[Elecraft] KAT100 project - removing the control board

[Stan AE7UT]

Well it's up and working FB!

It didn't go as smoothly as I thought however.
I kept getting an intermittent problem.  When I got it all put 
together and aligned the tuner wouldn't power on.  I'd pull the
plug and connect it together and it would fire up then I'd move
it and it wouldn't come on.
Then was just dead....  I was sure it had to be the cable or the
DB9 connector.
I sucked all the solder off the DB9 and soldered it (twice)
I then pulled the cable apart and soldered it again.
I swear I put that dang thing together 10 times or more.  
I just knew the connector had to be the problem.  Then I started
looking at all my solder joints and looked at the traces from the DB9
connector.  One led to the an IC chip.  That single pin was unsoldered.
I soldered it and it's been rock solid.  It only took 6 hours to find the 
problem!  Now it's 2 AM but the thing works.

Thanks again for all the help.
