## Sub-GHz Analyzer
1. **Connect HackRF** - Plug in your HackRF One device
2. **Set Frequency** - Enter a frequency in the 300-928 MHz ISM range or use a preset
3. **Start Capture** - Click "Start Capture" to begin signal analysis
4. **View Spectrum** - Real-time spectrum visualization of the selected band
5. **Protocol Decoding** - Identified protocols are displayed with decoded data
### Supported Protocols
Common ISM band protocols including garage doors, key fobs, weather stations, and IoT devices in the 300-928 MHz range.
## DMR Digital Voice
1. **Select Hardware** - Choose your SDR type
2. **Set Frequency** - Enter a DMR repeater frequency or use bookmarks
3. **Start Decoding** - Click "Start Decoding" to begin digital voice reception
4. **Listen** - Audio streams via WebSocket to your browser
5. **View Events** - Decoded talkgroup and radio ID information appears in the event log
### Supported Protocols
- **DMR** - Digital Mobile Radio (Tier I/II)
- **P25** - APCO Project 25
- **NXDN** - Kenwood/Icom digital protocol
- **D-STAR** - Icom digital voice
## Listening Post
1. **Select Hardware** - Choose your SDR type
2. **Set Frequency Range** - Define start and end frequencies for scanning
3. **Start Scanning** - Click "Start Scan" for wideband sweep
4. **View Signals** - Discovered signals are listed with frequency and SNR
5. **Tune In** - Click a signal to tune the audio demodulator
6. **Listen** - Real-time audio plays in your browser
### Demodulation Modes
- **FM** - Narrowband and wideband FM
- **SSB** - Upper and lower sideband for amateur radio and shortwave
## Aircraft Mode (ADS-B)
