dmr-bridge
Infrastructure deployment for ham radio tools.
What is this?
This is a Docker container that bridges a USRP client to the BrandMeister DMR network. It allows you to use a USRP client like DVSwitch's USRP_Client to run netops on BrandMeister. It uses the following:
dmr-bridge was forked from hsoj's hamenv. It was changed in the following ways (among others):
- Removed support for emulated MD380 decoding
- Added (required) support for a ThumbDV (or similar) hardware AMBE3000 decoder
- Consolidated into a single container
- Removed much of the configuration that doesn't matter to the final functionality including:
- Fixed some bugs
Usage
For easy setup, you can use scripts/build_and_run.sh. Otherwise, the
container uses the following environment variables:

| DMR repeater | REPEATER_ID |
No | ${CALLSIGN}01 |
| Latitude | LATITUDE |
No | 0 |
| Longitude | LONGITUDE |

If you need to set a hotspot password, do so at the BrandMeister self-care page.
Client
I maintain a fork of DVSwitch's USRP_Client that allows devices that are both input and output (like audio interfaces) to function. I plan to remove that fork when the relevant patch hits the upstream.
