[Elecraft] AGC Alignment

[vze3v8dt at verizon.net]

When recently building mine I had a similar problem.  I moved my ground 
connection to one of the small loops on the board and that was enough to 
give me a higher reading and tweak R1 into range.  Seems that the 
"Ground" that I had picked wasn't as good of a ground as I thought! 

There certainly may be another reason for your problem as well, but just 
thought I would offer my experience.  Hope it helps!
