Dispatch Channels for Windham, NH Police and Fire.
(155.6025MHz & 154.175MHz)
This feed received from 154.175MHz (FD) and 155.6025MHz (PD) at an attitude of 30ft above ground level (about 305ft), 1 mile from the stations. With my antenna I estimate a 2 mile range in a straight line for Base station/Vehicle radios (FD) which will cover most of the town clearly except for the northwest area which could be spotty. Humm that is heard with Fire Alarm is on the end of the dispatch center and can not be fixed on my end. Also the Digital sounds that are heard with the Police Dept radios are heard when the signal gets spotty (similar to standard NFM static).
