In my search for gear and doing things myself I came across this great link! www.seits.org/duplexer/duplexer.htm. It always seemed people think duplexers / resonant tuning cavities use magic or something. That site breaks them down for you and explains how to build one. I'm in the process of building one for the FM band. Obviously a band pass filter is basically a duplexer more or less. No real need for resonant cavity style one unless you run over 1kw and are crazy like me But really cool info none the less... Just wanted to share something I found useful...
