### TQSL Utility

The TQSL utility program is used to prepare files for the TrustedQSL system.

TQSL requires an input log file in either ADIF or Cabrillo format. Many logging programs can export log data in one or the other of these formats. TQSL also provides a rudimentary QSO data editor that can be used to create small ADIF files. See Managing QSO Data.

Along with the QSO data in the log file, TQSL needs to know your station location. TQSL provides a mechanism to describe one or more station locations and save them for association with log files. (Even if information is present in the log file that describes your station location, it isn't used by TQSL.) See Managing Station Locations.

Once you have prepared a log file and specified the station location, you are ready to sign the data, which produces a TrustedQSL file containing the digitally signed records, ready to be sent to their destination, such as ARRL's Logbook of the World system. See Preparing TrustedQSL Files (Signing).

TQSL has several configuration options you can set. See Preferences.
