Hi,
Elecraft already have a mod kit for this kind of
behavior since 2005. The part number is : K2VCOSHLDKT
You can also take a look at the documentation provided
at :

Have a nice day.

Worked Vic, K2VCO this morning on 40m CW. His K2/100 was absolutely
clean with no clicks and no noise on his CW sidebands while he was
running barefoot.
When he ran ran QRO to his Alpha 87A, There were still no clicks, however
there was noise on his sidebands extending out +/- about 1 kHz from

Reading the magnetic field and phase noise saga makes me think of earth
loops. If moving to another power socket- as in moving to another room cures
it. How about using mains isolation transformers so only connection
K2-linear really is the coaxial feeder. Or battery power K2.

Earl,
How strong was Vic's carrier

Interesting Earl, the non exhaustive tests I've done indicate that it is
not due to magnetic fields. But if indeed that is the case, there must
be a relatively easy, if perhaps not elegant, way of significantly
improving this.
Has anyone else investigated this?
