Radio amateurs carry on the tradition of using a QSL card as a confirmation of a contact with another amateur radio station. A QSL card contains some basic information – the station’s callsign, location, licensee’s name and postal address and often details about the equipment (e.g. transmitter, power, antennas,…). It also includes details of the contact, the date, the time (usually in GMT), the radio frequency, the mode of transmission used and a signal report. Sometimes the QSL card shows a picture of the radio amateur’s shack or home town.
I confirm every initial QSO with my QSL-card via the QSL-bureau. In addition, my log is uploaded to the “logbook of the world” (LOTW). The LOTW is a repository of logs, submitted by radio amateurs around the world. A QSL-report and the QSO/QSL statistics diagram shown below are generated daily by a self-developed software.
