Hi all, More info...
Was unaware of the power recommendations on 50MHz... I was running 100W calling CQ on 50MHz when the problem suddenly arose. Maybe running 100W on 6M has been the cause? If I dial up 100W on any band, RF power as indicated on the K3 display is 70W. I am unable to get more than 70W on any band... And running very latest software 4.22.
