> It's also the only state to prohibit radar detectors
Which is arguably outside of the state’s jurisdiction. Only the FCC has the authority to regulate the airwaves and specifically transmitters and receivers.
I bet that cop’s radar gun has an FCC sticker on it.
All radio receivers have local oscillators built into their receiving circuitry that actually transmits energy that can be detected by specialized receivers.
Not only are there radar detector detectors, but then there are radar detector detector detectors, and radar detector detector detector detectors. A hilarious arms race.

All efficient radio receivers....
It is possible to build radio receivers without such. I built a crystal set as a child that could power an air piece without a battery using only the AM signal.
Not so much with modern ADC based receivers, it is possible that the only oscillator is at a fixed frequency and the only “tuning” happens in a computer.
