[Elecraft] TX Equalizer Profiles

[Walter Underwood]

I collected a bunch of equalization curves from experienced operators on this list ten years ago. Some were weird, but there was a pretty good consensus. I chose K9YC’s curve as representative of that. I also included the curve from Heil, but that was one of the weird ones.

Just use the one from K9YC.
