On my SDS100, the local fire department will dispatch units via a patch call to Fire Dispatch as well as the Paging talkgroup
You might try adding the one you want again so it appears twice in your programming. Get your scanner to scan the one you want twice giving you a two to one advantage the scanner will stop and monitor on the wanted one.
Applying Priority DND (do not disturb) to first the wanted and second the unwanted will not work if the scanner sees the unwanted one first. But you might try it.
The same patched announcement goes out on the Fire Dispatch TG and the Fire Pager TG at the same time on the same site you are monitoring so it doesn't matter which TG you are monitoring, you will be hearing the same thing from both TG's? And what exactly are the issue with it that you want to avoid?
Setting a prio to TG are only active when a TG are in idle state when no one are transmitting and the scanner are back at the control channel. You can't enter the same TG number twice in a system. When the scanner reads the favorite list it stores all programmed TG numbers in a sorted list and when it decodes a TG from the control channel it goes thru the list to find that TG. It depends on when the scanner decodes the control channel and when the TG appears in the data stream, if it starts to decode just when one TG have already been sent and the scanner picks up the second one, or if the patch sometimes activates the two TG's in different order.
If you have site hold On and avoid all departments and create a new one with only those two TG's do you see if it always picks one of the TG numbers first? (None of the prio functions active when testing, DND, WX)
There's really no way to force one TG to have priority over another already active one, that will take preemptive priority to be used that needs it to be programmed by the system administrator to that TG to be sent out on the voice channel, and Uniden to add that feature in the scanner firmware, that we have asked to be done in the wish list to Uniden.
