[Elecraft] sidetone range

[O. Johns]

Dear Wayne and Lyle,

In the original specs for the K3
(and even now in the Tech Specs page: <http://www.elecraft.com/K3/K3_specs.htm 
 >)
the sidetone range was, quote, "CW Offset/Sidetone: 300-1000 Hz,  
adjustable."

But the newer manuals, and the K3 itself I presume, have the range  
limited to 300-800Hz.  I wonder why this was changed?  Was there some  
hardware or software reason, or did you just decide that no one would  
want a sidetone up to 1000Hz?

Now most people may not need a sidetone above 800Hz, but I do.  Here  
are my reasons:

(1)  I have a hearing loss at low frequencies.  I know this is  
unusual, but it is so.  It is hard for me to hear low pitches  
clearly.  (I know the arguments about lower tones being easier to  
separate in a QRM situation, but, alas, that is of no use to me.)
(2)  I will be listening to that sidetone a lot, and would like to set  
it at some exact musical pitch so as to preserve what remains of my  
musical pitch sense.  Now 440 is a perfect A4.  But it is too low for  
me to hear.  What I need is 880, a perfect A5.  But this is above 800.

Is there any chance that the upper limit could be moved back to  
1000Hz, or at least to 900Hz so that it would include 880Hz?

Thanks and 73,
Oliver Johns
