PC SOUND DEVICE CONFIGURATION
At this point the selection of your PC Sound Device is required, do so by clicking on “PCSDM” (PC
Sound Device Modem) button on the Common panel, and the “PC Sound Device Setup” dialog
as seen below will open.
This dialog supports the selection of the PC Sound Device to be used as the modem for the
software. The device selected should be a sound device dedicated to radio communications and
not the system default sound device.
At first use either “Default Device” or perhaps nothing will be displayed for the Input and or
Output devices. In either case, this indicates the default system sound device will be used, which
we do not want. All sound devices displayed can be selected as the PCSDM by one of two
means, by “Number” or by “Name”. Where by “Name” is the default, to select by Number the
“By Number/By Name” check box must by checked, which would be the case if upon returning
to this dialog or on restart, the selected device as reverted to “Default Device”. The same device
should be used for both the Input and the Output device normally.
NOTE: Under Windows Vista and later the sound card inputs are only detected when a cable or
microphone is plugged in.
