We have developed a full duplex system which has a\n38400bps MSK-modulated downlink as well as CW beacon at 2401.835MHz (220mW\noutput power), and a 9600bps FSK-modulated uplink at 1268.9MHz.\n\nHowever, we have just completed the uplink section, but have as of yet no\nmeans of conducting a bit error test of the system. In short we have no\nmeans of actually producing a 9600 bps FSK-modulated signal at 1268.9MHz to\ntest the uplink system with, and it will probably be another 4-6month\nbefore our GNU software defined radio system to do so is completed. As such,\nI would like to ask if anyone in the Amsat community has equipment capable\nof producing such a signal, or could come up with an idea as to how we\nconduct this test in a quick-n-dirty fashion?\n\nBest Regards\n\nJonas Bjarnoe\nOZ2DTU\nOZ3AGY\n\nDTU Space\nDanish Technical University\nElektrovej, Building 237\n2800 Lyngby, Denmark\n", "attachments": [] }
