Topband: End of a bias tee adventure?

[Tod Olson]

Is no one going to suggest that a ³gyrator² should be put into the circuit
instead of an inductor?

There was a W3 who had some of the diodes for replacements. They are
surface mount and small! Obviously, one wants them to have a very low
conduction threshold voltage. I suspect Tom can suggest some diode choices
that will work.
