As POCSAG in originality is FSKFrequency-Shift Keying, the reality is, if read in FMFrequency Modulation, its actually read as a pulse train. Companies utilize these AFSKAudio Frequency-Shift Keying modes for multimode ops, or for simple end-end link transmission on another frequency. (See Glenayre Paging Link for details).
A couple of examples generated from a dutch POCSAG encoder plugin and FMFrequency Modulation modulated in an audacity plugin:
The result when AFSKAudio Frequency-Shift Keying is mixed in with Flex @6400 BaudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second.:
