JS8 Call V.1.0. was released today!
JS8Call is an experiment to test the feasibility of a digital mode with the robustness of FT8, combined with a messaging and network protocol layer for weak signal communication on HF, using a keyboard messaging style interface. It is designed to connect amateur radio operators who are operating under weak signal conditions.
JS8 is a mode with the freedom to transmit arbitrary length free-text messages using an adaptive text compression scheme (15-18 wpm average, > 20+ wpm on some messages).
