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

[Kurt Pawlikowski]

Don, Et Al,

    Just a note: While I am fairly musically inclined, I find that most 
rigs (including the KX-1 and FT-757) produce a non-sinusoidal note which 
I can't seem to consistently get my brain around. I find myself going to 
spectrum programs a lot...

    Regards,
