[Elecraft] K3 Hi SWR when sending CW

[Don Wilhelm]

Barry,

I don't know the answer in your particular case, but ....

Normally having a difference in SWR for tuning (low power) and operation 
(higher power) is an indication that you have some faulty connection in 
your antenna system - look for loose connectors, places where you might 
have arc-over and things of that nature.
