A Mystery Signal and a Fast Answer from UDXF

Many thanks to SWLing Post contributor Dan Greenall, who write: 

Hi Thomas

I still have a tendency to scan the utility frequencies from time to time, much as I did over 50 years ago. Now, though, I can listen in through the various Kiwi SDR receivers scattered around the globe. Having obtained my amateur ticket in 1974, I got a lot of practice copying the CW repeating “markers”, especially those in the maritime bands.

Recently, on March 20 at 1821 UTC, to be exact, I came across a CW signal repeating the same message over and over on 6839 kHz, while tuning my friend Ken’s Kiwi SDR in Northern Thailand. The text read: VVV Q2M Q2M Q2M de NYZ NYZ

At first, I thought NYZ might be some kind of U.S. military callsign, but I decided to confer with an expert, Ary Boender, at the UDXF in the Netherlands. My e-mail was sent out at 10:57 am local time, and by 11:02 I had my answer! And not at all what I expected.

This is a Chinese military station, Enigma designator M89.
Here is some info about it https://www.numbersoddities.nl/Chinese-military-nets.pdf

My thanks to Ary and the UDXF, the Utility DXer’s Forum. This is a very useful site and I highly recommend it to anyone interested in Utility DXing. Check it out here:

New Persian Numbers Station Surfaces After U.S. Attacks Iran

Many thanks to SWLing Post contributor Paul Jamet who shares this article from Radio Free Europe/Radio Liberty about a Persian-language numbers station that has recently appeared on shortwave:

https://www.rferl.org/a/mystery-numbers-station-persian-signal-iran-war/33700659.html

Long-time shortwave listeners know that numbers stations often seem to surface during periods of geopolitical tension. With the recent U.S. attack on Iran drawing global attention, it’s not surprising that this signal has also caught the eye of the press. Whether or not it’s connected to intelligence activity, it’s a reminder that shortwave radio still quietly plays a role in the background of world events.

New Farsi Numbers Station Reported on 7910 kHz

Many thanks to SWLing Post contributor Richard Cuff, who shares an article from Seth Hettena’s Substack about the appearance of a new shortwave numbers station believed to be broadcasting in Farsi. Numbers stations–mysterious broadcasts that read sequences of numbers–have long been associated with intelligence agencies communicating with field operatives using unbreakable one-time pad encryption. According to the report, this new signal first appeared around the time of recent military strikes involving Iran and has been heard on 7910 kHz. One of our readers reported hearing it around 2:15 UTC recently.

If you capture a recording of this numbers station, please reach out as I would like to add it to the Shortwave Radio Audio Archive. Thank you!

“Old-school static wins the spy wars”

Many thanks to SWLing Post contributor Richard Cuff, who shares this Komando.com piece on how old-school shortwave number stations remain active in espionage. Intelligence services — notably Russia — still send coded beeps and voice-read numbers using one-time pads because radio is simple, anonymous, and hard to trace.

Sure, we’re all shortwave enthusiasts and many of us grew up with number stations abound, but it’s always great to see popular websites pick up on this. Read the full article on Komando.com.

Radio Waves:  Stories Making Waves in the World of Radio

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 Paul, Frank Howell, NT, and Dan Finegan for the following tips:


Russia’s New Mystery Shortwave Station (Hackaday)

The Buzzer, also known as UVB-76 or UZB-76, has been a constant companion to anyone with a shortwave radio tuned to 4625 kHz. However, [Ringway Manchester] notes that there is now a second buzzer operating near in frequency to the original. Of course, like all mysterious stations, people try to track their origin. [Ringway] shows some older sites for the Buzzer and the current speculation on the current transmitter locations.

Of course, the real question is why? The buzzing isn’t quite nonstop. There are occasional voice messages. There are also jamming attempts, including one, apparently, by Pac Man.

Some people think the new buzzer is an image, but it doesn’t seem to be the same signal. The theory is that the buzzing is just to keep the frequency clear in case it is needed. However, we wonder if it isn’t something else. Compressed data would sound like noise.  Other theories are that the buzzing studies the ionosphere or that it is part of a doomsday system that would launch nuclear missiles. Given that the signal has broken down numerous times, this doesn’t seem likely. [Continue reading…]

Remembering Virginia Norwood, the ‘mother’ of NASA’s Landsat program (Engadget)

The pioneering inventor died on March 27th at the age of 96.

If you haven’t heard of Virginia Norwood, it’s about time you did. An aerospace pioneer whose career would have been historic even without its undercurrent of triumph over misogynistic discrimination, she invented the Landsat satellite program that monitors the Earth’s surface today. Norwood passed away on March 27th at the age of 96, as reported by NASA and The New York Times.

She achieved all this despite significant pushback from the male-dominated industry before and after her rise. Despite her obvious talent, numerous employers declined to hire her after graduating from the Massachusetts Institute of Technology. For example, Sikorsky Aircraft told her they would never pay her requested salary, equivalent to the lowest rank in the civil service. Another food lab she applied for asked her to promise not to get pregnant as a condition of her employment. (She withdrew her application.) Finally, the gun manufacturer Remington appreciated her “brilliant” ideas in an interview but told her they were hiring a man instead. [Continue reading…]

Can The Industry And Congress Keep AM Radio In The Dashboard? (Inside Radio)

Facing an existential moment in the 100-year history of the medium, AM broadcasters are banding together, calling on allies in Congress, and enlisting listener support to preserve their place in the automobile. The heads of 10 state broadcasting associations have formed a Dashboard Subcommittee within the National Alliance of State Broadcasters Associations (NASBA) to slow or stop the removal of AM radio from the dashboard. The two-week old group is working on multiple fronts including fact finding, education and advocacy.
