[TowerTalk] How to check trap resonance

[john.brewer at us.schneider-electric.com]

Can anyone suggest a workable method of determining the resonant frequency
of a set of traps off of a Cushcraft tribander?  I've got a working GDO, but
cannot find a dip with this configuration.  Perhaps its my method of coupling
the GDO to the trap. I've just been placing the GDO coil nearby the feedline
end of the trap as it sits on a wooden stool.

Anyone have any tried and true methods for doing this?

Thanks
John
