Hi All,

Just another thought about "Zapper" schematics . . .  for those
who are not able to build the more complex circuit just posted,
how would you like a simplified version, single frequency, that
was designed for use while traveling?  That circuit runs from
and nominal 12 VDC source.

PS:  Maybe we'll be able to make a variable frequency type if you want?
