i have wrote twice - "can`t find reference right now, but will do it if
needed.", so why just don`t ask a link? stchs : )

can your simulator model this situation? this software is downloadable,
GNU-able, can i compile it for myself?

do you really suppose that his coils were such horrible quality or
were coupled well below 0.1? imo unlikely, and you can check his k
very easily.
