[Elecraft] KX3 ATU not working

[Aaron]

For some reason, I could not reply to the mail list.

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.
