Default Fan causing MW RFI

I have a 6-months old Fantasia ceiling fan (mains powered, with 6-speed
reversible dc motor) which is causing a lot of interference on MW. FM
is not affected. The interference is there on forward or reverse
rotation, worsens as the speed is increased,, and appears on portable as
well as mains-powered radios.

I can return it to the supplier for replacement or refund, but it is a
bit of a rigmarole to remove and refit. All the electronics are sealed
in, and the only accessible wiring is to the mains connector. Is there
any point in trying some sort of screening or RFI suppression on the
mains wiring before I take it down?


I find it amazing you can listen to MW/AM in a "modern" house with all
that electronic smog and EMI and RFI everywhere


Just about everything has a SMPS these days, and often some digital
control. Can't say that I've ever had a problem with any of these before.

Anyway, is there a more nostalgic way to listen to 60s hits than on a MW
portable with a tiny speaker?!
