Programming the W4XI DMR Repeater Information

First, you need a DMR ID - get it at radioid.net - this will be your "Radio ID" when you program the radio.

Receive Frequency: 443.825
Transmit Frequency: 448.825 (+5 MHz offset)
Color Code (CC): 1

For Transmit Admit, set "Color Code Free" - this will have different names in different radio programming software, but the gist of it is this: if the repeater is active due to another user, even if you don't hear that user, your radio should refuse to transmit.

If you have a radio capable of encryption or voice inversion (scrambling), make sure they are not enabled (these are either outright illegal or of questionable legality for amateur radio usage).

For talkgroups and timeslot usage, the general rule is that timeslot 1 is for wide-area communications while timeslot 2 is for smaller area communications.

Recommended talkgroups to include:

Talkgroup (TG)
Time Slot (TS)

There are lots of others; for a full list, see the AmComm TalkGroups page. Keep in mind that all of those should use timeslot 1.

The only "on all the time" talkgroups on the W4XI repeater are 1, 2, and 3101. Others are what's known as "dynamic" talkgroups; these are temporarily activated with a PTT press and automatically deactivate after 15 minutes of inactivity.

Our goal is to keep timeslot 2 for mostly local (or locally relevant) traffic, which is why there aren't any static linked talkgroups on TS2. The statewide Alabama talkgroup (3101) is statically linked on timeslot 1, and we strongly prefer that any other wide-area talkgroups (e.g. other states, worldwide, etcetera) or even talkgroups targeting other regions of the state (e.g. North Alabama) be connected dynamically on timeslot 1.
