Re: Harmonic performance - SSB vs CW

Another aspect of filter design, and to reduce insertion loss, are the capacitors used and their characteristics. In my opinion (and some experience) Mica is the best but expensive, Polystyrene is second best but difficult to find, Ceramic NPO is third, and I'm sure there are exotic types out there too but they cost too much or are not readily available. You have to watch voltage ratings but not so much in the QRP range.
