163.1000 100.0 vsp tac-1 alot of cross talk and used c/c, heard troopers even swear and use names of people and victims. its programed into there kenwood radios as they use motorola for there uhf comms. hear them in my area (upper conn. valley) marking cars for speed to other troopers. i havent heard much use in awhile on c/c (460.5000 118.8).
As stated, DMV units are primarily on the Troop channels for their given AOR. In addition, at weigh stations, I’ve heard them on all conceivable variations of the license for (whatever callsign is) 460.500, to include 465.500 P25 in the clear (don’t recall the NAC offhand), 460.500 CSQ, 465.500 118.8, etc.
The VHF informal use has moved away from the 163/168 federal interops over the past year. Almost all of that traffic is on 155.4875 CSQ now.
