My circuit is very special. I think scientists should be interested.

So as to remove notch between upstream and downstream, I've connected by AnnexM. Following there is usual hlog and AnnexM hlog.

I suppose that my abnormal Hlog is caused by PSD masks for annex m.

I've contacted with Jonathan Stein. He says that large metal objects can cause coupling effects that cause impedance changes which can cause rolling changes in Hlog. But I don't understand. Can objects not connected to the cable cause impedance changes?

YES !  think of Contactless Chargers for mobile phones or Microwave Ovens. The phone say, takes power from the charger so in turn the charger's impedance must change to draw that extra power from it's supply.
OK ?
