472-479 kHz Amateur Allocation Passes WRC-12

ARRL:

Amateur Radio Gets Secondary MF Allocation at WRC-12

02/14/2012

It’s official -- delegates attending the 2012 World Radiocommunication Conference (WRC-12) have approved a new 7-kilohertz-wide secondary allocation between 472-479 kHz for the Amateur Radio Service. Agenda Item 1.23 had both its first and second readings in Plenary Session on Tuesday, February 14; to become part of the ITU’s Radio Regulations, each Agenda Item must be read twice in Plenary Session. While the Final Acts will be signed on Friday, February 17 at the close of the Conference, the new allocation will not take effect until it is entered into the Radio Regulations. No date has been set for this, but it is unlikely to be earlier than January 1, 2013. In any case, no amateur can use the band until his or her national regulations are revised to implement the allocation.

...

Agenda Item 1.23 originally called for a 15-kilohertz-wide spectrum in parts of the band 415-526.5 kHz, taking into account the need to protect existing services. But according to ARRL Chief Executive Officer David Sumner, K1ZZ, this was in conflict with the Maritime Mobile Service. WRC-12 delegates approved Agenda Item 1.10, which called for a worldwide exclusive allocation to the Maritime Mobile Service of 495-505 kHz. Discussion of this allocation to Maritime Mobile "has been in the works throughout the conference preparation (i.e. since 2008)," Sumner explained, "and was the reason why the MF amateur allocation could not be made in this band as some amateurs had hoped. That’s why we had to look elsewhere and is what put us in conflict with aeronautical radionavigation."

600-Meter Amateur Passes Committee, Goes to WRC-12 Plenary

ARRL:


On the afternoon of Tuesday, February 7 (Geneva time), Committee 4 of the 2012 World Radiocommunication Conference (WRC-12) approved Option 1 to satisfy Agenda Item 1.23, with minor editorial amendments to the text received from Working Group 4C. Option 1 calls for a worldwide secondary allocation to the Amateur Service at 472-479 kHz, with a power limit of 1 W EIRP, with a provision for administrations to permit up to 5 W EIRP for stations located more than 800 km from certain countries that wish to protect their aeronautical radionavigation service (non-directional beacons) from any possible interference. Option 2 was NOC (no change to the current rules).

In keeping with the rules of the Conference, Committee decisions must be read twice in Plenary session; the decision of the Conference is not final until after second reading in Plenary. According to ARRL Chief Executive Officer David Sumner, K1ZZ, quite a few additional administrations -- mainly in the former Soviet Union and Arab states -- will be adding their country names to the Footnotes prior to consideration in Plenary.

(ITU footnotes number in the hundreds.  They are a means of achieving consensus on international radio regulations by allowing exceptions for countries with concerns which would otherwise force them to vote against an agenda item in Plenary Session.)

Major BPL Company to Shut Down

In the latest of a string of commercial Broadband over Power Lines (BPL) failures, International Broadband Electric Communications, Inc. (IBEC) is dropping its rural Internet service this month.

In a 12/23/11 letter over the signature of Scott E. Lee, the CEO, IBEC states:

It is with a very heavy heart, that we must inform you that IBEC will no longer be in a position to provide Internet service to your area.

We encourage all of you to pursue other options for your internet services as soon as possible. This includes your email service if you have an active @BPL,COOP email account. Please move to another email service as soon as possible.

...

Our demise, started with the April 27th storms of this year in Alabama, which destroyed over 3.2 Million in assets, which our Insurance Provider (CHUB) has refused to pay. We also lost a critical investment from an Investor commitment, due to these storms, putting IBEC into a negative financial situation. IBEC pursued assistance from RUS (our Federal Creditor at US Department of Agriculture), our vendors and endless potential buyers after these events without success.

It is doubtful that radio fans will be as heavy-hearted.  One might remember IBEC for another reason.  ARRL:

More than a year ago, the ARRL filed a complaint with the FCC, documenting ongoing harmful interference and egregious rules violations by IBEC-installed BPL systems in Virginia, Pennsylvania and Indiana. The ARRL had requested that the FCC “initiate immediately an enforcement proceeding regarding these BPL systems, and cause them to cease operation until such time as they are each in full compliance with the Commission’s Rules.” The ARRL even discovered IBEC BPL systems in operation that are not listed in the online BPL database -- another clear violation of the FCC rules, which require listing 30 days prior to initiation of service. To the ARRL’s knowledge, even as of today, the FCC has taken no enforcement action to correct these violations.

ARRL also notes that IBEC was the last BPL provider in the US that didn't notch amateur bands (a violation of FCC regulations).

UK Ofcom Caught Lying on BPL/PLT (No April Fool)

Ofcom, the UK "FCC," has been caught in a lie, or at least a strong political spin, regarding the legality of a popular device used widely in that country for in-home Broadband over Power Lines/ Power Line Telecomm (BPL/PLT).

On the record, Ofcom has long maintained the position that the equipment operates within the law as it exists in that country. However, a legal request for documents has recently turned up a test result commissioned by Ofcom, which was apparently suppressed when it came back showing the units well in excess of electromagnetic compatibility standards.

At present, it strongly appears that a major UK regulatory agency developed a policy for political rather than engineering reasons, and then spent years intentionally covering up data in conflict with this policy. There, as here, the word for this is corruption.

Here's the first part of a story in The Register UK:

Ofcom forced to publish tests on dodgy radio kit
FOI request prompts action
By Bill Ray
Posted in Wireless, 31st March 2011 12:07 GMT

Ofcom has been forced to disclose its own tests showing that powerline networking kit does breach the European EMC Directive, but still won't do anything to enforce compliance.

Despite claiming there was no evidence that PLT kit built by Comtrend and supplied by BT was breaching EU rules on electromagnetic emissions, the regulator has now been forced by a Freedom of Information request to publish independent research, commissioned by them, which shows exactly that.

The request was pursued by Peter Walker, a radio amateur who eventually had to take Ofcom to an ICO Tribunal to get the regulator to hand over the study - which appears to contradict Ofcom's line in stating that the equipment tested, which was supplied by Ofcom, does not comply with the standards required by EU legislation.

ARRL Shows IBEC BPL Systems Are Interfering, Violating FCC Rules

[Hugh's note: IBEC stands for International Broadband Electric Communications, Inc. Contrary to what you have been told about Broadband over Power Lines (BPL), it remains commercially viable in "underserved" rural markets where DSL and cable are not practical options. IBEC's equipment is fully certified under current FCC rules, and the company offers turnkey solutions ready for immediate deployment by any power company. Everything was supposed to be fine, but according to the ARRL, there is some trouble in paradise. Read on.]

12/29/2010

ARRL, the national association for Amateur Radio has filed a complaint with the Federal Communications Commission documenting ongoing harmful interference and egregious rules violations by Broadband over Power Lines (BPL) systems installed by IBEC, Inc. in Virginia, Pennsylvania, and Indiana. The ARRL has requested that the FCC “initiate immediately an enforcement proceeding regarding these BPL systems, and cause them to cease operation until such time as they are each in full compliance with the Commission’s Rules.”

Contrary to earlier representations to the ARRL and to statements in the online BPL database, IBEC’s systems in these locations are not universally notching the Amateur bands as is necessary in order to avoid emissions at levels that are likely to cause harmful interference to licensed Amateur Radio stations. In fact, measurements by ARRL staff and confirmed independently show that IBEC systems are not even notching the aeronautical bands that the FCC rules require BPL systems to avoid and are operating at power levels that cause radiation well in excess of the FCC limits.

The ARRL even discovered IBEC BPL systems in operation that are not listed in the online BPL database – another clear violation of the FCC rules, which require listing 30 days prior to initiation of service.

RSGB Responds on PLT/PLC Report

The Radio Society of Great Britain has posted the following response to inquiries about its position on the recently published consulting report regarding the electromagnetic compatibility issues surrounding home power line communications in the UK.

This discussion is on the UK QRM group on Yahoo. From the start, this group has played a key role in the discussion of this issue among hams and SWLs in the United Kingdom. It was started by long time Utility World contributor Mike in West Sussex, who has hung in there despite personal tragedies which would have defeated lesser people.

Given the context, we should best regard this as a semi off the record statement. Here you go:
I have seen several requests here for a comment from someone in RSGB on all this.

In the GB2RS script for this week should be the following:

Ofcom has this week published its long-awaited report "The Likelihood and Extent of Radio Frequency Interference from In-Home PLT Devices" This 156 page report assesses the likelihood of interference to various users of the radio spectrum over the next decade. The main conclusion is that action is needed to reduce the interference footprint of PLT devices. This action could take various forms, and the Society is considering the report in detail prior to initiating discussions with Ofcom about the follow-on actions it intends to take. We expect the position to become clearer over the next few weeks and months.

As background, there are a number of issues to consider about the report's recommendations, not the least is whether Ofcom has accepted them! Beyond that there are questions about the effectiveness of the mitigation measures which PA recommend, and whether they go anywhere near meeting the essential requirements of the EMCD.

RSGB is considering all these matters, and will make its views known in due course.

UK Ofcom Publishes Key PLT/PLC Report

A long-awaited report from PA Consulting Group, as commissioned by the UK Office of Communications (Ofcom), has been released.

The report is entitled "The Likelihood and Extent of Radio Frequency Interference from In-Home PLT Devices." It carries a publication date of "21 June 2010."

This is a dense, highly detailed document with 156 pages. However, its conclusions are clearly written and easy to understand.

Basically, if nothing changes in the design of the home network adapters sold to the public, the UK can expect significant degradation of many radio systems and some hardwired services such as DSL, by 2020. Affected radio comm spectrum would include nearly all of HF outside amateur bands, and most of VHF.

PA, however, remains hopeful that design changes can reduce such interference.

Here are the most relevant parts from the conclusions in the summary at the beginning. Those wanting to read more and make their own conclusions can get the entire document at this link.

Page 1:

1 Executive summary

Power Line Telecommunications (PLT) devices are used for data distribution in the home

Power Line Telecommunications (PLT) is the collective term for various forms of communication over wiring used for supplying electricity (termed the 'mains' wiring throughout this report). The most recent developments in PLT devices address the consumer market for in home connectivity as an alternative to WiFi or data cabling. It is these in-home PLT devices that are the specific focus of this study. In-home PLT devices are growing in popularity and, in particular, their use in BT Vision installations in the UK has made the UK one of the biggest users of in-home PLT devices in Europe.

Ofcom has received complaints of interference caused by PLT devices and has requested this study The majority of PLT devices on the market today operate at HF frequencies and, while they are not intended to radiate, there is evidence of interference to other HF users which has resulted in a number of complaints to Ofcom. While most of these complaints have been resolved, Ofcom is concerned that the problem may grow as the number of PLT devices deployed increases over time. Higher data rate PLT devices operating up to 300MHz have also started to emerge in the UK market and so potential interference at VHF is also a concern.

Ofcom has asked PA to assess the likelihood and impact of RF interference from in-home PLT devices over the next 5 to 10 years.

Our results show that users of sensitive radio systems may increasingly suffer interference from PLT devices

In this study we have taken a statistical approach to quantifying the probability of interference occurring as PLT devices become more commonplace. We have concluded that if uptake increases in line with our market forecasts, there will be a high probability of interference to some existing spectrum users at both HF and VHF by 2020 if PLT device features do not change from those currently implemented.

However, within this timescale, in addition to the existing practice of notching International Amateur Radio Union (IARU) bands, interference mitigation features such as power control and smart notching are expected to have been implemented in PLT devices. Our results indicate that the introduction of these features will be enough to reduce interference to negligible levels in the majority of these cases. The exception to this is the safety critical aeronautical bands which we recommend are notched by default rather than by smart notching. [Smart notching only responds to very strong and persistent signals like SWBC, not weak USB comm. -Hugh]

And Page 3:

It is important that mitigating features are implemented in future PLT devices.

The majority of PLT devices in the UK to date have been issued as part of the BT Vision package; however, there is churn in this market, and it should not be assumed that the existing installed base is traceable or could be updated to incorporate these features. We do however assume that the current practice of PLT devices being upgraded in cases where they have been identified by Ofcom as sources of interference will continue and ensure that the existing installed base is gradually replaced where needed.

While power control and smart notching are already part of the product roadmaps of the PLT vendors that we consulted as part of this study, we recommend that where possible the introduction of these features is formalised to ensure that their introduction can be relied upon.

ITU to focus on emergency communications

Business Standard, India:

2010-06-05 01:00:00

The International Telecommunication Union (ITU)’s World Telecommunication Development Conference (WTDC), which after 12 days of deliberations concluded here on Friday, adopted the Hyderabad Action Plan, outlining a road map to foster the global development of information and communication technology (ICT) networks and services over the next four years with more emphasis on emergency telecommunications.

Telecommunications and ICTs also play a critical role in disaster detection, early warning, preparedness, response and recovery. The Hyderabad declaration calls upon administrations to support polices and strategies that facilitate the use of telecommunications and ICTs for disaster management, in particular radiocommunications, said ITU secretary-general Hanadoun Toure.

"ICTs can save lives and help reduce the impact of natural disasters that could impede sustainable development. ITU has played a critical role in restoring telecommunications in disaster-hit areas around the world and was one of the early responders in the aftermath of the devastating earthquake in Haiti earlier this year," he added.

Power Line Communications on agenda at ITU

From Southgate Amateur Radio Club, UK:
Power Line Communications on agenda at ITU

ITU Working Parties 1A and 1B will meet in Geneva between June 21 and 28. A major item of discussion will be protection of radio services from interference from Power Line Communications (PLC) also known as PLT or BPL.

IARU has already contributed to the ITU-R report SM2158 “ Impact of power line telecommunication systems on radiocommunication systems operating in the LF, MF, HF and VHF bands below 80 MHz“ where the acceptable criteria for degradation of the HF radio noise floor caused by PLT is defined as being 0.5dB. Work in WP1A will concentrate on the protection of radio services from the effects of PLT in range from 80 to 200MHz.

The IARU delegate to SG1 and its working parties is Peter Chadwick G3RZP: three input contributions have been prepared for this meeting. One of these is a report on the effects of intermodulation in power supplies causing the amateur band frequency notches in the PLT spectrum to be degraded: this report has been prepared from the work by Richard Marshall, G3SBA published in the RSGB RadCom magazine, and also points out the difficulty such effects could have on the PLT system itself.

A further input establishes the protection criteria for amateur stations operating in the 2 metre band: Ian White, GM3SEK contributed to this input, and it is considered that the amateur and amateur satellite services require protection such that PLT interference does not exceed -45dB m V/m in the main lobe of the antenna, with a separation between antenna and the PLT installation being at least 10 metres.

The third input is of a more general character showing that there are a number of non-amateur services that could suffer interference from PLT or its harmonics, such applications including social alarms for the elderly, pagers, medical implant telemetry, as well as broadcast, and when aggregation of radiation is concerned, aircraft navigation and communications. When the differences in range between PLT and mains leads and the social alarms and medical implant ‘base’ stations etc., are taken into account, the acceptable levels of radiation to protect the amateur services are of the same order as those needed to protect these other services.

In another posting to this club's excellent web site, VK3PC notes that "Access BPL" is for all purposes extinct in Australia. He says that it never really reached a critical mass in the market down there, and it is rapidly being abandoned for other systems.

Thankfully, a similar process seems to be at work in the USA, with the infamous Manassas system being the latest victim.

"Access BPL" differs from PLC aka PLT aka In-Home BPL in that it uses the power company's wires, which have been demonstrated to be excellent (if inadvertent) transmitting antennas. Less is known about the real-world, non-laboratory-conditions RF emission from PLC/ PLT/ In-Home BPL. This completely different system uses the house wiring to distribute high-bandwidth applications such as video on demand. Originally, wi-fi was not up to this task, though the technology is evolving rapidly.

While a bad situation has existed for some years in the UK, compounded by regulatory abdication, the problems there may or may not ever actually happen in the United States. US house wiring differs considerably from the 200-volt loops with fused plugs that are still fairly common in the UK.

RSGB Challenges UK Ofcom Regarding Home Powerline Telecom

For the first time, the Radio Society of Great Britain (RSGB) has directly challenged the UK's Office of Communication (Ofcom), regarding its technical standards and regulatory policies in the matter of home power line communication (PLA/PLT) interference to licensed radio services.

In a letter written to Ofcom Chairman Colette Bowe, over the signature of RSGB Director Donald F. Beattie, the RSGB gives a detailed response to Ofcom's official statement made last September. RSGB takes issue with some of the Ofcom assertions in the September statement, and asks for clarification in a number of other areas.

Excerpts:

"Ofcom believes the electromagnetic disturbance produced by this technology is an inevitable by‐product of its operation and not attributed to poor design or manufacturing."

We disagree ‐ there is poor design involved here. The trade‐off between headline data rate and emission level is wrongly set. It is only an inevitable by‐product of its operation if that operation is aimed at transmitting an unreasonably high data rate.

...

Emissions are an inevitable consequence of an unsuitable technology.

...

Our underlying concern is that the invaluable asset of the radio spectrum is being progressively sacrificed to allow a polluting technology to flourish, based on the mistaken argument that there is public good involved. Arguments are being mustered to support this strategy, which have little or no basis in fact. We see the inevitable consequence of the current policy as being the consignment of the High Frequency Radio Spectrum to history. Once this has happened, it will not be possible to reverse matters. International standards exist to provide for sensible coexistence of services, and the RSGB contends that the setting aside of such standards for expediency is not in the long‐term public interest.

The full text of this letter, with plenty of numbers, cites, and technical details, is available at the RSGB web site. One can also find details regarding the RSGB Spectrum Defence Fund.

Expect this controversy to heat up. Due to the ever-higher data speeds required in new broadband plans, manufacturers of next-generation PLT units are using much wider RF bandwidths, well into VHF. It's not just about HF any more.

Some SW Broadcasters Still In 40 Meters

It would appear that the new rules which move broadcasting to above 7300 kHz are being ignored in China. Asian listeners are hearing multiple broadcast programs, often on the same channel, pretty much as before.

7100-7200 Now Amateur

At the end of March, the long awaited radio regulation change became final on the spectrum between 7100 and 7200 kHz in ITU Regions 1 and 3.

This is the 40 meter amateur band. Amateurs are now primary in this allocation. International broadcast stations should have all moved out, though it's likely a few stragglers remain. However, now they are intruders, not valid authorized users.

In exchange, the spectrum above this band, which goes to 7300 in the Western Hemisphere, is now primarily broadcasting. Canadian time station CHU changed frequency at the beginning of this year as a result of broadcast interference to this formerly fixed-service primary allocation. The new frequency is 7850 kHz R3E (reduced-carrier upper sideband).

New PLT Product Brings HF Doom A Step Closer

Let's forget the tech speak, and the engineering talk of decibels and signal levels.

Here's what is happening, in plain English:

What we are facing is the design and high-powered marketing of a whole large family of new products which cannot operate normally without ENDING SHORT WAVE RADIO, FOREVER.

Period.

It's no more technical, or esoteric than that. NO MORE SHORT WAVE. EVER. The entire HF band, 2 to 29 megahertz, JAMMED by the most highly distributed system of wideband HF noise generators EVER INVENTED. If WE do not act proactively, NOW, these will be in every building in the industrialized world.

Is that simple enough?

The latest such invention being heavily marketed, amid glowing praise in magazines, sends audio through power lines using HF carriers at a high enough power to jam the entire spectrum in a radius of hundreds or thousands of feet depending on conditions.

This particular product was tested by someone on the UKQRM list and was found to have NO NOTCHES! Amateur radio frequencies are NOT PROTECTED! This matches the experience in Portugal, where products are distributed without these notches.

Got that? No more utility. No more ham. No more use of marine USB while dockside. NO MORE SHORT WAVE RADIO, ANYWHERE IN THE INDUSTRIALIZED WORLD, EVER AGAIN.

I don't know why I bother with this cause. The apathy is complete, and the regulatory indifference is shocking. Unless a movement starts, right now, involving people who traditionally distrust political movements, it will be over. The regulatory agencies will say, well, that's the breaks. Sorry about that.

The people of this Earth will lose the most accessible and democratic (small d) communication medium ever invented. This will have a tragic effect on all history.

Now... is that clear enough?

US Congress Investigates "Dysfunctional" FCC

We were right all along. Or at least that's the conclusion of a Congressional investigating committee, which confirms serious malfeasance at the US Federal Communications Commission.

Their new majority report paints a picture of an opaque FCC, with a culture of fear and a tendency to suppress data conflicting with politically motivated decisions. Gee, this sounds quite a bit like many other parts of the Bush administration, does it not?

Here are some relevant parts of a news report posted to the ARRL web site:

On Tuesday, December 9, the House Committee on Energy and Commerce -- the congressional committee that oversees the Federal Communications Commission -- released its majority staff report "on the bipartisan investigation of the FCC's regulatory processes and management practices." The report -- Deception and Distrust: The Federal Communications Commission under Chairman Kevin J. Martin -- stated that the investigation was prompted "by allegations to the effect that [FCC] Chairman Kevin J. Martin has abused FCC procedures by manipulating or suppressing reports, data and information."

...

Representative John D. Dingell (D-MI), Chairman of the Committee on Energy and Commerce echoed Stupak's concerns: "Any of these findings, individually, are cause for concern. Together, the findings suggest that, in recent years, the FCC has operated in a dysfunctional manner and Commission business has suffered as a result. It is my hope that the new FCC Chairman will find this report instructive and that it will prove useful in helping the Commission avoid making the same mistakes."



But the best parts concern the FCC's deliberate ignoring of data that conflicted with its allegedly prejudiced decision on Broadband over Power Lines (BPL):

Concerning BPL, the report alleges that FCC officials "ignored complaints of radio frequency interference caused by BPL high-speed Internet technology, delayed an enforcement investigation for two years and improperly withheld engineering data regarding BPL from the public."

The report found that in October 2004, as then-Chairman Michael Powell issued his final rule "defining BPL access and setting technical and administrative requirements to protect licensed radio operators from harmful interference," the FCC "withheld from the public certain engineering reports on which it relied in promulgating the rule" from the final rule and order.

Even though the BPL rules were adopted during Powell's tenure, the report found that "it was under Chairman Martin that the Enforcement Bureau and the General Counsel continued to withhold the redacted engineering reports and insisted on doing so in the course of the ensuing litigation [with the ARRL]."


Farther down, Martin is accused of lying to Congress:

The report also showed instances of where Chairman Martin "manipulated, withheld or suppressed data, reports and information," and said Martin's "manipulation [of another report] may have damaged the credibility of the Commission, and certainly undermined the integrity of the staff. Moreover, it was done with the purpose of affecting the congressional decision-making, in that it was issued as a report to Congress."


It is certainly everyone's hope that a new broom in Washington can sweep away some of these wannabe communication lobbyists who have so damaged the FCC.

IARU Region 1 Passes New 40 Meter Bandplan

The International Amateur Radio Union (IARU) concluded its meeting in November with an agreement on a new voluntary band plan for the expanded 40 meter amateur band.

IARU regions coincide with those of the International Telecommunications Union (ITU). Region 1 is Europe, Africa, the Middle East, and all of Russia east to its Bering Strait border with (gasp) the United States. Region 2 is North and South America, plus Greenland. Region 3 is Asia (minus Asiatic Russia), the Central and South Pacific, Australia, and New Zealand. Antarctica and the Arctic are split up accordingly, as the lines run clear to the poles.

On March 29, 2009, an ITU agreement will kick in, expanding 40 meters in Region 1 from 7000-7100 kHz to 7000-7200. AM broadcasters in Region 1 will no longer be coordinated in this part of the "41 meter band," though it is not known whether all will actually move anytime soon. Furthermore, broadcasters in Region 3 will not have to move unless interference from legally operating amateurs becomes a problem.

The major change for hams is to move most voice operation above 7100 kHz, somewhat more in harmony with the United States rules. Night time 40 meter users in the US will hopefully not be required as often to work crossband or cross-mode to contact voice DX stations. However many countries don't have required band segments by mode, and band plans are voluntary in such cases.

Here's the band plan:

7.000-7.025 CW, contest preferred (existing prime DX-chasing segment worldwide)
7.025-7.040 CW QRP, Center of Activity 7030
7.040-7.047 Narrow band digital (PSK31, etc)
7.047-7.050 Narrow band digital, auto allowed
7.050-7.053 All digital, auto allowed
7.053-7.060 All digital
7.060-7.100 All modes, 7070 digital voice, 7090 SSB QRP
7.100-7.130 All modes, Region 1 Center of Activity 7110
7.130-7.200 All modes, SSB contest preferred, SSTV 7165
7.175-7.200 All modes, priority for intercontinental

Editorial: UK Ofcom Screws the Pooch On PLT!

This letter from the UK Office of Communications, as reprinted on the UKQRM mailing list, shows once again that the USA has no monopoly on corporate butt-saving by government regulatory agencies. This masterpiece, in fact, surpasses even the most incredible stuff churned out by our FCC, and that is no small achievement.

Whilst there is evidence that some PLT apparatus fails to meet the ETSI Harmonised Standard EN 55022, there insufficient evidence [sic] that the emissions generated are causing harmful interference, more generally, to consumers.

The actual number of complaints received by Ofcom attributed to power line telecommunications equipment remains extremely low in comparison to the number of products in use. In September 2008, Ofcom received 6 interference reports from radio enthusiasts, and this was preceded by 15 in August; prior to this, there were around 20 others. I understand that all interference cases have either been or are being resolved.

We have considered your comments regarding the Comtrend/BT product, and generic PLT equipment; and references to provisions that allow for enforcement action to be taken.

Ofcom do not consider that the current situation justifies taking enforcement action to remove PLT apparatus from the market. In making this decision, Ofcom have considered our statutory duties and functions included in the Communications Act 2003 and EMC Regulations 2006.

For enforcement action to remove PLT equipment to be considered proportionate, Ofcom would need to establish that the apparatus does not meet the EMC essential requirements and generates harmful interference.

At this time we consider a proportionate response to be, to deal with the complaints of interference received on as and when they arise on a case-by-case basis.

We do, of course, reserve the right to adapt our enforcement policy to meet with any change in the circumstances, for example, where we observe a significant increase in the number of interference cases received (where PLT emissions are proven to be excessive); or, of course, due to a change in the type of spectrum user being affected by the interference (a good example would be a service concerned with national safety and security). Naturally, we would need to consult with BERR regarding any change in our enforcement approach.

By this logic, I guess a company flooding the market with baby formula known by regulators to contain poison would be within the law if only 40 or so families complained when their babies died.

RSGB Letter to UK Authorities Re:PLC

The Radio Society of Great Britain has sent a letter to the British Ofcom regarding the Society's perception of a weak response on the dire matter of Power Line Communications.

While RSGB has expressed considerable concern over strong HF interference caused by the wide deployment of home Ethernet power line adapters, Ofcom has spent two years making vague excuses based on a legal issue regarding the European Union.

As anyone who has been following the situation knows, politicians worldwide have been reluctant to rule decisively in PLC matters. Generally, they have preferred to see what the marketplace does, rather than be perceived as against "new technology." This has led to the approval by Germany of home computer networking gear that is clearly in violation of ITU regulations regarding access to spectrum. Further, these units do not generally meet their claimed specs as submitted for CE certification. These specs come from a self-test in a best-case situation which is unlikely to be replicated in the real world.

Here is a portion of the RSGB letter as published on the Society web site:

The RSGB has recently received a reply from Ofcom in response to a PLT complaint made almost two years ago. The Society has in turn expressed its’ dismay at the contents of this letter and has responded accordingly with a letter from the President. The following edited extract will hopefully show that the Society is not about to roll over and accept what amounts to “shoddy service” from the regulator -

“The Radio Society of Great Britain understands that as the product in question was declared compliant in Germany, Ofcom extended the usual courtesy of asking BNetzA to investigate as the home authority in the first instance. You say that BNetzA has investigated but decided not to take enforcement action but you have given no reasons. The implication is that you will not be taking any further action. However as the product is available from UK outlets we do request that you continue to investigate our complaint of non-compliance. You will know that if your investigations confirm the non-compliance, the fact that the German authorities have chosen not to take enforcement action is not a bar to the UK doing so under the principle of national subsidiarity. The integrity of New Approach Directives is in fact dependent on Member States acting where non-compliance is found. The procedure under Article 10 of the EMC Directive or Article 9 of the RTTE Directive provides the method by which Member States must notify the Commission of such independent action.

The Society submitted a detailed complaint case nearly two years ago and is still awaiting positive action by the UK regulatory authorities. You will appreciate that there is considerable frustration among HF radio users about this matter, many of whom are members of the RSGB. This delay, attributed to restructuring, is frankly deplorable, unprofessional and certainly does not reflect well on the neutrality of the administration or the stated Statutory Duty of “Ensuring the optimal use of the electro-magnetic spectrum”. We believe the recent increase in reported incidents of interference received from licensed radio amateurs and short-wave broadcast listeners alike and attributed to units from various manufacturers represents only a small percentage of those suffering with this problem, with the majority not yet aware of what is causing the harmful interference to their reception.
It is understood a number of sufferers have already written to their MPs and MEPs in respect to this problem and no doubt these letters will reach your desk in due course. In the meantime we look forward to hearing of the results of your investigations as referred to above and the pursuance of the “enforcement policy in line with stakeholders needs””.

UK QRM Group Mentioned in Amateur Radio Newsline

Amateur Radio Newsline is a respected (and copyrighted) voice broadcast with MP3 files and written transcripts available here. It is heard by thousands of hams worldwide.

This week's Newsline mentioned the PLC interference situation in the UK:

Radio Netherlands reports that a new Yahoo Group called UKQRM has been formed. This, as a meeting place for those who use the high frequency bands and who are suffering from interference caused by Broadband over Power Lines or BPL.

In announcing the group, Radio Netherlands Worldwide's Andy Sennitt is quoted as saying that the traditional DX clubs have been very slow to latch-on to the threat posed by this technology. Because of this it is encouraging to see that at least some listeners in the United Kingdom are trying to raise awareness of the problem.

More On PLC Trouble in Portugal

More ominous news from Portugal via UKQRM:

Hi everybody,

I'm Joe, SWL CT0347 and CT4AN, Amateur for several decades and space telecom researcher. Thanks to the owner and moderators for giving me the opportunity to be a member of your Group.

I am very worry about the situation of using main power lines (inside houses or not) with other kind of signals not beeing 50Hz.In my country, Portugal, we have now a new big problem with that kind of signal on wide & broadband TV distribution and Internet services. A few years ago, we had our Power Company trying to establish BPL but, with the strong oposition of SWL, Ham operators and CB's, we finished their business.

Now we have PLC distribution inside the houses, for MEO services (broadband Internet, TV and phone) made by Portuguese Telecom PT, using [law suit avoidance mode -hugh] plc boxes; we are beeing all blocked on HF - all short wave listening, CB band, Amateur HF Bands, etc are getting impossible with the noise produced by those equipments, covering on full data-streem all HF from 2MHz till 35 MHz. It's a junk ... and THE END OF OUR SHORTWAVES.

Even with "gaps" on it's spectrum, located only in some Amateur HF Bands, the QRM is very-very strong, with levels of >80 dB/uV detected in a distance of 200 meters from the focus. The "notch" (when in operation ...) have 40dB of attenuation in the best, that is insuficient to preserve the noise-floor level needed for DX communications on Shortwave Bands (-110dBm minimum). That's a mess ...I would like to hear from you about your PLC experiences in your countries, with your PTT's Authorities, with your Clubs and Associations, and exchange information and possible common solutions and strifes.

GOOD DX'S BUT ... WITHOUT PLC AND OTHER DECREPIT TECHNOLOGY !!
