Mike,

The comments you have attributed to me in the above post
are in error. You mistakenly copied another's comments and
put my name in front of it....... Not a problem for me,but
I get into enough trouble on my own without having to catch
any hell for other people... (grin)

Have any of you ever done this and how did it work out for you?

Jeff, I haven't tried this method, but one rule of thumb I have
always
believed in is:

"No matter how much you shift, limit, amplify or divide noise, it still
ends up as noise"

The only effective way I have ever found is to narrow the bandwidth
around the signal until the signal starts to get degraded. If done
digitally, it can be done by digital processing, but that changes only
the technique, not the principle...

So, while I would really like to try out some of these "improved
methods",
I am not confident enough in them to spend a weekend wiring together
some hardware.... In my younger years, I probly would've, tho....

Personally, as a CW operator of some 45 years, I have found that my
ears/brain does a lot better job of filtering than one would suppose,
especially
if I am copying some standard message where I sort of know the words
the other fellow will send. I only need 2 or 3 letters per word to
fill in
the pieces with devastating accuracy (grin).....

But, good luck on your efforts. If you do build up something, please

come back and post it here. I am sure that there are many
experimenters who try something like that if someone thinks it shows
promise..... But, please, take some actual measurements. And with
S/N ratios of around the 0 db level. My ear copy can still pick those

out, and many of the "processors" can't deal with noisy sigs in that
region....they tend to fall apart when anything below tangential
sensitivity is received....

It appears everything after "Andy writes:" was written by you. If it was
written by someone else, you did not indicate so.

It also appears the Period key on your keyboard is sticking and producing
too many periods. I have gathered the extra ones and put them here in case
you run out and need some in the futu
