Chris,
That high SWR indication along with the HI CUR warning usually means
that there is no antenna or dummy load electrically connected.
Check the cable from the KXAT3 to the BNC jack to be certain it is
properly seated.
Did you ever connect an old 75 ohm BNC connector to the KX3? Modern 75
ohm BNC connectors have the same size center pin as the 50 ohm
connectors, but older ones may have a larger center pin.
If you used one of those old 75 ohm connectors, you may have enlarged
the center conductor of the KX3 BNC jack and then later using a 50 ohm
connector, there will be a break in the continuity.
You may be able to bend the fingers of the female BNC jack inward, but
if that is not feasible, replace the BNC jack.
73,

Bill,
Thanks for your response. I tried tuning into a 50 ohm dummy load (using known
good cables), and see the same issue.
Neither the BNC nor the internal cables look damaged in any way.
I'll note I never use an internal battery, so I rarely open the unit.
