Most of those rigs I’ve seen have an NJICS radio, a VHF and a UHF which have pretty much every local municipality’s channels in them. (I don’t recall seeing any with the Bergen County TRS). I did notice that whenever an EMT or employee needed to speak with somebody (a conversation which may have been used on a “tac” channel) , they would just use a cellphone. I never saw any channels specifically devoted to those hospitals in their rigs besides the MICCOM channels.
