    Call me naive here... but nobody has questioned the "valid audio broadcast in a spectrum is fine, while noise/interference in that same spectrum is automatically evil radiation with negative health connotations" position?

    If you are gonna worry about radiowaves, shouldn't you be worried about anything in that spectrum whether it's a valid signal or not?

    Original thread from OP:
    (Radiation in the air??)FIber optic not meant to interfere with anything, why is noise level off the scale since install, worried about radiation coming from these lines and possible hidden health risks.

    We've figured out it's now physical fiber cable wrapped around the esb lines. This sort of cable doesn't have any RF energy associated with it as it only carries light. So we can put that to bed now. The noise source is not coming from fiber cables. If he lives in an estate in town do we actually have any power lines above ground? I thought all power lines ran underground in estates?

    Yes, it may be coming from a faulty transformer? and then down a power line. In which case he can track it down...

    Anyway, OP, it's easy to track down the source of RFI, if it is coming from power lines or any other source.
    You say you have a portable AM receiver? Then you can use this to track down the source.
    There are lots of places on google to help you track down the source of RFI.

    Please do not blame fiber optic cabling however as this carries no RF source of energy.

    I didn't even want to go down this route, as clearly the OP is a CB enthusiast. His main concern is the static/noise being caused to his radio.

    I am in country and there is no fibre to my door .
    I had man from eircom come to my door and tell me i have access to 1000mb speed?? They told me it is in my electric, I just need adapter to decode, fibre In towns and through powerlines in country. Money saving, sounds like bpl to me that was abandoned because of severe interfence and health hazards related to radiation coming of powerlines.we want fast broadband without the serious health implications.

    OP says .....
    Not sure, there is about 150 houses in this estate (big estate) noise is very bad all over so can't tell them to switch of equipment, at least 70 have this broadband.

    so it would appear he lives in a town. Also I doubt the ESB has rolled out any sort of fiber network to the countryside or area that's not a town yet.

    I'm not contradicting the OP. The OP is contradicting the OP.

    Tell me about it.....

    I'd love to help OP but can't get any information out of him in order to do so.
    I think i'll give up on said OP

    About 1 miles from town ,fiber is running across powerlines out to my estate, and yes the interference is very severe in cavan town and surrounding areas since this install and constant,I am not asking is it Fiber optic broadband causing this, I already know for a fact it is! The question is what can be done about this and how can this be resolved.??

    Fibre optic cables do not cause RF interference.

    Light is a source of energy and electrical light in this sense, also on every third or fourth pole there is a transformer boosting the signal of the broadband, very big possibility this is what is generating the very harsh noise , if you say it's not possible well I give up.

    Any chance you would read all of my previous questions and answer everything? I cannot help you as you keep failing to answer the questions put to you. I need more information and for you to work with me on this... it's not my job to drive to cavan to tell you where the noise is coming from... it's yours... if you can answer my questions I can steer you into the right direction.
    Cheers.

    Contact COMREG or the ESB and see what they say.Posting here about it constantly is not going to help you.

    i'll have to google WUM but yeah, i'm wasting a bit of time here...
    Ah, I've had my fair share of RFI, but god damn it i'd be able to provide a bit more detail.

    Wind Up Merchant. This is not his first posting on the supposed issue. He has been told all this before yet returns weeks later spouting the same nonsense.

    Fiber goes to electronic box then fiber to home, noise is same all over, my video on YouTube, search (cb radio noise after fibre optics install in cavan )

    OK... so now I get another piece of information.
    There are electronic boxes...

    Come on OP....

    I viewed your video. How am I supposed to say what a high noise floor is being caused by? this video shows nothing except a high noise floor on 27Mhz!

    Look... grab your portable radio, remove the antenna from it and go walkabout near one of those electronic boxes.
    Maybe a video and pictures of this along with hi-resolution images of the electronic boxes would be a good place to start?

    Find the source of your RFI... it's not being caused by fiber cable itself. It may well be caused by an electronic box if there are lots of them on poles distributing the fiber to multiple houses.

    Are you driving around while listening to the interference?
    Is so, you must rule out interference caused by the car or power supply on the radio.

    Is the interference on all bands or just the CB band?

    I watched and listened to the OP's video and that fire crackling noise is what I had before using a long-wire for shortwave used outdoors only. I do remember it was happening some days and not on others for me and I thought it was coming from a neighbours house, I'll try a few things to see if I can find out what exactly is the cause of that crackling noise.

    Now I understand what you mean with this particular noise. It is not fibre that is causing it and that is for sure, more likely a transformer of some kind. Has the council recently put up new lighting poles on the street close to you ? just wondering. Check all of the below. Use a small pocket transistor am radio tuned to 650khz with the volume up and move to the nearest street light and see if you get that crackling noise, but try your whole abode first as listed below.

    very first thing for OP to do is put his Yaesu radio onto a car battery or similar and turn off his houses power at the mains.... see if the noise is still present.... then start the portable AM receiver work...

    I done a few tests myself to recreate that crackling noise so I re-connected my old long-wire antenna, and then I received this noise on 6.00mhz to 27mhz and higher. I had the receiver on battery power and turned off the main house power switch and could still get the clicking/crackling noise.

    I used a battery powered shortwave radio and an AM radio to track the noise down but couldn't find where this particular noise is coming from, it's actually everywhere. I walked to the back of my garden and it was still there, and walked down the street and still there. This one is a tricky one to track down, so I can see what the OP is talking about.

    It could be from a neighbours house, but if it was then the crackling should have dissipated the further I moved away from it, it actually seems to be in the air. Whatever it is it is powerful over a distance. It has me stumped. I never hear this noise though because I use a loop antenna that blocks most noise out. It's very annoying either way listening to that noise.

    I have to track this down, as it's a head-scratcher now. And it's not coming from the street lights either.

    Isn't that the whole point of threads like this, to help find the problem and then move on. I never thought trying to track down a nose annoyance for radio amateurs was nonsense.

    The op is a crackpot. This thread was never about solving a problem but just his vendetta against FTTH and the horrible cancer it will cause. Look at his previous threads/posts in the broadband forum.

    Not once did he mention amateur radio so now he has found something that he thinks can back up his allegations.

    Ah man, this thread has it all!

    Radiation in the air! It can even travel through space!
    CB radio!
    Cavan!

    All the hot topics of the day.

    Well blow me away lol, bloody space-cakes everywhere, and me walking around trying to track that particular noise down, well, I'm going to teach myself a lesson for being an asshole :mad: :D

    I'm not looking forward to the next trap I fall into.

    Seeing that I started I said I may as well finish. I tracked down that crackling noise that seemed to be everywhere, and it is from the electric gas boiler of neighbours on the street. No wonder it was everywhere as the cold evenings came in it appeared a lot. Anyway, good luck folks.

    OMG, the electric/broadband people have kidnapped Bongalongherb and are using his a/c
    "no no everything is fine, it's not us no no, we're lovely, we wouldn't irradiate you, it's those Gas people"

    The OP has gone missing too :eek:
