Unless you're using APF, in which case a few Hz might make a difference. Like others, I don't buy the musical CW pitch theory either. However, the pitch of a CW note IS important, and there may be different optimum pitches for various different reception conditions (assuming your hearing response is not limited to a single narrow range).
It would be very useful to be able to adjust this pitch in an interactive way. That is a feature I wish the K3 had... Say if you have tweaked a signal to optimum in a narrow filter: it would be nice to then simply adjust its pitch for optimum readability. Unfortunatey. if you do this by changing the VFO/RIT, the signal is moved off center or out of the passband entirely. You could use the PITCH control: however, when it is engaged you can't actually hear the particular signal you are trying to optimize, only the loud sidetone. It is a bit of a guessing game, switching PITCH on and off to find the best tone for the signal. It would be a bit like having the signal muted every time you try to adjust the af gain. Not very useful. 73, Drew AF2Z On Sat, 19 Oct 2013 14:36:37 -0700 (PDT), Al W6LX wrote: >A few Hertz either way in the CW pitch not only doesn't make a lot of >psychoacoustical difference, but is hardly perceptible unless you have >near-perfect pitch, and even then isn't necessarily a problem. > >Changing the pitch probably has more to do with the self-resonant frequencies >of your speaker enclosures or headphones, and room.
