Also, some models in years past were taken off the market due to the FCC so they defintely have a hand in it. I will tell you that my Escort Radar Detector is no joke. My wife was miffed when she saw the CC statement come in. Ever since I got that 73/65 ticket on the turnpike I said never again.......
I have friends with the Portsmouth and Greenland PDs and they would tell you first hand that my Escort works against their car based units. I honestly have not spent the time digging into vagaries of how it works but now I have renewed interest.
