RBN Analytics

Skimmer frequency accuracy

To be a good RBN citizen a skimmer should have a frequency accuracy of 2ppm or better.

To use the data below to improve the accuracy of your skimmer, multiply the current value of FreqCalibration in your skimmer software’s settings file with the suggested adjustment factor listed below.

The location of the settings files are:
CW Skimmer Server: %appdata%\Afreet\Products\SkimSrv\SkimSrv.ini
CW Skimmer: %appdata%\Afreet\Products\CwSkimmer\CwSkimmer.ini

The data listed here is based on archived RBN data from the previous day, UTC time. When making adjustments, this means that changes in calibration will not have full impact on the listed data until the second day after the change.

The deviation estimates listed below are based on spots on all active bands from the respective skimmer. If different hardware is used for different bands, the deviation number may thus not represent the actual deviation for a particular band.

The software used to calculate the tables below can be found here. It runs as a cron job in an Ubuntu container on my server and uploads to this WordPress site ten minutes after midnight UTC every night.

The calculation of deviation estimates is done in two stages. The first stage uses a small number of highly accurate skimmers (called “anchor skimmers” in the code) as reference skimmers. The whole estimation process is then repeated but using the anchor skimmers plus all skimmers with 0.2ppm or less deviation from the anchors as reference skimmers. This way the number of qualifying spots is drastically increased, leading to much more reliable estimates for all skimmers. All skimmers used as reference skimmers in the second stage are marked with an asterisk in the table below.

Due to propagation characteristics and statistical variations some skimmers selected as reference skimmers in the first stage may have more than 0.2ppm deviation in the second stage. This is not an error.

292182 RBN spots between 2020-10-23 00:00 and 23:59 UTC.
68122 spots (23.3%) were from reference skimmers (*).
Average spot flow was 203 per minute from 161 active CW skimmers.

142929 spots from 157 skimmers qualified for analysis by meeting
the following criteria:
 * Mode of spot is CW.
 * Also spotted by a reference skimmer within 1000 spots.
 * Also spotted by a reference skimmer within 30s. 
 * SNR is 3dB or higher. 
 * Frequency is 7000kHz or higher. 
 * Frequency deviation from reference skimmer is 0.5kHz or less.
 * At least 5 spots from same skimmer in data set.

Historical skimmer frequency accuracy

Below you will find historical accuracy data for the past five days. Do not be concerned over minor daily variations. Since RBN spots only have 100Hz frequency accuracy, the input data is very noisy. Even for a perfectly accurate skimmer, the typical RMS rounding error across all shortwave bands is around 3ppm. This means that for a skimmer with 1000 spots per day the statistical variation is up to 0.2ppm. For skimmers with less than 100 spots per day the statistical variation can be above 2ppm. The content of the table below is based on the historical content of the above table.
