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 in configured to sample at

- _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

calculated Doppler shift for the specified EME path.  The file is
