Well, what can I say !


Another 4 Engineers, another 2 plus weekends and a whole new cable and guess what  ...Yep, SNR still at 4 to 6 db.....



Hmmmmm I wonder if its that Hi Fi unit in the corner.   Hang on a minute , I will just unplug the Sony micro system and see what happens..................Oh look ! My SNR is now 34 db............plug the Sony back in..........6 db..............unplug........34 db


Well, all there fancy test equipment said no noise was on the line ?




Hmmmmm my poor little Sony Micro System knocked out two streets and 8 ADSL lines for the past year. YET the flash, expensive Spectral anaylis machines that cost a fortune did not detect AIRBOURN inteferance from a faulty Switch Mode PSU on a micro hi fi system

I have recently heard of another similar case where a TV ( faulty scan coils on the tube of a widescreen ) was knocking out 3 streets in London.


Best test equipment to find this fault is a portable AM radio tuned in to any band.  It will just buzz and block out any radio station if it picks up any airbourne signal that can knock out ADSL.



My Sony is now repaired , it was a faulty 47uf smoothing capacitor from the PSU causing AC ripple to propergate through the airwaves. The whole street is now back online and I am now a local hero  8) ( although when they found out it was my gear I was the local villian for a while  )

Now, I am just a happy bunnie
