[Elecraft] Info 080 message started with RF Alignment and Test, Part II

[AC8HU]

Well I thought I was going to be coming on to post what I'd found with the
VFO problem...but now, the Info 080 is back.  As far as the VFO, I
discovered that if I removed the two screws that connect the control board
and front panel board (so that they're not drawn snug to each other), the
VFO works.  It almost seems like the back of the optical encoder board is
somehow shorting to the control board?  I don't know...I put a couple pieces
of electrical tape on the back of the encoder board and gently connected the
two together with the screws and the VFO was still working.

At that point, I went back to the Part 1 tests and alignment, and started
working through Part 1 and Part 2 again.  Everything was once again fine up
until the exact same point - when I switched bands to the 80 meter band,
before tuning to 4000.10, the Info 080 message popped up again.  I said
several things I won't say here, then proceded to do the frequency counter
check anyways just to see where I am.  I didn't actually make a note of the
value but the frequency was somewhere around 10800, a range of 8 to 10 MHz
is specified so this would be marginally acceptable (?) I guess.  Just out
of curiousity, I went ahead and checked the voltage on the left end of R30
(as described in the next step) and found it to be almost exactly 0.00 V -
and adjusting the slug inductor made no difference.  Prior to the
reappearance of the Info 080 message (but before the VFO working again), I
had checked this value, and again didn't write down what the exact numbers
were, but I had some sort of reading and was able to make adjustment over a
wide range using the slug inductor.

Finally, I tried restarting the radio (figuring I knew what would happen),
and the Info 080 message appeared immediately at startup, and I noticed that
relay activity is one again nonexistant.

Now I'm rather discouraged.  I didn't check further but I wouldn't be
surprised if I'm once again seeing the same problems with voltages on U1 and
such.  Knowing the little bit I know about computer troubleshooting, it
seems that I can narrow the problem down to something that's resulting from
the switch from 40 meters to 80 meters while doing frequency counter
checks...but I have no clue at all what that problem could be.  My best
guess, since relay activity comes and goes with the Info 080 message, and
these problems start when I change bands during these tests, is still some
sort of problem with U1, as I've been over solder connections several times.
