[Elecraft] DSP and CW?

[Bob Tellefsen]

Chris
There are two actions I would recommend.
First is a rotatable receiving loop to help reduce
local noise.  The best way to reduce noise is to
prevent it from entering the receiver.  It can be
tuned or untuned.  If tuned, it will be more
sensitive, but limited to one band.  If untuned,
it will be a bit less sensitive, but you could also
use it on 80m.  
Second is adding the KDSP2.  It will lower your
apparent noise by two means.  The first is the
narrower audio filtering which lets less noise
pass.  The second is the DSP noise reduction
algorithm which will improve your signal to noise
ratio in recovered audio.
Use both of these together, and you should see
a distinct improvement in what you can hear.
Good luck and 73
