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 since 1976 and is usually updated daily.

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 via repeaters on VHF/UHF/SHF and portable/mobile operations are not included in the logbook.
