P3 Noise signature

I usually check into the No Cal Net on 3533 each night. I've begun to
get predictable noise with a unique signature on the P3 WF. It's a
series of bands, the first [around 3545] is the widest, they get
narrower up from that and the separation seems to be about 40 KHz. The
higher components get narrower but aren't any weaker.

Occasionally I've see it come on to an otherwise quiet band, and all the
"bands" on the WF drift some before stabilizing.

I have a screen shot from the P3 I'll send, anyone have any idea what
this is? I never see it in the daytime on any band, just in the
evening, which is suspicious ... plasma TV?

If it's my neighbor Casey, I'll just need to live with it, we don't do
battle with our neighbors. Besides, Sampson, their cat, gets along with
ours and shares his food.

In reply to this post by k6dgw

Fred,

I have a plasma tv here and that sounds close to what I see when it is
on. It pretty much wipes out the AM BC band and very ugly for all ham
bands 160-10m. I can take a snapshot with my P3 and send it to you if
you'd like to compare.

Ironically, I just had a daytime RFI issue resolved here. It started a
few months ago. I would come home from work in the morning and listen
around for awhile and notice the noise would start when the sun came up.
Eventually, I noticed it went away at night. It was prominent on 160-20m
and it was only detectable on my vertical dipole. I could not hear it on
my doublet about 60' away. It was like very rapid lightning type pulse
noise. I was starting to think one of my neighbors may have installed a
new solar panel array.

Long story short, I finally eliminated power sources in the house
without relief. I then realized that the vertical dipole was near a
garden with some 2-3 year old solar lights my wife put in there.
Removing the lights and batteries eliminated the noise. A couple of the
fixtures had water in them and my guess is they were the problem. Crazy
to think a little solar charger like that could raise so much hell ;-)

Re: P3 Noise signature

RFI...

I have a very pronounced noise on my K3 (and, my Icom Pro III too) on the 80 meter band and it has peaks about 20KHz apart. Very broad (P3 wave form about 6000 Hz wide and it has slightly bell-shape) and very distinctive in the noise sound you hear on SSB audio.

I know the source though -- it is my wife on the treadmill. You can almost see and hear the motors and treadmill belt moving by the subtle pulsating of this RFI on the K3 and P3. It is strong too -- peaks at about 40/9. And, as an experiment, I got into my truck with my mobile rig (Icom 706) and drove off. I was a quarter of a mile away by the time the signal strength dropped to a level that I could not hear it anymore. So, if this is the kind of thing bothering you it does not need to be close.

The good news is that we both prefer going to LA|Fitness rather than work out in our little home gym so this is no longer a big issue but it still happens maybe a few times a month when my wife chooses to work out here. But, usually that is when I am at work or not on 80 meters which is almost always at night.

Re: P3 Noise signature

Interesting. I have an older treadmill here (15 years+) but have not
seen that type of RFI. The bad news is that it needs to be replaced and
I'll probably have this issue with a new one.

Good news is though that I can't work out and operate at the same time.
And the tv is usually not on if I'm in the shack unless the wife is home
at the same time. Usually not very often though.

Amazing the sources of RFI these days. I'm still hanging on to most of
my 15+ year old appliances just to stay away from newer RFI generators.
But like you said, they can radiate over some long distances so I'm sure
I'll hear my neighbors stuff like Fred.

Looks like I might have to pour over Jim, K9YC's RFI doc again ;-)

Hi Fred,

If you grab some screen shots of what you're seeing using the P3
Utility, it may give some of us some ideas about possible sources.

Our noise generating treadmill is a NordikTrack APEX6100xi model. I think it is at least 10 to 12 years old.

Re: P3 Noise signature

Dave,

You may be able to knock this noise source down with effective line
filtering. The first thing to try is winding many turns of the AC cable
around a #31 ferrite core. It won't help noise that is radiated
directly by wiring inside the unit, but it can take the AC cable out of
the picture. And you should also approach the manufacturer and firmly
insist that they fix it.

Re: P3 Noise signature

In reply to this post by Dave Van Wallaghen

I don't know if RFI is inversely related to price or not but my Precor unit is RFI free. If I were to go shopping for a new one I would take my K3 along and see what happens when the proposed new treadmill is running.

This approach is much harder for TV because there are always so many on at the same time at the store. Wish there was a registry of makes and models of any kind of appliance listing whether they caused RFI or not. We hear occasional anecdotal reports but these are nowhere collected.

Thanks Jim - I should try it. I have never tried to curb it mainly
because it is usually off when I'm in the shack. This is a 10 year old
Panasonic set and I seem to remember reading on the RFI list a few years
ago about a couple of guys trying to work on their sets. As I remember,
they said the set (screen) radiated most of the RFI and that putting
toroids on the AC line did not help.

But you can never have enough #31's around so it won't hurt to try it
here! It is getting pretty close to replacement time for this thing
anyway. A much lighter (and a little bigger) LCD is in the future ;-)

Thanks again & 73,

Re: P3 Noise signature

In reply to this post by k6dgw

If it's not found to be a TV monitor with an approximate 40 kHz
horizontal sweep rate, then the next most likely will be a switching
power supply that runs at 40 kHz, rich in harmonics. I'd look for LED
lighting that comes on in the evening, like under-cabinet kitchen
lighting, or low-voltage yard lights. I had a couple of light sensor
sockets in my front and back porch lights that were radiating when the
lights came on automatically in the evening. Also found an automatic
coffee maker making a racket, and a switching power supply in a laser
printer.

You may be able to isolate it to something in your house by turning off
circuit breakers in your electrical panel one at a time (or if you like
to split the dictionary faster, do one-half at a time, and then cut that
in half again, and again). Once you know the circuit, then you can
start unplugging or turning things off or on. Having a handheld radio
that picks up the noise will be helpful.

Hope that helps,

-- Dave, N8SBE

Hope this works, it does for me but that usually means nothing.

Re: P3 Noise signature

I had problems with non-moving patterns that resembled yours. When you
tune the VFO, do the peaks move - or are they static and do not move
when the VFO moves?

If they do not move, replace the BNC patch cable between the P3 and the K3.

I had patterns showing on 75 meters during the day when there should be
nothing. When I replaced the cable with one of my own craftsmanship -
the problems went away. Now the P3 works fine.

No. I had that problem, very narrow signals that moved as I tuned,
couldn't get to them. Fixed with a new cable from, who else? Elecraft.

This isn't there during the day, except sometimes on weekends. When it
comes, it's like a switch. It happens when I'm the only one home and I
haven't turned on our Panasonic LCD TV. It's now 1930 local and it has
either gone away, or moved somewhere else. It does move, slowly.
