Backend changes (routes/aprs.py): - Remove -q h flag from direwolf to enable audio level output - Add parse_audio_level() to extract levels from direwolf output - Add rate-limiting (max 10 updates/sec, min 2-level change) - Push meter events to SSE queue as type='meter' Frontend changes: - Add signal meter widget to APRS sidebar - Horizontal bar gauge with gradient (green->cyan->yellow->red) - Numeric level display (0-100) - "BURST" indicator for levels >70 - Status text (weak/moderate/strong signal) - "No RF activity" state after 5 seconds of silence - CSS styles in static/css/modes/aprs.css Also added UK region to dropdown (same freq as Europe: 144.800) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

Support the developer of this open-source project
Signal Intelligence Platform
A web-based interface for software-defined radio tools.
Features
- Pager Decoding - POCSAG/FLEX via rtl_fm + multimon-ng
- 433MHz Sensors - Weather stations, TPMS, IoT devices via rtl_433
- Aircraft Tracking - ADS-B via dump1090 with real-time map and radar
- ACARS Messaging - Aircraft datalink messages via acarsdec
- Listening Post - Frequency scanner with audio monitoring
- Satellite Tracking - Pass prediction using TLE data
- WiFi Scanning - Monitor mode reconnaissance via aircrack-ng
- Bluetooth Scanning - Device discovery and tracker detection
Installation / Debian / Ubuntu / MacOS
**1. Clone and run:**
```bash
git clone https://github.com/smittix/intercept.git
cd intercept
./setup.sh
sudo -E venv/bin/python intercept.py
Docker (Alternative)
git clone https://github.com/smittix/intercept.git
cd intercept
docker compose up -d
Note: Docker requires privileged mode for USB SDR access. See
docker-compose.ymlfor configuration options.
Open the Interface
After starting, open http://localhost:5050 in your browser.
Hardware Requirements
| Hardware | Purpose | Price |
|---|---|---|
| RTL-SDR | Required for all SDR features | ~$25-35 |
| WiFi adapter | Must support promiscuous (monitor) mode | ~$20-40 |
| Bluetooth adapter | Device scanning (usually built-in) | - |
| GPS | Any Linux supported GPS Unit | ~10 |
Most features work with a basic RTL-SDR dongle (RTL2832U + R820T2).
| ❗ Not using an RTL-SDR Device? |
|---|
| Intercept supports any device that SoapySDR supports. You must however have the correct module for your device installed! For example if you have an SDRPlay device you'd need to install soapysdr-module-sdrplay. |
| ❗ GPS Usage |
|---|
| gpsd is needed for real time location. Intercept automatically checks to see if you're running gpsd in the background when any maps are rendered. |
