[Boatanchors] TS-830S Bandswitch

[Mark K3MSB]

Hi All



A few months ago I did a relay replacement and recap job on a friends
Kenwood TS-830S, along with addressing intermittent operation on 40M.    After
returning the radio to him, the radio worked flawlessly for about two weeks.
Afterwards the radio lost 40M capability.



Prior to working on the radio I read up on the well know 40M issue, which
is really corrosion on the band switch rivets.  I’m aware of the “correct”
procedure to fix it, but I’m a bit dearth of doing that just yet.



I cleared up the intermittent issue by cleaning the band switch with DeOxit.
As mentioned it worked fine afterwards (but only for two weeks), so I'm
hoping the corrosion isn't that serious.



Is there anything stronger than DeOxit that you can recommend to get rid of
minor corrosion on this band switch?  As said, I really don’t want to pull
the band switch wafers out if I don’t have to.



Thanks & 73
