What is LOTW?
LOTW, or Logbook of the World, is a system operated by the ARRL where users from around the world can submit records of their contacts. When both participants in a QSO submit matching QSO records to LoTW, the result is a QSL that can be used for ARRL award credit. This is because LOTW is tightly controlled to verify submissions. All QSO records are digitally signed using a certificate obtained from ARRL. Obtaining such a certificate requires verification of the licensee’s identity either through mail verification (US) or inspection by ARRL of required documentation (non-US).
