Using DMR
DMR-MARC is an organization which requires registration and thus allows you access to their group of DMR ham radio repeaters. Although there are alternatives, this seems to be the largest and most widely known way to get on the air with your MotoTRBO or other DMR compatible ham radio. Consider DMR-MARC the current "master listing" of DMR repeaters worldwide.
All radios on ham radio DMR networks require a unique Subscriber ID. Each radio has a unique Subscriber ID. A single ham operator may have multiple DMR radios, each having a subscriber ID, thus allowing one ham to have multiple subscriber IDs.
Registration:
The DMR radio needs to be programmed with data to allow access onto this DMR network.
You can use one of the various online DMR repeater network maps to locate information for the repeaters in your area.
