Fliegl, DG9MHZ What does POCSAG mean? POCSAG is an abbreviation of Post Office Code Standard Advisory Group. This group has developed the most common protocol for paging-systems. A pager is a little box with a receiver and decoder for POCSAG signals. For instance, if m1,m2,m3, and m4 are the symbols of a 4-ary system, we can associate the “dibit” 00 to m1, 01 to m2, 10 to m3 and 11 to m4. Each one of the M symbols is usually represented by a unique signal that lasts for Ts seconds. The message signal is thus one of M discrete possibilities. We call Ts the symbol duration and 1 Ts Chinese 4+4 is a multi-carrier transmission mode. It consists of 8 carriers. They are 300 Hz apart, execpt the 4 th and 5 th carriers, which are 450 Hz apart from each other. useful when fading occurs or signal level is low. The IC-R9500 can recreate the carrier signal exactly by using the DSP. In addition, upper or lower sideband demodulation for S-AM is selectable for eliminating interference from adjacent strong signals. FSK demodulator & decoder The IC-R9500 has built-in FSK demodu-lator and decoder. The UUID version is represented by the 13th digit of a hexadecimal UUID string ("M" in the diagram below).
