40 meter transmitter and DC receiver on one board. Sidetone, VXO. Latest version (v.2) has same circuit, but with an improved T/R switch, antenna jack and real brass key.
Welcome to our new website. As we kick off our 7th year we are introducing a new more modern look to the classic breadboard. We are also introducing serveral new kits and services. Due to many requests, we can now build any kit for you...but we still believe that you get more enjoyment from the building experience. All of our kits are complete, with all parts, high quality american made circuit boards, instructions, free technical support and personal service. Now in my 51st year as a ham, I still enjoy the thrill of making a contact with simple low power equipment, and I hope you will too.
