The inverter in question was taken OFF LINE. That is, it was turned off and the supply lines FROM it to the breaker panel that was installed for it, were disconnected as well. These were extension cords. At this time, the noise COMPLETELY disapeared. When the unit was switched back ON, the noise was STILL gone, but when anything was plugged into it, an extension cord, the supply lines to the breaker panel or a volt meter, the unit begins to radiate. Anything plugged in becomes an antenna, radiating the RFI being produced. I sent AIMS an email about this particular case last Sunday. They have not felt the need to respond to me. This is ok because a higher authority may just be contacting them. It appears that this dilema is befalling a number of the amatuer radio operators around the country. All one has to do is to read PART 15 of the FCC Rules to understand how copable the USERS of these devices are. Yes, it's the USERS of the equipment, which are responsible for their use, in your homes, wherever. The manufacturers at this point may not have to answer for it just yet, but when you guys buy them and their useage begins to drive people around you crazy, the end result is that you'll just be sending them back to whatever manufacturer is peddling these things. I'd like to think that someone has built a better mousetrap, an inverter that works in harmony rather than to create chaos. So far NOT so good. So is it the BRAND of inverter or just what? You guys may have the answer.
