Found the same thing with an Apple iPhone charger a couple years ago. Apple have improved now. And yes they are often little switched power supplies.

I have been experiencing an arcing noise all over the vhf sat sub band and the 17m band for months.Finally decided to look for it.As soon as I walked out the door with H.T. in hand, it disappeared. Searching the house found it to be both Verizon phone chargers.Unplugged them,problem gone on vhf and 17m. They must be mini switchers.
