Check the Data bases in these towns to find your specific frequencies.
Each Regional Dispatch center operates on various frequencies.
For example TN operates on 33.44 as the primary operating frequency. Over time as departments purchase UHF portables they construct UHF to Lowband Cross band repeaters in their town for improved coverage. There are several 33.44 cross band repeaters in operation.
Also QV operates medical calls on 33.88 and Fires on 33.90. They also have two UHF frequencies which the operate calls on.
What you need to do is find the repeaters nearest to your location and tune them in.
Station WA dispatches for the City of Putnam Fire Department and for Putnam EMS. They dispatch via 33.80. Dispatch is also simulcast on 154.355 156.7 which is Putnam Fire and 155.295 146.2 which is Putnam EMS. Putnam Fire then operates on 154.355 and can use a cross band repeater if they go mutual aid to a QV town. Putnam EMS operates on 155.295 all the time. If the call is in East Putnam (part of their jurisdiction but a QV town) then they also operate on whatever QV assigns them to.
