hi jim
        hows things? anyway the problem may be that the gap between the
stationary electrodes and flying electrodes is too wide
on a rotary you want a narrow gap as there is liitle time for the voltage to
build.
this sounds identical to what i did with my first gap.
also jim do not use an asyncronous gap on an nst it will kill it fast
epsecially below 400bps(big surging probs)
cheers
