[Elecraft] [K3] Issue with HI CUR on 12m

[Bill Coleman]

I’ve had other problems with this antenna when the 17m traps broke down about three years ago. 

Looking back at my station notes, I’m wrong. It wasn’t RG-313, it was RG-303. Sorry for the error. This is a small diameter (0.170”) coax with a solid teflon dielectric.

Perhaps there is a flaky connection somewhere in his system.  I had a lot of RF feedback problems with my K3S when using a corroded station in the Caribbean but no current warnings.
