Hi Steffi,
Their switching frequency is above the audible range but not to far of,
to keep the switching losses low. But certainly a switched high power
source which will have a load of harmonics.
Avoid it of you can, especially when you are a radio amateur!
If you qrz.com entry is correct you're living in Nürnberg. I know
someone else on that reflector who's also living there and he is
operating a VLF grabber which could then detect when you prepare a
Schweinebraten. :-)
Another consideration is the life time. In our western throw-away and
buy new society i would expect that the life time will be less tahn 5
years maybe. The old models may behave different, because they are old!
And after all, for what do you need it at all? Is there any real
advantace? I just see it is fancy and you might need to throw away your
old pots and buy new ones, which is of course recommended.
If you look back in time, have you been unhappy with your old cooker?
And do you think you will be more happy (not just in the first weeks)
with the new one?

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!
