Just to say that switch mode supplies CAN be made to be as RF quiet as any 
linear supply.  Trust me, back in the 80s and early 90s, I worked for a company 
that made (among other items) power supplies, both linear and switch mode.  
Some of the units were totally RF quiet - I know, I was the poor guy who had to 
go out to the lab to do the conducted (aka out the wires) and radiated 
emissions and susceptibility testing, and some of them were REAL quiet (amazing 
what the military can demand and get when they don't want people to be able to 
track the supply by RFI)
