Wow! Don, you're good! I had looked at those pins under 5x magnification
and they looked fine. I reflowed those pins and a couple of more on the
board that did look questionable and now she works fine!
73 and Thanks a Million!

James,
I have to take you at your word that the AGC is working OK. If that is in
fact true and you cannot get good S-meter indications on the bargraph, the
only thing that could be wrong is th esoldering of pins 9 and 10 of RP6 or
the soldering of U6 pin 3 (all on the Control Board). Check those first.
Should that not be the problem, then more extensive checks of the AGC
circuit are in order, and you can also conclude that your AGC is *not*
working properly.
Remember that the most common cause of kit problems is soldering problems.
When in doubt, check the soldering, then recheck the soldering. When you
have finished that, check the soldering.
73,
Don W3FPR

With the RF gain fully ccw the S meter will not light at all. I have
tried it with the meter set in both DOT and BAR. Now get this, at the
end of PART II Alignment, CAL S HI did work. Something messed it up
during final construction. FWIW the Bar Display DOES work in transmit
showing RF/ALC so its not burned out and the first segment comes on in
CAL S LO. Any suggestions as to where to look next? Does anybody know
if Elecraft is working on Dec 31?
