My previous house was in one of those subdivisions where you can lean out the window and touch the house next door with your fingertips. Presently, I have 2.75 acres, with horses next door (perhaps I should have PMA check their teeth to see if they're radiating something), deer, raccoons (one of my all-time favorite animals--both beautiful and intelligent), opossums, foxes, and all sorts of things down at/in the pond.
I expect I've got about five more years, max, before a wave of development crests and breaks over our neighborhood. The grocery store I mentioned above has been there only a year. And no fewer than five fast food joints have sprung up like mushrooms on cow pies. Two drug stores, a gas station, and a dozen other stores and offices. Three schools. Worse yet, they're widening the roads.
I smell trouble brewing.

Well let's see. According to ANSI T1.523-2001, Telecom Glossary, "spurious noise" is defined as:
Circuit noise or interference that is like a signal. [T1.401-1988]
That seems to pretty well define that big 16kHz spike in your measurements.
What exactly is your definition of "spurious noise"?

To show that I am not without a sense of humour, I'll give you Fizzard's and some other folk's answer: Spurious noise = KBK's contributions to this thread.
The harmonics fall on the line, students. All 3 graphical examples fall right on top of each other as well. It is really obvious, then. Of course, you have to have access to the link that DIMITRI originally made and CHARLES HANSEN provided. You have to register with the website, and if they approve you, (and they have previously rejected several posting here), then you can read all 150+ pages of assorted stuff, including the cable measurement topic on pp. 130-139. It is up to DIMITRI to release this stuff for general dispersal. I give permission for this. You hear me Dimitri! I request the release of this info. It does neither you, nor me, any good with it locked up the way it is. Nobody paid for that privilege, so it should be OK. Thank you Dimitri for doing such a nice presentation.

Do you have a point here? I can't quite figure out what it's in response to.

john curl said:
I don't have access on diyHifi. But if p. 132-134 are your original distortion plots, then I'd already overlaid them years ago.
Again, what's your point?

john curl said:
So are you saying that p.132-134 are not your measurements of the JPS, Radio Shack and van den Hul cables?

I have no special access. Only approved people are allowed. I do not even know who to contact.
john curl said:
Ok. I've come to find that p.132-134 are as I suspected. Your three distortion plots of the JPS, Radio Shack and van den Hul cables.
And as I said, I'd already overlaid these images some four years ago.
Here they are.
So once again, what's your point, John?
An externally hosted image should be here but it was not working when we last tested it.
Mike I checked the link, it works for me. Perhaps you too are not allowed on that website. Please don't blame me, but you can share your problem with SE.

I'm sure I haven't done something that needed to be done. Actually I'm too tired to care, it was a joke. No blame intended.
I am told that there is an alternate url that MIGHT work for some of you. What I printed before works for me.
