+# OpenHamClock WSJT-X Relay Agent
+
+Bridges your local WSJT-X instance to a remote OpenHamClock server.
+
+WSJT-X sends decoded FT8/FT4/JT65/WSPR messages via UDP, which only works on the local network. This relay agent captures those UDP packets on your machine and forwards them to your cloud-hosted OpenHamClock instance (e.g. openhamclock.com) over HTTPS.
+
+## How It Works
+
+```
+WSJT-X  ──UDP──►  relay.js (your PC)  ──HTTPS──►  openhamclock.com
+                   port 2237                        /api/wsjtx/relay
+```
+
+## Quick Start
+
+### 1. Get Your Relay Key
+
+On your OpenHamClock server, set the `WSJTX_RELAY_KEY` environment variable:
+
+```bash
+# In .env file or docker-compose environment:
+WSJTX_RELAY_KEY=your-secret-key-here
+```
+
+Pick any strong random string. This authenticates the relay so only your agent can push decodes to your server.
+
+### 2. Run the Relay
+
+On the machine running WSJT-X:
+
+```bash
+# Download just this folder (or copy it from the repo)
+node relay.js --url https://openhamclock.com --key your-secret-key-here
+```
+
+Or with environment variables:
+
+```bash
+export OPENHAMCLOCK_URL=https://openhamclock.com
+export RELAY_KEY=your-secret-key-here
+node relay.js
+```
+
+### 3. Configure WSJT-X
+
+In WSJT-X:
+
+1. Go to **Settings → Reporting**
+2. Under **UDP Server**:
+   - Address: `127.0.0.1`
+   - Port: `2237`
+   - ☑ Accept UDP requests
+
+That's it. The relay will show decoded messages as they come in.
+
+## Requirements
+
+- **Node.js 14+** (no npm install needed — zero dependencies)
+- WSJT-X, JTDX, or any software that speaks the WSJT-X UDP protocol
+- Network access to your OpenHamClock server
+
+## Options
+
+| Flag | Env Variable | Default | Description |
+|------|-------------|---------|-------------|
+| `--url` | `OPENHAMCLOCK_URL` | — | Server URL (required) |
+| `--key` | `RELAY_KEY` | — | Auth key (required) |
+| `--port` | `WSJTX_UDP_PORT` | `2237` | Local UDP port |
+| `--interval` | `BATCH_INTERVAL` | `2000` | Batch send interval (ms) |
+| `--verbose` | `VERBOSE=true` | off | Show all decoded messages |
+
+## Running as a Service
+
+### Linux (systemd)
+
+```ini
+# /etc/systemd/system/wsjtx-relay.service
+[Unit]
+Description=OpenHamClock WSJT-X Relay
+After=network.target
+
+[Service]
+ExecStart=/usr/bin/node /path/to/relay.js
+Environment=OPENHAMCLOCK_URL=https://openhamclock.com
+Environment=RELAY_KEY=your-secret-key
+Restart=always
+RestartSec=5
+User=your-username
+
+[Install]
+WantedBy=multi-user.target
+```
+
+```bash
+sudo systemctl enable --now wsjtx-relay
+```
+
+### Windows (Task Scheduler)
+
+Create a batch file `start-relay.bat`:
+```batch
+@echo off
+set OPENHAMCLOCK_URL=https://openhamclock.com
+set RELAY_KEY=your-secret-key
+node C:\path\to\relay.js
+```
+
+Add it to Task Scheduler to run at login.
+
+## Troubleshooting
+
+**Port already in use**: Another program is listening on 2237. Use `--port 2238` and update WSJT-X to match.
+
+**Authentication failed**: Double-check that `WSJTX_RELAY_KEY` in your server .env matches the `--key` you're passing to the relay.
+
+**Connection errors**: The relay automatically retries with backoff. Check that your server URL is correct and accessible.
+
+**No decodes showing**: Make sure WSJT-X is set to UDP address `127.0.0.1` port `2237`, and that the "Accept UDP requests" checkbox is enabled.

+/**
+ * OpenHamClock WSJT-X Relay Agent
+ * 
+ * Captures WSJT-X UDP datagrams on your local machine and relays
+ * decoded messages to a remote OpenHamClock instance (e.g. openhamclock.com).
+ * 
+ * WSJT-X sends UDP only on the local network — this bridge lets your
+ * cloud-hosted dashboard see your decodes in real time.
+ * 
+ * Zero dependencies — uses only Node.js built-in modules.
+ * 
+ * Usage:
+ *   node relay.js --url https://openhamclock.com --key YOUR_RELAY_KEY
+ *   
+ *   Or with environment variables:
+ *   OPENHAMCLOCK_URL=https://openhamclock.com RELAY_KEY=abc123 node relay.js
+ * 
+ * In WSJT-X: Settings → Reporting → UDP Server
+ *   Address: 127.0.0.1   Port: 2237
