Thanks for the links. I bought those exact ones when you posted the link. Yes I bought a pack of ferrites once thinking I only needed a few and ended up using the all and then needing to buy more. :)

I have found it interesting that toroids work when caps and coax don't work. Toroids are my go-to for rf noise.
I use these internally in radios A nextion display really benefits from them.
These on power cords and baluns.
and these around coax with PL259.
I bought 25 of each and thought that should last me a while. Ended up using almost all in 2 days. Shack noise when down a couple of S units. Wall worts have been particularly bad.
