Hello Group?
I am looking for the components, tuning fork, frequency of 502.5,
532.5......802.5hz range for maritime radio beacons. If anyone share a
information about, who makes, where can I order..., I will be
appreciated very much.
Thanks,
HWLEE |

Musical tuning forks may get you close for some of the frequencies. They
should be available in frequencies 440Hz * 2^(n/12) where n is a whole
number (positive, zero, or negtive -- within reason).
For example:
A is 440.00Hz
A# is 466.16Hz
B is 493.88Hz
C is 523.25Hz
C# is 554.37Hz
and so on.
However, I'm having a hard time finding chromatic sets (separated by the
12th root of 2 ratios) that are anything wider than from 261.6Hz to 523.3Hz.
Here's a link:

You could probably trim them to get the exact frequency you wanted, but I'm
not sure how well this would work.
