Broadband is a *disaster*- anyone else? what to do?

[Guest guest]

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 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?

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,

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.

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,

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,

Dear Marc, , 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 : )

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.
