I believe in what I hear on the air as well, Earl. Rather than take
your word for it, I found several of the weakest signals I could find on
20 and 40m this evening--the kind of signals which are nearly covered in
noise and which aren't moving the S-meter. I cranked the Orion's
bandwidth down to 100z and tried various levels of DSP noise reduction.
They all produced better copy than without the DSP processing. In fact,
they made for nearly 100% copy of signals which were not 100% without
the processing. What could account for our differing results?
