You will need to enter your callsign (AB3TQ or AB3TQ/P etc) into the configuration screen - in place of the (NOCALL) and make sure that each entry in your log is updated to have the correct callsign. If you are editing an existing log without your correct callsign double-click each line select the correct version of your callsign and click the ‘update’ button.
Just go to the Database web site at http://www.sotadata.org.uk/ and select one of the Import options on the Submit Log Menu (depends if you are activating or chasing):
after logging in click the Browse button and go to your SOTA logs folder and select the log you created or edited and click the Upload button.
When the database has accepted your log you can simple close the log in SOTA CSV Editor (Ctrl-F4) and start a new one for the next time (or you want a ADIF version to load into any other logging program then click File -> Export to before closing the log).
