POCSAG (Post Office Code Standards Advisory Group) is a common paging transmission format. Commonly used in in-band telephone dialing. Note however that some modes might require modifications to the radio (especially the 9600 baud FSK and the POCSAG modes) to work properly.ĪX.25 - Amateur Packet Radio protocol datagram format.ĭTMF - Dual Tone Multi Frequency. Currently, the following modes are supported:Īn 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.

The decoding is done completely in software. A standard PC soundcard is used to acquire the signal from a transceiver.
