[Elecraft] KX2/KX3 operating tip: Creating a CW "sound stage" using AFX PITCH mode

[Peter W2IRT]

Think of it this way. Let's say that your default CW note tone is 500 Hz. When you're zero-beat with someone at 500Hz they're "right in the middle" of your ears. Equal signal left and right. A 750 Hz tone would appear in your right ear, and a 350 Hz tone in your left. As you move the VFO from where you are, tuning "up" the band, that 750 Hz tone would "slide across your head" to the left, and when you zero beat it, it's right in the middle. If you keep tuning in that same direction, that same signal would start to favor the left ear, and below a pre-set threshold, would appear only in your left ear.

I'd gladly pay to have what the OP is asking for as well.

Wouldn't taking the headphones off, rotating them 180 degrees and put 
them back on do the trick?  That way left would be right and right would 
be left.

Guess I'm too dense to understand the acoustic phenomenon.
