Has to be the Office of Fapping - Offap
And do it now!!!
My current 'leccy provider has an app. They helpfully send me a reminder email once a month and I womble outside with my tablet to read the meter. Total effort required: 30 seconds. So I still fail to see why I need a "smart meter" - especially when I am running dumb appliances that are over 20 years old. Is everyone going to rush out and replace their fridge, freezer, water heating system, et al? No, of course not. Time to scrap this silly idea and get on with new nuclear build-out!
PLT is junk electronics that should never made it on to the market. It wastes power and helpfully obliterates the radio spectrum up to and beyond 300MHz. See: http://ban-plt.org.uk/ and http://www.ukqrm.org.uk/ on the mess these devices and other junk electronics create.
I used to enjoy DAB for Planet Rock. Then the rot, facilitated by Ofcom, started. The bit rates started to fall because "it doesn't sound any different", then to cram more "choice" onto the D1 mux, most of the stations switched to glorious mono. The justification? Most people only buy radios with one speaker. Seriously? You are going to ignore those of us with 2 or even 5.1 speaker systems?! If DAB is aimed at replacing Band II VHF, it is a spectacular failure!
Streaming has become the fall-back at home, but it's far from perfect. The streams for Planet Rock and Absolute 80s can be extremely flaky at times - even on a 40/10Mbps VDSL circuit. I will be forced to put a Freesat system up if I want better playback.
Ironically, my ancient Yaesu FT-757GX amateur radio transceiver can produce better quality sound than DAB - even when tuned to short-wave radio stations broadcasting from China!
In the BBC's coverage of this story, the DECC claimed smart meters would tell the consumer how much energy their appliances were using. I know how much the 3kW heater is using. 3kW. And when it's been running for a hour, it has used 3kWh. I do not need a fecking smart meter to tell me that! I do not need a smart meter to tell me how much power the fridge and freezer are using. I know, and I don't give a crap! Get on with building new nuclear and stop this nonsense!!
There is still no definition of how this "smart" crap will communicate with said appliances. They can feck off if they think they are using PLT! As soon as Ofcom have the nuts to publish their SI amendment to the Wireless Telegraphy Act, every radio user in the country will be going after PLT, Plasma TVs, and SMPSUs!
...that the cellcos will roll-out their kit in areas where they can make the most return and continue to ignore the rural areas. Those rich-picking areas are usually well served by DTT and have high-speed Internet access available, making 800MHz Internet access completely pointless - at least for the home-user on cable or VDSL.
I remember watching CNN - I was enjoying the fireworks displays whilst I was "on standby" for my company in case the Y2k bug bit. At one point in the evening, but not midnight here in the UK yet, they thought they had a major scoop. They had tracked down an American aircraft carrier in the Pacific and were on the phone to the captain. They wanted to know if they had experienced any issues as they were past the International Date Line, and so their clocks and systems might be showing the bugs. The captain promptly informed her that all vessels at sea synchronise their clocks to Greenwich Mean Time. I laughed so hard, I fell of the sofa! The lesson here: do your research!!
There was, of course, a bug that bit. The sister site to the one I looked after thought it would be best to power down their AS/400 system - in case it went screwy. The IT Manager on my site asked if we should power our kit down. "Hell no!", was my response. Coming from an Electronic Engineering background, I knew what was coming. The sister site returned to work in January and flipped the switch to power-up their AS/400. BANG! The capacitors in the power supply promptly exploded and they were out of action for 3 days. Oh how I laughed!!!
...but it is too beholden to the whims of big-business to add such a law to the statute books.
And only using mobiles is not the answer. I have a new mobile for work and the number is only known to staff, yet many of us have been receiving PPI calls from a Manchester company. They are either using auto-dialer tech to see whose phone they can hit, or EE are selling the numbers!
The Bedford number has also tried calling me. I am a mere 12 miles from Bedford. I might become annoyed enough to track them down...
Many a Saturday night was spent in the 90s 'fox-hunting' on CB in my local area. If you are transmitting, you can be found - even if you are mobile. Something the script-kiddies over at Anon seem to have missed. Their text talks about transmitting anywhere [on the radio spectrum] - more so in countries with repressive regimes. They have overlooked the fact that the military have radio kit that covers everywhere. You start putting out signals in a country that is typically radio-quiet, and you might as well shoot yourself!
Something else I noticed in the text: They used the correct English spelling for "neighbour", yet bashed the FCC. Too chicken to take on Ofcom?!
I have to agree. I only have a few titles on SACD, but I am not about to throw the player away in favour of BluRay and DRM locked content - especially when I cannot extract a PCM copy for my iTunes library and hard-drive based iPod. You can shove your MP3 versions where the sun does not shine! I will stick with CD and SACD as both can be played in any CD player.
Shows like "Two Pints of Lager and a Packet of Crisps" started their tenure on BBC2 before being shoved to the new shiny BBC3. As already said, why not push the content for BBC3 and BBC4 back to BBC1 and BBC2. Most of the shows that are shiny and new on 3 and 4 end up repeated on 1 and 2 anyway. Cut out the endless repeats and show the new content on 1 and 2 at sensible times; then leave the endless re-runs to Dave, Drama, Yesterday, and Really (have I missed any?).
Of course, the question is then what to do with the dead air-time on the multiplexes. BBC3 and 4 take over when CBBC and CBeebies go off air. Are they to go 24-hour, or be scrapped as well?
Ofcom are judge, jury, and gaoler for many aspects of policy in the UK. They are only too keen to cry that the EU told them to do something (PLT), but drag their feet over other EU recommendations (SSB on CB), whilst ignoring laws on statute (EMC). Scrapping them and splitting off their functions to other bodies should be a priority for the government!
I am surprised there are not more cases of this going on in schools. Whilst they [schools] continue to employ a gaggle of low-paid, under-qualified people, or farm it out to the cheapest contract, this sort of thing is always a risk. It really is not that hard to implement vlans, locked MAC address DHCP, and smart-card login - with auditing against the smart card for recording of grades. Of course, that would also require decent ICT* training for the teachers, as I can wager with considerable certainty, that none of them have been exposed to corporate-level IT controls. The kids in this case should be rewarded for demonstrating such glaring short-falls in their [former] school's security procedures.
* Note to schools: No-one in the IT industry calls it that!
"DCMS, the National Audit Office, and the Parliamentary Ombudsman all declined to get involved."
In battling another failure of a QUANGO, no-one has the mettle to tackle Ofcom, bring them to heal, and actually force them to do their job correctly. I thought President Cameron said we the people were in charge?! If that is the case, who does Ofcom, OfGem, OfWat, and all the other useless "Office of ..." answer to?
"After switchover, the DTV signal doesn't broadcast across The Wash" - yes it does. My mother lives in Dersingham, and I pointed the main high-gain aerial at Belmont - which is straight across The Wash - and it works just fine. They are lucky in that part of North Norfolk as local TV (BBC1 East and ITV Anglia) is provided by the Sandringham transmitter. Got to keep the royals sweet!
Many of the reasons for only moving to Windows 7 are coming from the big software houses. I have worked with architect and theatre design companies who have only recently started to kill off the last of their XP machines. They are only moving to 7 as software houses, like AutoDesk, have said they have no immediate plans to support 8 (although that may have changed...), and many of these companies have a large install-base of CAD-type applications, so they want compatibility and support. Having now standardised on one version, and remembering the hassle of an XP/7 mix, they are not interested in a 7/8 mix and all the problems with a touchy interface.
Yes, they will be scrap, unless 'Pure' (and other manufacturers of other brands) offer replacement boards for the insides of the radios. If the government does move to DAB+, all of the older DAB-only radios will become WEEE junk as many have their functions embedded in silicon. A chip change will be required for them to work with DAB+; and that's not in the manufacturer's interest when they can force you to spend another ~£100 on the "latest and greatest". That will put people off, with many just giving up on broadcast radio!
Perhaps the drop in listener numbers is down to the farce that is Digital One. Dropping my favourite radio stations, Planet Rock and Absolute Radio 80s, to MONO and a stupidly low bit-rate has resulted in me ripping my digital radio out of my Hi-Fi stack. I have no interest in listening to the BBC, so for me, DAB is dead. And that is quite annoying and costly. I was a fan - although not of the bubbling or crap MP2 codec. I have a self-fitted DAB unit in the car that will be removed soon, plus a number of "collectors edition" 'Marshall - Planet Rock' branded DAB radios that are technically scrap (they do not do FM). I am forced to stream Planet Rock and Absolute Radio 80s over the Internet, which only works for the Hi-Fi system. It's useless in the bedroom, or when one is out mobile.
Quite! I worked in a small company from 1990 to 1995 and we were producing ETACS and AMPS test kit for the two international standards of the time. GSM had only just started to appear in 1995.
How about paying for a regulator who actually protects the radio spectrum and does its Market Surveillance job by removing non-EMC-compliant junk from the market-place before an un-suspecting public waste their hard earned money on it?! The current crop of self-serving civil servants that infest Riverside Towers are clearly not up to the job, so sack the lot of them, re-light the bonfire and start afresh with skilled engineers, technicians, and lawyers who are not frightened of the EU!
"The frequencies used to transmit TV in Slough are different from those used at Crystal Palace, to avoid interference, so the Slough frequencies are empty in Islington where they can be used for short-range wireless or point-to-point links."
WRONG! Check what you are going to write about Bill, before you make yourself look like an ejit! Slough is covered by Crystal Palace for TV, as it most of the surrounding area. The only transmitter in Slough is for analogue radio! If you want to use white-space TV frequencies in London, you will have to use those of the surrounding transmitters, like Sandy Heath.
I have spent quite a bit of money over the past few years on DAB radios and they have all recently been rendered useless - unless I want to listen to the BBC, which I don't! The fiasco that is Digital One should not have been allowed to happen, yet Ofcom seem complicit in helping/allowing the farce - but then Ofcom have been doing quite a good job of ruining the radio spectrum for years. I am now forced to stream Planet Rock/Absolute Radio 80s over the Internet in order to listen with any "quality". 80kbps and Mono is not progress. It's no better than a 6kHz-wide AM transmission! In the car, my retro-fit DAB radio is now sitting there dead - and may well end up removed. When I am driving locally, I might listen to BigglesFM, as it is somewhat more tolerable than the blandness of Heart/BBC. For all other trips, the iPod comes into its own!
Kelvin is an absolute temperature measurement, not a relative one; ergo, no need for the degrees symbol!
Opt for an LCD TV (not plasma!) with a DVB-T2 receiver and native 1920x1080 resolution, then you can receive High Definition - assuming your local transmitter is supporting it?!
There are a couple of ways you can experience interference, other than the usual blocking and pausing (my aerial is a mere 2.5km from Sandy Heath, which transmits 220kW, yet my TV and DVR still experience drop-outs!). If a 4G operator enables a tower (or builds a tower) that your aerial can see, the powerful signal (I say powerful - it's all relative to the power of your local TV transmitter(s)) may blind your receiver to the TV transmitter. Yagi aerials (used for TV) typically have a +/- 15 degree acceptance angle, so even if it is pointed dead-on to the TV transmitter, a nearby tower within the 'acceptance angle' could still cause a problem. Think of trying to look at a torch in the distance whilst some yob shines a laser in your eyes.
The other problem could come from a nearby 4G tower in your local area. As we are talking about milli-metric wavelengths (a quarter-wave at 800MHz is ~93mm), there is always the possibility of pick-up on the co-axial cable, or the aerial itself; even if it's pointing in the other direction.
Both of the problems above can be exacerbated by a wide-band aerial (possibly fitted to cover both analogue and digital transmissions) and/or an amplifier-splitter. Aerial amplifiers are often wide-band, covering Band II VHF (87.5 - 108.5MHz), Band III DAB (220 - 240MHz), and both Band IV and Band V TV (400 - 800MHz). A strong 4G signal could overload the amplifier and cause it to parasitically oscillate (poorly designed models can do that all of their own accord!). Result: no signal!
We have no real way of knowing if the 4G roll-out will affect few, or many. As Ofcom have no technical expertise, and have farmed out domestic radio and TV interference problems to the BBC, I am sure people are going to be left scratching their heads staring at a black mirror.
I hope you found this reasoned guidance?
CBer and non-bearded Radio Amateur.
I have been with Eclipse Internet since my local exchange had its ADSL switched on (over 10 years ago) and I've never looked back. They were a leap ahead of the NTHell service I had at the time!
Granted, they only re-sell BT's wholesale ADSL/VDSL products, and they have yet to catch up with the latest 80/20Mbps VDSL offerings, but, you can have up to two fixed-IP addresses for free; free reverse DNS for your mail server(s); use your own routers; and their call-centre is in Exeter, although sadly it is not open at weekends. Their support staff have always been very helpful; and a BT Openreach engineer commented to me on how detailed their fault reports were - more detailed than he received from BT!
You are correct that PLT splatters the mains with multiple OFDM carriers. When neighbouring devices are on the same mains-interconnects (i.e., the same phase-neutral between houses) it is the case of he-who-shouts-loudest. Many PLT devices simply ramp-up their transmit power to try and overcome other noise sources on the mains. I have read of cases where a noisy switched-mode power-supply, which also did not conform to the requisite EMC standards (filter components omitted by the manufacturer), rendered a PLT installation useless due to the noise levels on the mains!
Most of the "set-top-boxes" requiring PLT are missing a trick w.r.t. Wi-Fi. Is it really that hard to fit dual-band Wi-Fi and start using 5.8GHz? They could even include a neat little external aerial to tuck away behind the TV. Hardly rocket science!
Hardly "6 billion" making use of ham radio, TV's higher up the dial anyway ... are there really more radio hams than people wanting home networks? I doubt it. Just have an equipment buyback, trade all the ham gear in for a VoIP handset, problem solved ;-)
Billions of people in China, Russia, Africa, North and South America, and throughout Indo-Asia rely on shortwave radio to keep in touch. If you wish to deny them, please feel free to explain it to them. I am sure you will go down a storm!
Let's see your VoIP handset work in the middle of a field/up a mountain!?
The needs of the many............
The needs of ~6 billion people on the planet, who use radio to communicate, watch TV, listen to music, etc., outweighs the needs of a selfish minority who are too lazy to run a bit of Cat6!
The most effective thing to do is to insert an isolating transformer between your installation and the public grid. Another method is to wrap the incomer around a metal toroid which will block the higher frequency components.
You do realise that a common-mode choke rated at 100A would be the size of a fridge and require a sturdy concrete base? That will be the only way to stop conducted emissions from PLT in other houses!
Non-obviously it is possible to couple from one set of cables to another, so your neighbour could put a transmitter on their side of the wall and turn the power up...
You and your neighbour are likely to be connected to the same phase and neutral from the 3-phase in the street. It is only a matter of time before someone engages in a little neighbourly social-engineering and connects their PLT devices to their neighbour's. People do not understand how to secure their Wi-Fi or their routers, so PLT will be an easy target, AES256, or not!
Which "hobby" is more deserving?
The one that requires considerable technical study and examinations in order to obtain a licence from the government; plus the ability to set-up emergency communication-links during local/national/international disasters. My radios and aerials can cover anything from 20km around my home, to 2000km away in another country. Can your precious PLT answer the call for help?
FprEN50561-1:2012 is not a standard, it is still a draft that fails to meet the 'essential requirements' of the EMC Directive. It will not be adopted by the European Commission until it does meet the requirements. In the meantime, EN55022 Part B (residential usage) is still the applicable testing-standard for PLT. Of course, PLT manufacturers will continue to lie on their 'Declarations of Conformity' and claim compliance to incorrect testing-standards (EN55022 Part A - Industrial use only, not for domestic usage!) and non-existent "standards".
I think AmiPro from Lotus was the nuts! I was an avid power-user of AmiPro through the 90s. It blew the arse off Word, Works and Wordperfect, and it was such a shame when IBM ruined it. I could write long, complex technical manuals in AmiPro in minutes. Styles control, and the ability to switch styles with the press of a Function key is sadly lacking in today's wordy-processors. They are all rather clunky and awkward to use by comparison.
I so want this technology to work and become a sensible alternative to that crappy PLT! However, I can see problems that need to be overcome.
I assume you will be required to enter your post code into the device before it checks said databases? If it's going to work on tracing the IP address, I am in a variety of places in the country - according to Google. So if the IP trace suggests I am in Newbury and sets the device accordingly, it's going to cause a problem for me and my neighbours, who all receive from Sandy Heath.
And we already have the problems of LTE being pushed into the TV bands and the possibility of interference. I wonder how much testing has been carried out to ensure one of these devices parked near your TV will not wipe it out? I live 4.6km from Sandy Heath transmitter, have clear line-of-sight to the mast, and I still suffer blocking and drop-outs on my TV. Even if power is limited to 100mW, the near-field is still going to present a much stronger signal within the house than the local TV transmitters.
Who is actually demanding this? Is it the same parents who allow their children to play age-restricted violent video games and watch age-restricted violent films, yet baulk at the idea of them watching pr0n?
I challenged my friend about him allowing his 12-year-old son to play 18+ violent games. I suggested he might as well let him watch pr0n as well. "Ahh, that's different!" came the reply.
So can someone please answer me this: Since when has violence in games/TV/film been more acceptable to society than watching two people engaging in sex? After all, sex is how we all got here! All violence leads to is death.
The proposed "standard" (read: pack of lies) prEN5056-1:2012 has only been accepted by CENELEC, which was not a surprise considering the Working Group is made up of pro-PLT companies wanting to further their crap technology. This whole shambles taints anything CENELEC is now involved in!
prEN50561-1:2012 has to be accepted by the European Commission before it can be legally used; not that PLT companies stuck to the rules in the past! Many aspects of prEN50561-1:2012 contravene the 'Essential Requirements' of the Electromagnetic Compatibility Directive 2004/108/EC; something which the EC's own EMC adviser stated, before being completely ignored by CENELEC. The two cannot co-exist, so one of them will have to go. If it is the EMC Directive, you can kiss goodbye to any electronic device ever working correctly again!
prEN50561-1:2012 contains a number of mitigation "technologies", such as 'dynamic notching' and 'dynamic power control' - a tacit admission that PLT creates interference! Neither of these "technologies" exist, other than being mentioned in the "standard". Dynamic notching required the PLT device(s) to listen for other users of the radio spectrum. If all they can hear is other PLT units in the area, they will simply add to the interference. Can you see the irony and madness of that?!
Will it end with prEN5056-1:2012? If this nonsense is not kicked into touch, every manufacturer or trade body that does not want to conform to existing standards will use PLT as an excuse and a reason to demand their own "applicable standard". Everything the EMC Directive has sought to protect will be lost!
All laptops/routers/display screens with an external PSU should really run from 13.8Vdc. Why?
(i) Manufacturers are missing a trick with people who live on boats, go on boating/caravan holidays, or the road warriors/radio users on field-days who need to keep their laptops running. The ability to plug in to a vehicle/boat's 12V power system has long been overlooked. I appreciate this will mean many devices will have to curb their power-hungry nature, but this may force manufacturers to use better techniques and not scrimp on cheap and nasty electronics!
(ii) A very simple and efficient UPS can be created with a 13.8Vdc power supply and a standard lead-acid battery. There will be no conversion losses switching the voltage back up to 240Vac.
(iii) You could replace a number of wall-warts with one phat SMPS and a distribution system; like the 10 or 20A devices we use for CB/Amateur Radio.
Quite simple, when you think about it!
A harmonic (or multiples of) from an interfering device can just as easily be picked up on the co-axial braid and fed to your satellite box causing degradation/disruption of signal, interference to internal timing oscillators, or interference to digital processors. You are no more immune to RFI by using a satellite receiver than someone using DTT Freeview or digital cable!
Case in point: I had fitted some "buck-driven" LEDs to my vehicle. When the side-lights were switched on, my C.B. radio went nuts. The switcher circuit was supposed to operate around 5kHz, but the harmonics it created were spread right up to 27MHz, and possibly beyond.
"Mr Ronald L. Storrs (SE):
TELIA, the Swedish telecom operator and leading Nordic communication company, PLC service provider."
So no vested interest in PLT then?
And at least 22 - including the Project Leader - represent the PLT lobby (ILEVO, DS2, SONY, CTI, INTEL, SIEMENS PTD, TCA, ENF, EDF, UNIVERSITY DUISBURG-ESSEN, MAINNET, PPC, FRANCE TELECOM, BRITISH TELECOM, ENEL, INTELLON, ENA, TELIA)
Not trying to stack the deck in your favour at all!
There is a requirement under EU law that members states employ a Market Surveillance authority to oversee breaches of regulation, such as false CE declarations, contravention of the EMC directive, et al. Here in the UK, that responsibility falls to BIS, who in turn farm it out to Ofcom. Neither are interested in performing their statutory duty, so when Trading Standards seek their help to deal with manufacturers who are flouting the EMC regulations, Ofcom pat them on the head, tell them it's all OK, and TS have to let the case go. This is primarily how PLT has made such a large impact on the market, along with being handed out like sweets with BT Vision. Had the laws been adhered to, PLT would not be on the market!
PLT must be tested against EN55022 as it is Information Terminal Equipment, or ITE. The EU have stated that EN55022 is the correct standard to test against, so PLT manufacturers are lying on their EMC Declarations of Comformity and stating they pass EN55022 part A - which is for Industrial use only - will cause radio frequency interference. For domestic use, they should be tested against part B. This calls the whole DoC and CE system into question and renders it completely worthless!
Irrespective of EN55022, PLT must also pass the 'essential requirements' of the EU's EMC Directive 2004/108/EC; namely that it does not cause undue interference and stop a radio system from working as intended. The 'essential requirements' apply to all devices places on the market and PLT is no exception to that rule! prEN50561-1 cannot overrule the 'essential requirements', which it is seeking to do!
It should be noted that those driving prEN50561-1 through CENELEC are primarily from the PLT manufacturers. They are attempting to stack the deck in their favour and if prEN50561-1 becomes a standard, everything EN55022 stands to protect will be destroyed. Once that happens, other manufacturers will want to relax EMC rules for their products, and before long, all of you bleating on about Hams being a bunch of selfish <insert expletive here> will find your precious Internet connection dead thanks to interference from other electronic devices! Many of the proposed solutions for prEN50561 (smart notching, dynamic power control) either do not exist or are patent encumbered, so how can a standard for testing/compliance be produced when much of it is pie-in-the-sky?
What will it mean for you? Whilst the internationally agreed amateur radio bands and the CEPT Ciitizens' Band allocation will be protected by notches (a tacit admission that PLT creates radio interference), the rest of the HF band will be wiped, so if you like using ADSL/VDSL, listening to shortwave radio, or you need to communicate with aircraft over the Atlantic, or ships out at sea, you can forget it!
CFLs and strip lights should not be confused. CFLs use a handful of electronic components to "strike" the tube as they lack the same choke and starter found in strip-lights. When those electronics are of cheap and nasty Chinese manufacture, or they simply start to fail at the end of their life, they can create a wide-band spark-gap transmitter. This noise is fed back into the mains wiring where it finds a nice multi-path and multi-wavelength aerial. The user may not notice this if they do not engage in Medium Wave or Short Wave radio listening.
Alan Brown is correct, it is not just PLT, but CFLs, Plasma televisions, Switch Mode Power Supplies, LED buck-drivers, Thermostats, PWM controlled gas boilers, PV inverters and more which are all failing the Essential Requirements of the EU's EMC Directive (2004/108/EC) - they being to not cause unacceptable interference to radio systems that results in those radio systems being unusable.
Ironic is it not, that PLT can only operate correctly if everything else on the mains actually meets their EMC regulations and do not load the mains with noise!
Many of the new devices are listing compliance with EN55022 part A - which is for industrial use only (creates RF interference). They should be tested to part B (domestic use), but they would fail the conducted emissions tests, so they are lying on their Declaration of Conformity! Therefore, their CE mark is invalid as the product has not been correctly tested. Market Surveillance organisations in the EU are supposed to deal with breaches of this kind; but it's left to BIS/Ofcom in the UK, and they are completely useless!
Wrong on so many levels!
The meter in your property does not stop conducted emissions from mains-powered devices in your property from radiating back along the wires to other houses in your street, or vice-versa. If those mains cables are overhead, as in many villages, they will become aerials and radiate. In order to establish a clean mains signal, you would need a 100A-rated common-mode choke; and that would be the size of a fridge!
PLT's Orthogonal Frequency Division Multiplexing signal injected onto mains wiring is at such a high level that it radiates along all of the phases, neutrals and earths in your property (with the earths connecting to the neutrals at the incoming supply as part of the PME installation). This signal is also conducted to neighbouring properties who are on the same 415V phase, and all properties on the same transformer thanks to the common neutrals. This signal is further radiated along the earth wires of the properties and up each lamp-post in the area. This is physics and you cannot change that!
You are right, in that PLT is not a particularly large concern to Radio Amateurs if notched correctly; however, CB users are quite pissed as their allocated bands are wiped out. It should be noted that each part of the planet is divided into three ITU zones, and each zone has slightly different operating frequencies allocated for amateur radio. So a device with notches for ITU zone 3 is not necessarily any good in zone 2. Of course, with non-linear devices, such as switched-mode power-supplies on the main wiring, the notches become useless and fill up with intermodulation products.
As others have mentioned, with these devices failing to comply with the EMC Directive's "essential requirements", they fall over and lock up in the presence of powerful radio fields. A fully licensed radio amateur can legally transmit up to 400W - maybe more in the future if the UK's rules are harmonised. If your precious PLT devices fall over due to a lack of RF immunity, there is sod-all you can do about it, you have no grounds for complaint and no-one to complain to!!
A work colleague used to suggest I had a large carbon footprint because I drove a sports car. I suggested his was 20 times larger than mine as I did not have a wife or two kids to feed, cloth and heat. He didn't like that!
Last time I checked, my estate is littered with cabling cabinets from the NTHell days (now Virgin Media) and the scars in the pavements are still clear to see in many places. VM like to claim they are offering fibre-optic Internet access, but we all know it's over copper co-ax. Like BT, they will have to re-do their cabinets if they want to offer FTTP.
Openreach (well, their contractors) have been installing their FTTC boxes all over my town and my ISP tells me it's available (just waiting on them to sort their daft business pricing). It will make a change from being stuck on 8192/448 for the past 8 years, but I would prefer someone to blow fibre up to my house!
Is it legal for the council to ban photography in a school? Is that actually written down in Scottish statute, or is this another case of civil servants overstepping their bounds?
...is a bunch of un-elected, un-accountable civil servants who, with some (mis)direction from BIS, have chosen which laws they will enforce and which laws they will ignore. Ofcom's model of operation has been to generate cash for the exchequer and sod-all who get in its way!
Let us take the case of Electro Magnetic Compatibility. It is law, written into UK statute from EU Directive 2004/108/EC. The EMC regs were created in a time (1980s) when all sorts of electronic devices were bursting on to the market - and they were interfering with each other. EMC regulations set limits for generation of interference (some is allowed) and immunity from interference (your computer doesn't crash when you turn on a light). These are neatly rounded off with the essential requirements that devices do not wipe out important services, such as radio.
Add to the above, CE testing and certification. If a product is to be placed on the EU market, it must pass standardised tests to ensure CE compliance; and some of these include EMC tests for electronic devices. Member states are required to provide a Market Surveillance facility where products are monitored, and where necessary, tested for compliance. In the UK, that responsibility is handed down from BIS to Ofcom. So if you report a faulty electronic device to Trading Standards, they are supposed to be able to call on Ofcom's "expertise" to determine if the device meets the essential requirements of the EMC directive.
So why is the country in such a mess and the radio spectrum polluted with non-EMC compliant Power Line Technology (PLT), plasma TVs, switch-mode power supplies, and CFLs (to name a few)? Well, the buck stops at Ofcom. In cases where Trading Standards have sought help, Ofcom have said it's all OK and no laws are being broken, so TS cannot act. In a case where a computer SMPS was reported to TS, they could only act on the Low Voltage Directive and the supplier could only be warned. Had Ofcom used their legal EMC powers, the supplier would have faced court!
If Ofcom had acted correctly over the past 10 years, Power Line Technology would never had left the lab, as it cannot pass the essential requirements unless it is turned off; Panasonic would not be in radio-users' cross hairs over their Viera range of radio-noisy plasma televisions; cheap and nasty switched-mode power-supplies supplied without filtering components would be caught and their suppliers and manufacturers fined; and we would not be calling for Ofcom to be scrapped.
It should be noted that the RSGB cannot take over interference investigation or EMC compliance enforcement as they are not a legally bound entity. There is however, nothing stopping the current government from carrying out their pledge to remove Ofcom, returns its regulatory function to DMCS, and create a new organisation tasked with [radio] spectrum management and EMC compliance. The fines levied on all of the non-compliant manufacturers should fund the organisation for some years!
"But given the state of geography teaching today, that's a moot point."
I only saw a clip of Educating Essex as it was shown on Anglia News. When the blonde girl, whom I suspect to have been around 14 or 15, suddenly asks what Pi is and where it came from, I realised society is doomed! Another education documentary was asking kids to identify towns from dots on a map. One girl complained that if she wanted to know where Exeter was, she would get on a train. I would have loved to dump her in London and tell her to find her way!
