[Elecraft] K3 just goes off - SOLVED

[Hisashi T Fujinaka]

What does the maritime industry use? Anyone work at Boeing who can tell
me why they (I think) crimp instead of solder? I thought I remembered
that it's because crimps are stronger over the long-term under
vibration. I could be making it all up.

I'm just curious if there's a reason or if people are just talking for
the sake of talking. I've had lots more solder joints fail than crimps,
but I've had crimps fail too.
