Hello Everybody, I am thinking about purchasing a pure sine wave inverter. Does any body know of who manufactures a quality unit that is quiet EMI/RFI wise? I am thinking of 1000W - 3000W range. Thank You and 73's Cedric WA2FTV |

I am curious if you got any answers to your question abouit a low RFI inverter? I have had RFI problems with a Samlux 3000 watt inverter which i purchased because it was supposedly low RFI. But is generates a lot of spurious radiation at least on 160 and 80 meters. Not so bad on 40 meters and above. |

For a year I've been trying to reduce the 10 dB over S9 hash from my champion 3400 watt inverter. FINALLY I succeeded -- using a $128 filter from england, and then TWO common mode chokes FT-240-43 with about 9 turns of a short 16gauge walmart extension sorce. Will be publishing it in the nfl qst newsletter end of the month. Standaard stuff....finally worked --- wiped it clean off the S meter. Became inaudible on 40 meters. Then tested my friends 2kw cosco AI power inerter generator -- it was maybe 6 db quieter than mine. That is the news so far. |

The below link is the most recent testing that I have seen for a while. https://www.ar15.com/forums/outdoors/Generator-and-Inverter-power-comparison-with-oscilloscope-pics-/18-695204/#top |
