[bars] excellent RFI and noise reduction treatises

[Andy Wallace]

Recently I found the following PDFs dealing with using ferrites and filtering for noise suppression in ham radio. If you enjoyed W1HIS’s presentation last year at BARS then you will find these of interest. The level of knowledge and detail is amazing. Read the first linked PDF for the best overview. 

K9YC has done a great service by working on these!
