Linux Radio Transmission Decoder

multimon

Linux Radio Transmission Decoder

The multimon software can decode a variety of digital transmission modes commonly found on UHF radio. A standard PC soundcard is used to acquire the signal from a transceiver. The decoding is done completely in software. Currently, the following modes are supported: AX.25 1200 Baud AFSK 2400 Baud AFSK (2 variants) 4800 Baud HAPN 9600 Baud FSK (G3RUH) POCSAG 512 Baud 1200 Baud 2400 Baud Miscellaneous DTMF ZVEI An arbitrary set of the above modes may run concurrently on the same input signal (provided the CPU power is sufficient), so you do not have to know in advance which mode is used. Note however that some modes might require modifications to the radio (especially the 9600 baud FSK and the POCSAG modes) to work properly. POCSAG (Post Office Code Standards Advisory Group) is a common paging transmission format.
