 QRA64 is an experimental mode in the Version 1.7 alpha release of
 _WSJT-X_.  In most ways you will find operation of QRA64 similar to
 JT65.  The following screen shot shows an example of a QRA64C

+transmission from DL7YC recorded at G3WDG over the EME path at 24 GHz,
+at a time when Doppler spread on the path was 78 Hz.  The red curve
 with a peak at 967 Hz shows that the decoder has detected its
 synchronizing symbols, and the decode is successful.
