You are right to be VERY concerned -- variable speed motor controllers 
of all sorts are notoriously bad sources of RF trash. BUT -- the best 
place for questions of this sort is the RFI reflector, which, as I 
recall, is accessed via contesting.com.  When you're there to sign up, 
search the archives.  We've recently discussed exactly this matter, and 
there have been several more over the past few years.
