Finally, a rag-chew version of FT-8!
The mode JS8 began as a derivative of the WSJT-X group of modes that was restructured to allow message passing using a form of the FT8 mode, modified by Jordan Sherer and was named JS8.
Initially, the s/w program was named FT8Call, and later renamed to JS8Call. In clarification, JS8 is the mode and JS8Call - for JS8 Directed Calling, is the Software program that uses the JS8 digital mode to provide weak signal messaging to Hams.
This program is experimental and still under development. Using open-source code, you can be part of the development and submit your changes to the JS8Call group for potential inclusion in future iterations of the software.
The purpose of the experiment is to test a digital mode with the potency of FT8, along with being messaging capable with a communications protocol for low power comms. It has no other purposes other than connecting hams, operating with low power systems, keyboard to keyboard.
Thus, the primary benefit to ham communications is being able to pass pre-defined messages and rag-chews by directed calling.
