[Elecraft] KAT2 - Bridge Null Adjustment problem

[Sanger, Joseph]

R6 is currently uninstalled ... I am still trying to do the CALn null
adjustment ... as I said, instead of having HI showing up continuously,
I know have only '000' on the display.  (I don't know if this is
significant, but the manual says the display should look something like
'075 ATU' but I only see '000', not '000 ATU' ... 

In any event, I have checked T1 3 times already, reheated the leads,
made sure the green jumper cable across it is in place ... again checked
continuity of the RF cable .... and of course checked for the 3rd time
that the ground and hot leads weren't reversed ...

Gonna pull it apart again and look at the soldering on the relays AGAIN
... this situation changed when I soldered a row of pins on one of the
relays that I had missed .... I think I was better off when they ere
unsoldered!  At least I had SOME output!

:-)

Have you installed R6 yet?  Page 17 -  5th step is to install a 47 ohm
1/4 
watt resistor in the KAT2.  This is the info to the K2 microprocessor to
set 
the power level out of the K2.
