Editorial interest 79/100 Selection signal · not a rating of the site

A free, open-source amateur-radio client for JS8 and JTTY, with a faster 64 WPM mode, mesh relaying, and station-monitoring features.

Landing page captured for the 2026-10-28 issue.

For: Amateur-radio operators using JS8 or JTTY
Worth noticing: Its relay map can build routes through stations already heard, and the page says any JS8 program can relay.

Field notes

The page describes Subspace decoding JTTY signals across the waterfall, while WSJT-X is said to cover only 1200–1800 Hz unless retuned. Its interface labels call signs directly on the waterfall and keeps station conversations in separate windows; a click-by-click guide walks newcomers through a first QSO. The download links name Windows, macOS, Linux, and Raspberry Pi, and the project identifies its license as GPLv3.
