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.

Hi LF Group,
soon I will have to buy a new kitchen and I wonder, if an induction
cooker is the right choice (regarding QRM!). Does anyone have experience
with QRM on MF, LF, VLF produced by an induction cooker? Which brands
can be recommended?
I already heard, that there won't be problems on 80m, but what about
lower frequencies?
I'm not yet QRV on MF/LF, but maybe in the future..
Any comments and experiences will be helpful!
