FCC Declines Request to Extend Comment Period on Shortwave Modernization Petition

A request by the Shortwave Modernization Coalition (SMC) for the FCC to amend its rules to allow fixed, long-distance, non-voice communications above 2 MHz and below 25 MHz has drawn a lot of interest, with 800 comments from observers being filed in the last 30 days. The proposal has drawn concerns from advocates for amateur radio.

However, the FCC decided not to extend the comment filing docket deadline, even after several groups requested it do so. Comments for RM-11953 were due July 31. Reply comments are welcome until Aug. 15. The proposal has drawn concerns from advocates for amateur radio.

The FCC’s Office of Managing Director in June asked for comments on the SMC proposal. It seeks to use multiple bands within the high frequency 2-25 MHz range for the transmission of time-sensitive data from fixed stations. The proposal would prohibit voice transmission and mobile operations. While the proposal excludes amateur bands, high power operations on immediately adjacent spectrum allocated to the Amateur Radio Service are being proposed. [Continue reading…]

Ham Radio Enthusiasts vs. High-Frequency Traders: A Battle for the Airwaves (Wall Street Journal)

Ham radio operators are sounding the alarm over the latest threat to their beloved hobby—and this time, it is coming from Wall Street.

A group of high-frequency trading firms are asking the Federal Communications Commission to open shortwave frequencies to greater commercial use, so they can use radio to zip financial data around the world in milliseconds.

Prominent members of the amateur-radio community say interference from traders’ broadcasts could ruin their hobby, which often involves tuning in to weak radio signals so they can chat with fellow hams in faraway places. Hundreds of hams have filed letters with the FCC opposing the traders’ proposal, and some have railed against the plan in YouTube videos.
Brock Fansler is among those speaking out. A 40-year-old Los Angeles resident with shoulder-length hair, he likes using his radio to send digital data about weather conditions to other hams.

He complains that the traders are looking to transmit with up to 20,000 watts of power, whereas amateurs are capped at 1,500 watts, and many use off-the-shelf radios with 100 watts.
“They’re asking for an insane amount of power,” Fansler said. “It’s like having neighbors move in with a drum set and guitar. This is going to be blasted all over the planet, with how much wattage they’re going to put behind it.”

The group behind the proposal, called the Shortwave Modernization Coalition, says such fears are overblown. The coalition—whose members include such trading giants as Jump Trading Group, DRW Holdings and Virtu Financial —says it has already been using shortwave for several years and there haven’t been any verified complaints of interference.

“Interstellar shout” reestablishes contact with Voyager 2 (New Atlas)

In a dramatic bit of improvisation, NASA’ Jet Propulsion Laboratory (JPL) in Pasadena, California, has managed to reestablish communications with the Voyager 2 spacecraft 12.3 billion miles (19.9 billion km) from Earth after losing contact on July 21.

On August 4, 2023, NASA engineers managed to make contact with the Voyager 2 robotic probe even though previous estimates were that this would not be possible until October 15. Contact was lost on July 21 after a series of commands sent included an error that caused the spacecraft’s antenna to point about two degrees away from Earth – a small shift that still managed to prevent the craft from maintaining radio contact.

[…]Since Voyager 2’s 20-W radio signal from the edge of the solar system is 1,000 times weaker than that of a conventional FM transmitter and can still be picked up by the DSN while off beam, the engineers reasoned that it might be possible to send a much more powerful signal from the DSN that Voyager could not ignore.

This “interstellar shout” was easy enough to set up, but putting it into practice took some patience because a one-way radio signal to Voyager 2 takes 18.5 hours to reach its destination and another 18.5 hours for a reply. That is a very nerve-wracking 37 hours.

Fortunately, on August 2, 2023 at 12:29 am EDT, Voyager 2 began returning science and telemetry data. [Continue reading…]

Communications Minister Michelle Rowland celebrates 100 years of Australian radio (RadioInfo)

Communications Minister Michelle Rowland acknowledged the commercial radio industry’s upcoming 100th birthday with a speech at Parliament House recalling the launch of 2WS in Seven Hills and the continued advocacy and up to date information that radio provides its communities.

Rowland spoke of her childhood growing up in Western Sydney saying:

“I’ll never forget the day that 2WS officially launched in Leabons Lane in Seven Hills. It was the first time that we felt recognised as a community by the media. Here were local voices telling the stories that mattered to us. We were being given at a platform at a time when Western Sydney stories weren’t always reflected in the news of the day coming from the CBD.

And now look how far our humble 2WS has come!”

Ham radio operators practise for the next emergency (Mountain View Today)

RED DEER COUNTY — The world became a little smaller late last month as the Central Alberta Amateur Radio Club (CAARC) held its annual Field Day at the Hillcrest Community Hall, at the corner of Township Road 342 and Range Road 22.

From June 24 at noon to June 25 at noon, members of the club competed to make as many contacts as they could on a wide variety of radio frequencies.

The goal was to do so without using regular power – utilizing portable generators or solar power instead.

When the Albertan was there, contacts had been made as far east as Finland and as far south as Arizona.

A forest of antennas of differing sizes and heights was set up and club members did their communicating in a nearby shelter.

The idea of the challenge, held worldwide, was to prove the operators’ ability to communicate to others without relying on traditional power in case of an emergency. [Continue reading…]

“Market Makers” Want to Expand Their Use of Shortwave (Radio World)

The FCC seeks comments on a proposal to use HF spectrum for financial data

The FCC is taking public comment on a proposal to revise the rules governing the frequencies above 2 MHz and below 25 MHz.

The Shortwave Modernization Coalition thinks the 2-25 MHz band is underused and wants to use it for the long-distance transmission of time-sensitive data from fixed stations. The users would be companies working with certain kinds of financial transactions; the proposal would prohibit voice transmission and mobile operations.

The firms in the coalition are “market makers and liquidity providers” for exchange-traded financial instruments.

This high-frequency trading industry has in fact been using shortwave links for several years to send trading data between U.S. and foreign exchanges, but it has done so under experimental authorizations. [Continue reading…]

Many thanks to Bill Pietschman who notes that the book “QTC: I Have a Message for You” has now been published on Archive.org for all to read and download free of charge. Bill writes:

I knew Ray Redwood, and besides being a Professional radio operator, he was indeed a Ham’s Ham. You will find here not just the story of radio, but a detailed analysis of the Titanic, from a radioman’s point of view. Part documentary, part autobiography, and part technical, it’s a great read. I’m so glad that his work has been preserved here. Future radio historians will, I am certain, find it to be a valuable record of the Ship Radio Officers Era, and Ray’s insights at the dawning of the Global Maritime Distress and Safety System as we have today which utilizes satellite technology.

The Golden Years of Shortwave Listening (YouTube)

There was a time, some 50 years ago when cell phones didn’t exist and computers were only owned by large corporations, that people learned of the world around them by listening to shortwave radio. This is a journey back to that time to hear the sounds and see the correspondence from shortwave stations from all over the world. Sit back, listen and enjoy!

High-Frequency Trading Service: FCC posts two lobbying documents by DPA Mac

10 Replies

Many thanks to SWLing Post contributor, Benn Kobb (AK4AV), who notes that the FCC has posted for public inspection two lobbying documents by DPA Mac, applicant for a new DRM HF broadcast station with 2 kW of transmitter output power.

Benn notes:

“Regardless of DPA’s claims that its broadcasts will be free of charge and not encrypted, its non-broadcast high-frequency trading service will be for paying customers only.

“That is the purpose of this station and is why its target areas, as seen in a world map slide, are limited to the location of certain foreign exchanges. This despite its claim to be a worldwide service.

“There is little profit in SW broadcasting today, and what business there is available is accommodated by those existing US HF stations that can hang on through economic shifts. No, the DPA Mac station is not devoted to global information as a business venture. It wants a license to provide private telecommunications. The broadcasts to the public are just so it can get licensed, because there is no other radio service in the HF spectrum for private international data links.

“At this time no one knows what the FCC will do with this license application and two other similar applications. What is clear is that the applicants want to get on the air ASAP before any possible changes that may affect the HF broadcasting service.”

The FCC posted the following documents in an accessible place on their website yesterday morning:

https://www.fcc.gov/ecfs/document/1110171119378/1

Experimental Radio News 3 (Experimental Radio)

This issue concerns High-Frequency Trading (HFT) transmissions, and three prospective stations seeking entry into the International Broadcast service.

Several stations licensed in the Experimental Radio Service (ERS) transmit data for automated trading to foreign exchanges in the shortwave or high-frequency (HF, 3-30 MHz) spectrum.

High-Frequency Trading (HFT) is a form of automated trading that employs low-latency, high-speed telecommunications to minimize response times. The term is not related to the shortwave or HF spectrum, but this article concerns transmission of HFT messages on HF frequencies.

HF signals can traverse great distances by refraction from ionized layers of the atmosphere, a phenomenon known as ionospheric propagation. Several ERS HFT stations have operated in the HF bands for years out of the public view. Bob Van Valzah blogged extensively about these stations starting in 2018.

These ERS stations’ licenses are public records, but the licensees typically ask the FCC to withhold access to station details and experimental plans. The Commission’s routine acceptance of these confidentiality requests makes public oversight difficult. [Continue reading at Experimental Radio…]

Radio Bulgaria back on shortwave

Many thanks to SWLing Post contributor, Richard Langley, who writes:

As I reported to Glenn Hauser’s group today, Bulgarian National Radio’s Radio Bulgaria is back on shortwave.

Their weekday roughly 22-minute podcast in English, called “Bulgaria Today,” is being aired by ShortwaveService from Kall, Germany, on 3985 kHz from 18:30 until about 18:52 UTC.

Today (30 January), the podcast dated Thursday, 27 January, was broadcast. The program consisted of news, COVID-19 information, weather, travel, and the “Music Slot.” Reception using the U. Twente SDR receiver was fairly good.

There is also a German broadcast before the English one beginning at 18:00 UTC. The ShortwaveService tuning signal is used to fill out the half-hour slot in each case.

All the best

Howard Hesseman, who played Johnny Fever on ‘WKRP in Cincinnati,’ dies at 81 (NPR)

NEW YORK — Howard Hesseman, who played the radio disc jockey Johnny Fever on the sitcom “WKRP in Cincinnati” and the actor-turned-history teacher Charlie Moore on “Head of the Class,” has died. He was 81.

Hesseman died Saturday in Los Angeles due to complications from colon surgery, his manager Robbie Kass said Sunday.

Hesseman, who had himself been a radio DJ in the ’60s, earned two Emmy nominations for playing Johnny Fever on CBS’ “WKRP in Cincinnati,” which ran for four seasons from 1978-1982. The role made Hesseman a counterculture icon at a time when few hippie characters made it onto network television. [Continue reading…]

Obituary: Dame Vera Lynn, a symbol of resilience and hope (BBC News)

Dame Vera Lynn, who has died at the age of 103, was Britain’s wartime Forces’ Sweetheart, and remained one of the country’s most potent symbols of resilience and hope.

With songs such as We’ll Meet Again and The White Cliffs of Dover, she inspired both troops abroad and civilians at home during World War Two.

As Britain’s cities came under attack, her wistful songs, with their messages of yearning and optimism, were heard in millions of British homes.

And 75 years later, the country turned to her once again as it faced another stern test.[…]

London street noises 1928 (Sound and History)

THERE ARE NO BBC radio recordings surviving from before 1931, so the job of representing the 1920s falls to this curiosity from the Columbia Graphophone Company. It’s a 12” 78rpm disc made in 1928 in association with the Daily Mail newspaper.

It seems likely that the disc was somehow tied in with a Daily Mail campaign over urban traffic noise. The commentator on both sides of the disc is a man named Commander Daniel and he doesn’t approve of everything he hears in the city streets.

The recordings were made from single, static locations in Leicester Square and Beauchamp Place on Tuesday 11th and Thursday 20th September respectively. Columbia probably used a recording van equipped with a disc-cutter.[…]

Repoliticizing Voice of America (The Hill)

When Michael Pack takes over as the first politically-appointed CEO of the U.S. Agency for Global Media, his first task will be to comprehend the bewildering array of international broadcasting entities under the USAGM. This includes two government agencies: Voice of America and Office of Cuba Broadcasting (Radio and TV Martí), and four government funded corporations: Radio Free Europe/Radio Liberty, Radio Free Asia, Middle East Broadcasting Networks (the Arabic-language Alhurra and Radio Sawa) and the anti-censorship Open Technology Fund. Within this structure are broadcasting outlets that straddle two entities, such as the Russian-language Current TV. All told, the entities distribute content in 61 languages.

When past that hurdle, Pack must then decide if he wants to maintain the journalistic independence of USAGM’s entities, or if he wants to move them towards advocacy of the administration’s policies.[…]

Companies Pitch Shortwave Radio to Shave Milliseconds Off Trades (Bloomberg)

High-frequency traders will famously do almost anything to get the latest market data and send their buy and sell orders a few milliseconds ahead of the competition. They blasted through mountains to build the most direct fiber-optic routes possible between exchanges in a competition that transformed global markets and was made famous by Michael Lewis’s book Flash Boys. Soon, pinging light through glass fiber at more than 124,000 miles per second wasn’t fast enough—the glass slows things down—so traders moved on to microwave transmitters that send signals through the air.

But that has problems, too. Microwaves travel only roughly as far as the eye can see before they peter out and need a signal boost. Now two rival market telecommunications companies have signed a pact that they say will give traders more access to experimental wireless signals which can travel across oceans.

To do that, signals need a longer wavelength—known as a shortwave rather than microwave—that bounces between the water and atmosphere. It’s an imperfect solution. The waves can handle only a fraction of the data that fiber can, carrying about a kilobit per second vs. gigabits. And some signals can be lost.

Raft Technologies Inc., a startup based in Tel Aviv, says the trade-offs are worth it. Raft says it can send data over shortwave from Chicago to Frankfurt in 31.4 milliseconds, which it says is about 4.5 milliseconds faster than the best available fiber route. That’s an eternity in an industry that tends to measure improvements by the thousandth of a millisecond. The company says the signal is about 85% reliable, compared with 100% for fiber. Clients can use a fiber line in parallel as a fail-safe measure.[…]
