The Fox-1 series of CubeSats will be capable of transmitting continuous telemetry during normal transponder operation, while contacts are taking place. The satellites will feature slow-speed (200 bps) telemetry data that accompany transponder audio or voice ID activity. The slow-speed data are contained in the audio spectrum below 300 Hz. Using DSP techniques, high-pass filtering is applied to …
