 Equipment: KX3 S/N 7210, FW 02.25

Problem:
6M band -> VSWR 1.8:1 (KX3 meter) on 50ohm load connected directly to ant
 connector (no cable).

Followed by this UPDATE:
The test was to disconnect the remove the ATU board and connect the RF board directly to
the antenna port - which worked OK - 1.2:1.  With ATU installed and
auto-tuned, I get 10 watts delivered to the load, so in my case the bypass
VSWR is little high, but not really a concern.  Since the ATU *is*
installed, just tune it and everything works fine.


I'm not sure I understand......are you saying with the ATU removed the VSWR is 1.2:1 and with it

installed but not tuned it's 1.8:1 until the ATU "kicks in and does its job???
