Try more toroids in the stack and use close-wound turns to lower 
the resonant frequency, using the data for coax of similar size as 
a guide. If that helps, it's being radiated by the power cord, If 
it doesn't, it's probably being radiated by internal wiring. 

You might also try an RFI filter bonded to the chassis of the unit 
-- I have a box of some from HSC that you're welcome to try.
