[Elecraft] Deaf K2 and solution

[George W Whatley]

After completing the IF alignment (p 64) I could hear nothing on K2
#4785.  After much hairpulling and unfruitful signal tracing, I gave up. 
Then, my VERY good friend, Roy, W4WFB, offered to have a look.  He has
built two K2s.  He found the problem, and here's what it was.  On p. 59
(in my manual), it calls for D40 and D41 to be installed on the underside
of the RF board.  I put them in the wrong holes.  Roy moved them and
bingo, #4758 came to life FB.  The location of these diodes is not marked
on the board, so I suggest you study  fig 6-23 very carefully before
soldering.  I have been building stuff, kits and from scratch, including
my own amplifier designs, for 45 years and I still managed to mess it up.
 Thanks, Roy!!!
