I've never run into an external power supply that didn't need some work to
optimize it for noise suppression. Even the AOR7030's power supply benefited
from a little extra work. For about 2 dollars worth of components, any power
supply can be made to be quiet. Connect .01uF caps across each of the
rectifier diodes, and bypass each leg of the power transformer's secondary
to ground with 1uF non-polarized caps to ground, and you are all set. Make
sure that you derate the 1uF units to at least twice the peak to peak output
voltage of the transformer.
There is no such thing as a good wall wart, from Radio Shack or anybody
else. Even the relatively expensive Power One frame supplies need these
add-ons. The reason that these manufacturers don't do this in the first
place is because they don't have to subject their units to stringent EMC
testing.
I hope this helps.

This "thing" is NOT a Grundig!
Grundig is out of buisines for years and years, sadly enough.
It's just companies playing games with "good old brand names".
