[Elecraft] K3 Harmonic Distortion

[NZ0T]

This may be a glass half full response but being an old hearing impaired guy
has it's positives:

1.  Ignoring XYL when needed and excusing it by pointing to hearing aids.
2.  Sleeping like a baby every night with said hearing aids removed.
3.  Not hearing any distortion in my K3.

Life is good
