**Python library for controlling Icom transceivers over LAN (UDP) or USB serial.**

Direct connection to your radio — no wfview, hamlib, or RS-BA1 required.

## Features

- ✅ **100% CI-V command coverage** — all 134 IC-7610 commands implemented (Epic #140, 2026-03-07)
- 🗂️ **Data-driven rig profiles** — add new radio support by writing a `.toml` file, no Python required ([guide](https://morozsm.github.io/icom-lan/guide/rig-profiles/))
- 📡 **Direct UDP connection** — LAN backend (UDP ports 50001/2/3), no intermediate software needed
- 🔌 **USB serial backend** — IC-7610 and IC-7300 USB CI-V + USB audio devices ([setup guide](https://morozsm.github.io/icom-lan/guide/ic7610-usb-setup/)); **automatic USB audio device resolution** for multi-radio setups via macOS IORegistry topology matching
- 🎛️ **Full CI-V command set** — frequency, mode, filter, power, meters, PTT, CW keying, VFO, split, ATT, PREAMP
- 🔍 **Unified discovery** — find radios on LAN and USB serial ports, deduplicated by identity
- 💻 **CLI tool** — `icom-lan status`, `icom-lan freq 14.074m`
- ⚡ **Async API** — built on asyncio for seamless integration
- 🚀 **Fast non-audio connect path** — CLI/status calls don't block on audio-port negotiation
- 🧠 **Commander queue** — wfview-style serialized command execution with pacing, retries, and dedupe
- 📊 **Scope/waterfall** — real-time spectrum data with callback API
- 🌐 **Built-in Web UI** — spectrum, waterfall, controls, meters, and audio in your browser (`icom-lan web`):
  - 🎛️ **Dual-receiver display** — MAIN and SUB receiver state (IC-7610)
  - 📻 **Band selector** — one-click band buttons (160m–10m)
  - 🔊 **Browser audio TX** — transmit from your microphone via Opus codec
  - 🎚️ **Full control panel** — AF/RF/Squelch sliders, NB/NR/DIGI-SEL/IP+ toggles, ATT/Preamp, VFO A/B
  - 📊 **Meters** — S-meter, SWR (color-coded), ALC, Power, Vd, Id
  - 🔄 **Live state sync** — HTTP polling at 200ms, no page refresh needed
- 🔊 **Virtual audio bridge** — route radio audio to BlackHole/Loopback for WSJT-X, fldigi, JS8Call (`icom-lan web --bridge "BlackHole 2ch"`)
- 📡 **DX cluster integration** — real-time spot overlays on the waterfall with click-to-tune (`icom-lan web --dx-cluster dxc.nc7j.com:7373 --callsign KN4KYD`)
- 🔌 **Hamlib NET rigctld server** — drop-in replacement for `rigctld`, works with WSJT-X, JS8Call, fldigi
- 🎛️ **Dual-receiver support** — MAIN/SUB via Command29 (IC-7610)
- 🎤 **Browser audio TX** — transmit from browser microphone
- 📡 **UDP relay proxy** — remote access via VPN/Tailscale
- 🔒 **Zero dependencies** — pure Python, stdlib only
- 📝 **Type-annotated** — full `py.typed` support

**USB Serial Backend**: Tested with IC-7610 and IC-7300. See [IC-7610 USB Serial Backend Setup Guide](https://morozsm.github.io/icom-lan/guide/ic7610-usb-setup/) for setup instructions.

## Installation

```bash
pip install icom-lan
```

From source:

```bash
git clone https://github.com/morozsm/icom-lan.git
cd icom-lan
pip install -e .
```

## Quick Start

### Python API

The recommended way to connect is **`create_radio`** with a backend config (LAN or serial). You get a **`Radio`** instance that works the same regardless of backend:

```python
import asyncio
from icom_lan import create_radio, LanBackendConfig

async def main():
    config = LanBackendConfig(
        host="192.168.1.100",
        username="user",
        password="pass",
    )
    async with create_radio(config) as radio:
        # Read current state
        freq = await radio.get_frequency()
        mode, _ = await radio.get_mode()
        s = await radio.get_s_meter()
        print(f"{freq/1e6:.3f} MHz  {mode}  S={s}")

        # Tune to 20m FT8
        await radio.set_frequency(14_074_000)
        await radio.set_mode("USB")

        # VFO & Split
        await radio.select_vfo("MAIN")
        await radio.set_split_mode(True)

        # CW
        await radio.send_cw_text("CQ CQ DE KN4KYD K")

        # Scope / Waterfall (if radio supports it)
        def on_frame(frame):
            print(f"{frame.start_freq_hz/1e6:.3f}–{frame.end_freq_hz/1e6:.3f} MHz, {len(frame.pixels)} px")
        radio.on_scope_data(on_frame)
        await radio.enable_scope()

asyncio.run(main())
```

**Legacy:** For direct LAN-only code you can still use `IcomRadio(host, username=..., password=...)` — see [Public API Surface](https://morozsm.github.io/icom-lan/api/public-api-surface/) and [API Reference](https://morozsm.github.io/icom-lan/api/radio/).

# Example output
![Scope + waterfall example](docs/assets/scope-example.png)

# Remote power on/off
icom-lan power-on
icom-lan power-off

# UDP relay proxy (for VPN/Tailscale remote access)
icom-lan proxy --radio 192.168.55.40 --port 50001

# Discover radios on LAN + USB serial (unified, deduped)
icom-lan discover

# Built-in Web UI (spectrum, waterfall, controls, audio)
icom-lan web                            # Start on 0.0.0.0:8080
icom-lan web --port 9090                # Custom port
# Then open http://your-ip:8080 in a browser

# Hamlib NET rigctld-compatible server (use with WSJT-X, JS8Call, fldigi)
icom-lan serve                          # Listen on 0.0.0.0:4532
icom-lan serve --port 4532 --read-only  # Read-only mode (no TX control)
icom-lan serve --max-clients 5          # Limit concurrent clients
icom-lan serve --wsjtx-compat           # Pre-warm DATA mode for WSJT-X CAT/PTT flow

# Then in WSJT-X: Rig → Hamlib NET rigctl, Address: localhost, Port: 4532

# All-in-one: Web UI + audio bridge + rigctld
icom-lan web --bridge "BlackHole 2ch"
# Now WSJT-X gets: CAT via rigctld (:4532) + audio via BlackHole

# List available audio devices
icom-lan audio bridge --list-devices

# Audio bridge only (no web UI)
icom-lan audio bridge --device "BlackHole 2ch"
icom-lan audio bridge --device "BlackHole 2ch" --rx-only
```

## API Reference

The main entry point is **`create_radio(config)`** returning a **`Radio`** (see [Public API Surface](https://morozsm.github.io/icom-lan/api/public-api-surface/)). For LAN-only usage, **`IcomRadio`** remains available as a legacy class with the same methods.

### Configuration

| Parameter | Default | Env Var | Description |
|-----------|---------|---------|-------------|
| `host` | — | `ICOM_HOST` | Radio IP address |
| `port` | `50001` | `ICOM_PORT` | Control port |
| `username` | `""` | `ICOM_USER` | Auth username |

| `radio_addr` | `0x98` | — | CI-V address |
| `timeout` | `5.0` | — | Timeout (seconds) |

## How It Works

The library implements the Icom proprietary LAN protocol:

1. **Control port** (50001) — UDP handshake, authentication, session management
2. **CI-V port** (50002) — CI-V command exchange
3. **Audio port** (50003) — RX/TX audio streaming (including full-duplex orchestration)

```
Discovery → Login → Token → Conninfo → CI-V Open → Commands
```

See the [protocol documentation](https://morozsm.github.io/icom-lan/internals/protocol/) for a deep dive.

## Multi-Radio Architecture

icom-lan uses an abstract **Radio Protocol** that enables support for multiple radio backends with a single Web UI and API.

```
┌──────────────────────────────────────────────┐
│          Web UI  /  rigctld  /  CLI           │
├──────────────────────────────────────────────┤
│          Radio Protocol (core)                │

└────────┴──────────┴──────────┴───────────────┘
```

- **`Radio`** — core protocol: freq, mode, PTT, meters, power, levels
- **`AudioCapable`** — audio streaming (LAN or USB audio device)
- **`ScopeCapable`** — spectrum/panadapter data
- **`DualReceiverCapable`** — dual independent receivers (IC-7610 Main/Sub)

📖 **Full protocol docs:** [Radio Protocol](docs/radio-protocol.md)

## Development

### Quick Start (Development Server)

```bash
./run-dev.sh
```

Starts the web server with:
- `ICOM_DEBUG=1` — DEBUG level logging to console + file
- Logs: `logs/icom-lan.log`
- Radio: `192.168.55.40` (override with `ICOM_HOST=...`)
- Web UI: `http://0.0.0.0:8080`

### Debug Logging

```bash
# Enable debug logging (logs to logs/icom-lan.log)
ICOM_DEBUG=1 uv run icom-lan web --host 0.0.0.0 --port 8080

# Custom log file
ICOM_DEBUG=1 ICOM_LOG_FILE=/tmp/debug.log uv run icom-lan web

# Console only (no file)
ICOM_DEBUG=1 ICOM_LOG_FILE= uv run icom-lan web
```

**Server crashed?** Check `logs/icom-lan.log` for traceback.

### Environment Variables

| Variable | Default | Description |
|----------|---------|-------------|
| `ICOM_DEBUG` | `0` | Set to `1` for DEBUG logging + file output |
| `ICOM_LOG_FILE` | `logs/icom-lan.log` | Log file path (auto-created in DEBUG mode) |
| `ICOM_HOST` | `192.168.55.40` | Radio IP address |
| `ICOM_USER` | `moroz` | Radio username |
| `ICOM_PASS` | — | Radio password |

## Testing

```bash
# Unit tests (no radio required) — 3173 tests, 95% coverage
pytest tests/test_*.py

# Mock integration tests (full UDP protocol, no radio required)
pytest tests/test_mock_integration.py

# Integration tests (real radio required)
export ICOM_HOST=192.168.55.40
export ICOM_USER=your_username
export ICOM_PASS=your_password
pytest -m integration tests/integration

# Guarded power-cycle test (will actually power off/on radio)
export ICOM_ALLOW_POWER_CONTROL=1
pytest -m integration tests/integration/test_radio_integration.py::TestPowerHardware::test_power_cycle_roundtrip -q -s

# Soak test (seconds)
export ICOM_SOAK_SECONDS=120
pytest -m integration tests/integration/test_radio_integration.py::TestSoak::test_soak_retries_and_logging -q -s
```

### Test Suite Quality

## Project Scope

`icom-lan` remains the public MIT-licensed open core for radio control, transport, protocol support, and local-first tooling.

Some future product planning, commercial exploration, or private implementation work may happen outside this repository in separate private repositories. That separation is intentional and does not change the open-source status of `icom-lan` itself.

Public improvements that strengthen the core project may still be contributed here when appropriate.
