Hello All, In SE Ohio we have a semi-private ambulance company. It is Southeast Ohio Emergency Medical Service (SEOEMS). They recently started using MARCS for their Admin Staff to communicate on. Mostly, their traffic is just BS. I'd like to lock out all of their TG's, but, I so far, haven't been able to ID all of what they're using. I've tried to locate them listed in the RR database, but, so don't see them their either....Any suggestions? I'm trying to catch them talking to get the displayed TG to note it, but, haven't made it so far !!! Thanks, Steve/Gallia 911/KB8FAR
