Circuit boards and kits are available so that you can construct the designs yourself. Nothing is more fun than making contacts with something you built!

All designs featured here use only through hole parts or pre-assembled modules to make construction easy and fun and most do not require any test equipment to adjust.

Designs include SSB SDR transmitter designs that can serve as a complete station or basis for your unique design. Add this transmitter to the All mode 1 kHz to 1.7 GHz receiver for a complete HF SSB SDR transceiver. The circuit boards are usable for an analog design SSB transmitter as well with modified software and addition of a LCD display and a couple of encoders.
