ALAN,

If you are having "Noise Problems" using an ACDC Adapter with
a 'portable' Shortwave Radio.

First "Test" your AC Power Outlets for proper wiring and Grounding.

Often an 'incorrectly wired' AC Outlet or 'poorly grounded' AC
Outlet can be the "Source" of many AC Noise related problems.

Cheers RHF, I shall test the adapter, but how do I check that the "ground"
is sufficient, or how can I improve it please.
Thanks
Alan
