Make sure you pay attention to any sound system you may have hooked up to
it. I was causing RFI to my wife's Imac with 100 W with the antennas about
40-50 ft away from it. No RFI at all on my Dell machine right next to the
rig and 10 ft from the antennas. Spent considerable time with ferrites, but
got it quiet now. It's been quite awhile, but as I recall the biggest
contributor was the external speakers and sub-woofer she had attached. They
were routing RF back into the computer. Make sure you filter those kinds of
leads as well as the keyboard, modems, etc. K9YC's site is the place to
look for "how to" info.
Bottom line here was that the Imac was more susceptible than any Windows box
I've had, but still could be quieted down. Too bad, as otherwise it is a
very nice computer.
