PS
If g3uiss has a few mins to spare & nothing better to do, it may be interesting to compare those missing tones raw data with bit allocation on the VDSL line to see if it does affect both.
The only tone with 0 bit loading is 328 on the VDSL circuit, so its not common to both. The single noise blip is exactly the same on both circuits. I suspect its just an anomaly.
All that said, ISP said they would reset the profile in an effort to sort it, hoping to avoid a visit (difficult for personal reasons to available for either full AM or PM time slots) .
Result:- DS SNR now at 6.1 US SNR now at 12.6 Interleave on US & DS at 8 delay Inp on US only at 2.
So now I'm worse off than ever. I'm awaiting their next update. Iv'e just turned on uploading to put current stats at
www.west-lodge.com/adsl/index.htm@Kitz is right, no radio stuff in this area (Nearest is HMS site which I think is very LF comms)
Not really worried about that single spike as commented it has little effect.
Thanks for all the input
