[Elecraft] KAT2 CALIBRATION - R 1 & 2

[Don Wilhelm]

Chris,

You did not say, but I assume you must have the KAT2 set for CALP mode.  
The 0.0r indication shows that there is zero reflected power, which is 
correct if you are operating into a good 50 ohm dummy load..

Switch to CALS and you should see an SWR indication of 1.0 to 1.

Simply use the manual instructions to set R2 to the same relative 
position as R1 and the tuner will work fine.  If you wish to actually 
calibrate the SWR indication, you will need dummy loads that have a 
specific resistance (and zero reactance).  I use 25 ohm and 100 ohm 
loads to properly calibrate the wattmeter SWR calibration, but without 
those tools, just set the potentiometers to match.
