There's a Beaver PA listed as 107.2 and I did hear something about West Mayfield.
Nice Catch.
155.01 151.4 is Beaver County PA North Police Dispatch. That would include West Mayfield, just north of Beaver Falls.
This system has a unique sound to it that should verify your QSO.
The mobiles use a fast DTMF burst as a data ID. If you heard that DTMF sound, you got it the QSO.
Yesterday was active at my place in Pittsburgh, I thought I heard EMS traffic on 155.955 at an address in Cleveland. That is about half way to your place.
Never heard anything on 155.37, I guess that is about expired, a shame.
VHF public safety is not as popular these days, and high power post re-banding is extinct, a shame for hobbyists.
Where are you? Grand Rapids? VHF is going away in favor of the state system, correct? Another one bites the dust.
