Wayne,

Thank you for your response.

I do believe that the K3 cut power because the SWR on the antenna port 
went too high. No I never saw any error message at any time. And that is 
my point and basis for the request to have an error message for this 
condition. Scanning the list of error messages on page 64 of the user 
manual dated January 2009, I do not see any error message that states 
that the SWR was detected to be too high.

Please let me know if you do implement such an error message.

Thanks.

Don Nelson, N0YE
