[Elecraft] Need KAT2 Help

[Don Wilhelm]

Tom,

Yes, the balance point is very 'touchy' - such is the situation anytime 
you are trying to get a null (on any kind of equipment - the null range 
is very small, and ideally is a single point).  On the KAT2, the normal 
lowest reading on the display is in the 009 to 011 range as you have 
found - from that I would say all is well.

Yes, the Elecraft K2 option manuals do not have as much detailed 
supplemental information as the K2 manual because the builder would 
normally have already experienced the details in the K2 manual.  That 
was true initially, but now many K2 are being purchased used and the new 
owner adds options without having that initial K2 building experience.
As far as removing stuff that was not there, the manual must be written 
to cover any possible K2 configuration - thus, it is important  to 
observe all  the  "If"  statements - if you do not have a particular 
option installed, you will have nothing to remove.

73,
