Hi Richard

We have never met and as I am new to the Tesla List I was surprised to hear
of your dissapointment with the spark lengths shown by my JHCTES computer
program. The JHCTES spark lengths were obtained from test data provided by
coilers like you. The spark lengths are average lengths and it is obvious
your sparks are better than average.

The JHCTES program uses 46 of the major Tesla coil parameters as inputs and
outputs. I have had many favorable comments regarding the program. What are
your comments on the other parameters of the program? I would be willing to
change the program if additional test data on other parameters warrants the
revisions. I would be pleased to send you a complimentary copy for your review.

Thank you for your interest in helping me keep my computer program and books
up to date.
