\"\"<\/a>Many thanks to SWLing Post<\/em> contributor, Jeremy, who–in light of our recent discussions about RFI–shares the following news item from the BBC<\/a>:<\/p>\n

The mystery of why an entire village lost its broadband every morning at 7am was solved when engineers discovered an old television was to blame.<\/strong><\/p>\n

An unnamed householder in Aberhosan, Powys, was unaware the old set would emit a signal which would interfere with the entire village’s broadband.<\/p>\n

After 18 months engineers began an investigation after a cable replacement programme failed to fix the issue.<\/p>\n

The embarrassed householder promised not to use the television again.<\/p>\n

The village now has a stable broadband signal.<\/p>\n

Openreach engineers were baffled by the continuous problem and it wasn’t until they used a monitoring device that they found the fault.<\/p>\n

[…]”Our device picked up a large burst of electrical interference in the village.<\/p>\n

“It turned out that at 7am every morning the occupant would switch on their old TV which would, in turn, knock out broadband for the entire village.”<\/p>\n

The TV was found to be emitting a single high-level impulse noise (SHINE), which causes electrical interference in other devices.<\/p>\n

Mr Jones said the problem has not returned since the fault was identified.[…]<\/p><\/blockquote>\n

Thank you for sharing this, Jeremy. I can guarantee that if the TV was emitting enough noise to interfere with broadband, it likely also affected the HF, MW, and LW radio bands!<\/p>\n

What baffles me is the amount of time it took for the engineers to track down the source in such a small community. A skilled RFI engineer would have likely discovered what was causing the noise by looking at the spectrum analyzer–quite often the signal shape and frequency are indicators. In addition, a little signal “fox hunting” could have proven useful. With that said, noises aren’t always easy to locate and can travel along unexpected paths.<\/p>\n

I certainly don’t blame the resident for remaining anonymous!<\/p>\n","protected":false},"excerpt":{"rendered":"
