[Elecraft] KAT2 Problem

[Thomas Beaudry]

Yep, it's smaller than the others.  I just looked to double check also. 
  What kind of voltages should I be getting at R1?

>> 0.775 V  fully clockwise
>> 0.850 V fully counterclockwise

>>> If it is, there is a problem on the input to the processor and U4.

>>> connected to the beginning of winding three?
>>
>> Yep, windings are hooked up as they should be.
