Greetings everyone!

Recently, I've been doing some "Talkgroup identification listening" on the MUD trunking system.

The trunking system has four sites represented by licenses WPTZ624 (Murray, Nashville) and WPTZ625 (Omaha, Gretna) which are located on the corresponding OPPD towers.

Looking at the FCC database, one also finds license WPYZ529 (Omaha, Gretna) and WPYZ530 (Murray, Nashville) which are connected to 857.2875 at each site.

Is 857.2875 some sort of conventional emergency channel, in case the TRS experiences a meltdown of some sort?

I see/hear the following...

E6-856.7625
FB-857.2875 (this one was just used by a dispatcher to respond to field unit)
10E-857.7625
136-858.7625
15E-859.7625 (control channel for now)

As I just heard FB used for a normal response to a field unit, I don't think and certainly don't know if it's an emer channel. I think maybe there's more to this system than we think? I'm logging in with UTrunker and listening and writing notes, so I may know/think more later...
