On a motorcycle board one of the riders has two radar detectors; one is a newer model (unknown) and the other is an old Trapshooter "Liberty" model. The person claims that when moving radar is kept in "Standby" mode, the vehicle speed radar is kept on, and his old RDD picks it up, whereas the newer model didn't.
The cops in FL (where he lives) leave the radar on standby so they can quickly punch it on if needed.
I know there are two signals used, one to measure the cop car's speed and one to measure the targeted vehicle's speed. I was thinking that a modern RDD would look for both frequencies. Any ideas?
