[Elecraft] K3 Audio

[Bob McGraw K4TAX]

I will amplify Jim's and Wayne's and Lyle's comment regarding audio, 
attenuation of a frequency or frequencies produces far superior results 
to boosting a given frequency or frequencies.   We have become 
accustomed to "boost this" and "boost that" when in fact attenuate this 
and attenuate that is the better option.   One just has to understand 
the spectral components of audio to figure out how "this and that" applies.
