The unfortunate side affect should be a substantial fine to Sangean.

I’m looking through the online operating manual for a Sangean AM/FM radio I’m interested in buying,

“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.
