I will add majority of counties are going to a setup like this:
Page out on the old countywide repeater or main.
Once done there will be region repeaters specific to that area of county where units or that area/dept will key up on and have their comms there keeping the county wide Channel free for dispatch to page others or give detailed information over air. The channel will be set as a priority in scan. No more setting local law as your second primary some end up doing. You'll have the page channel then respective dispatch repeater channels for each district in a county that dispatch can reply on if needed.
Kind of like how dona ana and Eddy are doing now.
Then from the second repeater once on scene unit tacs will be assigned in simplex. Most will have tacs 1 to 8 (6being more common for most around in the counties) for fireground operating.
This is the new scheme everyone is going to and most have been guarding the new setups. P25 for many is in works on it all as well on vhf.
I would start by scanning the mobile frequencies thst aren't repeated for the tacs they have listed in fcc.
The new scheme calls for all to have for sure the vhf interop plan and or 700 interops if capable. A programming scheme of only having the counties touching your countg border programmed in is the latest way its being done everywhere. Not every single county as some would do in past. Vtac 17 and couple others are go to with most for mutual aide replies out of area now. Others are slowly getting there setups to this.
Before I start down my next rabbit hole,,,,,, does anyone have a recent (year or two old) listing of the San Juan County Fire TAC/FIRE channels? The list in the RRDB is not accurate/complete, IMO. I found a topic from 2013 with a list that was what I am looking for but this too is not accurate today.

In advance, thanks.
