[Elecraft] K3 Equalizer comment

One of the first things I noticed after getting the P3 and poking around 
the phone bands was how frequently a station's audio was concentrated 
right next to the suppressed carrier.

K9YC helped me set my TX EQ, and the goal was to cut the lows [next to 
the carrier frequency] which consume a lot of the RF power and 
contribute little if anything to intelligibility.  With a 5 or 6 KHz 
span, the display is very striking and signals with a desirable spectrum 
seem to be a bit rare.

I don't frequent SSB very often, but when I do, usually in an NAQP or 
Sweepstakes, I regularly get unsolicited "Great audio" comments with 
Jim's settings.
