Curt,
I'm no engineer but in extensive research on YouTube and other viable sources of information, I understand that radio waves take on some type of parabolic curve which distorts the signal strength once the speeds get above 135 MPH. This is accentuated by large, flat hoods with more reflective tendancies as seen on V-8 powered vehicles. That's why the NASCAR racers have that "garbled" tone to them when talking to their pit crews. So any testing you do, for the sake of our communities, should be conclusive that there are no interruptions in radio frequencies by our police officers!
