Thanks to all that responded.
Turns out that somewhere along the testing stages I ended up with a bad
connection on a PL-259. Everything looked good on the dummy load, but after
connecting, disconnecting, reversing etc. the problem became apparent.
I also removed panels and did a better job sanding the connections for
ground and do not seem to have the 40 meter problem anymore unless that went
away with the feedline fix.
So all is good :)
73,
Rich

Morning Dan,
Agree with all. My thinking was to remove the antenna system from the
equation so that the "baseline" could be checked out before dealing with
any
antenna system induced problems. I know nothing about the Daiwa, but if it
is supplied with mains power any ground loop Power Supply - K2/100 -
KAT100 - Daiwa - mains , or variations of this, might become "visible". I
think Rich has the Daiwa between KAT100 and antenna - but that's for Rich
to
say !!
Will standby with interest.

Is the Diawa between the K2 and the Tuner, or between the Tuner and the
Antenna?
Is the Antenna resonant?
You should not expect a "flat" SWR after the tuner unless the
antenna/feedline system is a perfect match - That's the purpose of the
tuner
in the first place.
To compare apples to apples, check the SWR of the same thing at the same
spot. IE, put the Diawa in the line only, measure SWR, remove the Diawa
and
put the KAT100 in line using the same connectors and cables, turn off the
Auto-tuning function (I forget - CALP?), and check again - Same
frequency,
Same antenna, Same feeders, Same cables, jumpers, connectors and testing
location.
Let us know what you find.

it may be as high as 4:1 on some bands even when the tuner says it is
flat
or near flat.
