"Then subtract the resulting omni signal from both prefiltered ORTF signals."
Why subtract?

Hello everybody, I'm an unlucky owner of a S502MKII from 2020 with uber high sensitivity to radio magnetic interferences (see spectrum capture attached). I also own a S502MKI wich doesn’t have this problem. My setup is clean, simply switching from the MkI to MkII brings the interferences. I can manage to lower/avoid those interference on the MkII by adjusting mic placement and recorder position relative to mic, but it remains unusable for me.

@MicUlli I would be interested in 2 boards, do you think the new boards would solve the interferences issue on MkII?

That's exactly what I read on Thomann customers' reviews... interferences with MkII and none with MkI... But I guess it comes from the circuitry, not the capsules, so @MicUlli 's board should solve that

Thread pitch = 0.5mm ! Thread outer diameter = 19.3mm
Finally managed to measure it today…

Which body ? MkI or MkII ?

You've just bought a mic for around £140, which compares favourably with the Schoeps $2500 item. You now wish to spend the Lord knows how much cash to convert your mic into something it never was. Just get on and record something and enjoy the mic for what it is - a very useful, very cheap mic. (Or start your own microphone company, if that's what you'd rather do!)
