Yeah and the external wire will act like an antenna especially if it's got the right length.

Very bad. Strange also because Apple usually gets their PSUs made by Delta afaik and they are as good as it gets.

It’s not very bad. Detectable signals is not at all equivalent to interference.

Folks need to relax. People actually experienced with RF wouldn’t worry about this at all, and the FCC is perfectly capable of doing its certification job.

Breaking squelch on a scanning radio in the general vicinity is pretty bad. It shouldn't be generating such strong RFI on VHF frequencies. I use 2m (VHF) handheld radios at my desk at home with like 5 computers around me, countless chargers (including a wireless charger just like in the article). There is never a time that my radios are stopping on RFI generated within my office.
When people ask for certification. The stuff you get on amazon now doesn't have FCC numbers. Or silk screening on the pcbs or components to identify them.

Also there was a possibly false tale of intel adding clock jitter years ago to spread the emi across a band to pass tests, and then forgetting to enable that jitter on production units.
