HARMFUL INTERFERENCE TO AIR TRAFFIC CONTROL FREQUENCY FROM POWER LINE NETWORKING

[freddo27]

Mike, the PLAs aren't even in his street or any neighbouring ones so it's safe to assume they're going up quite some way. A friend of mine in a nearby village was getting endstop signals from a powerline adapter over half a mile away. It took Ofcom half a day to find it. The danger is in the cumulative effect of several, or even several hundred or thousand PLAs in one area. This could render ground to air comms unusable over populated areas and far beyond. That's what the CAA fear.

@freddo27 Very interesting. I thought they worked up to a person's main breaker then it was only resonating around the house's internal wiring. It it is travelling yards or miles away, then that is a concern. I can see us having a problem getting these things banned, as most people think it is a god given right to have broadband and computers any way they can, as opposed to ham radio, which is not even known to many people. Worrying times it seems. 73 Mike M0SAZ

I agree that PLT devices are a nuisance, but surely they are not being used in an Airport/Air Traffic Control Centre - the interference is localised to a few metres of the PLT itself. Apart from inconvenience to amateur listeners, how will they affect the communications between aircraft and the ground? Mike M0SAZ

@a120068020 I just read the text accompanying this video and I can't believe anything resembling a PLT device can emit noise over several streets. If it is proven to be the case, we are all in trouble. Not trying to be controversial it just seems incredible. I wonder if it is some other digital source of emission, that sounds PLT ito listen to?

@a120068020 A few metres, if only that were the case. The household mains radiates the RF from these things like a good long wire and I speak as someone who's had 4 doses of the damned things in 2 years. This is a Comtrend pair, the Ofcom engineer even knows the type. He's failed to locate it yet because it's re-radiating from the 3-phase overhead lines. Sadly, RF doesn't know when to stop travelling. I hope you don't end up with any of these near you, but unless we act, we all will.

Do we have to wait for a major problem caused by people

who put money before life of people.....Act now and close

It seems that OFCOM is doing very little to combat the use of this spectrum polluting kit, if there is an emergancy I wonder what OFCOM would have to say then?

In the interest of national security these things aught be outlawed or at least require a licence like any other device that transmits, I still cannot figure out why you Brits still have to pay a TV licence, as here in the colonies that sort of TAX was scrapped many years ago.

@beachsandinspector Thanks for the comments,

In spite of PLT being just convenient gadgets and not enabling technology,they seem to be determined to push it upon us, I suppose we'll find out what the agenda was and whose fault it was, when we bolt the proverbial door long after the horse has bolted.

Well, with the licence fee we do get ad-free programming from the BBC. The over 70s (75s?) get a free TV licence too, although how long it is before the axe falls upon that is anyone's guess.

How can they let this stuff be sold? I've got someone locally with some PLT devices and shortwave might as well not exist with all the interference :-/

Amazing! I wonder what other services will be affected in their vital communications.

This is a disgrace and very dangerous to life and limb
