Steve,

Sorry, I missed that the PSUs were internal to the units. I do agree. 
However -- take a look at the app notes on my website about finding and 
killing RX noise. It's likely that serious ferrite chokes wound on both 
power leads and any other wires coming out of the units would knock that 
noise down a lot.
