 === QRA64
 
-QRA64 is an experimental mode in the Version 1.7 alpha release of
-_WSJT-X_.  The mode is designed especially for EME on VHF and higher
-bands; operation is generally 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.  Doppler spread on the path was 78
-Hz, so although the signal is reasonably strong its tones are
-broadened enough to make them hard to see on the waterfall.  The red
-curve shows that the decoder has achieved synchronization with a
-signal at approximately 967 Hz.

 The QRA64 decoder makes no use of a callsign database.  Instead, it
-takes advantage of _a priori_ (already known) information such as the
-one's own callsign and the encoded form of message word `CQ`.  In
-normal usage, as a QSO progresses the available _a priori_ (AP)
-information increases to include the callsign of the station being
-worked and perhaps also his/her 4-digit grid locator.  The decoder
-always begins by attempting to decode the full message using no AP
-information.  If this attempt fails, additional attempts are made
-using available AP information to provide initial hypotheses about the
-message content.  At the end of each iteration the decoder computes
-the extrinsic probability of the most likely value for each of the
-message's 12 six-bit information symbols.  A decode is declared only
-when the total probability for all 12 symbols has converged to an
-unambiguous value very close to 1.

+TIP: In _WSJT-X_ Version 1.7 QRA64 is different from JT65 in that the
+decoder attempts to find and decode only a single signal in the
+receiver passband.  If many signals are present you may be able to
+decode them by double-clicking on the lowest tone of each one in the
+waterfall.  A multi-decoder like those for JT65 and JT9 has not
+yet been written.
