I received a steady alert today on my RX-65 in Tech mode with an alert of 33.700 it was 100MHz off of the well-known 33.8 of the BEE III with POP mode. As far as I know, I don't believe we have POP mode in Florida yet but I have received POP alerts then immediately received a Ka signal after. Also, when driving home about 100 feet from my apartment an LEO was parked on a driveway hidden behind a building wall and I saw him and applied the brakes (I was going about 33-34mph in a 30 anyways ) and immediately then my radar detector displays POP and then silences itself. No other traffic nearby and I drive this route every day (being my way home) and it never falses.
Is it possible for the MPH to be present in Florida, or for it to drify 100MHz off? Most frequencies I get are 34.750 or 35.5 in the next county.
What could be the explanation for the apparent "POP" use?
