Baud rates on the radio and VarAC (or any program the connects via CAT for Freq and PTT) must match, usually the faster the better.
For any Digital mode if your radio has a dedicated Digi Mode (D-U, Digi-U, Digi-USB, etc) them you really should use that as it should disable detrimental features for digital modes such as Compression, NR, etc.
