How to choose between Voice and Data for transmission source ?

Use menu 32 "TX IN" to choose the source of the transmission for LSB, USB, AM and FM modes. Main choices are :
  • Microphone (MIC),
  • USB sound card (USB).

If you have no output on SSB or PSK check this setting.

The other choice is "Auto". With this choice the FDM-DUO switches automatically between MIC and USB settings.

If the operator press the PTT key of the microphone, the FDM-DUO switches to MIC setting and goes to transmission.

If the TX CAT command is sended, the FDM-DUO switches to USB setting and goes to transmission.
