[KX1] Key input doesnt like capacitance

I was having trouble using my Junker straight key with my KX1. There
would be an occasional stutter in the signal on contact release, and
seemingly when contact made also. This key, and I dont know if true of
all Junkers, has a coil in series with 'ground', and from ground to
'tip' is a 100 ohm resistor in series with a .1 uf capacitor. The
problem remained when the coil was bypassed, but when the RC shunt was
removed the problem was resolved.

I just thought I would put that out there in case someone has similar problems.
