Gleaning suggestions -: BC-348 flaky band switch fixing.....
BC-348R , OCR-T.O.-2112R2-3BC-112
I know I have a flaky band switch on my BC-348 - [Band 5] 9.5 - 13.5Mc
; If I fiddle the band switch this band comes alive with hiss... and is
still tuned u,p since WWV; @ 10MC | still touches the needle Indicator
a bit on the high side.
I have ordered Carig Deoxit Gold to clean and protect the contacts:
Are the band switch contacts, silver plated?
1. To Clean contacts : Should I try Deoxit D5 somthing stronger, before
using Deoxit Gold : reference: http://store.caig.com/s.nl/it.I/id.5/.f
Deoxit D5, Is it to strong for the contacts? Any thoughts wold
be most helpful:
2. Will follow the instructions on Page 5-4 paragraphs 10, 11 to
determine the offending sage;
Any thoughts on procedures, got-U's, wach-out's, wold be most helpful
on how the "clean" the switch contacts with out breaking things. I
have 4 cans to investigate 1RF 2RF Det Osc I suspect a loose switch
contact, Pincher, as I can rock the band 5 and get "normal" reception,
audio. This wont be easy.
Thanks
Hutch
