I decided to check out some 800 mhz. trs within my ground wave coverage using my PSR600 in the tune mode and manually entering the control channel. I also have Pro96com running to possible id a new trs. One trs I presently have enough signal strength for my really deaf (poor sensitivity) PSR600 compared to my 996XT displays an alternating "M36" and "FM". I assume this is iding the control channel as a Motorola 36000 baud transmission trs. Is that correct? Pro96com does not like it I guess because it is a Motorola version of P25 and not a "pure" APCO P25 signal.
