[Elecraft] KAT100

Hi 

This does not sound right. You should be able to get the voltage down to around a few mV. It seems like the several I have built would go down to 10 to 20 mV.

  Hi all,
  Just finished building my KAT100 and it seems to be working fine!  Just
  one question though.  The book mentions to tune c31 for lowest voltage
  on pin 3 of U5 and also mentions that it should be as close to 0v as
  possible.  I could get it nowhere near this, best at around 1.6V.  I can
  get the target voltages ok on R3 and R4 so it seems this is ok but I
  find the reference odd.

  Any pointers?

  Ian
