SSE interview – the interference issue

From the interview:
“The report is incorrect in that implies that there has been an interference complaint about PLC – I think the slide is ambiguous and that the interference was with DSL or was being demonstrated as potential.”

Well slide 15 is titled “PLC measurements relative to ambient noise in Crieff, Scotland” it clearly shows three traces;
1) Mainnet
2) Ascom
3) Measured local background
The traces show massive amounts of interference.

The slide is not ambiguous it is totally clear – SSE is operating a system that pollutes the shortwave. Trevor Clarkson is a very accomplished Engineer and to “rubbish” his presentation this way is a total and utter disgrace.

“The full RA report is available on the web and the RA has also recently confirmed that despite the levels outlined in these reports no interference cases have arisen from the trials in Scotland.”

And what about the interference documented in the BBC report?
http://www.bbc.co.uk/rd/pubs/whp/whp067.html

Extracts from the BBC report;
The degree of interference to reception varied somewhat with location, between "annoying," and a level sufficient to make the broadcast completely unintelligible. The latter was certainly the case just beyond the nearby premises where a repeater was known to be situated (item 15) but some other locations were almost as bad, although the reason why these were worse than others was not always immediately apparent. Some correlation was noted with the underground run of the main distributor cable. Curiously the location near to the sub station was not the worst although badly affected.

Both systems caused interference to HF reception, although one system appeared to have made some attempts to limit this. Some suggestions are made how co-existence between PLT and home radio reception might be investigated; such investigation would be essential before any wide-scale implementation of PLT.

In conclusion, it is totally clear that PLC has a major interference problem that SSE is continuing to deny in the face of massive amounts of clear and overwhelming evidence.

The competent authorities should move to shut these systems down until SSE can prove beyond any doubt that they can operate PLC systems without generating interference.
 
It has been clearly stated by SSE & the RA that the PLC has not caused any cases of interference.

Where is the RA statement?

The SSE statement is in clear contradiction of the BBC report which totally destroys any credibility that SSE had.

I think it is you that lack credibility. SSE have given a fair & honest review of the PLC trials. All we get from you is so called claims of massive interference for which you have been unable to produce even one substantiated case.
 
Quote from my other post.

"Just because they heard something on the tested frequencies does not mean it would interfer with a normal household, ie the tested frequencies are not used for broadcasting of normal radio or TV so it doesn't matter as a normal user would not hear it as they would not have equipment tuned into these frequencies. They even stated that even they could not detect any broadcasts on these frequencies so there is nothing to interfere with."

I can only summise you are one of these Short Wave enthusiasts who potentially will have to move your equipment a few meters at most, well welcome to the real world and the market ecomony. If that is the only inconvenience then the Govt and the Eu will allow this technology. It's about time you stopped your ill informed comments that blow these small interference issue out of all proportion.

This joke has an interesting anology to your argument:

A couple goes on vacation to a fishing resort in northern Minnesota. The husband likes to fish at the crack of dawn. The wife likes to read. One morning the husband returns after several hours of fishing and decides to take a nap. Although not familiar with the lake, the wife decides to take the boat out. She motors out a short distance, anchors, and continues to read her book.

Along comes a law enforcement officer in his boat. He pulls up alongside the woman and says, "Good morning Ma'am. What are you doing?"

"Reading a book," she replies, (thinking "isn't it obvious?")

"You're in a restricted fishing area," he informs her.

"I'm sorry officer, but I'm not fishing, I'm reading."

"Yes, but you have all the equipment. I'll have to take you in and write you up."

"If you do that, I'll have to charge you with sexual assault," says the woman.

"But I haven't even touched you," says the officer.

"That's true, but you have all the equipment.

The Officer says, "Have a nice day."

The BBC interference reports are totally clear.

When are you going to listen, the interference is on frequencies where there was no broardcasts and unlikely to be any unless in a non-english language. How is anyone going to be annoyed by noise on a radio between frequencies on a range where there are no english speaking programmes. Just read the same PDF file you are taking your selective quotes from.

Powerline here we come.
