[Elecraft] KAT2 Adjustment Questions

[Michael Eberle]

Hi,

I am in the process of installing the KAT2 and need some clarification 
on the bridge null adjustment procedure.  Following the instructions, I 
set the slot of C55 parallel to the K2 rear panel.  After activating 
TUNE I can adjust it down to about 002 or so.  Then if I put it back 
into receive, then activate TUNE again, it goes back up to about 030.  
Is this normal?   Also, on pin 1 of U4, I am seeing about 2.7 to 2.8 
volts.  Is this close enough to the 3 - 4 volts specified in the manual?

Thanks,
