My reasoning is that the noise had become equalized in a mixer, or some other non linear device, but that in itself doesn't explain why Rx signals from forward of the antenna are affected markedly more than from other directions.
It has clearly been demonstrated that the noise cuts in at a particular rev range, but also noted that it lacks variation with the revs. That's why, rightly or wrongly I looked at the alternator regulator. You have killed off that idea, so what's the alternative?
The Faraday shorted turn proposal currently doesn't rest well with me.
HF has said that the null effect is only forward, and it would need to be the same when going away from the Rx source.
