This summer I posted an inquiry as to where 501.5875 is with limited results. I am picking it up while I monitor in Atlantic County. It is coming up as a P25 and sounds like it might be in southeastern PA.
Yes, I had it as Garfield in my scanner originally. But I knew Garfield was not P25, that it was not likely that I would pick it up in Atlantic County and based on the traffic it was a PD in southeastern PA. Thanks and now my mystery has been solved thru a great RR member!
