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 https://www.arrow.com/en/products/5943000301/fair-rite-products A nextion display really benefits from them.

These on power cords and baluns. https://www.arrow.com/en/products/5943002701/fair-rite-products
and these around coax with PL259. https://www.arrow.com/en/products/5943003801/fair-rite-products

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.
