CLUSTER RADIO-AMATEUR-OPERATORS · 25 ENTRIES · EARLIEST ENTRY 2021-03-24
Amateur radio logging and contesting tools
This cluster consists of logging, contest, and companion applications for amateur radio operators, including desktop and web logbooks, repeater and callsign lookup tools, APRS monitors, and audio recorders. The dated entry history shows sporadic appearances from February 2015 through late 2025, then a concentration of nine entries in the first half of 2026 (January to July). Traction leaders are QSO Again, xlog2, and cqops-bin, each with 0 stars.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 20 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
