When I operate my K2 between 7180 and 7190 Khz the VCO seems to worble or
becomes unstable. Any other band or frequency is fine. I have removed RFC15
and replaced it with a direct wire connection then later a ferrite bead.
C91's value was increased from .001 uf to .01 uf. c*88 is still 68pf but
with the advice of Elecraft Technical support I reduced the lead length of
this component to as short as possable. These changes seem to help reduce
the bandwidth of instablity but not totally eliminate it.
The rig works fine on all bands and puts out 10+ watts.
Any suggestions
