New Petersburg FCI Phase 1/Phase 2 TRS

W4UVV · Jan 27, 2015

When programing my 536 I discovered the Petersburg FCI has a new P25 Phase 1/Phase 2 trs. Normally there are frequent comms. Using one of my DMR decode systems for testing I found the old 5 frequencies had been abandoned and so far I have identified 4 of possibly 5 new frequencies. As sometimes happens Pro96Com works and at other times it won't work with my desktop. Today was one of the times it wouldn't work. I try again later with another computer.

I used my DMR Decode systems and DSD 1.6 and DSD PLUS software for testing.

The new trs monitored attributes are:

SYS ID = 6DA

407.4125 mhz. = Control Channel & voice NACS = 6D0 & 7D0
408.0125 mhz. = Voice NAC = 6D0
408.6125 mhz. = Voice NAC = 6D0
409.0125 mhz. = Voice NAC = 6D0
Unknown Freq. = Voice NAC = 6D0

System Type = Either "P25 Standard" or "T2 XDMA"

The 400 mhz. custom edited table still is required.

All talkgroups appear to be new.

FYI approximately 1,540 federal inmates currently are housed in five housing units called "Pods". Each Pod is named as follows: Alpha, Bravo, Charlie, Delta and Echo. Each Pod is further subdivided into four sections as follows: North, South, East and West. A TG 2 comm example is: "Release Charlie West for chow". A TG 5 comm example is "Can you lower the temperature in the dining room?"

Here's some additional trs info from Pro96Com and off air monitoring::

Correct frequencies configuration:

407.4125 mhz. = Control Channel
408.0125 mhz. = Voice
408.3250 mhz. = Voice
408.6125 mhz = Voice
409.0125 mhz. = Voice

Talkgroups heard so far: 1,2,3,4,5,6,7,12,16,26,29,30,31,32,33,34,36,40,48,59 and 60
