Exactly Don, my point exactly, You DID miss the point. You DON'T understand why someone would want to do it. That's why you can't understand why he's asking for what he's asking. We're not all built out of stone. We don't all want to listen or send our CW at the same pitch all the time. If find that in Noisy conditions I like to lower my side tone down to 380Hz, yet when I'm in a casual QSO I find that I receive better at about 450Hz. When I have 2 stations that are close to each other, and I need the notch to do something for me that it doesn't do as well when I have the pitch set to a low freq. I like to have my pitch set up around 650Hz. It just depends on the conditions, the noise level, the stations that are in the pass band, and how I use the tools that the K3 has to deal with them. IE DSP, NR, NB, RF GAIN, Notch, Soon to be APF, REV CW mode, etc..... It's more than just my "comfort zone" when it comes to the IF pass band, or centering someone in it.
We don't all use our radios the same, as I'm sure you already know. For this reason, I DO understand exactly why this person would want to be able to shift his IF WHILE in a QSO, WITHOUT having to interrupt it with the side tone pitch freq. as he's doing so. I've had this happen to me on more than one occasion.
As for the Zero Beating, oh boy are you right. People out there have no idea that their side tone has anything to do with their IF Center. They all expect that you have your filter open up to 1KHz when they answer you... I can't tell you how many times people will answer me as much as 100Hz off of my IF center. But they can't all afford a K3 I guess. The new rigs these days don't all tell you when you're in the IF center. The ones that do pretty much have a little orange light that comes on, and most of the people that use these radios don't even understand why that's there.

He's asking that when you push the button that sets the pitch freq. that the tone isn't generated.. That way he can hear the person he's talking to while adjusting the freq. of his IF's center pass band area. Plenty of us wish we had this ability.. There are MANY times when I feel like I want to adjust the tone of the persons signal without moving it away from the IF center, and then having to chase after it with the shift knob.. His idea would do exactly that.
