[Elecraft] RESOLVED: KAT Won't Tune, KPA presents HIGH SWR

Many thanks to Mike Flowers, K6MKF, NCDXC ("It's about DX!"), who calmed 
me down to do the step by step troubleshooting for this issue.  And 
thanks to several others who offered even the smallest suggestion.

To describe the circumstances: K3S->KPA->KAT->ANT

When opening the station Monday evening, the KPA was producing no 
output.  I had attempted to work an easy QSO for me, but called for 
several minutes before I noticed the power was at zero. Nothing out of 
the KPA.

As I went through my usual "what happened now", which means "what 
happened last year that looked like this" I tried the K3S TUNE to see if 
I was in a band segment that hadn't been recently updated. But, the K3S 
showed it was outputting 25 WATTS with an SWR of 11-15:1 - unlikely.  
And the KAT was making no attempt to tune. And the KPA still had zero 
output.

Long story, in hours, short after determining the K3S was fine, then the 
K3S->KAT were fine and then the KPA was not, I retested the reconnected 
KPA after resetting the CONFIG using EDIT+ON at power-up and things are 
back to operation.

Thank you Mike, thank you everyone else, and thank you Elecraft for the 
EDIT+ON option.

See you in CQWW!  73, Byron
