SWLing Post reader, Steve Yothment (WD0HGB), writes:

“I received an “audio QSL” card from STF Radio International a few days ago. Have you heard about it? [The QSL] actually has grooves on the card that you can play on a phonograph. I had a friend play the audio on his phonograph and he converted the audio to MP3 format. Then, I decoded the digital info in the file.”

Steve decoded the digital data from the audio QSL card and documented the contents on a PDF document.  Click here to download.

Steve: this is brilliant!  Thank you not only for sharing the QSL card images, but for the audio and your excellent documentation of the digital decode!

Readers: What’s the most interesting QSL card you’ve ever received?

STF Radio International this weekend via KBC

STFradioLast week, I received an email from STF Radio International, a new venture that broadcasts digital modes over shortwave (similar to VOA Radiograms). I asked for a description of their mission–here’s their reply:

“STF Radio is primarily a narrowcasting project, a means to deliver specialized content to specific audiences in remote locations. And due to the nature of shortwave, we’re inviting the world to listen in.

The (possible) series of special multimedia broadcasts will continue the exploration of new possibilities with aging technology. We are currently preparing a 1-hour program for broadcast later in April. Depending on audience response, there may be additional programs throughout the year.

We will continue running tests leading up to the 1-hour show. The second round of tests will begin soon, with another segment of digital modes confirmed for this weekend on The Mighty KBC, same time/frequency as last weekend.”

If you would like to decode STF Radio International‘s broadcast, tune in The Might KBC on 7,375 kHz, April 6, 2014 from 00:00 – 2:00 UTC (Saturday evening in North America). STF indicates that their broadcast will be between 01:30 – 2:00 UTC.
