These inverters are NOT quiet.  Slide 213 in this pdf shows what I had 
to do to kill the trash coming out of their SMALLEST one to use it to 
power the logging computer for HF mobile contesting!

  My partner in these events, W6GJB, bought one or two sizes up; it was 
MUCH worse, and there was nothing we could do to make it usable.

FCC Part 15 Class B is still a very loose RFI spec, and the specified 
testing setups fail to reveal the design and construction errors that 
can cause massive radiated trash.
