CUBEX now has a working brain! It's currently sending out its name, packet number, time, lat, long, altitude, satellite count, error codes, and a checksum (RTTY 50baud 7n2 on 434.480Mhz). The next step will be to grab the jpeg off the camera and send it out at 600baud (ssdv). Special thanks to Upuaut and Fsphil for their awesome code and help!
