## RTL-SDR Setup (Linux)

### Add udev rules

If your RTL-SDR isn't detected, create udev rules:

```bash
sudo bash -c 'cat > /etc/udev/rules.d/20-rtlsdr.rules << EOF
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", MODE="0666"
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2832", MODE="0666"
EOF'

sudo udevadm control --reload-rules
sudo udevadm trigger
```

Then unplug and replug your RTL-SDR.

### Blacklist DVB-T driver

The default DVB-T driver conflicts with rtl-sdr:

```bash
echo "blacklist dvb_usb_rtl28xxu" | sudo tee /etc/modprobe.d/blacklist-rtl.conf
sudo modprobe -r dvb_usb_rtl28xxu
```

---

## Verify Installation

### Check dependencies
```bash
python3 intercept.py --check-deps
```

### Test SDR detection
```bash
# RTL-SDR
rtl_test

# LimeSDR/HackRF (via SoapySDR)
SoapySDRUtil --find
```

---

## Python Environment

### Using setup.sh (Recommended)
```bash
./setup.sh
```

This automatically:
- Detects your OS
- Creates a virtual environment if needed (for PEP 668 systems)
- Installs Python dependencies
- Checks for required tools

### Manual setup
```bash
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
```

---

## Running INTERCEPT

After installation:

```bash
sudo -E venv/bin/python intercept.py

# Custom port
INTERCEPT_PORT=8080 sudo -E venv/bin/python intercept.py
```

Open **http://localhost:5050** in your browser.

## dump1090 Notes

### Package names vary by distribution:
- `dump1090-mutability` - Most common
- `dump1090-fa` - FlightAware version (recommended)
- `dump1090` - Generic

### Not in repositories (Debian Trixie)?

Install FlightAware's version:
https://flightaware.com/adsb/piaware/install

Or build from source:
https://github.com/flightaware/dump1090

---

## TSCM Mode Requirements

TSCM (Technical Surveillance Countermeasures) mode requires specific hardware for full functionality:

### BLE Scanning (Tracker Detection)
- Any Bluetooth adapter supported by your OS
- `bleak` Python library for manufacturer data detection
- Detects: AirTags, Tile, SmartTags, ESP32/ESP8266 devices

```bash
# Install bleak
pip install bleak>=0.21.0

# Or via apt (Debian/Ubuntu)
sudo apt install python3-bleak
```

### RF Spectrum Analysis
- **RTL-SDR dongle** (required for RF sweeps)
- `rtl_power` command from `rtl-sdr` package

Frequency bands scanned:
| Band | Frequency | Purpose |
|------|-----------|---------|
| FM Broadcast | 88-108 MHz | FM bugs |
| 315 MHz ISM | 315 MHz | US wireless devices |
| 433 MHz ISM | 433-434 MHz | EU wireless devices |
| 868 MHz ISM | 868-869 MHz | EU IoT devices |
| 915 MHz ISM | 902-928 MHz | US IoT devices |
| 1.2 GHz | 1200-1300 MHz | Video transmitters |
| 2.4 GHz ISM | 2400-2500 MHz | WiFi/BT/Video |

```bash
# Linux
sudo apt install rtl-sdr

# macOS
brew install librtlsdr
```

### WiFi Scanning
- Standard WiFi adapter (managed mode for basic scanning)
- Monitor mode capable adapter for advanced features
- `aircrack-ng` suite for monitor mode management

## Notes

- **Bluetooth on macOS**: Uses bleak library (CoreBluetooth backend), bluez tools not needed
- **WiFi on macOS**: Monitor mode has limited support, full functionality on Linux
- **System tools**: `iw`, `iwconfig`, `rfkill`, `ip` are pre-installed on most Linux systems
- **TSCM on macOS**: BLE and WiFi scanning work; RF spectrum requires RTL-SDR
