I continue to do research on selecting the correct ferrite for HF RFI
problems. What I have found so far is that it appears that Type 31
material is best suited for 1-30 Mhz. This is not the usual 43 or 77
material sold by most. 43 and 77 have a wider range but not the
impedance in the 10mhz range as 31. Before I go order up a bunch of
31 material stuff does anyone have any experience using 31 material?
Tnx es 73
