Yep... I do notice a difference when I put a little attenuation on the line. Most of my pixellation comes on 801 (Local Fox) and 803 (Local CW). Without attenuation, they are usually bearable, but occasionally completely unwatchable. With 8dB attenuation, they are always watchable, with only occasional mild pixellation.... but 802 (ABC) will sometimes lose it's signal completely. In the last couple days (while trying to test), I've actually not seen very much pixellation at all, and currently don't have any attenuators on. Go figure... as soon as I want to test a theory (moca interference), it gets better on its own. I'm sure it's just a temporary clear area and pixellation will return eventually.
