Hi sorry if you got this twice. I originally posted this to emr-emf which
you may also get. Hi All and Happy Holidays. We recently got broadband internet and phone (through cable, not DSL), and what a *disaster*. Had to get rid of the phone part immediately, because it made me so agitated and I absolutely could not sleep. I am not talking about using the phone; if the cable was connected (the same cable connected computer and phone) I could not be in the house. So, we cancelled the phone part and now the cable only connects the TV (we have always had that with no problem) and the computer. Now, I can be in the house as long as I am two rooms or more away from the cable computer modem or line. If we unplug the part of the cable that is nw only going to the computer, the problem goes away. My husband is very disappointed. He loves the speed of the cable internet (6 kb per minute or something like that). I am writing you on dial-up Aol, with the cable internet unconnected. Otherwise, I really can't use the computer without very bad symptoms. Anyone else have this problem? I was hoping to go to law school, but now that I see that I can't tolerate cable broadband even less that I can tolerate dial-up, I am very discouraged. Do you guys think I might have better luck with just DSL, that uses phone lines but is faster than regular dial-up? Stetzerizers plugged in all over the place. Maybe I need more? As I said, husband really loves faster broadband and more than that really does need it for his job. Any ideas greatly appreciated. Thanks very much.

I have often wondered if my broadband digital TV, digital cable,
digitial phone (all over cable) causes problems, but I haven't been able to think of any particular reason how it could, so haven't taken the time to disconnect it and see if it helps. In my case, that would mean we lose phone service also. Coaxial cables are "supposed" to be quite shielded and the signal levels are very very low even if they are leaky, but I've heard others say they have reaction to sattelite dishes and feeds, which have similar properties and extremely low signal levels. If indeed we react to cable telephone service and cable internet service, then it seems that something must be going on well outside the realm of just signal strength and frequency. Something very odd indeed. The signals from cable or sattelite won't even come close to the strength of signals in the air like tv transmitters and cell phones, and in fact are undetectable by measuring equipment unless the equipment is attached to the cable. If they bother people (and it seems they do some people) it begs the question of what is going on? I'm curious if Vinny or Charles have any experience here. The one thing in common to satellites and cable internet/phone is the sheer quantity of information that is being carried. I have no knowledge of a physical principle where people would be sensitive to that, however, so at this point I don't understand how people would be sensitive to it. That doesn't mean it isn't happening. Maybe someone knows something more about this aspect and can comment further. Is this possibly related to the quantum noise phenomenon that I don't yet understand? Garth On Dec 2, 2006, at 11:57 AM, [hidden email] wrote: > Hi All and Happy Holidays.

Hi Garth:
Well, two things come to mind here regarding CATV and broadband cable: Most coax cables (except for solid metal outer sheath cables, which I have used sometimes in designing systems for weak-signal reception work at UHF frequencies, and which cost about ten dollars per foot!) do allow a small amount of RF EMF field to escape, but the amount of escaped EMF energy is incredibly miniscule, usually from 52 to 90 dB below the already-low signal level on the CATV cable. Also, however, a type of "common-mode" stray RF singal can sometimes travel along the outer sheath of coaxial cables; this signal may have little or no relationship to the actual desired signal traveling inside the cable, and may instead have been created by ground loops or by stray signal pickup and/or resonance. Usually, grounding a coax cable really well to a really good ground (a really good ground at RF frequencies will almost always involve more than one ground rod and perhaps other ground means as well) at one end, or placing one of those hinged-type ferrite sleeves over the outer shell of the cable at one end, will eliminate much of the strength of these stray fields. Lastly, and this is where things get a bit esoteric, but we ARE getting to the fringes of Western science here at times: some coaxial cables, along with some types/designs of capacitors, seem to be very good at acting as transducers/radiating antennas for converting a bit of the desired fields/energies in them into what some folks call noisy "scalar fields" and what others (such as Glen Rein) tend to call noisy "quantum waves", and what I tend to call noisy "sub-quantum fields", and thus may emit way more of such noisy subquantum fields than would otherwise be expected for a given signal level. with care, --Vinny At 09:52 PM 12/2/2006, you wrote: >I have often wondered if my broadband digital TV, digital cable, >digitial phone (all over cable) causes problems, but I haven't been >able to think of any particular reason how it could, so haven't taken >the time to disconnect it and see if it helps.

Hello,
I have found in some houses, that the cables for television (analogue cable TV) are transmitting VLF frequencies, so around 30 kHz, which may give electrosensibles trouble. Here, perhaps an extra shielding with aluminium foil along the cable may help. It may also be possible, that those cables contain *stray voltages* (50 Hz and 380 mA) because of faulty installations somewhere at the source. Recently, I encountered an Xbox 360, which was transmitting enormously. Directly on the box. Farther away, it was less.

Hi folks:
A minor errata in my earlier note below about coaxial cable. I believe that due to the very late hour of night at which the missive was penned, I may have accidentally used the wrong term for the signals which can travel down the outside of the coaxial cable outer shield (versus inside the cable, where we desire them to be), when I called the undesired signal a type of "common mode" signal. I am still hunting for just the right term for the signal traveling on the outside of the coax cable, but "common mode" just does not feel right. What I was really describing is where the outside coaxial shield of the cable is accidentally acting in itself as a kinda single-wire transmission line, and thus radiating some signal, or even where it is acting as a part of an accidental antenna system, as can happen in some ham radio and CB transmitting antenna systems and even occasionally (and hopefully briefly) at some commercial AM, FM and TV transmitting sites on the coax cable traveling from the transmitter to the antenna where there is a tremendous impedance mismatch between the impedance of the signal in the feedline and the impedance of the antenna, causing a high voltage standing wave ratio (VSWR), and this can cause high amplitude out-of-phase signals to travel on the outside of the coax cable, radiating as well into space. However, this scenario does not seem to happen often with consumer-signal distribution coaxial cables used for CATV and for broadband/CATV cable, as the power levels are rather low and the equipment made and marketed for these markets usually employs rather good impedance matching and also employs pretty good shielding of signal-processing stages, largely for reasons of economy, efficiency, and to avoid running afoul of the FCC and irate customers experiencing interference to other devices. BTW, if and when your coax cable IS acting significantly as an "antenna radiator" due either to high VSWR or to unintentional resonances or poor grounding techniques, it is usually rather easy to detect: any fairly-sensitive EMF detector device, if its probe is brought to within a distance of anywhere from one-half inch to two feet from the coax cable outer shield, will register a significant and noticeable increase in EMF field readings or in RF E-field readings (and somewhat less-often in RF magnetic field readings. If the leakage energy is over the level of a few watts, it will also light a small flourescent bulb held by one end in one hand if the far end is placed near the "leaky" coax cable. with care, --Vinny At 12:14 AM 12/3/2006, you wrote: >Hi Garth: > >Well, two things come to mind here regarding CATV and broadband >cable: Most coax cables (except for solid metal outer sheath cables, >which I have used sometimes in designing systems for weak-signal >reception work at UHF frequencies, and which cost about ten dollars >per foot!) do allow a small amount of RF EMF field to escape, but the >amount of escaped EMF energy is incredibly miniscule, usually from 52 >to 90 dB below the already-low signal level on the CATV cable.

Hi folks:
And, one more note about the whole CATV coax cable thing... A few years ago, when DSL (i.e., over phone lines) was not yet available in my area due to the fact that I live in the mountains in the wilderness, I made the mistake of trying cable Internet access for a while, not that I am saying that there is inherently anything wrong with cable Internet access, but my only provider happened to be Adelphia, and it was at the height (or low) of the time when their corporate funds were being systematically looted by the Rigas family, along with totally incompetent local franchise administrators. In any case, I briefly ordered cable service turned on to my home, so that I could have cable Internet access with Adelphia. While I never had any problems with ES/EHS response on my part to the cable service being activated, I did have a myriad of problems with my PC as soon as their board was installed. I was eventually able to trace the problem to the fact that there was a 30-volt AC potential between the outer shell of the Adelphia coax cable and the utility AC ground wire at my home, causing noticeable sparking. And, when I hooked that cable shield to the input of an oscilloscope/spectrum analyzer, it was loaded with non-cable-type signals up through about the 2 MHz range, although the only significant power levels were present at the 60 Hz power line frequency and at its 120 and 180 Hz harmonics. I decided that the problems were due to very poor system grounding techniques on the part of both my local utility company (I had already complained to them a year earlier about poor grounding in my area causing lightning strikes on power lines to seek ground through the admittedly excellent ground installed on my poultry electric fence system) and on the part of Adelphia cable. As a remediative measure, I then bonded their ground at the home entry point to the utility system ground, and I then added several ground rods (with appropriate bare copper conductors and clamps for hookup) to the utility ground system near where it entered my home, and this cleared up all of the stray-AC-voltages-on-cable-shield problems instantly. with care, --Vinny At 05:42 AM 12/3/2006, you wrote: >Hi folks: > >A minor errata in my earlier note below about coaxial cable.

Hi folks:
Final note on the coax cable topic. I have just completed a web search and discovered that the term "common mode currents" is indeed a term which is still in vogue in RF engineering circles for the radiating coax shield phenomena which I was trying to describe... And, as mentioned earlier, a good chunk of (well-chosen) ferrite core/bead placed around the outer diameter of the coax will usually attenuate the signals at about 200 KHz and up (usually well into the GHz range), but will often do little for the lower-frequency common mode signals unless you use really massive chunks of a ferrite such as type W. . . with care, --Vinny At 05:42 AM 12/3/2006, you wrote: >Hi folks: > >A minor errata in my earlier note below about coaxial cable.

Dear Marc, Charles, Vinny and Garth,
Thanks very much for all of your feedback about Cable broadband . My husband and I are sorting through all the information and suggestions. For right now, when he is not using the broadband, I completely unscrew the cable. That takes away the agitation. So far, I have tried wrapping the T-shaped place where the computer line screws into the cable with aluminium foil as one of you guys suggested and it does help somewhat (I don't understand why this does this help. I would think it would have to be a mu metal), but to really end the agitation , I have to unscrew it. Also, my husband moved the cable modem to a computer on the first floor of our townhouse and this also helps (if I am on second floor), so when plugged in the cable is running around the ceiling and down the stairs to the downstairs laptop (yes, I know, he's a good guy : ) So, either the cable is leaking or the modem is putting off some intolerable signal. I cannot even sit near the computer when it is plugged into the cable broadband. As mentioned, I am only using dial-up, it's bad enough. I'm sure just about anyone I would tell about this would think I'm nuts. I wish I *was* making this up! Anyway, thanks again so much to all of you and sorry I take so long to respond. I only go on the computer once or twice a week. Happy Holidays and Best to All of you : ) Stephanie [Non-text portions of this message have been removed] |

> completely unscrew the cable. That takes away the agitation. I'm not sure what is being unscrewed from what! Do you mean the coax cable is unscrewed from the cable modem? Do you also need to turn off the cable modem to get relief, or can you keep it turned on? I suppose you could try using an alternate brand of cable modem, and see if that makes a difference. What brand/model number are you using now? (maybe looking at the specs will tell us something) Also, we have someone here who gets relief by placing a battery next to the offending equipment. Maybe you should try that and see if it makes any difference? She uses the larger sized batteries (C,D) for this. Marc (who has never noticed anything from his DSL modem) |
