154.710 is definitely Moore PD.
451.850 is the primary channel for Leon's LTR system.
You're probably hearing the unidentified security patrol
company on this channel. They have two active channels,
one that they refer to as the OKC channel (on the OKC
site) and the other that they refer to as the Edmond
channel (on the Edmond site). They're fairly active all
night long. I haven't been able to figure out who they
are yet.
Actually, there are several security companies on this system. IIRC, Leon explained it as he uses the Edmond and OKC tower, and has five channels basically. When one company keys up, it stops on that channel and only the other radios with the same id can receive. It is constantly moving channels.
As far as I know, Tam and Harris Security, Corporate Security Inc (OKC CSI), and like 4 others use him. I remember programming that in, but then realizing it was a trunked system and the scanner being used would not do trunked progoramming. So we could occasionally hear outgoing, but not incoming.
Does this make sense?
