The WSJT-X 2.0 software suite has been released, and developer Joe Taylor, K1JT, is urging FT8 and MSK144 users to upgrade to what will become the new standard, because the FT8 and MSK144 protocols have been enhanced in a way that is not backward compatible with older versions of the program. That includes any version 1.9 releases.

“The new protocols become the worldwide standards starting on December 10, 2018, and all users should upgrade to WSJT-X 2.0 by January 1, 2019,” Taylor said on the WSJT-X home page. “After that date, only the new FT8 and MSK144 should be used on the air.”

Users are encouraged to read the new Quick Start Guide for WSJT-X. Gary Hinson, ZL2IFB, has released an FT8 Operating Guide.
