My first thought was, is it really a government law saying that they
MUST use that type of power supply?

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.
