Web Noise Plots

Using this link:

https://wspr.live/gui/d/ereVvgn7z/station-noise-stats?orgId=1&refresh=1m

the ONLY noise plots I can see are from KFS.  No other station, including mine, has any data.  Am I missing something?

Thanks for the help.

The reporter names are case sensitive.  Try 'KFS' or 'OE9GHV' to see noise plots from other reporters.
If your config file has:

SIGNAL_LEVEL_UPLOAD="noise"
IGNAL_LEVEL_UPLOAD_ID="YOUR_CALL"

Then YOUR_CALL should appear in the 'site' list.

Thank you for your response, I am testing my system now. 

The notes in the wsprdaemon.conf file only mention SIGNAL_LEVEL_UPLOAD="yes"  

I can find no mention in the help file or the conf file notes of a "noise" option.  Is there other documentation somewhere?

WD 3.0 includes a template .conf file with comments about that variable:

#SIGNAL_LEVEL_UPLOAD="proxy"        ### If this variable is defined and not "no", AND SIGNAL_LEVEL_UPLOAD_ID is defined, then upload signal levels to the wsprdaemon cloud database
                                   ### SIGNAL_LEVEL_UPLOAD_MODE="no"    => (Default) Upload spots directly to wsprnet.org
                                   ### SIGNAL_LEVEL_UPLOAD_MODE="noise" => Upload extended spots and noise data.  Upload spots directly to wsprnet.org
                                   ### SIGNAL_LEVEL_UPLOAD_MODE="proxy" => In addition to "noise", don't upload to wsprnet.org from this server.  Regenerate and upload spots to wsprnet.org on the wsprdaemon.org server

Why do the colors of the lines change? The lines from my three receivers change, it seems to vary based on the noise level.

There are two noise level measurement techniques reported by wsprdaemon:

In Red is the RMS noise level for the whole WSPR band taken from the 0-1 seconds and 110-120 seconds of each 2 minute WSPR cycle when all transmitters are supposed to be quiet.  However this measurement can be disturbed by the presence of an RF carrier (e.g. CW station) which persists through those measurement windows.

In Blus is a FFT noise level which is derived from the quietest 4 Hz channels of the WSPR band.  This measurement looks at the whole 2 minutes of the WSPR cycle, so it averages the noise over a much longer period but may be perturbed by transient noise events like thunderstorms.

In general the FFT measurements seem more useful and frequently show slightly lower noise levels, but we chart them both.

Gywn and Clint have written about this noise subject and you can find links to their documents at http://wsprdaemon.org/technical.html

The noise level measurement database we are building seems to be unique in the radio research world and we have started some efforts to exploit it for new insights into the ionosphere.

The link you gave is to wspr.live, which is written and maintained by Arne.
He takes the wsprdaemon noise data and provides these plots in Grafana.
Your queries are best answered by him.

If I have the right Dean Shutt, AL7CR, your noise plots on the wsprdaemon.org site are all showing at:
http://wsprdaemon.org/graphs/AL7CR/ 

Steve - the color changes are a feature of Arne's code in Grafana. Rob's note on blue and red being fixed only refers to the plots
at http://wsprdaemon.org/graphs/index.html and  http://wsprdaemon.org/graphs/yourcallsign

Hello,
I am not sure what you mean with changing colors but I did a small change to the Station Noise Stats page to make the colors there more "stable". Hope that resolves your issue.

Regards
Arne
