[Elecraft] K3 VFO tuning hash

[James Sarte]

I had a similar issue, except my encoder noise was most noticeable around
5MHz.  After testing and discussions with Wayne, it appears to be due to
"hot synthesizers."

I do not notice this problem in the 6m band.

This noise was previously reported under the title "K3 Tuning encoder pulses
and birdie problem"
In my case it is only noticeable at the low end of 28MHz when there is a low
noise level from the antenna or with a dummy load attached.
Wayne suggested using the noise blanker on a low setting like t1-5, also
tightening screws and tmp cables may help.  In my case it seemed to get
better when I installed the KRX3, but maybe cos I tightened up the screws
and cables.
