Having said that Nick, the centre frequency of a Navy Department Bureau
of Ships CV-89A in wide shift is 2550 c/s which with ± 425 shift makes
the tone frequencies 2125 c/s and 2975 c/s.
That's the great thing about standards, there are so many to choose from!
I've got a CV-89A in the museum that I would love to be able to use but
the discriminator frequencies don't fit with present day tone frequencies.
