K3 Equalizer comment

I'm not one to get mushy about my things. I try to remain objective, but
I want to make the following comment;

Because I have a pan adapter (P3), I was asked to help a ham get the
transmit audio on his new import equalized. What an experience!
It made me realize what a fine equalizer design the K3 and K3s has.

And hello to new K3s owner Ken Arck. It's been a few years, and the
controller is doing fine. I wish my K3 was an 's' model. Enjoy!

Dick, n0ce

How did you use the P3 to do this?

Re: K3 Equalizer comment

By looking at how his signal filled out the voice band in the waterfall,
and also the pattern of it on the display. It is a crude test using a
person's voice. Audio reports were the final test. He wasn't able to
adjust it by monitoring his own voice.

It would be better if the transmitting station had something like an AF
generator audibly coupled to the microphone to do a freq run within the
voice band at a constant audio level.

Re: 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.

Re: K3 Equalizer comment

Yes, I have a narrow span like that programmed into one of the P3
buttons for quick selection. His audio was centered around 500-600 Hz.
Several guys with pan adapters ultimately tried to help him. I signed
off and let them work with him. I heard him the next day and his audio
was better but still room for improvement. Everyone had been giving him
bad audio reports and he sounded choked up with disappointment. It is a
new radio. Enuf said about that. We have it good.
