Obviously this isn't going to be affecting a huge number of people in 2021, but if you listen to AM radio (I'm a bit of an anorak for Radio Caroline so I've been trying to pick that up) it's amazing how much interference modern devices give off. The monitor I bought last month absolutely wipes out 648 kHz, and Apple's Magic Trackpad 2 is a pretty bad offender as well.
