The Hermes-Lite SDR: an open source HF transceiver based on a broadband modem chip

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.

N6QW introduces the Sudden QRP SSB Transceiver

Many thanks to SWLing Post contributor, Pete Eaton (WB9FLW), who writes:

From the fertile mind of QRP Hall Of Fame Pete N6QW comes a new Radio Project, the Sudden QRP SSB Transceiver. If you have never Scratch Built such a Rig and would like to N6QW’s latest offering deserves close inspection.

Using only readily available (and cheap) components (and few of them) one can build a Full Blown SSB Transceiver for either 40 or 20 meters. The Radio’s Design will be featured in 2 installments of GQRP’s Sprat Magazine. The 1st being in the Fall issue (Receiver/LO) and the second part with come in the Spring 2019 issue (Transmitter).

Pete is also providing extensive documentation on his Website:

One use for the Rig is on the Digital Modes, to that end he has design a simple Digital Adapter (which is also described on n6qw.com). One possibility is for a dedicated FT8 Transceiver!

Even if you do not intend to build the Rig take a moment to check out his Web Page. There you will find a wealth of information on designing and building such Transceivers.

Thanks for the tip, Pete! How exciting! This looks like an innovative little rig and I love the concept of only using accessible components–in the end, that will give this little rig some longevity.
