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!

Hi all,
I'm assembling the K2 here (SN 4836) and came to the first
check/alignment. No smoke here so far, but when adjusting the setting
for the AGC as described on page 47 I became suspicious about the
alignment procedure. Adjust R1 for 3.80 V on the DMM. I turned R1 and
reached the end and got stuck on 3.78V. The absolute value of 3.78
doesn't worry me but that I ended up at the limit of the R1. I thought
I should check all variables like DC voltage which should be 8V (was
7.98V so OK). Checked the resistors (mainly RP6 / 5.1K) and, RF gain
potentiometer 5K and the R1 (50K). All looked fine. So what's wrong?
