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.
[…]“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.”[…]

New DX Program
People have asked us to air a DX program for many years. KTWR had
done this a few decades ago, but we had no one to produce a new
program. Now, one of our listeners, Arun Kumar Narasimham has begun
production of the “Dxers Diary”. The first airing will be on 25
October 2020 in our 1026-1057UTC English DRM broadcast to India on
13800kHz. We are glad that Arun has stepped in to fill this
longstanding gap in our programming. We hope you enjoy it and
continue to enjoy the DX hobby.
Thank you for the tip, Ed, and we’ll look forward to any updates you might have.
A new era begins for Brazilian radio broadcasting with the arrival and installation of a first shortwave digital radio DRM transmitter developed and manufactured in the city of Porto Alegre by BT Transmitters. The transmitter will be sited at the public broadcaster (EBC) Rodeador Park, near the capital Brasilia, to be connected to one of the huge HF antennas of EBC (National Amazon Radio is transmitted from there).
The equipment (a transmitter of 2.5 kW) will be tested on an experimental and scientific basis with the help of the University of Brasilia (UnB) and the Ministry of Science, Technology and Innovation.
The National Radio of the Amazon broadcasts from Brasilia especially to the Northern, Amazonian region of Brazil. The signal will be also available in the neighbouring countries to the north of Brazil. This is primarily a domestic shortwave digital project aimed at the Amazon where about 7 million riverside and indigenous people live. They are far from any other means of communication as there is no mobile phone or internet coverage.
Rafael Diniz, the Chair of the DRM Brazilian Platform, thinks that: “Shortwave digital radio (DRM) for the Amazon region will ensure a new level of communication and information as Nacional’s programming is both popular and educational. It brings audio and much more at low energy cost to whole communities there. With the adoption of digital radio, one of the major problems, that of poor sound quality affecting at times shortwave, will end. Listeners will be able to enjoy DRM broadcasts in short wave with a quality similar to that of a local FM station together with textual and visual multimedia content.”
“This is a huge step forward, says Ruxandra Obreja, DRM Consortium Chair, “not just for Brazil but for the whole of Latin America. When everything else fails or does not exist, DRM will provide information, education, emergency warning and entertainment at reduced energy costs.”
As a side note, I do hope the DRM Consortium or the University of Brasilia and the Ministry of Science, Technology and Innovation somehow make DRM receivers available to the “7 million riverside and indigenous people” they hope will eventually benefit from their broadcasts. At this point, however, this sounds more like a university experiment similar to those conducted at the Budapest University of Technology in Hungary.

Radio Waves: Stories Making Waves in the World of Radio
Because I keep my ear to the waves, as well as receive many tips from others who do the same, I find myself privy to radio-related stories that might interest SWLing Post readers. To that end: Welcome to the SWLing Post’sRadio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!
Many thanks to SWLing Post contributors Ed, Paul, Bennett Kobb, and Kanwar Sandhu for the following tips:
Here is the story by Bennett Kobb:
As previously reported here at DRMNA.info, the New York company Turms Tech LLC has applied to the FCC for a license for International Broadcast Station WIPE in New Jersey. The license would cover a station already built under a FCC Construction Permit, and would allow it to begin regular operations.
The FCC announced on August 13, 2020 that this license application was accepted for filing, a routine stage at which the FCC examines the application, and might even visit the station, and if everything is in order it will be licensed.
We’re not sure everything is in order. The application for Construction Permit placed the transmitter site at N 40° 57′ 40.38″, W 73° 55′ 23.97″, the broadcast and communications center surrounding the famous Armstrong Tower at Alpine NJ. Its Application for License, however, specifies N 40° 51′ 40″, W 73° 55′ 23″. (Hat tip to Alex P for noting this discrepancy. More about him below.)
While the substitution of 51 for 57 in the coordinates might seem a simple typo, the FCC typically has no sense of humor about coordinate errors. Commission examiners may wonder why a station intended for a historic radio-TV facility ended up among some Manhattan apartments.
The deeper question with WIPE and another, apparently similar station WPBC, is what these stations are really for and what that means for the FCC Rules. WIPE was extremely vague about its program plans, but told the FCC that it will transmit data obtained from third parties using Digital Radio Mondiale. Putting that tidbit together with exposures in a series of public articles in the media and tech blogs, it would seem that audio programming will not be the central mission of this peculiarly named station, whose principal is a financial executive and forestry entrepreneur without any broadcast experience we could find.
We suspect instead that the WIPE data stream will be used not for broadcasting to the public — the only function permitted to International Broadcast Stations under FCC Rules — but instead will be used for private communication with foreign exchanges for high-speed trading.[…]

After bombarding coastal areas of southern Louisiana with wind gusts up to 130 mph and a storm surge over nine feet as a hurricane, Laura swept north while also spreading over Arkansas Thursday. Laura weakened to a tropical storm early Thursday afternoon, with winds at 70 mph, according to the National Hurricane Center. Laura is predicted to move through the Tennessee Valley and the Mid-Atlantic today into tomorrow.
Power outages from the storms totaled over 900,000 as of Thursday afternoon, according to PowerOutageUS. The site collects data from utilities nationwide. The bulk of the outages were in Louisiana and Texas, according to ABC News. Mississippi reportedly had over 9,400 customers without power as of Thursday morning, reported the Clarion Ledger.
Louisiana and Texas had the most cell site outages as of Thursday mid-day, according to the FCC’s Disaster Information Reporting System. Of the 4,650 cell sites served in Louisiana, 380 were not working. Over 200 of the site outages were due to a lack of power, 141 had a transport issue and 16 were damaged.
Calcasieu and Cameron counties were hit especially hard. 140 sites (75 percent) were not working in Calcasieu County and 20 (69 percent) were out in Cameron County.
Of the 17,621 cell sites served in Texas, 113 were non-operational.
Jefferson County was the hardest hit, with 39 (15.8 percent) out of 247 sites not working. Just over 45 of the non-working sites were out due to a lack of power, 41 for transport reasons and 20 were damaged, according to DIRS.
Cable and wireline companies reported 192,915 subscribers out of service in the affected areas; this may include the loss of telephone, television, and/or Internet services.
Three television stations, five FMs and one AM reported they were off-air.[…]
I’ve heard ham radio is dying since as far back as I can remember. It’s one of those common sayings you always hear. Like, “get off my lawn,” and “kids these days.” But is it true? Is there any evidence to support this? Let’s take a closer look.
Data from the ARRL shows that ham radio licensees are increasing. When you look at the chart above, you see two significant markers that are likely driving this growth.
The removal of the code requirement by the FCC.
The economic collapse of 2008.
The Morse code requirement was always an intimidating part of obtaining your General FCC license. Learning Morse code is like learning a second language. It takes time and effort to learn, and that’s not a bad thing. However, it doesn’t change that it scared many people away from the hobby. When the FCC removed this requirement in 2007, I believe it opened the door for many who spent years on the fence. Then you have the economic downturn of 2008. What does that have to do with ham radio? A lot.
After the economic downturn, the United States watched as survivalism, now commonly calling “prepping,” entered mainstream culture. People were worried as the country was involved in multiple wars and our economy was on the brink of collapse. Citizens stocked up on food storage, water, firearms, and…communications equipment. As our country spiraled into more turmoil ham radio licenses steadily increased to more than 750,000 by the end of 2019.[…]
Many thanks to SWLing Post contributor, Bennett Kobb, who shares an FCC Informal Objection he drafted and filed together with Kim Elliott and Christopher Rumbaugh.
There’s a plan in the works to build a new international shortwave radio station in Illinois, one that would use the Digital Radio Mondiale modulation system. But now several prominent members of the U.S. shortwave community are asking the Federal Communications Commission to take a closer look first.
Parable Broadcasting Co. in April asked the FCC to allow it to build the station in Batavia, Ill., west of Chicago, using the call sign WPBC. It wants to offer “broadcasting and data services.”
Specifically, Parable wrote that the station would “serve the areas of Europe that may be authorized by the commission. The planned broadcast content includes religious and educational programming, as well as data content provided by third parties.” It added that it wants to “take advantage of the recent push by the National Association of Shortwave Broadcasters to develop and provide content for the growing DRM market.”
Now three individuals, collectively called the High-Frequency Parties, filed an informal objection. It’s that wording about data content that concerns them.
Bennett Z. Kobb, Kim Andrew Elliott and Christopher D. Rumbaugh said international broadcast stations in the U.S. are intended “to be received directly by the general public in foreign countries.”
Now they told the FCC that it is impossible to tell from the Parable application whether all of the data services and data provided by third parties will qualify. [Continue reading at Radio World…]
Bennett clarified with me:
The [FCC] rules require these [broadcasters] to be 100% broadcast stations, not a cover for some other kind of service.
Because there is no established radio service for international shortwave trading, some have used the workaround of calling them “experiments”. Quite a few such “experimental” stations have been licensed, some at rather high power levels.
But legally, the Experimental Radio Service is supposed to be for temporary scientific purposes, not ongoing for-profit operations. We don’t know what those stations are really up to because the FCC has kept the details secret. All we know is some technical data such as callsigns, frequencies, QTH.
Instead of experimental stations, others wanting to get into the data business — including the Turms Tech station in New Jersey, and this Parable station in Batavia IL — seem to be using the work-around of the International Broadcast service. That is, proposing an audio programming station that uses the DRM data channel for trading messages.
We are not in the 1970s or 80s. There’s not enough money today in broadcasting audio to other countries, to justify the millions spent on real estate, engineering, antennas and transmitter plant. Most SW broadcasting around the world is not commercial. So it is very peculiar for new entrants to drop major bucks in this field.
The new guys are probably not getting in to spread the gospel. That is a surface paint. There are already several U.S. HF stations with religious content, as you know, including WTWW, WWCR, WRMI, WRNO, WINB, WWRB, WHRI, WBCQ, WJHR etc. and most would welcome new customers for airtime.
No need to construct new stations.
So what is this new station really? Get it out in the open and ask them how they intend to comply with the existing rules. If they are in the business of carrying secure messages for traders, that does not qualify and will need some special FCC action to allow it. Let the public see the reasoning.
The rules that exist are very old. We think FCC needs to do a top-to-bottom review of the HF broadcast rules and scrap a lot of it. FCC should permit stations to be built for U.S. domestic audiences, and they should reduce the minimum AM power (50 kW) to lower this barrier to
entry.
And they should perhaps consider how data communications could be formally authorized. Maybe it wouldn’t be just a broadcast service any more, it could be a HF Communications Service with the old restrictions on languages and advertising discarded and more opportunities for people to try out creative ideas.
So we’re pressing the issue that this needs to be examined. Thanks for reading.
Thank you for sharing this, Bennett! We hope your filing gets its due attention. I also agree on one of your final points, that the FCC lower its 50 kw AM power requirement of a shortwave station as it places a huge barrier in front of would-be shortwave broadcasters.

Radio Marti began Digital Radio Mondiale (DRM) shortwave transmissions on Feb. 4. Part of the U.S. Agency for Global Media (USAGM), Radio Marti broadcasts news and other programs to Cuba. The DRM shortwave transmissions are from USAGM’s Greenville, North Carolina, site.
USAGM has transmitted in DRM before. There were some transmissions from Briech, Morocco, in the early 2000s. Greenville tested DRM in 2009 in partnership with what was then known as HCJB Global Technology. So why are they back now after an absence of over a decade?
“We want to experiment a bit with different modes and services available on DRM. We also want to help push the development of low-cost receivers and the best way to do that is to put some transmissions on the air, explains Gerhard Straub, director of USAGM’s Broadcast Technologies Division.[…]
Amateur radio enthusiasts are pushing for the former site of Radio Australia in Shepparton North to be upgraded and retained as a national museum of radio broadcast history.
Members of the Shepparton and District Amateur Radio Club and The Vintage Radio Club of North East Victoria are due to present a 25-page proposal to an anonymous consortium of buyers said to be interested in acquiring a 258ha block of land along Verney Rd.
The block includes two buildings and several large broadcast towers on the former site of Radio Australia. The site is currently owned by BAI Communications.
The Shepparton club’s assistant secretary, Geoff Angus, said the proposal would be presented to Greater Shepparton City Council for forwarding to the consortium.[…]
APRS usage seen on the History Channel “Secret of Skinwalker Ranch”
Zack Schindler writes:
I have been watching a show about paranormal activity on the History Channel called The Secret of Skinwalker Ranch. In the episode this week they hired a professor to do a balloon launch with some RF sensors. In this episode they also showed the APRS.FI webpage and I was able to read his callsign from an APRS tracker, KM4MRH.
The professor used an APRS tracking device. On the right side of the page link below you can click on Other SSID’s to see other balloon launches he has done. Normally when there is a balloon launch you can see the data from it going up and down. This page shows the Skinwalker balloon launch data transposed over a map. https://aprs.fi/#!call=a%2FKM4MRH-3&timerange=3600&tail=3600
Sadly they are using these for measuring RF fields rather than these.
Terrestrial music stations have a major cultural opportunity right now, but employees say a muddied strategy is standing in the way
Radio personality Kevin Ryder was “baffled” by KROQ’s “cold, heartless attitude” when he and his morning-show team were fired at the end of March. The station has long been an alternative/rock staple in Los Angeles, the second-largest market in the country, and Ryder had been on the air for more than 30 years.
“The new people in charge now weren’t here for the building of the world-famous KROQ,” Ryder, one-half of the popular Kevin & Bean Show, said on air when the station let him go, live one final time. “I don’t think it means anything to them. It’s a numbers business, and there’s no family aspect to it anymore. It’s only numbers, but this place was built without numbers. It was musicians, artists, and the special relationship between music, the station, and our fans.”
AM/FM radio provides localized, round-the-clock information and entertainment via friendly neighborhood voices — so in theory, it’s the perfect platform in a global crisis that forces hundreds of millions of people to stay home. But Ryder is one of many in the radio community — including on-air hosts, music directors, program directors — who have been shocked by sudden job losses in recent weeks as COVID-19 has spread across the U.S., and news out of the industry has been one bad thing after another. Why is terrestrial radio missing the opportunity here — and how should it be fighting to get back on top?[…]
