K3 TX Gain failure

[Mike Reublin NF4L]

I just loaded 5.14 firmware, and ran the 50W TX gain calibration. It fails, the K3 displays ERR TXG. The book says band-pass or low-pass filters out of whack.

What's my remedy?

73, Mike NF4L

The 5W TX cal fails also, but no error message on the K3.

I also saw 5W TX Cal fail several times, even crashed k3util "somehow
some text lines were modified ...", until I recabled so that MFJ dummy
load was on ANT1, i.e. it failed going through my normal hookup
ANT1->KPA500->KAT500->ant_switch->dummy, and it also failed with
ANT2->dummy, but it did succeed with ANT1->dummy.

I then installed 50 Ohm load on XVTR OUT, and attempted 1mW TX Cal,
but it failed:
IsSamplingComplete: Unexpected response 'DB 2.08 MW;' to ".
1 milliwatt calibration failed.
