In most countries radio amateurs have to keep a log on their transmissions. My electronic logbook contains all connections (so called “QSOs”) I have made on the shortwave bands.

Enter a callsign in the form below and find out, if I had a QSO with that station. The electronic logbook accepts complete callsigns only, no wildcards.

Remark: QSOs on VHF/UHF/SHF are not included in the logbook.
