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’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors Dennis Dura and Dan Robinson for the following tips:


The Russian Woodpecker: Official Bird Of The Cold War Nests In Giant Antenna (Hackaday)

On July 4th, 1976, as Americans celebrated the country’s bicentennial with beer and bottle rockets, a strong signal began disrupting shortwave, maritime, aeronautical, and telecommunications signals all over the world. The signal was a rapid 10 Hz tapping that sounded like a woodpecker or a helicopter thup-thupping on the roof. It had a wide bandwidth of 40 kHz and sometimes exceeded 10 MW.

This was during the Cold War, and plenty of people rushed to the conclusion that it was some sort of Soviet mind control scheme or weather control experiment. But amateur radio operators traced the mysterious signal to an over-the-horizon radar antenna near Chernobyl, Ukraine (then part of the USSR) and they named it the Russian Woodpecker. Here’s a clip of the sound.

The frequency-hopping Woodpecker signal was so strong that it made communication impossible on certain channels and could even be heard across telephone lines when conditions were right. Several countries filed official complaints with the USSR through the UN, but there was no stopping the Russian Woodpecker. Russia wouldn’t even own up to the signal’s existence, which has since been traced to an immense antenna structure that is nearly half a mile long and at 490 feet, stands slightly taller than the Great Pyramid at Giza.[]

A Spy in Every Embassy (Southgate ARC)

‘The intelligence coup of the century’. The extraordinary story of the longest running and most successful secret intelligence operation of the 20th Century.

For more than half a century, governments all over the world trusted a single company, Swiss-based Crypto AG, to keep the communications of their spies, soldiers and diplomats secret. But what none of its customers ever knew was that Crypto AG was owned for over 20 Cold War years by the CIA in partnership with the BND, the German Intelligence Service. The machines that many customers bought had deliberately weakened security – a window through which the CIA and BND could read the diplomatic traffic between their embassies, their trade negotiators and their own spies.

The BND sold out its share in 1993 for a tidy profit while the CIA continued until the company was broken up in 2018.

Crypto AG’s own secret was only cracked last year in a combined investigation by German ZDF television, Swiss SRF and the Washington Post following the discovery of a secret history, Operation Rubicon, that had been assembled by some of the operatives who had been involved in the deception.

A Spy in Every Embassy is the story of the story, presented by German intelligence journalist Peter F Muller, who produced last year’s television programme for ZDF, and British journalist David Ridd.

It gives the chronology of the manoeuvrings, arguments, successes and deceptions of the partnership that remained secret for a quarter of a century. Its revelations offer a new perspective on some of the landmark events of those decades – the Falklands War, the US bombing of Libya from British airfields, the negotiations that lead to the Camp David Accords and the Iranian Hostage crisis, as well as the daily churn of intelligence information from around the world about both friends and opponents.

The programme considers the collateral damage of deception on a grand scale. Most employees of Crypto AG knew nothing of the built-in weaknesses of the machinery they were building or trying to sell to governments in some very dangerous parts of the world.

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’s Radio Waves, a collection of links to interesting stories making waves in the world of radio. Enjoy!

Many thanks to SWLing Post contributors TomL, Alan, Bruce Atchison, and Troy Riedel for the following tips:


Belka DX Shortwave Receiver – Closest Thing To A Spy Radio? (HRCC via YouTube)

Sinclair Launches ATSC 3.0 Test Site; Partners With Fraunhofer On Mondiale Service Integration (ATSC)

HUNT VALLEY, Md.—Mark Aitken, senior vice president of advanced technology at the Sinclair Broadcast Group, flipped the switch on a 100w transmitter to begin broadcasting ATSC 3.0 from atop the station group’s corporate headquarters here with the express purpose of testing reception on small devices like its MarkONE 3.0-enabled smartphone and, in particular, integration of Digital Radio Mondiale (DRM) in its broadcast app.

The launch comes on the same day Sinclair and German technology research institute Fraunhofer IIS jointly announced they are working together to bring audio services using the DRM standard to ATSC 3.0. (Earlier this year, Sinclair rolled out 3.0 simulcasts of its Seattle radio stations with its DRM-based broadcast app.)

“We are actually building the DRM radio service into the [3.0] broadcast app environment,” says Aitken. “That means those [DRM] services will be carried in band and transported just like HEVC [high efficiency video coding] and [Dolby] AC-4.”[]

Clear Frequencies Requested for Net Providing 24/7 Coverage of St Vincent Volcanic Eruption (RAC Newsletter)

For immediate release:
April 20, 2021 –

The Caribbean Emergency and Weather Net (CEWN) has been providing round-the-clock coverage during the La Soufriere volcanic eruption on the island of Saint Vincent and the Grenadines.

Several neighbouring islands are also being affected by the disaster.

When responding to disasters and emergencies such as this, the CEWN utilizes 3.815 MHz LSB and 7.188 MHz LSB. CEWN is requesting that Radio Amateurs not involved in the volcano response to keep these frequencies clear.

Geomagnetic storm warning (Spaceweather.com via Southgate ARC)

A CME is heading for Earth and it could spark a geomagnetic storm when it arrives on April 25th.

NOAA forecasters say moderately strong G2-class storms are possible, which means auroras could dip into northern-tier US states from Maine to Washington.

Video: Josh’s Lab599 TX-500 Deep Dive & Review

Many thanks to SWLing Post contributor, Don (W7SSB), who notes that Josh (KI6NAZ) at Ham Radio Crash Course has just posted his final TX-500 video. If you’ve been considering the TX-500, it’s very much worth your time:

Josh is actually sending me this very same TX-500 for review in The Spectrum Monitor magazine and here on the SWLing Post.

Please comment if you have any questions and I’ll do my best to answer them while I have the unit here at SWLing Post HQ.

Video: Josh takes us on a tour of the lab599 Discovery TX-500 QRP transceiver

Many thanks to SWLing Post contributor, Josh (KI6NAZ), who shares a link to his YouTube channel where he takes us on a tour of the lab599 TX-500 Discovery:

Click here to check out Josh’s channel, Ham Radio Crash Course on YouTube.

Thanks for sharing this, Josh! The TX-500 is certainly a unicorn in the world of field-portable QRP radios since it’s designed to be weather-proof.

lab599 has confirmed that they will dispatch a TX-500 loaner unit for my upcoming review.  I’m looking forward to see how it plays in the field and might compare with other QRP rigs in my arsenal!
