Why not use HP pin diodes? I installed these in my IC-765 for the
bandpass filter section to improve 2nd order harmonic suppression. As I
remember, they were around $3-4 each. They were not readily available,
but we were able to find someone who stocked them (either Avnet or the HP
distributor - I forget now). These are the HP diodes mentioned in Dr.
Ulrich Rohde's QST series on "Modern Receiver Design."
