[Elecraft] K3 - TX Gain calibration fail

Just ran this and it fails at 29MHz with high swr, somewhere between 2 and
4:1. Coax dummy load directly into Ant1 and gives high swr on both 5w and
50w using the K3 Utility as well as manually. All other bands fine
(including 24MHz) and transmits fine on 28MHz when antenna matched using the
KAT3.

Tried other dummy loads too - curious why it should be showing high swr only
on 10m......

(Tried that weird advice of 'tuning' the KAT3 into the dummy load to 'teach
it the LC settings for Bypass' too but no difference)
