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
http://www.dellroy.com/W4EF's-Ham-Radio-Page/Portable_Operation/EU2000i_Filter.htm
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
correct
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.
