[Elecraft] KAT 2 C55 null Query

[Vic Winton]

All,

I was installing the KAT2 last night and got to the C55 null adjustment.

I am trying to achieve a "Cal n " reading "as close to 000 as possible" per
the manual.

I can only achieve a reading as low as 010. Is this normal? 

C55 was a bit stiff and seems rather critical in its adjustment. I
momentarily got a reading of 003 but lost it as I tried to go lower and now
010 seems as low as I can get.

I turned th4 cap right round a couple of times to free it up a bit. Should I
do this some more to loosen it slightly - I am worried about damaging it
with excessive turning.

The voltage check on the ic is fine... 0v on receive and 3.5v on tx.

Many thanks,

PS Adding the noise blanker and atu this week has given the rig a much more
solid feel. Baby's gaining weight !
