Alan, When it does become a usable function of the P3 I am sure you will see a spike in sales volume.
Till then I can get along without it.

At N1AL, I discovered that I had way too much bass so I adjusted the K3's TX equalizer to make it flatter. As Joe says, it does not include the effects of amplifier distortion. And as Knut says, the signal level depends on random leakage through the mixer and PIN diodes, so it varies with band, drive level settings, and sample-to-sample variation of the particular K3. There's no guarantee that there will be enough signal available to be useful. That's the main reason I resist making it an "official" feature.
