Dragon Labs CR-8: An 8-Channel Coherent SDR Crowdfunding Soon
17 hours ago
- Dragon Labs CR-8 is an 8-channel coherent SDR with 12-bit ADC, tuning 25–1750 MHz, and 8 MHz bandwidth per channel.
- Coherent design supports radio direction finding, beamforming, and antenna diversity.
- Originally created for a Master's thesis by SDR++ author Alexandre Rouma.
- Uses R860 tuners and MCP3721-200 ADC with built-in fractional delay recovery for phase alignment.
- Native support in SDR++ and SatDump; GNU Radio source block available; C API open source, firmware closed.
- Target price $500–600 for bare PCB with optional CNC-milled enclosure; crowdfunding on CrowdSupply soon.
- User comment: seeks RF splitters and discusses homebrew DF software using FFT autodetection and UNIX pipeline.
- User asks about real-time raw sample dumping via USB 3.0 to SSD without loss and retuning without manual antenna changes.
