[Elecraft] K3 Power Amp Shut Down Problem

[Don Wilhelm]

Don,

I don't have any evidence to indicate that you have another problem 
lurking around.
I would have to defer to Wayne for speculation about why you did not see 
the HI SWR message yet experienced the PA shutdown.  I do not know *all* 
the details of the power shutdown mechanism (but high SWR is one 
condition) and why no message was produced - Wayne would have to answer 
that.

Can you reproduce it with the bad cable?  If so, perhaps additional data 
can be derived.
