Hello list,
 
Another scientific curiosity question:  Has anyone experimented with a sync RSG
designed in a SPDT configuration?  By that I mean the cap is connected to the
center pole of the gap-"switch".  The pig (or other HV transformer) connects to
one pole, and the TC primary connects to the other pole.  There would thus be
two gap presentations per bang.  The first presentation only charges the cap. 
The second presentation discharges the cap into the primary tank, completely
isolated from the power source.
 
This avoids putting the gap across the pig, which perhaps lets the gap run
cooler (no 50 or 60 Hz power arc), and may lead to higher efficiency and better
quenching.  This would also aid in keeping nasty RF out of the pig, and perhaps
would reduce the need for RF filters.  On the other hand, the gap losses are
now twice(?) as high per bang.  This is probably a lousy setup for NSTs as
there is nothing to keep the NST voltage from soaring too high.
 
If someone has tried this, please let us know the results.
