Your right, the program was doubling my cap as well and hence the new
tap spot.

Thanks,

Why would there be any change in the primary tapping?  If you don't
change
the capacitor in the primary, nor the secondary coil and topload, all
the
resonant frequencies would remain the same.  You might see a slight
decrease in frequency just from the increase in capacitance from the
more
and longer streamers.

Perhaps the model is assuming you are changing the primary capacitor to
make
it larger to take advantage of the larger charging current available?  A
doubling in current would imply a doubling in capcitance, which in turn
would imply an decrease of 1.414 (=sqrt(2)) in frequency.  To keep the
frequency the same, the inductance would need to halve (so the LC
product
remains the same.)  Changing the tap from 9-10 down to 6-7 would
probably be
in this range.
