K3 Loss of VFO B control

Tom Boucher

I have had 2 failed encoders and am waiting for the second replacement. In my case, it was not due to any shorts occurring although I believe Elecraft are now advising the fitting of an adhesive rubber insulating pad behind VFO B encoder. Looks like they had a bad batch from the manufacturer, Bourns.

I had a bad encoder assembly in the K3 I assembled recently - I
proved it by swapping A and B encoders and observing the problem
switch with it. Elecraft shipped me a new one which fixed it (after
much sweat replacing it - that front panel removal is a PITA).

I suspect Elecraft is not checking the encoders before shipping them to us.

Re: K3 Loss of VFO B control

I think it would be a good idea if Elecraft would start checking
every encoder before shipping. It is VERY difficult to
disassemble/reassemble that front panel.

How about it, elecraft - can you start checking them there?

Also - do we need to be concerned that other components of the K3 are
not being checked 100% before they are sent to us?
