[Hallicrafters] SX-42, Band 4

[Carole White-Connor]

Thank for all the help and encouragement!

Here's where I'm at. The SX-42 works well on Bands 1 and 2 and very well on Band 3.
However, it is extremely weak on Band 4 (15-30 mHz). By extremely weak, I mean that
in the early evening I can get only  3 or 4 stations weakly on that band. I have
replaced all the paper caps and out-of-spec resistors in, on, under, behind and
near the bandswitch. Since Band 3 works, that shows that the 1st RF stage is
working properly.

I have noticed a wire attached to the side of the fourth bandswitch wafer from the
front. It's about 1 inch long and I can't figure where that should go. I have tried
it on all bandswitch lugs within a 1-inch radius but it has not improved Band 4
performance.

Any ideas? How should I troubleshoot this in a logical manner? I find the entire
bandswitching system extremely confusing and difficult to troubleshoot.
