[Elecraft] K3s Receive EQ

[Bob McGraw]

Regarding "quick on the fly adjustments", I don't view an 8 band EQ as 
one that would have quick on the fly adjustments.

Depending on your choice of sidetone frequency, the selection of RX EQ 
frequency and amount of attenuate and boost would seem adequate.   I 
agree with what Jim, K9YC, says about this.  In order, attenuate first 
and boost last.  There is less phase distortion.
