Elecronic question ???

[machinemover]

I enjoy XM radio better then the factory installed serius radio, I hook directly to the aux input connivently located on the face plate of the radio. I have developed buzz. This is generating from my ac/dc convertor box, I know this because if I turn the box off the buzz goes away. Is there a filter I can add somewhere to eliminate the buzz?

Yes, there are noise filters.



I have this one-



There are others. Just used that one as an example. www.JCW.com has some, too.



How well is the convertor grounded? Could be part of it as well.
