KXPA100 Fault on ANT1

[Gerald Eberle]

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. Where should I start to search? Any help is appreciated.

Thanks and 73

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
