I'm not trying to sound like an alarmist here but, twice this week I've encountered what appears to be moving radar in PA. The first encounter was on Rte. 80 between the two Bloomsburg exits. (Rte.42 and Lightstreet) My X50 sounded an IO type alert and displayed 24.158. I did not think to much of it until the signal went rapidly to full alert again. I decided to slow down at this point as I was going 80. I then spotted an unmarked blue CVP with tinted windows.(He was going westbound, I was EB) Could not see the antenna inside the car and I did not see the barrel type unit on the side window.
Today's run in was on I81 NB between Harford and Gibson. Again I was motoring briskly alon when suddenly Val goes full alert on KA. This time I really slowed down to the psl. The signal faded then suddenly went full alert again. I spotted an unmarked white CVP (SB) and this time I saw an antenna mounted center of the dash. The strange thing is that the face of the antenna was black instead of the usual (for my area anyway) white face. Incidentally, Val correctly tracked the cruiser as it passed by. Any of you PA guys come across any of this? Sorry to be so long winded, but this could become an "inconvience". Scott
