[ARC5] BC-455 IFT - measurements

[Dennis Monticelli]

Perhaps someone can comment upon the degree of coupling between the two
coils.  If the coupling is tight, then the capacitance's on both sides will
interact.  Adjusting one side will pull the other side into pretty much a
single resonant circuit.  Perhaps that was what was intended.

Having a dual resonant transformer translates into deliberating reducing
the coupling and accepting the modest signal loss that goes along with
having two Hi-Q resonant circuits lightly coupled.
