I don't think it was entirely a "scam" on the part of Amidon. When you think about it, FT-240-31 is easier to know "Ferrite, Toroid, 2.4" OD material #31" is a lot easier to remember than "2631803802" :-) Similar in concept to using channel numbers for TV instead of frequency assignments -- it makes it easier on the users/viewers.
