[Elecraft] K3 goes deaf when set to 12W or more

[Ken WA8JXM]

I had a similar problem years ago.  Apparently a not-close lightning bolt
damaged the tx protection.  Elecraft Tech Support was very good in the
diagnosis and suggested I could do the repair but my skills are from the
vacuum tube days so I sent it back to Elecraft for repair.

I suggest you contact Elecraft support.

Good luck,
Ken WA8JXM
