Fldigi - foldynl/QLog GitHub Wiki
QLog can save log records sent by fldigi. To use fldigi's logbook server connection, select Logbook → Connect to server in fldigi.
Alternatively, fldigi 4.2.6 and later can send ADIF records directly to QLog over UDP. See the fldigi configuration below.
The QLog listening port can be changed under Settings → Network → FLDigi.
QLog also supports using fldigi as a CW keyer. More information is available in Initial Setup.
