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…]

New miniature antenna can operate wirelessly inside of a living cell (Tech Explorist)

An intracellular antenna that’s compatible with 3D biological systems and can operate wirelessly inside a living cell.

A new study could allow scientists to create cyborgs at a cellular scale, thanks to MIT Media Lab for designing a miniature antenna that can operate wirelessly inside a living cell. This could have applications in medical diagnostics, treatment, and other scientific processes because of the antenna’s potential for real-time monitoring and directing cellular activity.

Scientists named this technology Cell Rover. It represents the first demonstration of an antenna that can operate inside a cell and is compatible with 3D biological systems.

Deblina Sarkar, assistant professor and AT&T Career Development Chair at the MIT Media Lab and head of the Nano-Cybernetic Biotrek Lab, said, “Typical bioelectronic interfaces are millimeters or even centimeters in size and are not only highly invasive but also fail to provide the resolution needed to interact with single cells wirelessly — especially considering that changes to even one cell can affect a whole organism.”

The size of the newly developed antenna is much smaller than a cell. The antenna represented less than .05 percent of the cell volume in research with oocyte cells. It converts electromagnetic waves into acoustic waves, whose wavelengths are five orders of magnitude smaller, representing the velocity of sound divided by the wave frequency — than those of the electromagnetic waves.

Mid Century Television – live, local and unpredictable late 1950s television (Southgate ARC)

In the late 1950s television networks ruled the airwaves from 7 to 11 PM, but outside of that timeslot television was live, local and unpredictable.

Jim Hanlon, W8KGI,  worked as a summer relief engineer at Cincinnati’s WCPO-TV from 1956 to 1958. At that time WCPO-TV did not have any video recording technology, so all local TV was live TV and provided a refreshing dose of live programming, equipment failures and production creativity that been lost in today’s pasteurized, homogenized TV ecosystem.

Join Jim as he recalls what it like producing live TV programming in the early days of television broadcasting.

Jerome’s response from Australian Foreign Affairs regarding shortwave to Pacific

Many thanks to SWLing Post contributor, Jerome van der Linden, who shares the following response from from the Australian Foreign Affairs department regarding any future shortwave services to the Pacific. As Jerome notes, the letter “suggests that all is not yet lost, though it’s lacking in commitment.”

Click here to download a PDF of the response.

Quite correct, Jerome. The letter is noncommittal, but at least acknowledges the government will take this under formal review.  I doubt anyone should hold their breath, of course.

Thank you so much for sharing!

Radio Waves: Waves Around Earth’s Core, New Australian Communications Minister, Shipping Forecast Future, and Hams Accused of Being Spies

Giant Magnetic Waves Have Been Discovered Oscillating Around Earth’s Core (Science Alert)

Earth’s interior is a far from quiet place. Deep below our surface activities, the planet rumbles with activity, from plate tectonics to convection currents that circulate through the hot magmatic fluids far underneath the crust.

Now scientists studying satellite data of Earth have identified something inside Earth we’ve never seen before: a new type of magnetic wave that sweeps around the surface of our planet’s core, every seven years.

This discovery could offer insight into how Earth’s magnetic field is generated, and provide clues of our planet’s thermal history and evolution – that is, the gradual cooling of the planetary interior.

“Geophysicists have long theorized over the existence of such waves, but they were thought to take place over much longer time scales than our research has shown,” says geophysicist Nicolas Gillet of the Université Grenoble Alpes in France.

“Measurements of the magnetic field from instruments based on the surface of Earth suggested that there was some kind of wave action, but we needed the global coverage offered by measurements from space to reveal what is actually going on.

“We combined satellite measurements from Swarm, and also from the earlier German Champ mission and Danish Ørsted mission, with a computer model of the geodynamo to explain what the ground-based data had thrown up – and this led to our discovery.”

Earth’s magnetic field is the subject of much fascination for scientists. Research to date suggests that the invisible structure forms a protective ‘bubble’ around our planet, keeping harmful radiation out and the atmosphere in, thus allowing life to thrive. [Continue reading…]

‘A link across time’: how shipping forecast will outlast Radio 4 long wave (The Guardian)

Boats have not needed the broadcast for decades but radio bosses know nostalgia for it runs deep

Radio 4’s shipping forecast is a national institution, with millions of listeners reassured by the thought that, somewhere out at sea, British fishers are patiently waiting by their radios to find out whether there is a gale warning in Rockall or Cromarty.

Yet the announcement that Radio 4’s long wave signal will be shut down as part of the BBC’s latest cuts has left many wondering how the country’s fishing fleet will cope without access to the four-times-a-day updates.

The slightly less romantic reality, according to Mike Cohen of the National Federation of Fishermen’s Organisations, is that his members have not needed Radio 4 for decades. Modern fishers have far more accurate devices to warn them about the wind and rain: “Even the small 15-metre boats in Bridlington have satellite internet these days. I’ve had video calls from people in the middle of the sea.”

Yet that does not mean they are immune to the charms of Sailing By, the music that heralds the forecasts and was designed to help captains adjust their radios: “That theme tune is a link to other times, other people, other places. There’s as much a fondness among fishermen for that as there is for the rest of us.”

When the fishers’ trade body asked its members how they felt about the shipping forecast one said it “acted as a link across communities, a link across time”. Another added: “For us it is a bygone age but for many older folk it is a reassuring connection to the past.”

The BBC plans to end dedicated programming on its Radio 4 long wave frequency next year, which could mean the loss of two of the current four shipping broadcast updates. The early morning and late night forecasts will remain on FM, DAB and online broadcasts. But the loss of the long wave signal – accessible far from the British mainland – confirms they will essentially be nostalgia pieces, more about waking the nation up or lulling listeners to sleep.

Two Brits arrested in Albania as police accuse them of spying after seizing radio gear (Southgate ARC)

Two Britons were quizzed on allegations of espionage by officers at Tirana International Airport in Albania after police discovered sophisticated Kenwood radios in their luggage

Two Britons have been arrested by Albanian spooks and accused of spying after border police found radio transmitters in their luggage.

The pair were quizzed on allegations of espionage by officers at Tirana International Airport after they discovered sophisticated Kenwood radios in their luggage.

They told the officials they were IT engineers who were carrying the amateur gear to indulge their hobby while on holiday in Albania.

One suspect was registered as using a “ham radio” in the Tirana region on online profiles, which also say he specialises in “electronic warfare”.

Albanian police confirmed that they have opened a probe over allegations of “spy activities” and “espionage”.

A source said: “It’s highly unusual to be carrying this sort of equipment and even more strange for someone to be stopped and accused of being a covert agent.”

The two Britons were held on May 30 and then allowed to return to the UK. However they remain under investigation, police say. The electronic kit by Kenwood – which makes a range of cutting edge communication devices – was sent to the Albanian Criminal Laboratory for further examination.

Ukraine war: Russian strike on Kyiv kills reporter Vira Hyrych (BBC News)

A journalist working for Radio Liberty in Ukraine was killed in Russian rocket strikes on Kyiv on Thursday evening, the station has confirmed.

Vira Hyrych was at home when a rocket hit the residential building where she lived in the capital, it says. Her body was pulled from the wreckage on Friday.

She “will be remembered for her professionalism and dedication to our mission”, the US-funded station says.

Kyiv was hit as UN Secretary General António Guterres was visiting the city.

The UN chief – who only a day earlier had held talks in Moscow with Russian President Vladimir Putin – said he was “shocked” by the Russian attack.

Ukrainian President Volodymyr Zelensky accused the Kremlin of trying to humiliate the UN, while Kyiv Mayor Vitaliy Klitschko said the Russian leader had shown “his middle finger” to Mr Guterres.

Moscow has confirmed it hit Ukrainian targets, but has not commented on the strike on the building.

“We are deeply saddened by the death of our Ukrainian Service staffer Vira Hyrych in Kyiv overnight,” Radio Liberty President Jamie Fly said in a statement.

“We are shocked and angered by the senseless nature of her death at home in a country and city she loved. Her memory will inspire our work in Ukraine and beyond for years to come.” [Continue reading…]

The Sullivans: Could WWII German broadcasts be easily received in Australia?

Many thanks to SWLing Post contributor, Ray Robinson, who writes:

Hi, Thomas. I have recently been re-watching the Australian soap serial ‘The Sullivans’, which ran on Channel 9 from 1976-1983. I used to watch it on ITV in England, and also for awhile on the Tempo cable & satellite channel here in the States in the late 80’s. It is set in Melbourne during the second World War and after, and begins in September 1939. In the episodes covering the early part of 1940, much is made of one of the character’s abilities to listen to Nazi German broadcasts via shortwave, in both English and German (and they play clips of actual audio in the episodes). My question is, how realistic is this?

Were German broadcasts at that time able to be heard with good quality in Australia? Does anyone have a transmission schedule from that era? I know that German broadcasts were well heard throughout Europe and in North America, but I don’t have any details of broadcasts targeting Australia. Might they have been relayed via some Axis transmitter in the Far East? If any of your SWLing Post readers can shed any light on this, I’d be very grateful. Thank you.

Ray Robinson

Great question, Ray. This is certainly an inquiry for radio enthusiasts and WWII buffs in Australia and New Zealand. I’m sure there are accounts out there that could verify how easily and frequently Axis broadcasts could be heard in Australia and NZ. My guess would be that propaganda would have certainly targeted Australia and New Zealand during WWII.

Please comment if you can provide some insight and/or evidence for Ray!

RadioInfo: “Fires hit ABC Radio’s Batemans Bay transmitter”

Photo by Benjamin Lizardo

Many thanks to SWLing Post contributor, Michael Bird, who shares the following story from RadioInfo.com.au:

In an example of radio industry cooperation during adversity, commercial network Grant Broadcasters is working with the ABC on the South Coast of NSW to keep transmissions on air during the fires in that area.

As fires raged through the area last week, the ABC’s Mt Wandera transmission site at Bateman’s Bay was disabled by flames (see pictures below) and is expected to take some time to repair.

The ABC, through its transmission provider Broadcast Australia (recently renamed BAI Communications) asked if it could share Grant Broadcasters’ nearby transmission mast and infrastructure, and has now combined its transmissions onto the Grant Broadcasters antenna.

Local radio services, including ABC South Coast, are now back on air, but operating at reduced power. The ABC’s television transmitter on the site is also off air.

BAI has also established additional temporary low power facilities at Batemans Hill for ABC Local Radio (operating on 101.9 MHz) and ABC television (operating on Channel 41).  As this facility operates from a lower altitude and at lower power than those at Mt Wandera, its coverage will be largely limited within the town of Batemans Bay.

On the South Coast, the Grant Broadcasters stations 2EC and Power FM  had “no issues with transmission coverage” and have so far remained on full power. Diesel generators have 4-5 days capacity and are being refuelled continuously.

[…]Communications Minister Paul Fletcher has commended media and transmission providers for their efforts to keep services operating:

“I commend the network operators’ efforts in responding, which has included deploying temporary facilities to restore communications services for impacted communities, particularly those that are isolated. Many of the outages are due to power supplies being cut off, and in some cases are the direct impact of fire on network infrastructure. The current fire situations across Australia have made access difficult and unsafe at some sites to assess and restore services…

“In many cases, a portable transistor radio with a spare set of batteries is a vital way to receive emergency information, in the event there is a loss of mains power or mobile coverage.

“The ABC and other local radio stations are doing an excellent job transmitting vital emergency information to Australian communities. Telstra and Optus are offering targeted relief packages in affected regions in NSW and Victoria, including free use of payphones, call diversions from affected lines and other financial assistance.”[…]
