Well it's good that I've got people looking at this.
So far there is one post that just touched on it,but didn't follow through with what they said.I don't think they realized what they said.I won't say who it was,just to keep this topic going and keep everyone thinking.
It is a very simple reason,and you will all be surprised that you didn't catch it sooner.It is mentioned in the papers of Stans in several places,but you just tend to read over it,because you think he's talking about something else.Everyone thinks this way.
Alot of what you have said is true on how the circuit works,but have not touched on the reason for the gating frequency.Some of your reason aren't right,it really is simple what it does.
So keep the ideas coming,this is good.
