Radio Configuration
We have created a page to help with the registration and setup of your D-Star radio. You can find it here: https://mawcg.org/connecting-to-our-d-star-repeaters/
These 3 settings are required for D-star to work properly. Here is what each of these are:
D-Star
- URCALL: The command or linking / routing information
- CQCQCQ: For talking on the local repeater and/or going out to the connected reflector
- REFxxxL: command to link the local repeater to REFxxx.
- I: Get info like where the repeater is connected, etc
- U: Unlink local repeater from wherever it is connected to.
- CALL1: This is the callsign of the repeater and module that you are trying to talk to.
- There are some special formatting needed for this:
- Callsign must be 6 characters long. If you callsign is not 6 characters long, fill up the additional characters with spaces.
- There must be a single space between the callsign and module.
- The module is a single uppercase character
- Modules are in most if not all cases:
- A – 1.2 Ghz Voice
- B – 440 Mhz Voice
- C – 144 Mhz Voice
- There are some special formatting needed for this:
- CALL2: This is the callsign of the gateway you are trying to connect through. In most cases the callsign of the gateway is the same as the repeater.
- Similarly to CALL1 this has the same special format of 6 characters for callsign, a space and a single character that is always G for gateway.

Related FAQs
D-Star
We changed the call sign for the D-Star repeater KB3YBH to W3FDK. In that process, we had to rebuild the gateway from scratch. Because you have to build from scratch, all of our previous registrations are no longer in the system and are not able to be changed.
Your Options
Your options are limited. Your callsign is still registered in the central system so you cannot re-register at a different gateway.
If you need to make changes you have to contact the D-star folks and have them remove your call sign and then re-register. We will update this FAQ with contact details once we know who they are.
This is an unfortunate consequence of changing a call sign for a D-Star repeater, there is not way to import the old database of users into a new call sign because you are already registered in the central database under the old call sign.
Some D-Star Links

General Radio Questions
The term Codeplug has been popularized in recent years because of the rise of DMR, a commercial digital voice mode that has been adapted to Ham Radio.
Put simply, it is the config file that can be used to program a radio. Some people use Chirp or other software to program their radio. A codeplug is simply that config file.
The term originated from Motorola from back in the day when there was a physical “plug” that was used to setup the radio. DMR was popularized by Motorola and the term Codeplug is common among Motorola equipment.
Since DMR has become popular people have been using the term Codeplug to represent any radio config.
