Shortwave Radio Recordings: The Giant Jukebox and Kim Elliott’s digital text on The Mighty KBC

wurlitzerJukeboxThe Mighty KBC’s broadcast from Bulgaria was mighty strong last night into North America. I recorded the full 2 hour show of The Giant Jukebox on 9,450 kHz beginning at 00:00 UTC.

As I’ve come to expect from The Mighty KBC, this show has an marvelous mix of rock-n-roll through the decades along with Eric’s professional DJing. The Mighty KBC has real people behind the music mix, a refreshing alternative to the iHeart Radio and Pandoras of the world.

Of course, this recording includes Kim Elliott’s digital text modes. For those of you who would like to decode it, here are the details:

At about 01:30 into the recording, 4xPSK63R is centered on 1000 Hz and MFSK64 centered on 2000 Hz. (For 4XPSK63R, use Fldigi 3.21.65 or newer: OpMode > PSKR > MultiCarrier > 4XPSK63R.)

At just before the end of the transmission, an image will be transmitted in the MFSK16 mode. Also, MT63-2000 (long interleave) will be centered on 1500 Hz. This will be an Flmsg formatted transmission, with html. Fldigi and Flmsg can be downloaded from www.w1hkj.com.

Please comment if you were able to decode.

On Friday, May 4, 2012, during Allan Weiner Worldwide (8pm US eastern time, 0000 UTC), we will be presenting an experiment in the transmission of text messages in digital formats. During the show, we will transmit a brief message in MFSK64 format. This message consist of text that listeners can save to a file with an .htm suffix, then open and view it in a web browser.

The message can be decoded using a variety of free software packages. One such package is FLDIGI, which can be found at http://www.w1hkj.com/Fldigi.html.

Thanks to Kim Andrew Elliott, audience researcher at the International Broadcasting Bureau, for coordinating this test.

You can find Allan Weiner Worldwide on 5,110, 7,490 and 9,330 kHz tonight (Friday, May 4th) at 00:00 UTC (20:00 in Eastern US)
