I'm thinking about building some narrow band filters (as opposed to a bandpass
filter that
covers an entire band) for use on Field Day. The object is to minimize
crosstalk between CW
and sideband stations on the same band. Has anyone tried this? Is it practical
to get enough Q
to pick up enough rejection to make it worth the trouble? Certainly 80/75
would be the most
practical, since it is the greatest percentage bandwidth. Is anyone making a
commercial
product?
