Short Description It is easier to transmit the FSKFrequency-Shift Keying pager signal to the transmitter site as AFSKAudio Frequency-Shift Keying. It is changed to POCSAG format when re-transmitted.
I/Q Raw Recording
Audio Sample

It is easier to transmit the FSKFrequency-Shift Keying pager signal to the transmitter site as AFSKAudio Frequency-Shift Keying. It is changed to POCSAG format when re-transmitted.

The main signal is FMFrequency Modulation modulated in other modems and is re transmitted on another frequency. This allows for more simplicity and much less power. That is why this mode is used in larger networks to reduce the cost of money.....

Decoding Software[edit]

PDW: But you will need either an extractor cable to extract the raw bits and put them into PDW itself, or modify/add source code to recieve audio tones.
