Dear WSJT-X Devels, I just upgraded my WSJT-X version up to the 2.3.0-rc1; But unfortunately the band hopping seems to be defective; Is this a known issue ? Rig : FT-991 (Yaesu) Windows 10 pro Beelink computer. Cat is working well but Band hopping does not , and WSJT-X doesn’t display night / day / sunrise / sunset.
