If the ExpertSDR2 and digital modes software run on the same computer, they can be
connected via a virtual audio cable without wires and sound cards.
For each program receiver (RX1, RX2) you can set the virtual audio cable on the corresponding
tab Channel 1 and Channel 2.
Enable - set the Enable checkbox to enable virtual audio cable.
RX - select the output and driver for the audio signal received by the ExpertSDR2, which can be
transferred to the third-party software via VAC.
TX - select the input and driver for the audio signal generated by the third-party software and
transferred to the ExpertSDR2 via VAC, for transmission on the air.

Sample rat e – sampling frequency.

Buf f er – size of the buffer.
·
RX gain – additional signal amplifying in the virtual audio cable's RX path in dB.
·
TX gain – additional signal amplifying in the virtual audio cable's TX path in dB.
Note:
·
Before enabling the VAC, make sure all settings for audio devices are correct.
·
To transmit the signal from VAC, PTT command should come from CAT interface, not by
pressing the MOX button or PTT foot-switch. Thus third-party software controls when
transceiver goes to TX or RX via CAT interface.
·
VAC always operates in 2 channels.
