I do Whish BaldEagle & you had made a 300 page manual on how to Interpret the HG612stats graphs
Our
Analytical Eagle has essentially developed such a guide from first principles, whilst instructing
Plusnet and using (what was) his defective VDSL2 service as an example!
EDIT checked the multiband scanner and getting a radio station on 7280 Khz AM (7.280 Mhz) it driffs in strong to 8 bars signal strength then driffs off to 0 and comes back again over 3 minutes
It won't be any use for such a higher frequency as 7.280 MHz but here is the
link to the site that shows all LF & MF broadcast transmitters in the UK. That frequency band is
used here and
here, for example, on the North American continent but I don't think those signals are troubling you.
An example of QLN graph analysis.I am currently using a
Huawei HG622 in ADSL2 mode. Hence tones 0 to 255 can be examined. Here is the raw data --

and the graph of that data is attached below.
There is a nasty looking peak between tone 45 - 47, so lets take a closer look. Examining the above raw data, we can see that peak is virtually tone 45 - 46. Performing the calculation --
fmax = ((46 x 4.3125) + 2.15625) kHz = 200 kHzfmin = ((45 x 4.3125) + 2.15625) kHz = 196 kHzThe midpoint of those two frequencies is thus
198 kHz . . . and I don't need any look-up table to tell me that it is
BBC Radio 4, broadcasting on long wave, from the
Droitwich transmitting station.
