At the request of the ALMASAT team AO-51 will switch to V/S 38k4 digital operation from about 0100Z on 15Mar2007 to 0200Z 16Mar2007.

If anyone has the appropriate (wide enough) S-band receiver, but not the 38k4 modem, you can make a recording of the 38k4 signal with a soundcard and a program like REC48000.exe -- then demodulate the signal "later".

38k4 demodulation is also possible using just a soundcard with a program like Willow. If you're interested, email me!

I wonder if anyone on the ALMASAT team could make a recording of their 38k4 transmissions before launch?
