If you're at all interested in a DMR hotspot, go read this link put together by my friend Jarrod, KQ4TAY - https://jarrodandrews.com/construct-a-raspberry-pi-wpsd-hotspot/. And if you're still trying to figure out DMR, go read this link: https://manual.wpsd.radio/zero_hero/anytone_878/. I'll come back and post pictures and more later, but I like the DMR hotspot idea so much, I'm gonna build two of the raspberry pi devices - one for the house and one for the truck. I'll probably program the one in the truck to use the Starlink as a primary and the cell phone as a secondary (as I don't always have the Starlink powered up).
