How can someone have a spark gap running at 200/240 BPS (50/60 Hz). A 50 Hz mains waveform only peaks in two positions in a cycle. The crest and trough. Surely one set of electrodes will align when the wave is at zero. I have heard of guys running at 400 bps on 60 Hz. Isn't that terribly inefficient. It would just pull down the secondary voltages when the primary caps are only half charged.
