RADIO advice sought for URBAN prepping

[CharlesHarris]

I don't know how agressive they are in UK with regard to locating unlicensed transmitters, but in the US our volunteer Auxiliary Communications Service routinely located weather balloons for NOAA, EPIRBs for the FAA and Coast Guard, as well as tracking taxicabs with unlicensed radios, capturing occilloscope traces of the transmitters which gave positive ID evidence which could be used in court. We were trained by the FCC and the police technology support unit and learned to use and operate their equipment. Computerized scanners, spectrum analyzers and directional antennas at the various public safety radio repeater sites could usually get a position fix on a targeted transmitter within 30 seconds and track it anywhere within a 100 km radius of Washington, DC, Baltimore or New York.
