Hi Mike,

I like your program. The small file size is nice (I have VB6 so don't need
the bulky runtimes) and the GUI is exellent. The only problem I see so far
is the sec. calc for number of turns and TPI does not seem to respond to the
additional space added input. My 4" coil is wound on a lathe at 40 TPI and
has exactly 800 turns. I also got error messages when I entered the spec.s
for the primary saying not enough turns for the required inductance. Then I
closed the primary calc. form, and after reopening it, everything was fine,
including the tap point within 1/4 turn of where it actually is. I must
admit I did not read the directions, just downloaded the app. and ran it
from inside winzip. (had to open the other two files so the apps. exe could
find them)

I have tried every TC program that has been offered so far, and IMHO, yours
is the hands down winner.

PS: am including the specs as tha progran saved them. Found no right click
menu with cut past copy, but ctl-c and ctl-V still work fine on the
textboxes, so that is cool anyway.
