You got that right! :-)

After an hour of messing with this, I now have some very clean hands, some
very clean paddles, and the things still only work reliably when
my fingers are wet. Increasing the sensitivity only sets off a string
of dots.and or dashes.... maddening!

I think I'll wire a set of paddles to it and call it a day. Works fine
otherwise, and thanks for the hints on the bottom adjustments.

Thanks very much one and all!

John
