DMRVA Talkgroup Matrix v2.4 updates posted 3/1/2025 for all supported radios.
At the July 19, 2024 RATS Membership Meeting, Steve Crow KG4PEQ delivered a presentation called "How to DMR." This presentation is targeted at new and inactive DMR users. It assumes the viewer has a DMR transceiver programmed with a RATS codeplug -- the processes of building codeplugs and programming radios are not included.
You can view the Zoom recording below, or access the presentation with supplemental slides.
You'll find additional resources on the RATS and DMRVA websites.
