Reliable and fast internet has enabled hams to link repeaters with ease.

Hams have embraced VHF digital modes and are making contacts around the world with this technology.

DMR

Colorado has a large DMR user base but before you are able to get on the DMR system you will need a DMR ID. You can get one at → RadioID.net.
Once you get an ID you can focus on programming your radio. The programming information for DMR radios is called a codeplug. Headsup! DMR radio programming can be difficult.
RMHam has a DMR network along the front range on their own microwave network. Their website has lots of information and sample codeplugs. Check it out at:

DStar

P25, NXDN, M17

These modes are used less in our area compared to Fusion and DMR. P25 and NXDN were both commercially developed. M17 is an open-source project by ham radio operators.
