Default Odd humming issue

I have a feed out of VA Beach and I have recently had an issue.

I have a handheld scanner (Rad shack- pro-97) and I have wall adapter instead of the batteries but when I plug in my aux in cable with the wall adapter plugged in I get a humming noise. But if I unplug from the wall and use batteries its fine. I have tried different outlets from where the computer is plugged into but still has issues. any ideas? Is it a grounding issue?

Thanks for looking

It hums with the adapter plugged in and it doesn't hum when it is not plugged in, the process of elimination would lead me to believe that you may have a bad adapter.

Do a google or a search here at RR for "ground loop isolator" and you'll likely find the solution to your problem, as far as the audio hum goes anyway.
