All of the radio users suffering from PLT are behind you on that one!!!
Open the windows
With windows opened and pointing in a different direction the focus effect goes away. Bit too simple I guess?!
The units have been corrected after I emailed Bill to raise the issue. It would appear the original source material from Ofcom did not clearly state the units either; but then they think PLT does not pollute the radio spectrum, so what do you expect?!
Missed a trick
Central Bedfordshire [unitary authority] are swapping old concrete-posted low-pressure Sodium street lamps for LED units on steel poles. They are nice and bright and so far I have not detected any QRM from them. However, the designers have missed a trick. The inclusion of a PIR sensor to only power the light when needed would save on the electricity bill and the un-welcome light pollution. But that would be too easy! And the old-folk would complain!!
Perhaps if Cable Modems had come with Firewalls from day one, cable companies would not be playing host to some of the largest spam bot-nets?! This initiative, whilst welcome from the rest of the Net users, is about 10 years late!
When is a transmitter not a transmitter?
Ofcom have declared that PLT is not a radio and thus does not fall under the Wireless Telegraphy Act. It falls under EMC regulations and BIS/Ofcom have not been prepared to act/rule on it in case the EU comes at them with a big stick for hindering "free trade". They do not seem to have the balls to go back to the EU and declare PLT illegal as it fails EN55022; but then we have learned EN55022 is not legally binding, although the 'Essential Requirements' are, so EN55022 should be by definition.
Prosecution would be nice, but the courts would never be able to handle the case load. It is far simpler for the gov. to publicly announce the issues via the media and give people 28 days to comply. Suppliers, such as BT Vision, would also have to pull their finger out and remedy the problem they have largely created!
The 1980s CB problems could come back as those of us who are being wiped out by PLT and ignored by Ofcom feel we have no choice but to boost our transmission power. We know it's illegal and it will just add to the general noise and crud which is affected HF radio use, but when the government authorities charged with keeping the spectrum clean refuse do to anything, what choices do you have?
It would appear that one could import any old radio, use it on any old frequency allocation, and get away with it because it's CE marked. That seems to be the case with PLT!
Broadband over Powerline is dead!
BPL installations are either dead or dying. They cannot provide the bandwidth compared to ADSL/SDSL/Cable and they radiate crap all over the HF radio spectrum rending Amateur Radio, Citizen Band and Shortwave listening (SWL) useless. Those of us who have a legitimate and legal right to use the airwaves are ensuring the nail is firmly hammered in the coffin that is BPL/PLT/PLA!
Don't hold out - demand fibre to the home! If the salesperson says they can't do it, tell them to clear off and not to come back until they can. It's called "market demand"!
BBC claim 2015 switch-off
The BBC are already claiming a 2015 switch off: http://news.bbc.co.uk/1/hi/entertainment/8592664.stm
Do they know something we don't?
And what of the new Digital Radio Mondial? You won't be able to receive it until Ofcom clears up the PLT mess. Oh, and you might not be able to pick up DAB soon as Belkin have launched a 1Gbps PLT device which wipes out everything to 300MHz!
Air heaters run through the engines
The air-supply for the cabin is heated via the engines. If a crack occurs in the heat exchangers, the smell of kerosene comes in to the cabin.
Whatever happened to DRM?
It is being trailed, but if you live near someone using PLT devices, you can forget about it! The conducted emissions from PLT wipe out the very transmitter frequencies used by DRM.
What sort of meters?
Electricity meters, Gas meters, light meters? The public needs to know!
Set Phasers to Smurf
They've all turned Blue captain!
They want to fine the UK for snooping, yet they are allowing and encouraging "Power Line Technology" (and I put that in quotes as it's not a technology) and the accompanying destruction of the HF part of the radio spectrum.
Double standards. Fail!
The article was not on BT Vision boxes, but BT knowingly supplying Comtrend PLAs which have failed every EMC test going. It does not matter if you purchase UPA or HPA devices, they all fail BS EN:55022:1998 and spew crap all over the HF radio spectrum.
Everyone from Radio Amateurs to CB users to the military and aviation are suffering from the interference caused by PLA devices and Ofcom's stance sends a clear message to all radio operators - do what you like, we don't care! So I'm sure you'll be saying "haa-haa" when a local CB user running 500 Watts of illegal power causes all of the electronics in your house to go nuts!
Do yourselves a favour - fit UTP wiring and a Gigabit switch. It will be less hassle, less power and you'll not incur the ire of the HF radio users!
No point in buying them!
They will be banned when Ofcom are replaced by a regulator prepared to enforce EMC law.
I have been using CB radio since the late 80s as a one to one and one to many communications system. I am 37. Am I a pensioner?
We used to play a game called 'Foxhunting' where a car would hide and the 'hunters' would track them down on their CB signal. It made for some entertaining evenings with many local home-base users listening in to the madness. You cannot do that on a telephone!
The point of Amateur Radio is to spread knowledge and training in electronics and the Electro-Magnetic spectrum. It is about transmitting with the least amount of power to see how far you can get. It is about listening to the natural EM sounds of the planet and the universe and working with them.
If you have no interest in this, then please quietly sit in the corner. We may have no interest in your stamp collecting, but we are willing to leave you be.
Ofcom are not fit for purpose!
The QUANGO Ofcom are lying and ignoring the tsunami of evidence against PLT technology coming from sources around the world. This technology does not just affect a few radio amateurs, it also wipes out the entire CEPT and UK CB radio bands and makes it impossible to listen to weak short-wave stations.
I have reported 28 interference sources of PLT QRM in the Biggleswade, Bedforshire area which affect mine and my friends home-base systems and our ability to use our CBs when mobile. Ofcom's stance is a mobile unit can move away; not when the entire town is blanketed with noise you cannot! 4 Watts of transmitter power used to run for miles. With PLT, it runs for metres and we are looking at the need to run illegal power amplifiers to reach over the noise. This will in turn cause much wider interference to totally innocent people. Two wrongs cannot make a right, but if Ofcom will not enforce EMC laws, why should we care?!
Despite being issued with a case number, I am still waiting for any kind of resolution. One address has been taken "off-air" but another claimed by Ofcom to be solved is still radiating crap all over the radio spectrum. Want to see the extent of the problem in small market town?

I really do not see why people feel the need to use such a poor "technology". Cat 6 is cheaper to install, does not cost anything to run and does not spew crap all over the radio spectrum.
Fibre to the home
You can free up all of the broadcast spectrum if you get your finger out and fibre up the houses! Radio stations can be re-broadcast via Wi-Fi and everyone can Cat 5/6/7/8 wire their houses to connect everything up.
Wiping out the HF band
Power line Ethernet adapters are wiping out the HF band causing problems for radio amateurs and CB users. These devices can radiate via the house wiring and wipe out HF reception for up to 500m. They are not subject to the Wireless Telegraphy act and seem to be pushed past correct EMC testing. HF band users want this poor technology banned!
Don't be a problem - install Cat 5 in to your house!

The BBC iPlayer is the only one to work under Firefox running on Linux. The offerings from the others require IE. A single system which supported all platforms and allowed you to view the content of the main UK channels would have been highly beneficial to all of us; hence why we can't have it!
And they wonder why people record TV onto their computer and share it via Bittorrent?!
ODF all round then!
That should avoid any future cock-ups!
I had the radio advert "Autoglass repair, Autoglass replace." in my head reading Joe's post. Now that would make for a funny phone-call:
"Hi, I've got a crack in my windscreen."
"What hit it sir?"
"A loose toolbag!".
"What is the vehicle make and model?"
"BOEING Space Shuttle."
"Does it have Blue tint or Bronze tint?"
<Sound of laughter at 42 miles up!>
They always forget CB and Amateur
In 28 days, the "hereos" walk past a truck on a bridge in London and ignore it in favour of a taxi. Chances are it had lots of diesel and a CB. I would have driven that to Dover and called across the channel for help. But I'm an Engineer and cannot watch disaster shows: They simply assume those left have no Engineering or medical skills and I would find that hard to believe!
Long range Radar
The Radar system at RAF Fylingdales has a power of 2.5MW and can see 3000+ miles.
Hope the US system has a cloaking device!
It strikes me as odd...
...that we have planes that can take off, fly and land themselves with minimal input from the pilot (granted, they cost a lot more); yet something as simple as a train cannot be accurately located on the track or controlled via computer?! Really, why are drivers needed? It cannot be that complicated to automate the whole process.
@ Matt Sidall - Yes there are systems that are supposed to stop trains from passing stop signals, but it depends on the rolling stock, what country has legislated for their use and the train operators.
This could all be for nought!
They cannot fly if the clouds are too low - especially as the commercial flight paths will have to be cleared. We've missed the fast-jets (Red Arrows, Tornado or Typhoon) displaying over Shuttleworth (and the surrounding area) in Bedfordshire for a number of "summers" due to lousy weather.
Does this mean the cows around the LHC will start spinning around when it reaches full power?
Can farmers now herd cattle with large electro-magnets situated around their fields?
Actually, the harvester cost £400k. The GPS guidance computer would have been a few thousand, but paltry compared to the price of the power-plant and control systems for the rest of the harvester.
With the accuracy now available, I'm sure it will not be too many growing seasons before we see the harvesters off on their own with the farmer sitting in his Land Rover keeping an eye via laptop. How's that for remote control toys?!
What time is it on the Internet?
Wouldn't it have been funny...
...if their [RSAs] domain registrar also used the securesite.co.uk and couldn't verify their credit card payment?!
This law came into effect...
because some random bloke in amongst the 60mil+ that inhabit this country viewed extreme porn, got off on it and killed a teacher (another random person from the 60mil+). Her mother has campaigned, much as Sara Payne has been trying to out all peados with her "Sarah's Law", for a law against extreme porn.
This law, as far as I can see things, is another example of the politicos (and this applies to local gov. as well) listening to the minority instead of telling them to bugger off! There should be minimum trigger levels before knee-jerk laws are allowed to disrupt everyone's lives!
The rivers still run into the sea!
No one seems to be prepared to use the potential energy of the rivers any more. There is one mill left in Bedfordshire: Jordan's mill on the river Ivel just south of Biggleswade still uses the river to power its grinders.
On the river Great Ouse, just north of the village of Willington, there is a 25 foot drop in the water level. There is nothing but a lock and an over-sluice. A 25-foot head of water could produce energy 24x7; if someone was prepared to invest in river generation!
It'll never work!
It will only take one person to work out how to send mal-formed junk to the database and we'll all do it. As it will be contracted out to the highest bidder, they will settle on an M$ solution, so it should be quite easy to blow up!
Put it to a Reg reader vote!
The correct English spelling of 'Gaol' or the Americanizm of 'Jail'?
They should be forced to liquidate...
...and return the money to the tax payer.
Gaol time in the Tower of London if they don't.
(For the American audience, Gaol is the correct spelling of Jail. Just so you know!)
What about people that just stop?
I've come across a number of old-ladies who just stop in the road to take their call. No indicators, no hazard flashers and the engine is still running. Last time I checked, the engine running on the public highway means you are driving the car; therefore, you are still foul of the law. Are there traffic cars dealing with these idiots? No!
In Bedfordshire we now only have two traffic cars with four fully trained drivers. They spend their time patrolling the M1. There's is nothing on the A1 near where I live, save for the locals* from Biggleswade Police in their diesel Astra's. We used to fear being pulled over by the "County Sheriff". Not any more: We can lose the Astra's quite easily (see comment below).
(* When I say locals, I mean police from anywhere but the local area. Without GPS and the helicopter, they are completely lost and are unable to follow someone who knows where the farm tracks run!)
Funny how we didn't seem to need all these terror plods when the IRA were in full swing! What are the gov. afraid of? The general public realising the whole thing is a sham, and the real terrorists are actually "middle-England's" NIMBYs and fascist parents demanding everyone be tagged, tracked, and profiled whilst the scary outside is littered with speed-bumps and bubble-wrapped lamp-posts.
Answers on a post-card...
I wonder if I can obtain a copyright on my fingerprints, then charge any agency a "license" fee when they want to use them for ID?
I feel we should in-undate the Patent Office now. 60m people copyrighting their prints should keep them busy for a while!
Yes, this is a big deal!
When the root zone for .com was enhanced (buggered), all .com spam checking suddenly failed as all domains resolved. When I say all, I mean anything with a .com - even if it did not exist. The spammers thought all their Christmases had come at once!
Any DNS look-up that resolves a non-existent domain with a "help page" will again screw with (part of the) spam checking, unless you can run your own DNS server.
No issue with traffic running your own caching DNS. Traffic is only generated when you create a fresh look-up or a cached look-up TTL has expired. Once a look-up is cached the server responds within 1 millisecond.
And it is more than a nice idea: The DNS system where I work uses the exact same system (as I implemented it!). We are not reliant on the up-stream DNS servers, so we do not care if they are "broken".
Time to learn Linux...
...and run your own DNS server caching from the 13 root servers. You are safe from this kind of nonsense - unless Verizon mess with the root records again!
