Hi Dani Yes, what you are seeing is normal behaviour and has been so for some time.
Can't answer the question about tone spacing. 73 Charlie G3WDG > Hi all, > > I've been testing the JT4G decoder in WSJT-X 1.9.1 together with Wei > Mingchuan BG2BHC, since this is the mode used by the lunar satellite > DSLWP-B.
