I just now skimmed over the QST May and June 1998 band pass filter articles by W3NQN. I only understood a little of Ed's design but am struggling to learn more. Copies of the 2017 ARRL Handbook and EMRFD (scanned reprint) will soon be on my desk. I am still thinking in terms of broad function blocks. Do y'all think a set of Ed's filters between amplifier and antenna feedline would take care of the spurs / harmonics / mean nasty things from a uBitX or a Minima?
