[Elecraft] KAT2 R6 question

[Joe P]

Hi Robert,

I can answer this one since I went through the exact same confusion a 
few days ago :-)  Don't install R6 now. There are several tests and 
adjustments to be made before R6 can safely be installed.  It's not 
installed until step 5 on page 17 of the manual (after the bridge null 
adjustment).

The short story is that if the SWR bridge circuit in the KAT2 isn't 
working properly and R6 is installed, your K2 may try putting out more 
power than its PA can handle.  Keeping R6 out until after verifying the 
SWR detector is working properly prevents this.
