[Elecraft] K1 front panel protection.

Fri Jun 21 13:25:01 2002

First off, I would like to say that your knob looks pretty spiffy
('spiffy' means 'great').  Since you are already set up to do the
work, you might consider going into business reworking K1 knobs.  I'll
bet that you would be rich in no time at all.

shaft ~0.1" so that the knob could sit closer to the

its front edges so that it was easier on the tuning

face of the knob is 0.6" from the front panel, about
> .05" more than the AF Gain and RIT knobs.
