Many thanks to SWLing Post contributor, Pete Eaton, who writes:
Don’t know if you are familiar with this project, a full blown 5 watt HF SDR Transceiver for less than $300!
No sound cards, DUC/DDC architecture.
Here’s the project description by Steve Haynal via YouTube:
The Hermes-Lite is a low-cost direct down/up conversion software defined amateur radio HF transceiver based on a broadband modem chip and the Hermes SDR project. It is entirely open source and open hardware, including the tools used for design and fabrication files. Over 100 Hermes-Lite 2.0 units have been successfully built.
The FOSSi Foundation is proud to announce Latch-Up, a conference dedicated to free and open source silicon to be held over the weekend of May 4th and 5th in Portland, Oregon, USA. Latch-Up: a weekend of presentations and networking for the open source digital design community, much like its European sister conference ORConf. Produced by NDV.
Fascinating! Thank you for sharing, Pete!
