Actually, I probably shouldn't have responded to a 2008 post at all. :-) I had
moved all of my RFI@contesting.com email to an archive folder and accidentally
left 4 of them behind. When I went back to look at the reflector folder, seeing
4 posts, I just assumed they were new and responded. Hey, if it's the worst
mistake I make this year, I can live with it.
The device does seem to still be available, so I will order one anyway, so this
mistake actually may do some good.
I can offer a few points that are worth mentioning.
First, this forum is an excellent tool for those who want information about
RFI, and to discuss it with others. Although ARRL has an RFI section in its
forums, I don't expect that it will ever replace this reflector. In fact, the
ARRL web pages will continue to point to this list first as the best source of
discussion about RFI.
ARRL staff do read a lot of the posts here, although when my life gets busy, as
does Mike Gruber's, W1MG, we may be more lurkers than posters. I'm trying to
change that, because although there are some top-notch folks here, Mike and I
may be unique in the absolute breadth of our contact and involvement with
nearly all aspects of RFI that may affect Amateur Radio. That breadth,
combined with the experience and depth of knowledge of a group of people that
offer ARRL staff excellent advice on RFI matters, can and will make a
difference nationally and internationally with respect to some of the RFI
problems we all face.
I mention this not for a pat on the back, as we get to do this work as paid
staff, so there is nothing special about us -- just the amount of time we can
devote to Amateur Radio RFI issues. I also offer this to make what I think is
an important point -- although Mike and I do spend time here, please don't
assume that if you post it here, we have seen it. In cases such as devices
that appear to be operating way above the FCC limits, especially intentional
emitters like this video camera, ARRL can move fairly quickly to buy and test a
device and either persuade the seller to stop selling it, or to file a formal
complaint with the FCC. But we can only do that for devices we know about, and
there are LOT more eyes on this list than the 4 eyes that work in the ARRL Lab,
so please do involve the Lab staff and report these problems. I am always
running across old posts about things we could have helped with, had we only
known. Use the address rfi@arrl.org to contact Mike and me an
d we will do what we can to help with RFI problems.
In cases that involve actual interference to hams from consumer devices, the
ARRL Lab has a cooperative agreement with the FCC that can, when the time is
right, facilitate getting FCC involvement in an RFI case, in a way that allows
them to send advisory letters to those generating noise, based on a good report
and well-documented attempts to fix the problems.

This one is pretty good too...look at the bottom of the page.
