K0IRO DMR Repeater Information
Our DMR repeater is now fully online and available for use. We are excited to bring expanded
digital voice capabilities to the Iowa Radio Operators community and look forward to its
continued growth and activity on the air.
The repeater is fully integrated with our monitoring tools. Operators can
view live activity, callsigns, talkgroups, signal quality, and system performance through our
Digital Last Heard dashboard. This provides excellent visibility into repeater usage and helps
operators understand current traffic and system behavior.
You can access the live dashboard here:
