| === QRA64 | ||||
| 
 | ||||
| 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. | ||||
| _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 reasonable strong its tones are | ||||
| broadened enough to make them hardto see on the waterfall.  The red | ||||
| curve shows that the decoder has achieved synchronization with a | ||||
| signal at about 970 Hz. | ||||
