There were plans in past issues of Monitoring Times and QST for a
homebrew version of the ANC-4.

I've got that article stashed someplace, didn't look real complicated. I
think Far Circuits ( /www.farcircuits.net/ ) has the circuit boards for the
project and they will also supply a copy of the article for an extra buck or
two. RM~

BTW- You can elliminate one of the control pots' in the design if you
wind the associated coil with a bifilar winding.

"mystery" static in my area.... S-9 worth of noise!

What do you (not) know about this noise?

Not sure where its coming from. It ususally starts late morning and
lasts up to midnight, its very much on time every day.

Before you get into noise cancellers, go for a walk around the
neighborhood with a portable radio to locate the noise source. Maybe you
can eliminate it so you won't need the canceller.

It wouldn't necessarily surprise me if your source of
noise is the same as mine: a television set. In my case,
it's our main television set, an 8 year old 25" RCA that
I pick up noise from with my outside antenna whenever it's
turned on.

The worst noise source I had was a VCR. It was producing noise all over
the shortwave bands even in standby mode.
It took me a while to find it out.....

Luckily our VCR or our other audio/video equipment
don't radiate anything, but then again, it's bad
enough with just the television.

In our case, the best thing to do is to turn it off. If
the guy's got a neighbor that simply lives with the
televison on most of the day, he might be out of luck
with a regular antenna.
