Pete; Always do what the master says. Keith knowns more about the K3 than almost anyone.
That 3db figure stands out for me, though. For a component failure or a misadjustment I would expect something else. This sounds more like the antenna is being split, going to another place along with the main RX input. Is it possible you are feeding the same antenna input to both main and sub RX? It will be interesting to see what you and Keith come up with. 73!
