Channel
|
A channel usually encompasses the repeater frequency, offset, color code, and a talk group. Sometimes other
settings are also defined in a channel. Typically there is only one talk group in a channel. For analog channels
(repeater or simplex) it has the usual data—offset, CTCSS/PL tone, etc.
|
If a repeater supports 10 talk
groups, then you’d typically need
10 channels for that repeater—one for each TG
|
Zone
|
A zone is a group of channels (analog, digital, or both). The user has flexibility in how they define zones. Some common organizations of zones can be:
- A set of analog channels (such as “ACS UHF" repeaters)
- A DMR repeater, with a channel for each talk group supported by that repeater
- A talk group, with a channel for each nearby repeater that supports the talk group
|
Zones are a very useful way to
personalize the configuration of a
DMR radio.

DMR ID
|
DMR requires a numerical identifier, which is transmitted automatically as part a data packet whenever you key up. The ID generally corresponds to a user, so you can use the same ID on multiple radios.

Get your DMR ID at radioid.net.

Code Plug
|
A code plug is a configuration file for a radio. It contains everything needed to get the radio up and running on
repeaters, hotspot, etc. DMR enthusiasts often share and modify code plugs to help build up good configurations
for an area, for a given radio model, etc.
Because they can be customized, many users will write different code plugs to their radios depending on what
they’re doing, e.g. if they are traveling to a different part of the country, they can use a code plug with repeaters
in that area, without having to have those repeaters permanently using up channel space on their radio.

Most DMR rigs are very
challenging, or even impossible, to
program via the front panel. Use
programming software to make or
modify code plugs.
