[Elecraft] Regarding the K3 and high QRN levels

[Bob Cunnings]

Have you looked at page 25 of the latest manual?

http://www.elecraft.com/manual/K3_Owner%27s_Manual_Rev_D7sm.pdf

NB and NR settings are explained there.

Also, regarding NR settings, this was posted a while back by Lyle:

in a discussion of changes to NR being made at that time (affecting
settings F1-1 through F4-4, the fewer taps, the more "aggressive").
However there has been further change since then (e.g. the "mixed"
settings described in the manual were restored later) so that
explanation may or may not be current anymore. The manual plays it
safe, only saying "In general, the higher the number, the more
aggressive the noise reduction." without being specific about the
meaning of the 2 digits in the setting.
