Good thing I included the instructions so you could make your own, 
then.  Let me know if your results turn out significantly different than 
mine.  I chose the tones I did to be roughly centered on the noise 
spectrum I recorded.

I can think of a couple of reasons why a lower pitch might be desirable 
.... primarily the ability to better discern differences in pitch, but 
also because many hams find it less fatiguing.  I'm aware of hams who go 
down close to 200 Hz for contesting, but I'd bet a broad survey of hams 
would put the most commonly used pitches between 400 Hz and 600 Hz.
