[Elecraft] W2IHY 8 band equalizer and EQ Plus

[Lu Romero]

Don, I never suggested that this be implemented by an analog
stage or in an analog fashion.  I dont know where you guys
are getting that idea!

AGC can be perfectly implemented in a digital environment. 
It would quantize the waveform and bring the valleys up to
the peaks, then hand them off to the clipper where the real
fun begins.

That's all Im describing!  It has nothing to do with a 12AX7
at all!

We have beat this to death enough, so as not to rase the ire
of Eric the Mighty Moderator, I now terminate my comments on
this thread.

If we want to kibbitz, we can do it off the list.
