I have a problem with VarAC and FT-991A, when I go to transmit no power comes out, I checked everything and it seems configured well, the radio works in all other digital modes: FT8, Winlink, UISS, ..... Nothing to do with VarAC, I receive regularly and goes in transmission, but without carrier.
If I put D-USB it goes out carrier, but I don't receive, to receive and encode the radio it has to be in normal USB mode, only that in this way it goes to TX, but it doesn't go out carrier, I'm going crazy ...
It makes me think that it is some setting of the radio menus, however, I repeat, in all the other digital modes it is fine, I have the latest versions of everything: program, file cat.ini, ..... Do you have any ideas?
It has to be your 991A menu settings for offset in the Digital modes. It has been covered here a bit with pointers to the menu settings needed. USB-D is the mode the radio should be in.
