VOA Radiogram Takes On Firedrake!

From Kim Andrew Eliott:

Hello friends,

The VOA Radiogram experiment enters an interesting new phase with MFSK32 text included in the shortwave broadcasts of the VOA Mandarin Service.

Beginning UTC Sunday at 2258 UTC (Monday morning in China)...

There will be 1:10 (1 minute, 10 seconds) of MFSK32 in Chinese beginning at..

2258:15 UTC        6135  9845 kHz


0058:10 UTC        9880 15385 15565 17560 kHz

These transmissions will continue for two weeks. The transmissions are via VOA relays stations in Asia.

The MFSK32 will be Chinese characters.  You will need the UTF-8 character set.  In Fldigi: Configure > Colors & Fonts.

Usually there will be Chinese domestic radio jamming VOA on the same frequency. It will therefore be MFSK32 versus the Chinese jamming.

I know that most of you are outside of the target area for these VOA Mandarin broadcasts directed to China, but you might be able to hear these transmissions on at least one frequency.

If you can hear these broadcasts, it would be very helpful if you can send me recordings (mp3 is OK), including at least one minute before the MFSK32 begins.

The weekend English broadcasts of VOA Radiogram will continue.




Hello friends,

As a follow-up to my previous email about the MFSK32 on VOA Mandarin, I want to clarify that these transmissions will be daily for the next two weeks, at least.

2258:15 UTC        6135  9845 kHz

0058:10 UTC        9880 15385 15565 17560 kHz

The transmissions are via IBB relay stations in Asia.

The MFSK32 will be Chinese characters. You will need the UTF-8 character set. If using Fldigi: Configure > Colors & Fonts.

If you are unable to hear these frequencies from your location, perhaps you can via the University of Twente SDR receiver: -- or a web controlled receiver in Asia, if you have access to one.

Please send reception reports to . Audio recordings, including a minute or two before the MFSK32 starts, would be especially helpful – even if you can’t decode the tones. Mp3 files are OK. 

The English VOA Radiogram broadcasts on weekends will continue.
