If you're going to use the Si5351, take a look at QRP-Labs Si5351A synthesizer kit.

Gordon. Are the details of your work published anywhere? I'm about to try the same trick on my?old Swan-250C (single band) 6 meter rig. I'm debating whether or not to use Jack's basic VFO circuit & software with an added Si5351?board to provide the carrier oscillator and calibration function, or to just do it all with the Si5351. I'm particularly interested if you had any issues with drive levels or square wave filtering between the digital VFO and the tube radio. Thanks! -- John - WA2FZW
