[Elecraft] DSP problem

Thu Dec 4 23:22:01 2003

Thanks Lyle,

It is more like a course phase noise (for lack of a better term).

I just checked at all my components and the solder is good and everything is
in its right spot :)

Beyond that I can't add much !  I was pretty impressed how much noise the
DSP removed until I figured out it was causing it.  Kinda like calling my
wifes mixer a DSP audio filter. It is good at removing noise too. When you
shut it off  ;-)

73,

Rich
