I will work on the power line filtering. Thanks for the advice.
There is light at the end of the tunnel! Today, I did some experiments.
I was able to reduce the interference by adding another toroid with lots
of turns to the satellite feed. I only have mix 43 toroids right now, but
it seemed to help. I have some mix 77's on order. At this point it looks
like all of the interference coming down the satellite feed may be gone.
I am still getting some (although not as much, esp. on 40 meters) with
the satellite feed disconnected and playing a DVD. I'll start working on
filtering the AC line again. Maybe I just need lots of turns and mix 77.
I hope so. Thanks for all of the advice. I'll keep working on it.
