OT P3 video of RFI, ideas?

This is a bit off topic but perhaps other P3 users on this reflector have encountered this RFI and have some idea where it comes from and perhaps a remedy? There must be a couple of thousand P3 users on this reflector.
The below is a recording and includes sound of this nasty bit of pulsating RF.

Video recording:

http://www.flickr.com/photos/ak5x/9214448105/

It is not always there. When it is there in the 20-meter band there are siblings almost as strong at the following frequencies:

13.975

14.032-the recording

14.126

14.220

14.282

14.469

In addition, there are less strong signals that follow the pulsation; one is visible on the recording at 14000 (far left on the P3). They are also in the 17 meter band. They are not in the 15 meter band or above.

I have pulled the big switch and it is still there on battery power. My suspension is a neighbor with plasma television. Is this what plasma TV looks like? It is directional in nature and the strongest signal comes from a 40-degree heading, roughly Europe from my location, or to a cluster of homes to my northeast.

Re: OT P3 video of RFI, ideas?

Bill,

We have a &*^%$$ Samsung 63" plasma TV in the family room. When it is turned on, that's exactly what it looks like on my P3. When I'm on the air and someone turns on that piece of crap, I know in an instant.

Re: OT P3 video of RFI, ideas?

I thought plasma TVs were outlawed some time ago. Obviously there are
still plenty of them around. I see occasional interferers but at a
lower amplitude - must be neighbors' TVs.

I'm wondering if this is a serious comment? Go to any Best Buy, and
you'll find they are far from illegal.

Re: OT P3 video of RFI, ideas?

In reply to this post by Rick Tavan N6XI

Rick -

I put a couple big clamp-on's on the power cord. No help. The only other cable going to that TV is a heavily shielded HDMI cable from the Denon A/V unit. From what I understand, the RFI is generated in the plasma cell area, and not on any cables. I may be mistaken, but I believe the best way to suppress plasma TV generated RFI is with a 12-gauge shotgun. And, believe me, if (1) it was legal, and (2) not so expensive - I'do just that to ours!!! :-) :-) And, no - don't do that to your neighbor's TV!!!!!!

Actually, that Samsung TV gets little use these days. Our main TV is a 65" Panasonic Viera plasma set that surprisingly generates no RFI crud.

Re: OT P3 video of RFI, ideas?

In reply to this post by Matt Zilmer

The plasmas were not really 'outlawed' - but California made sales there a problem because they are rather inefficient users of electrical power. (As in close to a KW to create a picture on early models.) - That said, their picture is usually vastly superior to the LCD sets, even those with LED backlights.

Re: OT P3 video of RFI, ideas?

In reply to this post by Bill Hammond

Bill,
I have a 50 inch Panasonic plasma and when it is on, lower bands 40 meters
and below are near useless.
It causes some problems for me on 20 meters and up but it gets less as the
bands go up.
My P3 display is similar to yours.
Otherwise it’s a great TV, great picture.
I have tried several things but only thing that has helped, especially on 20
meters and above is to move ham antenna further away from my house. As best
I can tell RFI comes from the screen and not the cables or the power cable.
If anyone finds a better solution, other than shotgun or not using it,
please let me know. 73 good luck

Re: OT P3 video of RFI, ideas?

In reply to this post by WM3M

In the UK there has been a great deal of interference caused by plasma screens. The QRM is radiated by the screen and gets worse with age as the power to the backlight increases to compensate for reducing emissivity. Recently Panasonic, the main culprit, have been replacing plasmas with their latest LCD model that have much better pictures and no rfi. Current LCD models now have much improved performance and have better pictures that the plasmas that are now being phased out.

A campaign has been waged by concerned amateurs and details can be found at http://www.ukqrm.org.uk/

Best of luck

Contact Panasonic and remind them that the TV was certified as Part
15 compliant, and that if they cannot fix it you will contact the FCC
and report their failure to maintain part 15 compliance.

That's about the only thing you can do unless it is new and is still
under the 30 day return limit.

Plasma TV's and their manufacturers are evil.

Bill
It took me a year to locate the noise source similar to yours. It is
worse on 80m and the frequency shifts as picture content changes. It
turned out to be next door. They had bought a 60" Samsung plasma. I took
a portable AM receiver over there, turned on their tv and it totally
blanked out the entire HF spectrum.
No amount of line cord filtering, torroids etc. does any good
whatsoever. The QRM radiates off the face of the plasma screen and can't
be tamed. The only cure is a new LCD tv!
My neighbor has not been helpful. They refuse to let a "serviceman" sent
by Samsung to look at it. I gave up 2 years ago and have managed to make
some antenna changes that help a little.

That is a plasma TV near your home.

How do I know? My next door neighbor has one. He just moved in last
month and this week the noise started.

What can you do about it?

I went next door and asked him if he had a plasma TV and he answered
"Yes, but I don't watch it except on Saturdays when my girl friend is
here."

I brought him to the shack and showed him the noise on my P3 SVGA
interface, them we went to his home and turned it off, after which we
returned to the shack and I showed him the signal was gone.

He now has a borrowed copy of the ARRL RFI Book and an explanation
from me of how to contact the Mfgr and ask them to fix it. I know
they can't, so I then told him to contact the FCC and report an FCC
Part 15 violation and give the name of the Mfgr (SamSung) when they
tell him sorry they can't fix it.

He was very nice about the whole thing and we now observes quiet time
except on Saturday night when I'm usually not on the air.

Fortunately he has a very large LED TV in the Den which makes no
noise.

Re: OT P3 video of RFI, ideas?

Suppose the manufacturer can't or won't fix it? What happens then? I have a Pioneer Elite plasma in my house that radiates plenty. Anyone have any experience with Pioneer?

Re: OT P3 video of RFI, ideas?

Although this thread is quite mature, I will add my experience with
plasma TVs, one of which is a Pioneer Elite. Both of my next door
neighbors have plasmas - one a Panasonic and the other the Pioneer.
DXing "used to be" my favorite aspect of ham radio, and 40m my favorite
band, but since the neighbors' acquisition of the plasma TVs, the plasma
noise/spurs can be a constant S8 to S9. To say it's frustrating,
especially when I've always tried to be a "good neighbor" in terms of my
ham radio operations, is an understatement. Plasma TVs are equivalent
to thousands of spark gap transmitters!

Until recently, I only operated either very late at night or early AM,
or when the neighbors weren't home, or if by chance, weren't watching
TV. However, a few months ago I purchased a Pixel Technologies
RF-Pro-1B magnetic receiving loop which has helped immensely. The
plasma noise is now typically an S4 or S5, sometimes even a bit lower
when I carefully adjust the azimuth of the the loop with the rotor.
It's also helped with the persistent line noise problem that the power
utility is totally unresponsive to address. I essentially use the
receive antenna input on my rigs 100% of the time now.

I wish the FCC would ban the sales and marketing of plasma TVs!

Re: OT P3 video of RFI, ideas?

I have a neighbor who has a plasma. But what is worse I have a neighbor two doors down whose outside lights cause 30-40 db of noise from 7MHz to 20 MHz! I offered to change them for him, and asked him to at least just turn them on at night. He has a timer, but he leaves them on many times all day. His wife was great, if they were on I'd ring the bell and ask her to turn them off...no problem. The one time he answered the door, he started yelling at me calling every name under the sun, and called the cops. Cops looked at my station (one was a cb-er) and said there was not much they could do.I solved the issue by buying an active antenna and a ncc antenna phaser. Here is what it can do!

Copy the link and paste it in windows media player (File - Open network location).

Problem solved. Too bad it doesn't work remotely.

Re: OT P3 video of RFI, ideas?

Remeber the report in QST about the person who had a well pump
interfering with a ham's operation - After several notices indicating
that he must turn it off or change it, the FCC issued a very heavy
forfeiture.
Perhaps complaints of RFI to the FCC can do some good (but it will take
time).

Hi
I am using a dxengineering active receive antenna with a 102" whip, mounted at ground level about 30 feet away from my av620 vertical. I'm using is as a noise antenna while the av620 is my main antenna.
Waiting until the weather cools off to install my first beam. Should be less noisy than the vertical.
