K2 encoder shaft and new knob

Martin Sole-3
I'm in the finishing straight for the build of my nice shiny new K2,
it's been great fun and I'm looking forward to using it soon.

The new vfo encoder shaft does seem to be a bit too long, either that or
the hole drilled in the knob is not sufficiently deep enough. I suppose
the simplest solution is to add extra padding between the knob and
panel. I'm just a bit concerned it will look a little odd with 5mm of
wadding in there.

Is there a consensus on a best method to resolve this little dilemma?

Thanks

Martin, HS0ZED

Martin,

How many felt washers did you receive with your K2 kit? - it should have
been 3.
If you had only one, contact Elecraft support to get the other two.

With the new encoder, you must flush cut (yes right down into the
solder) not only the leads on the encoder board, but also the Control
Board in the area where the encoder board could make contact.
It may also be a good idea to add an insulating material like fish paper
or a piece of plastic between the two boards.

73,

Thanks Don,

I received only the one felt washer. I'll request the remaining 2 :)

At initial test I had the 'not tuning problem' and fixed it with a shim
of stiff paper. That was despite the flushest of cutting both on the
encoder and control boards. That's a tight squeeze in there but all good
now except for the free-wheeling knob which incidentally is a big
improvement on the earlier one I think. A nice classy look n feel.

Thanks
