Shortwave listening and everything radio including reviews, broadcasting, ham radio, field operation, DXing, maker kits, travel, emergency gear, events, and more
Many thanks to SWLing Post contributor Markku for sharing this Yle News story about an FM propagation opening along Finland’s eastern border. On a warm July morning, residents of Lappeenranta suddenly found their radios picking up multiple Russian FM stations—some from as far away as St. Petersburg, over 200 km away!
The cause? A temperature inversion and high-pressure system.

Good afternoon, Thomas. Recalling that there have been a few postings on the SWLing Post over time on the FCC’s Radio Intelligence Division, I thought this might interest you and some readers. I just came across this (I don’t even remember what linked me to it) and have only briefly looked reviewed it, but the manuscript appears to be pretty interesting. https://www.qsl.net/w3df/sterling/ridhist.pdf
An interesting local (to me) tidbit on page 19: “It [RID] patrolled the outside of the Oak Ridge, Tennessee installation, the scene of the Manhattan Project but without the personnel knowing what atomic developments were being made inside.“

The Voice of Mongolia from Ulaanbaatar was always tough to hear from my location in southern Ontario, Canada. Relatively quiet conditions and a clear frequency eventually allowed me to make a recording of their interval signal and bilingual identification (presumed Mongolian and English) on November 1, 1998. This was on 12085 kHz at 1230 UTC. I was using a Panasonic RF-3100 portable receiver and a very long wire antenna.
Recording #1 November 1, 1998 1230 UTC 12085 kHz sign on in English (received in Ontario, Canada)
Today, reception of their programs still seem to be challenging, even with the use of remote SDR’s. Their schedule runs from 0900 to 1100 UTC on 12085 kHz, and again from 1300 to 1500 hours on 12015 kHz. Half hour English language segments begin at 0900 and 1430. Their distinctive interlude tune has remained the same through the years.
Recording #2 July 11, 2025 1300 UTC 12015 kHz sign on in Japanese (used Korean SDR)
Recording #3 July 12, 2025 1430 UTC 12015 kHz Chinese ending then sign on in English (used Korean SDR)
Greetings to all SWLing Post community, here’s this week’s shortwave transmissions from the Imaginary Stations crew.
There’s more “get on that board” madness with SURF 2 on Saturday 19th July 2025 at 1100 hrs UTC on 6160 kHz and then again on Sunday 20th July 2025 at 0900/1300 hrs UTC on 6160 kHz and at 2000 UTC on 3975 kHz and 6160 kHz (via the services of Shortwave Gold).
Get that convertible out of the garage, load it up with your surfboard then leave it out on the drive. Turn on your receiver indoors, make sure those (short)waves are active and enjoy an hour of the best surf related tunes. Remember “Let’s go surfing now, turn on your radio, that’s how, join us on the high frequent seas” and hang loose!
And we’ve got another episode of COOL on Wednesday 23rd July 2025 at 0200 hrs UTC via WRMI. Think sunshine vibes and chilling out on a deserted beach somewhere with a shortwave wind up portable. Enjoy the summer with COOL!
Here’s a trailer about riding the shortwave SURF to get you in the mood.

After the recent tragedy in Texas, I realized a lot of people might be looking for weather radios. So, I decided to make a video on that topic which I believe will be informative for just about everyone.
Even some of the knowledgeable members will have a video they can refer their family and friends to for further education and guidance:
