As far as specifically tracking someone RECEIVING radio frequencies,
I'm not familiar with any piece of equipment capable of doing that.

If such a device existed, I have no idea how it would differentiate
someone's AM/FM stereo, wireless router, baby monitor, coordless
phone,or garage door opener from a scanner. (Yes, I know, some of
them transmit.. and that can be detected.. I mean from the "receiving"
point of view, for example.)

By the frequency of the local oscillator, but that's very iffy as
legal evidence.

Well, it doesn't seem too iffy in Virginia and D.C. They use devices (VG2
detectors) that pick up local oscillator frequencies in radar detectors, and
have no problem using it for legal evidence...
