Alright I do not have much experience with Trunked and Digital systems, so this is a learning experience for me.
SI Group is an industrial facility nearby me. I have found a listing of their FCC licensed freqs:
451.2875
451.3875
451.5375
452.625
456.2875
456.5375
457.625
463.7375
462.8125
464.6625
I have heard voice communications on at least 1 of the Freqs listen above and also have heard a noise on 463.8125 that sounds like a control channel. I recorded a brief clip of it: https://soundcloud.com/alex-kaczor-1/4638125a
Can anyone identify what type of system this is?
