Thank you Dave for your reply. I'm already testing the implementation of BS + FA in RUMLog with FTdx10, and I haven't noticed any problems. Maybe in recent firmware versions this problem does not exist anymore. On the other hand I'm not a heavy user of dual VFO mode. I'll put my attention on VFO-B.
Anyway, Approach with BS is native for Yeasu TRX and gives better experience for software users. Also, if BS is currently being used in the DXLabSuiteCommander for FT-991, the WSJT-X issue I described should exist there as well. śr., 25 sty 2023 o 00:18 Dave AA6YQ <aa...@ambersoft.com> napisał(a): > > + AA6YQ comments below > > I think there is an issue with DXLab Suite Commander integration (radio > settings).
