Hi Tom.
Yes, I think that brushing up the R7 to get the corrosion out of the joints
could make quite a difference. It's probably a first step in trying to get
that antenna going. As for the antenna tuner in the TS850S, if it is
anything like the auto tuner in the TS450S and TS690S, it is probably a
pretty tolerant antenna tuner. I personally think that the AT450 that is
used in the two radios that I just mentioned is a real gem, and it
sometimes even outperforms the MFJ993 tuner that I have. Keep in mind that
when trying to debug the G5RV, the ladder line cares a lot more about what
is around it than coax fed antenna systems do, so try to look and see if
there are any metal objects near it that could be affecting it. G5RVs work
best when they are up in the free and clear, but few of us have that luxury.
