Over the weekend, several Norman talkgroups appeared different from normal. This was due to "patching" during the Midieval Festival .

Norman Fire was patched to local Mutual Aid 7C (talkgroup 57488). This made all Norman Fire traffic appear to be on 57488 while 48880 was silent. This has to do with the way the patch is set up and how a scanner interprets the patch.

The Norman Fire patch was set up with the LMA talkgroup as the master and the normal fire dispatch talkgroup as the subordinate (don'tcha just love UniTrunker?). So the scanner only "sees" the master talkgroup and not the subordinate. However the Norman Fire radios are still on their normal talkgroup. This allows the system to patch multiple talkgroups without using multiple voice channels.

Noman uses Local Mutual Aid channels to allow radios that are not normally able to use certain talkgroups to link to them. LMA talkgroups are used extensively during OU football games.

Was the Medieval Security allowed to carry the state-of-the-art trunking talk-to-anyone-the-state-that-I-want-to-talk-to 800 MHz hand-held radios for communication, or were they required to use something Medieval, like VHF analog hand-helds? Or flint-and-steel and a blanket for smokesignals.

So that's how that works. Thanks.

LMA 7A is used routinely by NFD and OUPD when they respond to fire alarms on the OU campus.
