@nrao_hamradio i'd try to stop by! i'm currently working on emergency response plans for the household and i've designed a GMRS system and configured all the radios in the house to have the same channel IDs so you can just pick up one and go.
and four of them have location services (3 #gmrspro HTs and 1 vero #VRN76 that can give you the location of other radios in your group. the Vero even does APRS but be careful with that cuz it's not well implemented yet.
