[Elecraft] FW: CW Pitch Resolution

[Dr. William J. Schmidt, II]

Not that we have established the notes... maybe we can make it play "Smoke
on the water"?

Hi Folks:

The CW pitch resolution in my K3 seems to be 10 Hz per step. A recent
article in QST
spoke of 432 Hz as being a sweet spot frequency based on musical notes. A
quick search
on frequencies of real musical notes shows hardly any are at integer values.


Note -- Freq -- Wavelength

D4	293.66	117.
D#4/Eb4	311.13	111.
E4	329.63	105.
F4	349.23	98.8
F#4/Gb4	369.99	93.2
G4	392.00	88.0
G#4/Ab4	415.30	83.1
A4	440.00	78.4
A#4/Bb4	466.16	74.0
B4	493.88	69.9
C5	523.25	65.9
C#5/Db5	554.37	62.2
D5	587.33	58.7
D#5/Eb5	622.25	55.4
E5	659.26	52.3
F5	698.46	49.4
F#5/Gb5	739.99	46.6
G5	783.99	44.0
G#5/Ab5	830.61	41.5
A5	880.00	39.2

Could the firmware be changed for experimentation with this or is there an
easier
way to accomplish it with RIT or filter offsets?
