[Elecraft] Digital mode power handling for KAT3

[Bill Frantz]

I have frequently used my K3 at 100 watts with FT8 and RTTY. I haven’t had anything which would indicate that components are getting overstressed (e.g. bad smells). 

Now, I don’t think I have given a full 100 watts when something isn’t connected in the antenna system, although the KAT3 does “match” an open antenna line. Since in that situation, it clicks for a long time before coming to a “match”, I tend to notice that there is a problem before applying full power.

Lots of components if heavily over stressed can go south in 13 seconds. Whether that is the case with the KAT3 is unspecified as far as I can tell.
