Broadband Speed Test

I presume 200kHz R4 LW is comprehensively trashed (or avoided entirely).

How do you get to see your channel profile in that much detail?

276kHz has zero symbols for everyone, it's the downstream pilot frequency. B-)

Donno what would be knocking out 375KHz, that's not in the MW broadcast band (526kHz to 1606kHz). A google sort of indicates a non-directional beacon but with locations in Iceland or Poland. I don't have any nasty dips until the MW broadcast band starts. Occasionally R4 LW on 198kHz makes a small dip.

Not badly, 7 bits at 198kHz rather than 8 bits for surrounding bins

Easy to get from a Cisco router (though RouterStatsLite will do a similar thing for many other routers).

200 kHz ???...

Ah yes, had forgotten about that, or rather, thought it was somewhere in the "gap" between downstream and upstream ranges, wonder why there isn't a corresponding hole at 69kHz then?

Sorry that was a typo 370.875

Donno I haven't got a dip their either.

Still outside the MW broadcast band but again could be a NDB. Near an airport?

OK 198kHz then.

What's 2kHz between friends?

Actually I would have thought a strong signal at 265kHz would not be a big problem for a broadcast signal close to 200kHz.

It only moved to 198KHz 23 years ago. Give him time to catch up. ;-)

Have you tried a different modem? Many of Cisco's ADSL modems are very poor performers even with the latest firmwares released to get them to perform better with BT's kit.

You can argue with them if you can find someone who cares if you want. They are just a list of facts.

I doubt if Virgin wants everyone adjusting things. Maybe you should do as they want and ask support to adjust them, once you have found out what.
