do you know who uses radio id 8309011 with nac 293? thanks ...167.675 its simplex or repeater input, always the same 3 bars of signal strength from my house everyday. encrypted
167.x MHz with a 167 NAC (though you didn't specify the nac, it's likely for that freq) is FBI frequencies. 8xxxxxx is US Marshals as Kenny said, and they do a lot of interop onto FBI freqs and vice versa.
