It is almost always a bad idea to try to re-engineer a product, 
especially one that is badly designed, as this one clearly is. NK7Z and 
W0LEV have the right ideas.

The only thing I would do other than what they suggest is to break the 
AC feed to it and add a well-designed common mode choke. The 2-stage 
choke that W6GJB and I designed for use on Honda generators would be a 
great option. See page 23 of http://k9yc.com/RFI-Ham.pdf  for details.
