Radio noise is often the result of unstable or unregulated power
conditions. I am having the same issue at home with certain effect
pedals.

I spoke to someone yesterday who said that the issue needs to be
addressed with something a little more industrial then something like
a power conditioner.

I haven't found exactly what will work safely and within a reasonable
persons budget.

If anyone knows any specific product please let us know.

Sorry I cant be more helpful.
