[Elecraft] K2 glitch finally found!

Gary Surrency must be the most patient person on the earth.  He just  
emailed me twice within 1/2 hour of my questions.

I can now report that I HAVE LCD READOUT!

I had to replace all electrolytics on the Control Board to find my  
error.  I found that I soldered C45 (on the bottom of the board)  
across pads of U6 instead of U8.  I missed it on several rechecks  
because it was new and not listed on parts placement diagrams in the  
back of the manual.

I want to thank everyone who has helped me so far...Don Wilhelm comes  
to mind.

Also, thanks to N0SS for pix of circuit boards.

Now, I have a question (of course).
My first resolder job was C13 on Control Board was, naturally, the  
worst.  On replacing the cap, I note that the pad is damaged on the  
negative lead.  I soldered over to an undamaged part (I hope  
successfully).

My question: is the negative lead supposed to be directly to ground?  
(perhaps soldered on the top of the board)  I get about a meg of  
resistance between the lead and ground.
Is this a problem?

Now to build the RF probe.

By the way, I am now a ham again ... after a hiatus of over 30  
years.  I just passed levels 1 thru 4 in one sitting over the weekend.
I didn't expect to pass the Extra but I studied like hell.  The ARRL  
books are fantastic.  Couldn't have done it w/o them.

So, I'll be able to use a new call sign within a few weeks!

John
