I suggest you all try finding a copy of RadCom from a few months ago. There
was some very interesting research into the human ears response at various
frequencies relating to intelegibility of CW signals. And the human ear has
much more dynamic range in the 400 to 800 Hz area and thus that is why many
operators use that range and it's becoming more and more a standard.

Subject: Re: [Elecraft] CW-Pitch 600 Hz or 700 Hz or what?
This subject has been discussed on the TenTec reflector, too. I tend to
agree with K2VCO's ideas concerning the ear's ability to discern slight
differences in pitch better at low frequencies. Bill Tippett, W4ZV, really
got my attention when he divulged that he uses very low pitches (below 300
Hz) to copy weak signal DX. (Bill is one of the best in the world.) Ever
since I learned that, I've set my Omni 6 as low as it would go (400 Hz).
What's the range on the K2?
