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

[Mark Raybould]

I have built, installed and tested a keying circuit and followed the
instructions to interface the KXPA100 with the "Basic Operation with any
Transceiver".  My KX3 requires PA Mode to be On allowing all antenna
matching to be done by the KXPA100.  With the K2 and its KAT2 ATU, I cannot
identify how to bypass the ATU and allow the KXPA100's ATU to do the
antenna matching.  I have previously adjusted the KXPA100's ALC to
accommodate an FT817.

Or, use J4 Ant on the RF Board as the interface to the KXPA100.  The relays
in the K2 will click and have no effect on the matching to the KXPA100.  In
this configuration, a 1.5 Watt unattenuated by the 3db KXPA100 Switch,
shows a power output of 60 Watts on all KXPA100 modes.

Any comments and/or observations are most welcome.
