He's absolutely correct. Many times I've posted a link to my tutorial
on the topic. I spent years learning how this stuff works, and months
writing it up. I won't repeat it here. Only the link. k9yc.com/RFI-Ham.pdf

I was reading the recent QST article RF Mayhem by WB8IMY. The author said to
avoid using snap-on ferrites for problems caused by HF signals as they
