Many thanks to SWLing Post contributor, Bruce Atchison, who who shares this short video from the early 1980s showing a glimpse inside Radio Venceremos:

From Wikipedia:

Radio Venceremos (Spanish; in English, “‘We Shall Overcome’ Radio”) was an ‘underground’ radio network of the anti-government Farabundo Martí National Liberation Front (FMLN) during the Salvadoran Civil War. The station “specialized in ideological propaganda, acerbic commentary, and pointed ridicule of the government”. The radio station was founded by Carlos Henríquez Consalvi (Santiago).

Despite the end of the war in 1992, the network continues to broadcast. The war years of the station and its national and international influence were documented in the Spanish-language book Las mil y una historias de radio Venceremos and its English translation, Rebel radio: the story of El Salvador’s Radio Venceremos, by the author José Ignacio López Vigil (translator: Mark Fried), a book recorded by the American Library of Congress. An exhibit honoring Radio Venceremos, including a studio room with original equipment, forms a prominent part of the Museum of the Revolution in Perquín, Morazán, El Salvador.

I also found this film on YouTube (The Radio Venceremos Story) which sheds a little more light on the station. The recording is low-resolution, but the subtitles are legible:

Video: Excellent aircraft scatter demonstration

Many thanks to SWLing Post contributor, Robert Gulley, who shares this fascinating video from the Alps DX YouTube channel. In this short demonstartion, you can follow the flight path of an Airbus A320 and the signal from France Musique from Marseille as it is bounces off of the aircraft. Fascinating:

Description from YouTube: France Musique from Marseille / Grande Etoile on 94.2 received via Airscatter. I’m always amazed when I see and hear those signals coming out of nowhere when the plane crosses the path … Nothing a few seconds before, nothing right after. Radio is magic !

Equipment : ELAD S2 SDR + SDR# v1357, Airscout v1.1, 5 element Yagi (polar H).

I find this amazing. I’ll be the first to admit that I’ve never attempted FM aircraft scatter. Since I have an ADS-B receiver, and several excellent FM receivers, all I really need is a decent Yagi antenna and some careful planning.

Post Readers: Please comment if you’ve logged stations from aircraft scatter! Any tips?

The Requiem For Radio QSL Card (Source: RFR Facebook)

I received a number of messages from Post readers who logged one or more of the simultaneous Requiem For Radio broadcasts. Many discovered that each frequency of the broadcast was actually a separate track of the piece.

Indeed, SWLing Post contributor, Shelby Brant, posted the following comment yesterday:

Listening right now, 11580, 9690, 9620, and 5130 are on, but nothing on 6850. To get the most out of this you really ought to have a receiver on all the frequencies at the same time, because each station is broadcasting something slightly different, but if you listen to all at the same time, they go together.

Later, Shelby added:

Here’s a link to a very impromptu video I put together of how I was listening to the broadcast, I managed to gather up 4 receivers (this was after I posted earlier) and tuned them to the 4 active frequencies. Part way through I turn the other three receivers down and tune to the individual stations one at a time to give an idea of what the 4 sounded like on their own, then it goes back to all 4 together again for the end of the video

Enjoy

And what a unique listening opportunity this presents us (thank you, Amanda Dawn Christie!).

How Far We’ve Come: Looking Back at Radiotelegraphy, 1939 Style

It’s often insightful to look to the past to fully appreciate the current technology we take for granted.

When we tap a favorite contact’s name in our mobile phone–even for someone on the other side of the world–we can be talking to them within seconds, with clarity that’s often the equal of visiting face-to-face. Perhaps Skype or FaceTime is more your style? Yawn… just another two-way, real-time video session. The fact that the other person is thousands of miles away no longer makes you pause at the wonder of it all.  Continue reading →
