[RFI] A note from Sangean about switching power supplies

[Dave Cole]

I took a quick scan of this, and did not see anything about RF emission 
standards...  Hope I missed it...

Wouldn't it have been nice had they included RF emission standards along 
with the concern for CO2, and power use standards...

73s and thanks,
Dave
