I’ve participated in contributing real-time FT8, FT4, JS8, WSPR & CW spots from 630m-6m since about 2018 using several different simultaneous multi-band, multi-mode SDR spotting systems. These have been built on various SDR hardware including the Redpitaya, KiwiSDR, RaspSDR and more recently RX-888. SDR software has included CW Skimmer + CWSL + CWSL_Digi, DigiSkimmer, SparkSDR and most recently UberSDR. All of these systems are capable of uploading spot (date/time, call, band, mode, SNR and grid) information to the PSKreporter server for mapping. Behind the scenes though there is a statistics page that ranks top spotters by raw number of decodes overall as well as per band, though I’ve never cared to the interface nor the method of crediting spotters.
I’ve also used and contributed WSPR spots to the WSPRnet.org system which is in turn used by wspr.rocks which itself has a very nice user interface for competing in daily spot reception challenges. With that interface in mind I’ve come up with my own PSKreporter display I’d like to share. Its still in its early stages, but the idea is to provide a PSKreporter Top 50 Spotter Ranking view that more easily visualizes the spotter data much like the wspr.rocks challenge and credits spotters accordingly. You can read about the math behind the rankings if you’re interested.
