In the good old days, before all digital, there were devices that could detect local oscillators and the like in concealed "tape recorders" and the like that didn't broadcast. These detectors were used some places.
I am mostly aware of the RF coils and tuning coils and receive/transmission for broadcast. I am pretty sure those still exist even in the all digital world, but if someone knows different, let me know.
In fact thinking about it, I am not sure what the status of oscillators are in the modern digital world.
If I get a chance, I will look it up.
