I played this weekend's contest from a friend's house in the San
Joaquin Valley. Had a good time; we worked 104 countries between
us, including seven all-time new ones for me.
He had recently completed building the DSP unit that was described
in the September, 1992 issue of _QST_. We used it quite a bit this
weekend, and boy, was it great!
It has two options: it can either subdue high noise levels or tones.
(I guess if you have both at the same time you take out whichever
is worse.) (Evidently it can also act as a CW filter.) And unlike
a notch filter, it doesn't take out any of the signal you want to
listen to.
Now if only it could be taught to remove QRM....
