Hi John,

What are any of the negetive effects of sputter mode?  Ive gotten my coil to 
work much better since i last posted on the list.  Im at about 2.75" arcs 
and nothing is really going wrong(exept no 6" spark yet).  I do notice the 
frequency changing alot when i play with the arcs.  If you could tell me a 
little more about this type of operation that would be helpful as im still 
trying mew ideas with this coil.
