Configuring TQSL

This tab provides control over several settings that govern TQSL's operation:

Prompt for QSO Date Range
This checkbox determines whether TQSL will display the QSO Date Range dialog when Submitting a Log File to LoTW via the Internet or when Submitting a Log File from a Computer without Internet Access.

The QSO Date Range dialog can be used to prevent QSOs already submitted to LoTW that haven't been subsequently modified from being submitted again, sparing LoTW from processing QSOs that have already been processed.

Specify ADIF and Cabrillo File Extensions
Because there are no standard file extensions (.XXX) consistently used for ADIF AND Cabrillo files, TQSL lets you specify the extensions used on your system for each file types. The Select File to Sign and Upload and Select File to Sign and Save dialogs set their Files of type selectors based on the extensions specified on this tab:

In the example shown above, files whose names end in .log or .cab will be treated as Cabrillo files, while those with names ending in .adi or .ADI are ADIF files. When using an operating system like Windows that doesn't distinguish case in file names, the two ADIF entries shown in this example would be unneccessary.

Allow Nonamateur Callsigns
The Allow nonamateur call signs checkbox lets you to choose whether TQSL should treat a nonamateur call-worked as an error. LoTW does not accept nonamateur callsigns, so this option is disabled by default.
