NEW PROJECT JUST COMPLETED

HF SSB/CW RECEIVER

I've just completed a new project and have submitted a new article to QST for publication.  It is a  single band HF receiver that has DDS frequency control, a color display and a crystal filter that can be adjusted for bandwidth from the front panel to optimize detection of the type of signal received.  The pc board measures about  4" by 6".  I will add updates here.  Circuit boards and partial kits will be available.

This receiver has been designed to be a stand-alone receiver or the receiver section of a transceiver.

Featured on this web site you will find information about various devices I have designed and update items for my articles that have been published in QST Magazine.

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!

Super Simple FM SDR Transceiver

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.
