After shutting off all the various circuits in my home, I discovered that the
noise is actually coming from the TV in our living room.
The existing dimmer switches are made by Lutron, and are not making much noise
after all.
Whenever I plug something into one of the TV's inputs (cable, composi
This little unit might be of interest to anyone trying to track down rfi around

Zac,
The dimmer switches can be 'fixed' - remove them, place on a solid
surface and swing at them full force with a hammer :-) . Replacement
with regular light switches will cure their noise. If the CF advocates
have their way, you will have to get rid of them anyway, the CF lamps

Yes. Remember that the test procedure is to unplug the device
or turn the circuit breaker off. Modern
They probably aren't really off. You might wanr to take this to RFI
list (contesting.com), but some report particular brands of Lutron
dimmers are quiet(er). You might be able to justify (to a landlord or
other financial approver) replacing them on an energy basis.

After looking into this further - the noise is still there even with the dimmer
switches turned off (circuit is on). Is this normal?

After shutting off the circuits in my house, it appears that most of the noise
is coming from two dimmer switches and a switching power supply.
The dimmer switches are for lighting and I'm not sure what the power supply is
for. It's plugged into an outlet in my closet and is screwed to the wall.
Hey Zac,
That sounds very similar to what my plasma TV emits. I have my window line
running along the outside wall where the TV is mounted and when it is on, I
can hear it very plainly. The tone fluctuates with changes with the picture.
I've also noticed that it peaks at certain frequencies as wel

Zac,
I have no idea what could be causing that noise, but it certainly sounds
like it is frequency dependent (you were tuning during the recording
were you not?) and from the intensity, I would judge it to be a local
source.
The KNB2 will not likely reduce it at all, but the KDSP2 has a chan
