What unit numbers do they identify with? That might give a clue. Lancaster City units start out with "42" as their agency designator. For instance Forty Two Nine is a supervisor...... CTCSS Tone is 71.9
Yes i'm up high on the side of a mountain. But then again there are large hills all around. I can pick up Exeter PD, Berks county on 155.0700 crystal clear and they are 40 miles away. But back to the frequency in question 154.8750 I just started picking it up several weeks ago. It's possibly about 60+ miles away and maybe im picking it up through a repeater on a nearby mountain.
