[Elecraft] [K3] Noise Reduction Recording

[David Ferrington, M0XDF]

I'm still having trouble determining if what I hear is noise that NB should
get rid of. This is because I'm a relatively new Ham without the experience
to know what I'm hearing.

So I have made a recording on the noise and it is available from
<http://homepage.mac.com/davidferrington/FileSharing2.html>

I have recorded 3.740MHz in 5 second tracks with a tone between each change
of NR setting, viz:
    5 seconds of no NR, 200mS tone @ 700Hz
    5 seconds of NR F1-1, 100mS tone at 1400Hz
    5 seconds of NR F1-2, 100mS tone at 1400Hz
    5 seconds of NR F1-3, 100mS tone at 1400Hz
    5 seconds of NR F1-4, 200mS tone at 700Hz
    5 seconds of NR F2-1, 100mS tone at 1400Hz
    etc.

I have found no NB setting that affects this, I can possibly hear a very
slight change, but it does not cancel the noise.
I can do the same for the NB settings if people wish.

I would appreciate some feedback on this please, is this just broadband hash
in my urban neighbourhood from er, broadband and wall warts etc?

Mail me off list if you'd like me to mail you a copy of the file direct.
