[Elecraft] Auto Notch Revisited.

[wa9fvp]

A feature that we added to the Hamblaster was something I called a Filter
Freeze button.  It was something I suggested and turned out to be very
affective.

It wasn't really physical a button. It was actually an on screen control
that passed a parameter to the Hamblaster telling the LMS algorithm to stop
up dating.  The LMS algorithm converged on the carrier and then stopped
updating it's coefficients .  It locked the auto-notch frequency and killed
the carrier without affecting the voice.

The Idea was to have a semi-automatic filter that you can press a button,
quickly notch the carrier and lock the null frequency and depth.  A manual
adjustable notch was too cumbersome and would required fiddling with the
frequency adjustment knob while trying to null the carrier.  


I would love to see this feature added to the K3.
