 hi terry

I really like your gap design. I was going to modify my rq type gap to
improve the quenching, but i will try your idea first to get some
comparison. What is the rating of your power supply?. This gap looks so
much better for adjusting the voltage. thanks for all your invaluable
experiments and scope pictures they are really useful to throw at the
techys who dismiss anything more than three weeks old as old fashioned and
no longer relevant.
 You say you live at 5500 feet.  I gather  this is in the mountains. Is the
air always dry? I live at sea level in the UK and at the moment it is
raining, as it has most of this summer. I wonder what difference this makes
to spark length.
