Okay I'm pretty sure it's Bucks County transportation, Newtown and Points North where Levittown and Bensalem cut off.. with one other base for the far north end of the county. Three frequencies and three bases.
For me this is just a preliminary investigation and I'm very thankful to those who have known me for many years and provide me with information..
I give you a lot of credit for pinning down these kinds of comms..
My focus lately has been Federal encrypted frequencies, you might want to try it.. every morning, across the country, busy as hell.. keep track of the Simplex tac frequencies, they might even be in the clear😆... in your neighborhood LOL.
