My Elecraft K1 is a need little rig. One thing I think it missed was a zero beat indicator. K6XX designed just that. Christmas holiday is the perfect period for a little home brewing, so I warmed up the solder iron.
After a hour or so the kit was finished. My first attempt with SMD’s. I’m not disappointed with the result. The test drive isn’t successful yet. All though I’ve seen the led blinking, I can’t get it to work. The SMD variable resistor feels weird (no resistance when adjusting) so I think maybe I damaged it. In the manual there is a piece with voltage points. I hope I can find some time to check all points and figure out what is going wrong.
