Hi Ed, Jim, all, 

You know, I wonder if this isn't the case with most or all 
pole pig systems. I think someone else? may have men- 
tioned that with a pole pig type transformer, it dosen't seem 
to make much difference in the output spark length, whe- 
ther the RSG is synch or asynch (assuming a reasonable 
bps rate for the asynch vs. the cap's size). I can't personal- 
ly speak about synch systems as I've only had experience 
with asynch with my pole pig system. I think Kevin Eldredge 
in OK runs his huge 24' sparker synch at 20 kVA input, but I 
don't know if he tried asynch first? It would be intersting to 
try building two  pole pig sytems identical to each other in 
every respect, except for one being synch RSG and the other 
being asynch RSG, and to compare the difference in the out- 
puts, if any. I don't have the facilities (and money) to try this 
myself but maybe some better equipped and financed list 
member(s) could work on this? How about it Geek Group :-)? 
I would personnaly be interested in the outcome of such a test.

PS - My apologies if someone else has already tried this.
