I can't really say for sure that every one of my soldering connections is
perfect, there may be one or a couple in there that are still flaky (which
is all it would take, obviously).  However as far as I can tell, I don't
have a consistent problem with soldering.  The connections are all shiny,
solder flows from the component lead out to the edges of the pads, not in
little balls (the few times I've had one of these happen I've taken care of
it when it happened).  I don't have an iron that I can specifically select a
temperature on but it's a 50 watt iron that is adjustable - I have it set
probably around 80-85% of full power.  I've found if I go higher I actually
tend to end up with discolored spots on boards at times - but I don't know
the exact temperature.  (I thought I vaguely remembered that a 50 watt iron
usually was 800 degrees?  Maybe not though.)

I've used two different types of solder in the process - the first was the
end of a spool from Radio Shack that was 60/38/2 silver bearing, and the
spool I'm on now is also Radio Shack but 60/40.

I still really lean towards the fact that the problem reappeared at the
exact same point, down to the precise button press (switching to 80 meters
while in CAL FCTr), suggesting that there's a problem with a component.  It
just seems that since the problem didn't appear randomly along the way but
at the same exact moment, it wouldn't just be a solder connection.  A poor
solder connection would be prone to going out at any moment and the odds of
it doing it the exact same time?
