Whistler scanners tell you also....



Whistler ?... what way does it tell you ? I do see a T displayed at the top when on a DMR channel, does that mean TDMA ? I don't know if any FDMA near me so I can't be sure.

Actually, my assumption was that the question was about P25. Whistler displays "DG" for digital/Phase 1 (FDMA) and "D2" for P25 Phase 2 (TDMA).

DMR is TDMA by default...

NXDN is essentially FDMA.

P25 is the only type (I believe) that can be FDMA or TDMA (at least for scanners) as far as I know.

I am looking for software which will tell me if a P25 TG is FDMA or TDMA. I have been running UniTrunker.

Unitrunker does tell you. In the top section, if you see the same frequency appear twice under separate LCN's beginning with different digits, then you have TDMA.
