Hi Dink
Many thanks for your help. It turned out to be the same issue as you
experienced. After removing the ANT1 SO239 connection from the ATU board I’ve
measured also a shorted cable. To be sure that there are no other issues, I
connected the ANT2 SO239 to ANT1 on the ATU board and
fyi Gerald
I just had a similar issue.
The coax connection between the ANT1 SO239 and the board shorted at the
crimped TMP connector
(after two years of use). Elecraft support (Rob) was helpful in
troubleshooting too.
Might check the spark gaps on the board too
cheers

Hi All
While I’ve used my KX3 / KXPA100 with ATU in the Rtty contest a fault was
displayed and ANT1 did not work anymore. No receive and high swr. PA and ATU on
ANT2 are working as expected and the relays is switching between the 2
antennas. I think I’ve fried something on the input of ANT1.
