Logbook of The World^® — LoTW^® — is a web-accessed database and repository that enables you to submit electronic logs for amateur radio contacts (QSOs) and for confirmation (QSLs). Users can view submitted QSOs and resulting QSLs online. Radio amateurs can use LoTW to track their progress toward achievements and awards such as The ARRL Worked All States Award, and amateur radio’s premier award, DXCC^®, membership in which is achieved by confirming on the air contacts with 100 countries.
