At what frequency and signal level are you calibrating? I haven’t
noticed this here, but 10Hz may be within the resolution of the way we
read the peak for the text readouts below the display. I’ll have a look.

Eric, I think I may have reported something similar before. Some random
amount of the time, I find that in my digital work, the other station,
when I respond to their CQ, actually tunes me a bit off the original
frequency and by a small amount (probably 10Hz, though I can't measure
it). It does not seem to happen every time, but on MixW I surprisingly
often have to open a second window (as if I were monitoring a second
station) to do the QSO and see the DX' signal has moved, usually down, a
small amount as shown on the "waterfall" display on MixW as well as the
need to open that extra window.
You might explore this situation using PSK 31 with some suitable plug-in
like MixW or Ham Radio Deluxe.
