Synopsis

This tool reads a WSPRnet spot database dump in CSV format from standard input, identifies QSOs by correlating mutual WSPR spots within a four‐minute time window and writes an ADIF log to standard output.

Usage

Example

gunzip -c wsprspots-2021-01.csv.gz | wsprspots DO5EU > wsprspots-2021-01.adi

Generated ADIF log:
