Curious problem after installing KPA3 and KAT3

[Doug Person]

Hi Folks,

Installing the KPA3 and KAT3 is pretty straight forward.  That's why I
don't understand what's wrong.  Looks like ANT1 and ANT2 are both open.  
I can see the leads physically connected in the right order to the
KAT3.  The KAT3 is enabled in the menu, as is the KPA3.  But when I
tried to run the calibration program, it says the SWR is too high.  When
I attempt to transmit with just 5 watts, the internal SWR meter
indicates very high SWR.

I admit that I am recovering from major surgery (with the usual
assortment of drugs) and my brain may not be fully functional yet, but I
can't see what I may have done wrong...

Any thoughts?

Thanks,

Doug -- K0DXV

Make sure that the connector on the bottom of the KAT3 is lined up properly. I succeeded
in getting it wrong once (although I noticed it before trying it out, so I don't know if
this is the symptom you'd see).

Yes, of course.  And verified the dummy load was working correctly with
an MFJ 259.

I removed the KAT3 and reinstalled the KANT3.  SWR now normal.
