Regarding the RFI problem when running 100W. I also had a bad RFI problem when running 100W. It would get into the computer, TV and all the audio equipment in the house.
What I finally did to cure the problem was I ran 3/4 inch flexible copper water pipe from the shack out 20 ft to the yard, where I laid down a 50 ft length of 3ft wide galvanized fence. The 3/4 inch soft copper flexible pipe provides a large surface area for the RF. Then every 10 ft along the length of the fence I drove in a 3 ft copper ground pipe and soldered it directly to the fence. So I have 5 ground rods at different points along the fence as it lays on the ground. Next spring the grass will grow over it and hide what I have done. Then in the basement ham shack I used a copper ground buss behind the equipment and ran 3/4 copper braid to all equipment including the computer. This took me about a weeks worth or hard work. Now I run 200 Watts without any RFI at all on any band. If I run a full legal limit 1.5kw there are a couple of bands where I get into the audio of the HiFI set. And that can be solved with some RFI filtering on audio amp and speakers when I get around to it. Its a real treat to run the ham rig without having anyone in the family getting upset :-) -- frank W7is ------------------------------------------------- This mail sent through IMP: http://horde.org/imp/ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
