G3PLX included such a facility in PSK31 to allow for the gross errors seen on some machines - several Hz on a 1kHz tone in a few cases. There are enough highly accurate transmissions around for calibration, so if the cal factor can be saved (and doesn't drift too much !) one area of uncertainty is removed.
