DynRgrp is Dynamic Regroup. Essentially a subscriber can select this talkgroup and it allows the dispatch center to temporarily 'reprogram' the talkgroup to do whatever they need to accomplish. I've never seen or heard it used in Morris County. There is no specific talkgroup, in the radio its Dyn.
I've never heard ALCOMMON used. The TGID is DEC 2305 HEX 901.
FG1-4 EVAC are the Fireground channel that the subscriber switches to in emergency mode. The radio will revert to the normal fireground once the emergency is cancelled. These are the same frequency as the non emergency channels.
ALL-IOP I've not heard this used before either. It's a conventional channel. 453.62500
Police Direct and Police Car to Car are talkgroups police can use when they need to talk to each other and don't need county to correspond. I've heard it used for traffic details and the like. I believe they are recorded talkgroups unlike a fireground which is not repeated to the commcenter. Police Direct is HEX 115 DEC 277. Police Car to Car I have two possible TGID's I have not confirmed them. First is HEX 125 DEC 293, second is HEX 325 DEC 805.
I'm not going to submit those talkgroups because I am unsure of their status, if someone has more information on them please submit it. If any of my information is wrong above please correct me.
