This VFO was designed as an add-on to the SCD TX/RX that George designed many years ago. It was realised that it would work with the Club Sudden TX/RX kits to give them digital tuning.
This is NOT a kit - it is a PCB only, you make up your own kit, but the instructions for this are downloadable below and include suggested sources for non-club sales items. These instructions include how to program the Teensy microprocessor on the board, and also, how to connect the finished and programmed board to the Sudden TX & RX kits. Shown here are pictures of the finished PCB, and the PCB before the build.
