CPX Data Decoder
CPX Data Decoder decodes beacons from Cal Poly's CP6 satellite and forwards received packets to More dBs. By running CPX Data Decoder, you are helping Cal Poly's Polysat project collect on-orbit data from their satellites. Any packets you receive will be stored in a database and visible in CP6's pass log.
CPX Data Decoder works with any TNC that sends KISS-encoded data over a serial port. MixW is a software TNC for Windows that can decode an AFSK signal from your sound card and emulates a serial TNC that is compatible with CPX Data Decoder.
CPX Data Decoder is written in Python and licensed under the GPL. The source code for CPX Data Decoder is available here.
