# 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:
|
|
|
|
```bash
|
|
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:
|
|
|
|
```bash
|
|
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.
