The 522-509 is an odd creature. There are two pass and two notch on the
transmitter side, and one pass and one notch on the receiver side.
Discussions about this duplexer came up a while back on this list -
maybe it's in the archives? I think Bob NO6B posted measured
performance of one he put on the bench.
