Hi Dave,

I think Paul has indirectly answered the question about the two paths (ie,
electron path and EM path thru the air).  The distributed LC (electron path)
and the lumped LC model (the EM path) give the same answer.  There is only
one fundamental resonance.  I believe the two frequences result when not in
tune.  Then you have a forced response (primary frequency) and natural
response (secondary frequency).  For this purpose I'm neglecting the effect
that coupling between two tuned circuits has on each other's resonant
frequency.  Chime in Paul if I didn't paraphrase this correctly.
