Yeah, I sure do. I bought a Honda Eu1000i this past February after having major 
RFI problems with a Mitsubishi 600/900w inverter-generator and have been having 
all sorts of the same RFI problems with the Honda. It simply is not 
well-filtered, if filtered at all.  I built the line filter (common choke) as 
described by 
 and STILL had major RFI problems. Long story short, I ordered both the new 
MFJ-1164 line filter and the W4RRY battery booster and, after considerable 
delay due to MFJ manufacturing backorders, UPS, and USPS, only just got them in 
today, so they're untested. Until now, I've been just using my battery banks to 
operate and keeping the Honda turned off until I needed to charge the battery 
banks. If these new toys don't solve the problem, I've bookmarked several 
toroid and bead suppliers (particularly 
http://www.palomar-engineers.com/RFI_Kit/rfi_kit.html ) to go to Stage Four of 
 ive measures. Beyond this, I don't know what I'll do except go back to my huge 
and consumptive Coleman 3750 generator for ham radio operations; it does NOT 
create RFI.
