don’t damage the quality of the encoding.”

The XPN-AM Audio Processor is based upon an AM-optimized version of Orban’s MX limiter technology. Orban highlights its ability to generate greater density with lower distortion, saying this can significantly reduce power consumption for users of transmitters equipped with Modulation Dependent Carrier Level. The processor is available in AM and AM/HD Radio versions.

WMGG is the 1470 signal listed in the 96.1 FM Caliente logo.

A Florida AM radio station plans to go all-digital soon, now that the Federal Communications Commission has allowed such transitions.

WMGG is owned by NIA Broadcasting; it’s a Class B station in Egypt Lake, Fla., near Tampa, airing a directional signal via a diplexed array. It has 2.8 kW power by day and 800 watts at night, and airs on 1470 kHz.

The company also owns several other AM, FM and TV properties.

President Neal Ardman told Radio World he is in the process of ordering a Nautel HD Radio transmitter to make the change.

“It is time,” he wrote in an email, adding that he is “not worried” about losing analog listening.

WMGG has an FM translator on 101.9 MHz. Both signals are part of “96.1 FM Caliente,” the radio home of the Tampa Bay Buccaneers’ Spanish-language network.

Entercom and FanDuel will also collaborate on in-depth integrations and co-produce new formats and content. “The partnership brings together America’s #1 sportsbook with the #1 sports audio company in the United States,” the companies said in a statement.

The goal of the strategic partnership is to unite two companies in a shared mission to entertain, engage and inform sports fans around all aspects of the game, the companies said. In addition to creating a new model between a sports gaming operator and sports media platform, Entercom also called it the largest advertisement commitment made in radio industry history.

“We are focused on delivering the best sports betting experience for our audiences in markets where legalized sports betting will be pervasive,” said David Field, president and CEO of Entercom. “The marketplace is growing exponentially and FanDuel is an ideal partner to take full advantage of the influence and reach of Entercom’s robust sports platforms to deliver an even better audio sports experience to our listeners.”

FanDuel CEO Matthew King said that in the two years that it has been doing business with Entercom, it became clear to FanDuel that Entercom’s authentic connection with sports fans is one of the best ways for it to engage FanDuel customers.

“We will work together to offer sports fans access to information wherever, whenever and however they consume content, providing them with the tools to learn and win,” he said.

As widely expected and now reported, the FCC has adopted rules to allow AM radio stations in the United States to broadcast an all-digital signal using the HD Radio in-band on-channel MA3 mode.

At the same time, as a small nod to those who either object or would like FCC to consider DRM as well, the commission noted the interest in “alternative technologies,” aka DRM.

All the arguments in favor of DRM — audio quality, coverage, flexibility, extra services, lack of interference or link to one single proprietary company and the extensive proven record — were not enough for the FCC. They considered that looking at other technologies was beyond the scope of the 11-month consultation.

Some might argue that this was more about endorsing one technology rather than examining in detail what can be done to save AM proper. A fuller DRM dossier was required with laboratory and field results, and this request seems reasonable.

There is one snag though: DRM for mediumwave has been tested and documented about two decades ago. It has been recommended by ITU in 2005 and all the tests carried out all over the world are available openly and freely for anyone to see.

Moreover, 35 stations, soon to be increased to 41, in India, are on the air every single day Their coverage is about 800 million people, and this is slightly more than the one and a half station proving the advantages of MA-3.

The DRM Consortium can monitor every second of these live transmissions every day and this can be checked by FCC whenever they want.

These are facts and not more assertions by DRM proponents. A U.S. lab and real test of DRM in the country, as mentioned by the FCC, would be useful but would not change the laws of physics. With FCC support and that of North American broadcasters and broadcasting bodies this could be easily achieved.

In conclusion we feel that, for now, FCC has taken a positive step and sent a good sign about mediumwave revitalization and not only in the U.S.

We know that confrontation has never helped any technology assert itself. Cooperation and fairness have. And DRM is ready to prove its advantages using the opportunity offered by the FCC in their statement.

The DRM consortium remains ready to assist bodies in the USA keen to adopt the system that is finding success in many other countries around the world. This will allow radio on the AM bands to thrive in the digital age using an open competitive system.
