Maybe locked, but probably not in a 'integer number of cycles per
symbol' sense, more in the "derived from the same master 10 MHz
reference" sense.
All stations use the same data rates, but have different carrier
frequencies, and the carrier frequencies are the same ones we've always
had, which don't necessarily have nice ratios between them.
