"It's baaaaaaaaaack!"
Well, something is.
On Monday 18th I found the apparent cause of my high error seconds count and repeated disconnections during the evening - the Dell PSU which was radiating a lot of RF noise, detectable all over the house and in the shed, as already documented at length, above..
Since then I've had that computer disconnected from the mains, then I replaced the PSU. All has been well, no more disconnects, error seconds lower if not perfect. No problems with web pages not loading.
Then about an hour ago, web pages weren't loading. Modem still in synch. Logged in to modem and saw the error seconds climbing as I watched, then the modem lost synch.
Put the AM radio on, and heard this around 612kHz :
http://sheddyian.hopto.org/interference3.mp3That wasn't there the other day!
It's not the original interference I heard, which sounded like this
http://sheddyian.hopto.org/interference1.mp3And after I'd isolated the PC causing that noise, the same frequency sounded like this
http://sheddyian.hopto.org/interference2.mp3Which proves that noise wasn't there a few days ago.
I can hear it at varying levels from 522kHz up to 700+ kHz, peak seems to be just under 612Khz.
This time, switching off all computers, central heating, CFLs, TVs etc doesn't silence it. And unlike last time, I can detect it in the garden, and a little way up and down the road. At the very back of the garden it seems to be fading away.
Not sure what to do now. I lost synch, and resynched around 2 meg lower than expected.
This is different interference to before, and isn't coming from the PC that caused the original noise.
Did it cause my loss of synch? Is it causing my drop in synch speed?
I've had 6 days of trouble-free connection, but haven't listened to 612kHz for about 5 days, so can't be sure when the noise actually appeared. Naturally I'm assuming the noise has just started, and that's why I just lost synch but I can't know that for certain.
Thoughts?
