Tony I watched your video on the scaning circuit,and I can tell you that it is not right.Your scope shows the voltage rising and falling,and not the frequency changing.Now I don't know where your taking the measurements from,but if it's right out of the scanning circuit before the primary,it not right.
When the scanning circuit is running ,you should see the frequency expand and contract horizontaly and not verticaly.
All I see is the voltage rising and falling,and not the frequency.
