[Elecraft] K2 with KAT2 and KXPA100 with ATU - Correct setup?

[Don Wilhelm]

Mark,

Set the K2 ATU menu parameter to CALP or CALS depending on whether you 
want to read the Power or SWR between the K2 and the KXPA100.
Those two setting "bypass" the KAT2 (except for any residual reactance).
CALP will not work because that setting retains the last used L/C 
combination.
