My Fellow Radioamateurs,

In the last couple of years our group here at DTU in Denmark have been working hard to realize the communication system for our next cubesat satellite DTUsat-2. We have developed a full duplex system which has a 38400bps MSK-modulated downlink as well as CW beacon at 2401.835MHz (220mW output power), and a 9600bps FSK-modulated uplink at 1268.9MHz.

However, we have just completed the uplink section, but have as of yet no means of conducting a bit error test of the system. In short we have no means of actually producing a 9600 bps FSK-modulated signal at 1268.9MHz to test the uplink system with, and it will probably be another 4-6month before our GNU software defined radio system to do so is completed. As such, I would like to ask if anyone in the Amsat community has equipment capable of producing such a signal, or could come up with an idea as to how we conduct this test in a quick-n-dirty fashion?

Best Regards
