It’s an SDR transceiver for HF which does all the work of quadrature splitting and mixing with homebrewed modules rather than the more usual technique of hiding it in an SDR chip.

Making a multi-band amateur radio transceiver has always been a somewhat challenging project, and making one that also supported different modes would for many years have been of almost impossible … ...

Basics of SDR. An SDR is a highly flexible transceiver platform consisting primarily of a radio front end (RFE), mixed-signal interfaces, and processing support in the digital backend (Fig. 1).

I wanted a different solution and thought of using ultrasonic transducers configured in a software-defined radio (SDR) type framework as the transceiver. While working on the design I realized that it ...
