Hi Dr R,

Is the effect one of two I mention below?? or is it a third 
mechanism??  If it is a transmission line effect, can you explain why 
removing the shield fixes it and why proper termination 
doesn't???  If a resonant charging effect, can you descibe the L that 
the coax capacitance is resonanting with, the resonant frequency, and 
how this works???   If a third mechanism, I would like to challange 
you for the benefit of all the readers here to give a quick synopsis 
of this effect :o)).

Knowledge is everything and sharing it is golden.
Gerry R.
