[Elecraft] [K3] Noise Blanking, all-mode squelch- any strategies for settings?

Something missed in this discussion.

When you change a NB/NR setting, don't expect a instantaneous change.
Count to five and then conclude whether a setting change helped or not.

In some past posting, this was pointed out by Elecraft.
