Dave nice on your successful build. Scratchy audio heard when exercising the tuner -- wow very cool to translate mechanical motion into audio modulated electrons -- this is called microphonics, I

I have built the 4SQRP Group antenna tuner and really thinkit is a fantastic kit and easy to build with the provided instructions. Itseems to work quite well and I have tested it against other antenna

Good thought -- I did not consider the possibility of no LO reaching the SA612 IC -- in that case a mixer becomes a resistor, and perhaps only an AM receiver. Looking forward to hearing that the
