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!
