|
|
|
|
Select the *Audio* tab to configure your sound system.
|
|
|
|
- _Soundcard_: Select the audio devices to be used for *Input* and
|
|
*Output*. Usually the *Mono* settings will suffice, but in special
|
|
cases you can choose *Left*, *Right*, or *Both* stereo channels.
|
|
|
|
IMPORTANT: If you select the audio output device that is also your
|
|
computer's default audio device, be sure to turn off all system sounds
|
|
to prevent transmitting them over the air.
|
|
|
|
IMPORTANT: Be sure that your audio device is configured to sample at
|
|
48000 Hz, 16 bits.
|
|
|
|
IMPORTANT: Windows Vista and later may configure audio devices using
|
|
the Texas Instruments PCM2900 series CODEC for microphone input rather
|
|
line input. (This chip is used in many radios with built-in USB
|
|
CODECs, as well as various other audio interfaces.) If you are using
|
|
such a device, be sure to set the mic level in the Recording Device
|
|
Properties to 0 dB.
|
|
|
|
- _Save Directory_: _WSJT-X_ can save its received audio sequences as
|
|
+.wav+ files. A default directory for these files is provided; you
|
|
can select another location if desired.
|
|
|
|
- _AzEl Directory_: A file named +azel.dat+ will appear in the
|
|
specified directory. The file contains information usable by another
|
|
program for automatic tracking of the Sun or Moon, as well as
|
|
calculated Doppler shift for the specified EME path. The file is
|
|
updated once per second.
