Hi,


The measurements show irregularities at the HF output.
This can be tamed considerably by using a RC network across the primary side of the OPT.

Ideally you'll need a scope and an adjustable network to dial in the right values.
Once you're done those parts can be replaced with a fixed value R & C network.

Cheers, 😉
