What means "PX0 or PX1" icon

henrygb · Oct 27, 2014

I'm listening a new system, not sure if it is P25, or P25 X2-TDMA, when somebody talk the DAT icon is remplaced by PX0 or PX1. What means it? No found info in user manual.

P25 Phase II TDMA has 2 channels per frequency; 2 users alternate broadcasting on the same frequency. One is PX0, the other is PX1.

ok, then it´s possible this system could be P25 Phase II TDMA, or P25 X2-TDMA. I will try with both settings. It is a new system, and no reference in anywhere

If it's truly "new" it won't be X2.

PX0 is X2 Time slot 0
PX1 is X2 Time slot 1

PT0 is P25 Phase II Time slot 0
PT1 is P25 Phase II Time slot 1

There is no such thing as P25 X2.

This system could be hybrid? now sometimes the DAT icon change to LNK and P25.
PX0, PX1, and P25 in the same system?

Sounds like a P25 Phase II system operating in Phase I compatibility mode. All those indicators could be shown on such a system.

Sounds like an X2 system with some fdma talkgroups.
