This project has moved to https://github.com/turnisland/X-888
A simplified SDR, based on the RX-888:
- Proof-of-concept design
- HF-only, no VHF converter
- Larger PCB, 6-layer
- No bottom-side components
- 0603 passive components
- Improved thermal layout
- Improved RF input filter (bypassable)
- External reference clock input, auto-switching
- Attenuated filter-bypass injector port (used for timesync)
Please see schematic and layout documents.
