If Southwest Mutual Aid out of Keene is still controlling their simulcast with low band, 33.78 is the frequency to hear dispatch.
NH Homeland Security & Emergency Management is still using 46.58 for now around the Seacoast for the Seabrook nuclear plant drills.
The Milford area was in the process of moving everything from 33.64 to VHF frequencies. I don't know if any are left.
My job has one Low Band / cross band transmitter on a hardly used parks repeater on 31.90 in Milan. If ya ever hear anyone on that, it's probably me testing LOL.
Other than maybe a business or two, or whoever I missed, that's about it.
