If the computer is a ATX variety, remember the power supply does NOT sleep
when the system is off! rather the motherboard does...pull the AC cord off
the back of ALL computing equipment and then check for noise. Also check all
"Compact Flouresent" fixtures as these damn buggers ARE noisy. Last but not
least.....lamp dimmers, even if the lamp is OFF!!! yep, noisy even when the
lamp is dark. Some are actually quieter when the lamp is on full
bright!...Happy hunting......Eddie

I have narrowed down interference to definitely being a computer. I turned
off everything electronic in the house, and still get a lot of
intereference. I am guessing it is coming by way of the power lines into
the
house. I even disconnected the antenna and was using only the coax
connecting the antenna to the receiver, and still got interference. It
does
not happen only on one frequency but all up and down the bands, becoming
more noticeable at 13 Mhz through about 15 Mhz regions.

So, I am wondering, which would likely be the most plausible source:

Television cable
Wireless network
Home computer network through house wiring

The next door neighbors do not have a computer. They recently bought a
combination telephone-alarm clock-radio (am/fm) device, but doubt that is
the source. There are other apartments near me.

Would a filter help - low pass or high pass ? I looked at MFJ, but they
want
$100 a piece for what they offer.

THANKS
