[Elecraft] Re: Zero beat hint and why 800hz maximum?

[O. Johns]

Dear Wayne,

A pitch of 880 Hz is an exactly tuned A, twice the canonical 440 that  
orchestras are tuned to.  Musical people might like to use 880 to  
avoid upsetting their sense of pitch by hearing an off-key sidetone  
all day.  Also, 740.0 is within a fraction of a Hertz of a correctly  
tuned (well-tempered tuning) F#.  So there is good reason to have the  
increments of sidetone pitch be 10 Hz rather than 50 Hz.

I'd suggest that, if the hardware registers permit it, the firmware on  
the K3 should allow a sidetone from 200 Hz to 1000 Hz by 10 Hz  
increments.

By the way, I find on my K2 that setting the sidetone readout to 730  
actually gives an audio pitch of 740 Hz.  But setting to 440 actually  
gives 440.  This is the result of granularity in the registers, I  
assume.  On the K3, the actual pitches should be within 1Hz of their  
settings, or so I hope.

73,
