Fiber optic broadband putting final nails in cb/hf radio in ireland

    Since fiber optic broadband has been installed in cavan there is severe noise across all hf frequencies, 20 over 9, sounds very harsh throughout the town even mobile, like frying eggs (radiation in the air?)
    Anyone else with this issue yet?

    I don't think a bit of qrm in Cavan is going to mean the end of hf in Ireland. Do you work for the Irish independent?

    A lot of it could be down to the use of power line adaptors. Eir and the likes are installing these everywhere to save them drilling holes and spending time on proper installs. They kill HF locally.

    exactly its powerline adapters, i have a set in my house i used to run a cctv camera until i got around to hardwiring it, it caused noise in spot parts across hf and wipes out 4m on me, they are however the new improved version i tried the old ones before and they wiped out hf altogether for me

    The first of the consumer 'PLA' were junk alright, spewing their RFI guts everywhere. America was plagued with power companies sending Internet over their over-head power lines which had a massive effect to HF.

    I guess by now consumer PLAs are a little bit quieter but we're still to the detriment of the switch-mode PSU which has to have its' 'say' on the airwaves.

    Expensive to buy but still cheap quality with designers cutting corners to satisfy the accountants.

    If people complain to Comreg , radio interference will be investigated. I'd imagine the more people complain the more they might do to ensure compliance.

    Comreg? Really? :)

    No ? who then ?

    I'm just amazed that people have faith in Comreg to solve such problems. They should have been dealing with this from the start if it was a spectrum management issue.

    Agreed. Unless those devices caused persistent and catastrophic interference to emergency/air traffic comms, commercial comms or local television/radio/telephone services, Comreg would have zero interest, and I mean zero interest. Hobby HF and radio experimenters are bottom of the pile with regard to Comreg resources.

    That's because there's not enough people to complain and those in the hobby probably don't complain enough.

    Are you joking?
    Comreg have all the deterrent effect of an ice cube in the Sahara.

    I have dreadful RFI that wipes out the MW and most of the SW bands Usually most of the day and into about 1 am then crystal clear probably as neighbours turn off appliances, lights etc.

    Thinking the Magnetic loop is the best way to go in urban environments today. They certainly get great reviews.

    I'm moving to the sticks soon, so will probably hold off spending money on loops and experiment with a long wire antenna's first.

    I'm dying to get a decent setup for my SDRPlay.

    Sometimes it's just as bad in the sticks. There's noisy power comes on the lines, put there by neighbours' appliances, but fortunately it diminishes with distance. It's not bad, most of the time, but some nights it's dreadful.
    I've been over everything of mine and the place is now a forest of ferrites and chokes, which has made a tremendous difference, and for the past decade I've been leary of cheapenese power supplies, regarding them with real suspicion until they prove themselves to be quiet.
    I don't have data over power lines in the house, but I'm sure my neighbours have, and more than one of them have noisy thermostats that make their presence known in the chilly weather.
    Some oddities, like crappy video senders on cheap baby alarms, can black out the HF bands for a kilometre around.

    Have you tried a magnetic loop ? supposed to give fantastic results.

    These get great results but they're expensive.

    I'm hoping a cheap long wire antenna will work when I move.

    When I take my Tecsun pl-660 and PL310-ET out in the sticks the difference is amazing.

    After my re-awakening in radio, I have plans for better antennas than I had before, so hope to sidestep most of the issues by getting in strong signals and keeping them clean, and giving the weak ones a fighting chance of being heard.
    A magnetic loop will be tried, and one or two of its bigger brothers, space / time / can-be-arsedness permitting.
    The great thing about antennas, is you can make some crackers for very little money.
