The K3 NB has lots of tweaks. Depending on the modes you use, it might
help in some situations.

OK, kind of what I was thinking. So either go on search for noise
source or try reducing the noise at the receiver. K3 NB does not
improve SNR on 6m.
On HF noise varies: 80m its S7 from an inverted-V; on 20m its S3 from a
yagi (both have baluns).
6m noise at S5-S7 is the most troublesome
While it is unlikely to make any difference, if you can source these
ferrite sleeves in the USA they are excellent value and perhaps worth a
try. A pack of 5 cost about $1.50 plus shipping and tax (£1.15 + tax in the
UK). Two packs (10 sleeves) should make an effective choke for 6m and will
slip
I don't see how a common mode choke would help in that situation. If the
noise changes that dramatically depending upon where you have the
antenna pointed, that strongly suggests that the noise is being received
by the antenna and is not riding on the shield of the coax. If it is
received

If it does, something is very wrong in your shack, like bonding. What
DOES
I primarily work eme so band noise is a prime enemy of weak signals.
I was reading the comments about combating mic noise and wondered if

one direction
