Lack of support from Plusnet

Well over the last 2 days we have gone through sleet, rain, hail and snow and still a silent line so the signs are all good on that side.
Here's the next screenshot, Jack.

[#2]

Also we are under the influence of a low pressure system at the moment, as is Europe, by Saturday we should be under a small ridge of high pressure, but high pressure will not cover Europe until Sunday night. This will all have an effect on propagation over LW & MW, a really good line will see minimal effects.
Have you had a much brighter day this afternoon, has been here, ie darker later, was comparing the spikes on the last plot (1716 & 1749) to yesterday late afternoon. I'm slightly concerned (because of the unknown factor) about the one at 1749 (similar to one yesterday at 2133). DMT saw it as big enough to alter it's scaling (on both occasions). However, one consolation, there was no marked hike in errors.
Also just to backtrack on my comment on 1130/1133 today similar to 1048/1050 yesterday, this could also be someone turning on their broadband, maybe in your building, maybe nearby, just on the same cable - I used to have a very similar thing on a regular basis, but that doesn't seem to have happened of late which is why with brain in low power mode I'd forgotten about it!

Wouldn't the length of wire from the Telegraph pole to your average house be roughly ideal (as an aerial) for picking up the MW band? 

[#4]

As far as I know Chris the only other Broadband in the building is in the next door flat and he's at work all day, so it can't be from there, on one side of the building is open parkland and the otherside is an old folks home, maybe the management have broadband?, when you say on the same cable which cable do you mean?,Jack.

[#5]

Chris,  I think these are the two you arew looking for, I can't see anything that matches but maybe with your one eye you can,Jack.

@ Axis
Not ideal, not really, most will be a lot shorter (ideal for SW   ). Slung between 2 to 4 poles might be nearer a quarter wavelength, depends which stations your interested in ;).
I have used a phone line for ham reception before now  
@ Jack
Local drop /Local DP to Cab or Pillar, depending on density of subscribers upto 20/25 pairs perhaps, beyond that, probably too may pairs in the cable it's just part of the background noise. I'd guess above 25 pair you can forget it, but it will depend on how many services have broadband and how many keep it on 24/7. The more there are on the less of a significance one will be.
Edit: I think that last one is probably best directed at someone working at Martlesham/Adastral Park.

Oh p... (as in bear). I've noticed that on my RS. If you open the graphs in RS the tail end is cut off. Can you open that yesterday .jpg in your browser and have a look for 2133. If it doesn't show anything (highly probable, I got my magnifier out on the other one  ) don't post it.

@Anotherone: When you're looking at the spikes (negative ones) on the DMT graphs of SNR over time, I guess you're looking to see if they're re-sync outages, right?
I think the downtime of a resync causes the UAS field (Unavailable seconds) to start going up - generally showing something in the region of 13s-19s for a single resync.
The UAS value in the DMT screenshots stays at 13, while AS is going up. My read would be that they're not resyncs, but more likely to signify problems for DMT in acquiring the data.
Another question: What is the significance behind the blue-ish band that surround the white SNR line in those graphs? It isn't there all the time, and seems to be a fixed size (in pixels) - the size doesn't change even when the scale of the graph does. Likewise for the occassional feature where a reddish-orange band surrounds the SNR line. These are larger, but only appear sporadically (twice in the lastest graphs).
I was wondering if either correlated to any of the other statistics going up (perhaps RScorr for blue, and CRC for red).

Unfortunately the time limitations on RS and DMT are different and on the RS shots one finishes at 21.09 and the next starts at 21.49 I realised this could happen just hoped it wouldn't, I can't think of anyway to match the two timewise,Jack.

[#10]

Last of the day, Jack.

[#11]

Hi Jack, that's strange. Although I wouldn't be expecting the end-to-end times for DMT & RS to coincide, the RS auto saves should be exactly sequential  (the only snag being what's visible throught the RS viewer), all can be seen opening the jpg's in a browser (you might have to scroll to see the bits you want). I've attached 3 of my graphs settings pages for you to compare/see if anythings different.

Nope, wrong, sorry Mike. Looking for increasing errors! - No change in DS bitrate (also confirmed on RS). Your comments about UAS/AS are right & I looked at all the other figures.
I did comment in reply #166 (I've added bold)

Because of the scaling change, if not sure it's a polling issue. It would be nice to get a handle on these spikes even if there is no significant effect at this time!!

Just looked at the last one, and the previous one which I hadn't earlier -
~1937, ~1942 , ~2058 , ~2112 , ~2123 , ~2239 . Hmmm.
Jack, any idea how much (qualitative, rather than quantitative) traffic might have been going through the router at any of these times eg. gaming, downloading or anything? Bit of a mystery at the moment.
Interesting that the ES errors have only gone up by 3 over each period, CRC's up by 4,5, & 3 over each of the last 3 periods, suggesting all is fine

[#13]

Hi Chris,
                At these times my computer would be very quiet as most of my usage is during the day, as a matter of fact I've just checked my usage and it's very low this month about 50% of my normal usage. Routerstats and DMT would be running but that's about it,
I've reset the time span on routerstats to cover 2 hours, hope it will match DMT now, Jack.

[#14]

First, second, third, and fourth of the day,Jack.

[#15]

Hi Jack,
well looks good, except no.1 of the day didn't seem to be sampling the SNRM for some reason, a rather flat line, I thought - now your line seems improved but it's not THAT good ;D.
Anyway in ~17 hrs CRC's up 21, ES up 14, HEC up 20, RSuncorr up 301 all of which is peanuts, especially considering the traffic. I assume the RS plots didn't show any spikes, just those on DMT as yet unexplained at 1259 & 1442 ?
Sorry didn't have time to reply this morning, bang goes that theory about high traffic then!
