Hi again,

thank you for so many answers!

Special thanks to Eberhard, DL3ZID, for the detailed spectrum 
screenshots of different QRM sources and also to Alan, G3NYK, for the 
link to the excellent article about QRM from a NEFF induction hob.

I see that there will sure be some QRM from an induction cooker. But 
mostly, it will be off >23 hours/day - and I can decide about it myself. 
Indeed, the advantages of an induction cooker mentioned by Dexter are 
important.
Maybe I will buy a little extra ceramic glass cooktop, to have a 
low-noise backup cooking solution :)

The answers also show, that in reality the major problem is QRM from 
other electronics which runs 24/7 and not only before lunch. So we must 
carefully chose a "quiet" solar (PV) inverter if we want to install 
solar panels on the roof, for example. Or we'll have to modify it with 
additional filters...

After all, it's even harder to prevent QRN = Neighbour-made-noise. 
Hopefully they don't use PLC or something like that!

And yes, Stefan, I live near Nürnberg and I know Markus and his VLF 
grabber. I will tell him to check the grabber for signals from my 
induction cooker, when it's active the first time. If he can prove the 
reception from MY(!) hob, I will send him a QSL card and invite him for 
lunch :) But it will be hard, it's more than 30 km.

73,
