I had this problem with 2 KX1's that I have built...The cause of the problem is that the countersunk hole in the front panel for the screw that holds Q6 is a little too deep, allowing the tapered back surface of the screw to contact the transistor's tab...I had to countersink the hole in Q6's tab to overcome this...I have a small countersinking bit, but an ordinary twist drill should also work...It doesn't take much to do the job, just a little bit of material removal is all that is necessary...I didn't use a power drill, I spun the countersink in my fingers...Hope this helps...
Jerry, wa2dkg >I having a bit of a problem. I've just recently completed a build of a KX1 and everything has gone together smoothly, as usual. The problem is with the power transistor, Q6. If I tighten the flathead screw, Q6 must be shorting against something, as the display goes blank and the unit no longer work. (if you listen closely you can even hear the crackle of the short beginning) If I back out the screw the KX1 comes back alive!< _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
