[Elecraft] K3 Suddenly no power out / high SWR on 10m only

[Fred Jensen]

Wrong antenna selected on that band?  I guess you'd have to have a 
separate receive antenna since you say it hears OK.  Similar goof on me 
when I was new to the K3.  Everything was fine everywhere except 30m 
where the SWR was 99:1 and no output.  Talked to Gary, he finally said 
he'd elevate it to Wayne, who asked for a time to call me and he did. 
Said, "Let's start with the easy stuff.  Which antenna is selected."  I 
selected ANT1, and of course everything was fine.  They're remembered by 
band.

I'm not holding my breath for a call from Mr. Yaesu-san if my FT-847 
quits. :-)
