Thanks, Adrian,

I wasn't aware that the UZ7HO soudmodem software now supports 1200 BPS BPSK (as well as a number of other modes). I will give it a try.

Are there any other 1200 baud BPSK demodulators available other than Warbler.jar?

Hi Jan,

I've donwloaded the IQ file and run the demodulated audio through soundmodem. The performance is quite impressive indeed. It was also nice to see the 2400 bps BPSK activity. Soundmodem could decode de 2400 bps BPSK signals quite well.

Last night I monitored QB50p1 with soundmodem and warbler. As Ken has observed, soudmodem decodes about twice more frames. I had the BitRecovery in sourmodem set to 1. This may have helped as well a little.

It would be quite good if FEC was more widely used in amateur satellite projects. Monitoring the BPSK1200 signals from FunCube-1 shows clearly the power of FEC. Sometimes we can barely hear the signal or there is a deep fading and frames are correctly decoded. The BPSK1000 used in ArissSat-1 was another excelent demonstration of the benefits of FEC.

Hi Edson,

You won't regret it, it is a superb sound-modem and also has the ability to serve as a AGW and/or kiss server.

Give my IQ recording on http://janvgils.home.xs4all.nl/download/QB50px/ a go with this version and you'll be astonished
