Last night around 4:30 am I was searching the 460 MHz police band. Not really looking for anything but just wanting to hear a variety of departments that use that band. The scanner was in my car w/ a high-gain VHF/UHF mobile-mount antenna. I started picking up what sounded like 28/29 checks thru a dispatcher on 460.4125. That scanner doesn't decode tones, so I didn't see if it had one. I really didn't think anything of it at the time because I figured it was probably some college PD or something. Once I got to work and looked it up on RadioReference, I was surprised to find it is the OCSO tactical/shared freq. I had a good mobile antenna, but even w/ that antenna there's no way those comms were simplex that I can tell. It definately sounded like it was thru a repeater. I'll give a listen tonight and see if they are using the freq again. Does anyone know anything about this freq and if it is indeed a repeater? I've never heard anything on it before. And it's listed for Bomb Squad/Tactical (Shared).
