Our club (NCCC) has done several group purchases of this generator, and 
we've had very good experience with them. It will run a 100W rig AND a 
600W power amp on CW or SSB in economode (we use K3 and KPA500)! At 
home, I use to to power the critical circuits in my home during power 
failures, and I also use econmode. Those circuits include a refrigerator.

But it IS necessary to choke the output to kill hash on the higher HF 
bands. Easy to do -- 4-5 turns of the output cable through the big 1-in 
i.d. #31 Fair-Rite clamp-on, or a stack of four 1.4-in i.d. toroids. 
Line filters do nothing. Photo on slide #7 of this Power Point.
