Ferrites

Do radio amateurs develop a desire to go ferrite hunting? I’ve often wondered this. Many years ago when I used to go to radio rallies – this is when there were some close to here – there were always people wandering round examining various torrid and such. I never questioned this but always witnessed it. And I seem to have joined them! I now have four T130-2’s, one of which will be a 9:1 un-un and a box of assorted toroids on order to see if I can shut the hash up from a couple of wall warts. This is since I got my license, so it must be catching.
