Radio World: “Who’s Got the Biggest, Meanest AM Flamethrower?”

(Source: Radio World)

More broadcasters than you might realize are helping keep the ionosphere warm (and the power companies happy)

In the May 9 issue of Radio World, I reported on a recent power upgrade at TWR’s Bonaire AM facility that brought that station close to the half-megawatt level (440 kW), allowing the station to make the claim that it is the most powerful medium-wave (MW) operation in the Western Hemisphere. After the dust settled, I thought it might be interesting to poke around a bit in the data available to see if they have a close (or even not-so-close) contender for second place for this title.

With only a few exceptions, U.S. stations have been capped at 50 kW since this power level was authorized by the Federal Radio Commission in the late 1920s. Powel Crosley Jr.’s WLW 500,000 kW 1930s “experimental” operation is one very well-known example, as it received a lot of publicity during the five years or so during it operated before being powered down. However, there was another much less well-known superpower operation during that period (it actually beat WLW to the punch by putting 400,000 Watts on the air about three years before Crosley was ready to belt out his hundreds of kilowatts).

[…]Surprisingly, there is one U.S. AM station that has the necessary paperwork and equipment to operate at 100 kW full-time. However, it’s not listed in the FCC’s AM database. I’m referring to the VOA’s “Radio Martí” in Marathon, Fla. which operates on 1080 kHz.

The VOA station (it sports no call sign) appears to be the only operation in its class in the U.S. and Canada, but it if you cross the border into Mexico, you’ll find “muchas estaciones de radio” that emit lots more than a puny 50,000 “vatios.”[…]

AFRTS: Thousands of hours of Roger Carroll shows now online

Beginning in the early 1940s and for more than 50 years, the U.S. armed services produced long-form radio programs on vinyl disc to broadcast to troops overseas.

These were usually recorded by the top voice talents in Los Angeles and were heard over the American Forces Radio TV Service. Many of the same talent later created other shows specifically to aid the military with recruitment. The latter programs were then distributed to American radio stations for free on-air use.

Until recently, this trove of historical programming had been M.I.A., but now thousands of hours are available for online streaming, thanks to Army veteran Thom Whetston, who served in Panama and Korea.

“For years, AFRTS recorded many hours a week of personality-oriented music shows, and these were sent all over the world,” Whetston said. “The guys that hosted them got complimentary copies, and luckily one air talent in particular, Roger Carroll, saved most of his albums in his garage. For the last 10 years I had been writing a blog about AFRTS, and about a year ago, with Roger’s help, I began building a website where people can hear these shows again.”[…]

DRM feeds RNZ Pacific relays

RANGITAIKI, New Zealand — Radio New Zealand Pacific, the official international arm of Radio New Zealand, is using Digital Radio Mondiale digital radio transmission/reception equipment to feed studio-quality audio to some of its 20 relay stations in the Pacific Ocean region. The others use satellite feeds or web downloads.

The locations being served by DRM include the Cook Islands, where RNZ Pacific’s programs are rebroadcast locally in analog mode by Aitutaki 88FM, the islands’ only broadcaster. RNZ Pacific also serves Tonga, Samoa, and the Solomon Islands using DRM; among others. Previously, RNZ Pacific had fed its relays using analog AM shortwave radio, with that transmission mode’s limited audio range and interference issues.

“When DRM became available to us in 2005, we saw it as a great opportunity to provide high quality audio to Pacific radio stations that relayed our news broadcasts from our AM transmitter,” said RNZ Pacific’s Technical Manager Adrian Sainsbury. “As a platform to deliver good quality audio to remote island FM stations, it has been a great success.”[…]

As the article points out, RNZ has been using DRM as a feed for quite a few years. I think this is a brilliant use of the technology. Of course, those of us in the rest of the world can snag RNZ DRM broadcasts as well.

Pirate Radio Bill Formally Introduced

Bipartisan legislation designed to thwart and penalize radio pirates and supporters

BY SUSAN ASHWORTH, MAY 9, 2018

Another legislative step has been taken in the effort to fight illegal pirate radio operations.

On May 8, Rep. Leonard Lance (R-NJ) and Rep. Paul Tonko (D-NY) formally introduced a bill to Congress designed to thwart and penalize illegal radio operations.

Known as the ‘‘Preventing Illegal Radio Abuse Through Enforcement Act,” the PIRATE Act will increase the ability of the Federal Communications Commission to crack down on pirate activity by increasing fines, streamlining enforcement and placing liability those who facilitate illegal radio broadcasts.

“It is time to take these pirates off the air by hiking the penalties and working with the Federal Communications Commission on enforcement,” Lance said in a statement. Chairman Pai and Commissioner O’Rielly have been able partners in making sure these broadcasts are stopped. This bill will give the FCC even more tools to take down these illegal broadcasts.”

As a commissioner who has long been searching for more Congressional authority to address pirate radio operations, FCC Commissioner Michael O’Rielly commended the effort after the news was announced.

“This bill rightfully increases the penalties, requires regular enforcement sweeps, and augments the tools available to the commission, which are woefully inadequate and outdated, to deal with illegal pirate broadcasters,” O’Rielly said in a statement.[…]

Blackloud SounDot AF1 earphones offer FM reception for iPhones

Many thanks to SWLing Post contributor, Richard Langley, who shares this article from Radio World. Here’s an excerpt:

Headsets Deliver FM to Mobile Devices, No Chip or Internet Required

[The BLACKLOUD SOUNDOT AF1] headsets are nothing like the ones you might remember from your first Sony Walkman. According to information provided by Blackloud, SounDots feature patented psychoacoustic technology, a six-band customizable graphic equalizer, 3D stereo effect, dual dynamic driver design, inline microphone, and a control box with a volume up (+), volume down (–) and multifunction (pause/play) button. This multifunction button enables many actions depending on the app that is running, including: answer/hang up a phone/video call, start/stop recording or playback using most any audio/video/camera app, enable/disable/seek up/down the FM tuner, and lastly, activate Siri or Google Assistant.[…]

Richard notes that we’ve posted articles in the past focusing on the fact that iPhones (and a number of Android phone models) do not have or allow user access to a built-in FM reception chip.

Richard sees the new Blackloud SounDot AF1 earphones as an elegant work-around and has pre-ordered a set. If these earphones live up to their specs, they should sound fantastic.

Richard, I hope you’ll post a review after you put them into service! Thanks for the tip!
