I became active using DMR in 2016 after picking up a TYT-MD380 at the Dayton Hamvention. This mode was fairly new to hams at the time so it was a steep learning curve for me. There wasn’t much information published at that time. Since that time I have acquired 5 DMR HTs, a mobile, two openSPOTs, a DVMEGA/Pi-Star on RPi 3 w/two Nextion displays, ZUMspot/Pi-Star on RPi 3 w/ three Nextion displays, and a ZUMspot/Pi-Star on RPi Zero.
