Echo (playback)
What it is
Echo records incoming group voice and plays it back on TG 9990. It runs as a PEER process that connects to the ECHO master on the main peer server (TG 9990 bridge).
The playback runtime is part of adn-server; run adn-server.py --echo with minimal adn-echo.yaml.
Configuration
Use a small separate YAML — only what the PEER needs to attach to ECHO in adn-server.yaml:
| Field | Role |
|---|---|
GLOBAL.SERVER_ID |
Echo network identity (often 9990) |
LOGGER |
Log file (optional but recommended) |
SYSTEMS.ECHO |
MODE: PEER, local IP/PORT, MASTER_IP/MASTER_PORT, PASSPHRASE, RADIO_ID, CALLSIGN, OPTIONS |
No PROXY, ALIASES, or REPORTS required. MASTER_PORT and PASSPHRASE must match ECHO on the main server.
- Copy
adn-echo.example.yaml→adn-echo.yaml(not committed). - Run:
python adn-server.py --echo -c adn-echo.yaml
Typical production: separate systemd unit (see examples/systemd/adn-echo.service in the repo), same binary:
sudo cp examples/systemd/adn-echo.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now adn-echo
Relation to TG 9990
The main server exposes an ECHO master on TG 9990 for the echo bridge. The standalone echo service is a separate process with its own config that connects to that master.
