Aaron,
Your tests leave a couple questions - I could assume, but I would rather
not - unsaid things often reveal problems.
Are you powering the KX3 from an external supply having at least a 13.8
volt output?
After you connected the dummy load, did you do an ATU TUNE?
Is there any chance you could have had a static surge on the antenna
coax that could have zapped the wattmeter diodes?
Email supp...@elecraft.com to see if they can give you some points to
measure.
73,

The ATU on my KX3 is not tuning. When I hit the tune button I hear the
relays and the display shows an SWR of 25.4-1
Here is what I have done so far.
Under the menu, the ATU MD is set to Auto
I hooked the KX3 to a dummy load with a good piece of coax and it still
showed SWR of 25.4-1.
I opened the KX3 up, removed the batteries, removed the 2-meter
transverter, and removed the ATU. The cable from J1 to the BNC was well
connected at both ends. Upon inspection, I could find no loose cables or
parts in the rest of the KX3.
I reassembled everything and I am still getting an SWR of 25.4-1 with the
dummy load.
