It is interesting that they warn you about that... but a company making a radio
should at least try to choose a wart that is quiet.

Subject: [RFI] A note from Sangean about switching power supplies
I’m looking through the online operating manual for a Sangean AM/FM radio I’m
interested in buying, and I came across this little note in the Cautions
section. I didn’t know about the “background” cited, and I do find Sangean very
responsible to print this.

VERY IMPORTANT PLEASE READ
Sangean suggests that you keep your AC Adapter at least 12 inches away from the
radio while listening to the AM Band.
Your Sangean Radio is powered by an AC adapter which is a “switching” or
“switch-mode” type. The DOE (Department Of Energy) has a Federal mandate
requiring all manufacturers to use this type of power supply. This newer power
saving technology has the unfortunate side effect of causing interference to
the AM radio band.
