The wires would not vibrate at hundreds of kHz...
How critical is the tuning? What happens when the system is
out of tune? I imagine that the effect appears and disappears gradually,
as it is caused by a series of "bangs" producing always the same
waveform on the coils.
A similar effect can be observed at higher frequencies too. See
the classical experiment of the "Lecher wires". With enough voltage
for excitation (connect the wires in parallel with spark gap), the
effect appears as corona across the wires.
