RE: Carbon Fiber Tubes for Diamond Dust???
The only DD I had interference issues wtih was my first one which I built from the kit with FG tubes, but that had to do with the interior setup of the antenna that is shown in the kit. It may have been just to close to something I'm not really sure because ever since I started routing my antenna out the wing tip and have never had an issue since and I use CF tubes on everything and good old 72MHZ.
