NJ has 2 of their own.
Arizona has an additional one of its own, as well.
8TAC95 853.0375 aka AZ TAC 5
Other states may also have their own 8TACs.
Also take note, although Maricopa County here has a Big M Type IIi 800 MHz trunked system, deputies like to use VTAC12 as a car-to-car chit-chat channel.
I've heard AzDOT employees also using a VTAC for car-to-car comms after a particularly heavy rain event as they were checking the freeway underpasses for flooding, instead of the AZWIN 700 MHz P25 trunked system.
I've also heard encryption on 7TAC73 and on one of the 700 MHz national low power itinerant channels. I have no idea as to who those users were.
You never know who you may hear where, so program in all of the interoperability channels.
