Supposedly I can use my BTech GMRS 50 pro mobile radio with a plugin to run an ATAK setup.
Nice... I saw that, on YouTube. I'm using a raspberry pi 4 with a wifi halow hat, and openmanet. Range is likely shorter than your btech, but I'm able to extend range with other nearby units, as well as share video feeds, use meshtastic/MeshCore, use reticulum, and mumble for ptt. I really should do some nostr only videos on it. 🤔
