All Elecraft radios that I know about display the transmitted carrier
frequency in CW and the suppressed carrier frequency in SSB mode.
Your sidetone pitch setting is related to properly tuning a CW signal
and knowing its frequency. If you tune the received signal to a pitch
the same as your Sidetone pitch (that is zero-beat with the station),
you will transmit on the same frequency as the station you are receiving
(with RIT and XIT turned off).
Turning RIT on will not move your transmit frequency, but will change
your receive frequency. Turning XIT on will not alter the receive
frequency, but will change the transmit frequency. I think of RIT or
XIT as a 'mini split'.
To add a bit more to the mental girations, the receive frequency
displayed IS changed with RIT, so in order to determine your transmit
frequency, you have to add or subtract the RIT offset (or just turn RIT
off and you will see the transmit frequency in the display).
With RIT on, what the display is telling you (assuming you used RIT to
tune the station to zero beat) is the carrier frequency of the received
signal.
Simply changing the sidetone pitch setting without tuning the received
signal to that pitch will accomplish nothing useful IMHO.

I'm having a hard time getting my head around this. My radio is on
3507.02 USB-CW, with a 500 Hz Pitch setting. I change the Pitch
setting to 300 Hz, and the display still reads 3507.02. What is this
frequency? The suppressed-carrier frequency plus the CW pitch? Does
that mean that when I change the pitch, the radio is actually moving
its frequency a little bit?
A somewhat related question. Same setup, but listening to a signal on
the air. "Beat note" is ~500 Hz. I turn the RIT so that the received
signal is lower frequency - say 200 Hz. I transmit. What does the
station on the other end hear, assuming he is also using USB-CW? Does
my "beat note" go up in his receiver, or down?
