CLUSTER RADIO-DESKTOP-AMATEUR · 33 ENTRIES · EARLIEST ENTRY 2023-03-08
Amateur radio and SDR software
This cluster comprises amateur radio and software-defined radio (SDR) applications, covering signal decoding, transceiver control, spectrum analysis, and network connectivity. Entries appeared sporadically between November 2014 and June 2026, with the highest monthly count being three in March 2021. The traction leader is skyglow with one star, while paracon and CHIRP have zero 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 13 listed below. Unlabelled means nothing has decided yet — not that the answer is small.
