New M-E-P TG on the MSP Analog TRS - 39155

Had my 15X on ID Scan this morning,Ive been catching traffic on TG 39155, from the callsigns, CHARLIE 56 ,MIKE 60 its coming up as MA Enviro PD. MIKE being Coastal and CHARLIE being Inland..first TX I heard was referring to a hunter complaint in Sutton MA(CHARLIE Unit) then another hunter being run through disp by a MIKE unit..Not sure where..

Possibly 39155 is a new TG,I checked ScanNE and RRDB,both COmmonwealthP25 and MSP systems and its not coming back as a listed tg

Control/Dispatch is giving a RID of 31903,,

Based on the number, I think that's a patch of some sort. Regular talk groups are multiples of 16, patches are numbers not multiples of 16. There is a list somewhere that tells what the specific patches are, but I don't have access to it.

Someone will probably come along and tell us. ECPS92 is pretty well conversant on those things.

thought my ears were burning.

Yes
39155 = 98f3 in Hex
the 3 bit is a Patch between TG's

There is a patch between 39152 (MEP 1) and 39120 (MEP 4). Channel 4 is used in the digital system and channel 1 on the analog.
