Bud has provided wisdom but I wondered if anyone else has suffered the same symptoms and might have a cure.
I have a turbo 80hp.
So it started with a crackle in the deadset that rose and fell with engine power.  This occurred in mid flight after a normal mag check.  Prior to this the Dynon Skyview had been without abnormal noise.
On landing I found that the switching off the left mag silenced the crackle and switching off the right mag made the engine run rough.
The CDIs have two "in" connectors from the pick ups and two "out" connectors to the coils.  So I swapped the "in" connectors between CDI and the "out" connectors.  Also I tried to start the engine with only one CDI connected to one out connector.  Both CDI work with both in-connectors but both only work with one "out" connector to the coils.  When the CDI is connected to the "wrong" coil the engine wont start.  This leads me to the conclusion that I have a problem between the CDI and the plugs.  In other words I have a problem in the coil system or in the HT/plug area.
Agreed?
If so, what is my next step?  How do I test the coils?
