The ZIP file contains all data sources used in scoring the October 13, 2023 running of the HamSCI GSSC competition: ReverseBeacon.net, WSPRnet.org, PSKReporter.info. There is a ZIP file containing each entrant's data as extracted from the WSPRnet data. Further, it contains the participant entries (in an Apple Mac OS Numbers formatted spreadsheet) along with the scoring calculation file (Numbers format). Included is a description of the scoring methodology (Apple Mac OS Pages format) and the shell scripts used to extract the WSPRnet data. The GSSC 2023 Results Writeup.pdf, as published to the HamSCI.org website, summarizes the entire event. Additional ZIP files, eg gssc2023bonusXX.zip, contain emails and attachments (PDF, jpg, etc) submitted by the entrants for bonus points. The purpose of the GSSC competition was to generate ham radio 'spots' (records of 1- and 2-way amateur radio contacts on the shortware bands, aggregated in the form of transmission and reception reports stored in the data sources referenced above). The 'spot' data is intended for use in studies of radio wave propagation via the ionosphere.
