7333.33 KC is one of the calibration points in the settings book. It uses
the 22nd harmonic of the 1 MC oscillator and the 3rd harmonic of the variable
oscillator.
The only connection I can come up with is that CHU was for many years on 7335
KC. But the difference would be an odd number, 1666.667 CPS. Maybe he had
perfect pitch. :-)
