I have a recurring problem with this with a homemade switchbox (luckily in my
shack, not
on a tower). Deoxit does help, but the problem recurs.
It's been suggested that I run a bit of DC through the contacts to electrically
'wet'
them. I bet this would work, but it's slightly complicated and I haven't tried
it.
