Yet the PD i work for a cop can be 5 miles away and i can barely make him out.It amazes me at how clear the dispatchers come in down here in jersey.They do have towers on Sparta Mountain and Little Ferry I beleive they are transmitters. However i could be wrong by calling them transmitters. I do know however that going from Coop to whatever tower they go over phone wires then up to the tower. When the NYSW needed a new radio system in the early 90's my father helped them install it. He even had the "tough" task of going for a cab ride and testing the radios too! If more details are wanted I could probaly ask him next time we talk.
