However I think the problem is basically because you are (I assume) using LSB for phone, whereas USB is used by the K3 for data. So I think you need to use the option in MixW that says default digi mode is RTTYR (i.e. reverse sideband.) That will make data use LSB. (Not knowing anything about MT-63 I don't know if that is OK - some modes work on either sideband others don't.)
MixW will display a different frequency in data mode, because it shows the frequency of the actual data transmission (i.e. carrier + audio offset) not simply the frequency of the suppressed carrier, as it does in SSB. But it will not actually change the transceiver frequency switching from LSB to RTTYR. ----- Julian, G4ILO.
