[Elecraft] [K3] losing FP buttons, one or two at a time

[Steve Ward]

For the benefit of the list, at the suggestion of several folks here I 
removed the FP and cleaned the contacts with Deoxit.  Re-assembled and 
all keys/buttons now work perfectly.

It appears to me that it might have been a good investment to use 
gold-plated header pins and sockets for the front panel instead of 
tin-plated...
