At the risk of sounding like I need the tin foil hat, I'm gonna throw this out there: Myself and my workmate in SC covered the whole state between us. As a rule we spent our road time talking on the phone to each other and started noticing that when we would pass cops on the interstates with someone pulled over, we would lose signal and drop the call. Originally we just attributed it to sucky cell service here, but began noticing the vicinity of a cop with blue lights on when it happened. We've both moved on from that job, but I bring it up because he called me today to tell me about passing a Charleston city cop downtown with someone pulled over, and the call he was on to a customer dropped, and a block later he had full service again. We've discussed the possibility of cops using such technology to keep whomever they have pulled over from using their cell. Has anyone else encountered this? It's happened to me enough in the past 3 years that I'm considering putting the spectrum analyzer in the truck just to see.
