Why do you think that's a radio problem? :-)




When I turn the computer off, the radio station noise drops
dramatically. It doesn't matter if I use AC or DC. I can detect the
large noise change in my car from the garage.




That sounds like a computer problem, not a radio problem.
What am I missing?


Probably nothing. However, I'd be willing to bet that I wouldn't have
this problem if I were 100 miles closer to the radio station.


Absolutely. If the station signal is relatively stronger than the
computer noise, the computer's RFI will not be so much an issue. Right
now, they are about the same strength. Moving the computer will probably
help a lot.

Just out of curiosity, what is the frequency of the station you are
trying to recieve?

And while we are at it, is the noise on the radio in just one spot,
or is it on pretty much the whole band?

810 AM, KGO. Good question about the width of noise. Let me check ...
I just took the radio out near the PC, and operated it on battery.

With the PC on, and moving in steps of 10KH from 700 to 900:
noise almost everywhere execpt at 830, which is about 3 miles from my house
and over a hill.

With the PC off, some noise everywhere, but 710 (station and somewhat
noisyg), 740 (station and somewhat noisy but not bad-- KCBS inSF, CA), 810
(clean), 840 (station and somewhat noisy). In other words things improved
quite a bit.
