[Elecraft] KAT 2 C55 null Query

[Alva Anderson W5VCJ]

Vic,

  I had the same problem, and the readings were unstable anyway. If I tried
to get closer, they seemed to vary wildly. Try turning down the power to 1W
to do the null adj. Then things will get much easier. BTW, others have said
that 009-011 or so worked just fine for them.
