Last night around 8:45 PM I did a search in the lowband range (25-54) to see if anything was skipping. I came across 42.92 and turned CTCSS on to find a 173.8 PL tone. It sounded like police / highway patrol talk. Any idea what this was? I received it from down the street from my house in Lansdowne, PA with my Pro 97 using the Radio Shack telescoping antenna.
