If someone will build a linear PSK-31 transponder, I have a launch
opportunity in 9 months.

All it needs to be is a PSK31 Linear receiver on 28.120 MHz (3 KHz
bandwidth) with AGC coupled to a downlink UHF FM transmitter of about 1
Watt.  Should fit on a 3.5" square card.  This is the same as Brno
University has built for prior missions of PCSAT2 on the ISS back in 2006
and the two on the shelf awaiting flights.

Flight delivery by May 2014 (9 months from now).

Brno, may not have the man power to make a third one for this new flight

Jusst a thought for someone looking for a project.
