Logbook of The World (LoTW) is an exciting way for Radio Amateurs to confirm two-way contacts they have made and use the confirmations as credit toward various awards.
Because Logbook of The World uses double blind comparison, users cannot see what other users have uploaded unless there is a matched QSO. All files uploaded to LoTW are electronically signed by verified users. Logbook of The World maintains the integrity of the QSO verification process that has long been the hallmark of ARRL awards.
