Here we play radio: shortwave, mediumwave, longwave, amateur/ham radio, pirate radio, utilities, digital modes, scanning and more. We share radio reviews, broadcasting news and anything we radio geeks enjoy. Welcome to the SWLing Post community!
The German communications regulator Bundesnetzagentur has changed its mind about allowing digital modes on shortwave broadcast transmitters in Germany. Apparently BNetzA thought that Channel 292 was transmitting the text and images in single sideband (SSB), which is how amateurs, military, etc, transmit the digital modes. Now that they know that the MFSK32 and other modes are sent as program audio on an analogue amplitude-modulation shortwave transmitter, their objections were withdrawn. (It’s similar to A2A modulated CW.)
BNetzA prefers that the term MFSK32 not be used to describe these broadcasts, but we have to specify the mode so that you can set Fldigi or other decoding software to the correct mode. In any case, the weekly MFSK32 transmission will resume on The Mighty KBC, and DigiDX will return to Channel 292.
Meanwhile, VOA Radiogram this weekend will be all MFSK32 except for the transmission schedule in Olivia 64-2000 under the closing music.

[Below, you’ll find] my reception report for the digital decode of the Fldigi message by Dr. Kim Elliott on The Mighty KBC (6040 kHz) Saturday night:
I took Kim Elliott’s suggestion and listened to The Mighty KBC on 6095 kHz on Sunday morning using the Utwente WebSDR which receives signals in Enschede, in the Netherlands.
The Mighty KBC finished their last broadcast on 6095 kHz at 11:00AM our time. I recorded their program, but the file is big. So, attached is the last 4 minutes of their program (click here to download), as received by the WebSDR:
It’s too bad that The Mighty KBC is shutting down!
Many thanks for both your decoded message and your recorded audio, Steve! I agree: it is too bad the KBC had to shut down their 6095 kHz broadcast.
