I havent got to play with it yet,I hope it does help .Ive finally got a soldering iron and a desoldering iron so ive been robbing parts.This software acts like its going to be complicated with the trial version,if you can get a core figured out please help us out with this program.The guy in the referance link with his MOT shows his project and the effects of a gapped core wich was nice and informative.Stans VIC picture shows a rather large gap doesnt it?
