About the QRZ Logbook

The QRZ Logbook System is a master collection of QSO records from all participating members.  Each member may create and populate one or more logbooks for their personal or club use.  The cloud-based QRZ Master Logbook contains over 300,000 logbooks from individual hams worldwide.  Users of the QRZ Logbook enjoy a 40%+ confirmation rate on their QSOs.  On a typical day, as many as 200,000 new QSOs arrive, and around 88,000 new confirmations are produced.  

The QRZ system is continually searching the database for matches.   A match is declared when two separate records in the database match these key details:

• Call Signs - both QSO reports must name the same two call signs
• Date/Time (UTC) - both QSO reports must have the same timestamp, +- 30 minutes
• Band - both QSO reports report the same band in use
• Mode - both QSO reports report the same mode in use

Of course, there are a lot of additional fields in a QSO report, but these are the key values for QSO matching.

The QRZ Logbook is a double-blind system.  This means that both QSO parties must log the contact separately.  In order for a QSO to be confirmed, both parties must use the QRZ Logbook, and each must input the details of the QSO as they observed them.   One side is never told what the other side has reported.  The system will then decide if both reports match, and if they do, a confirmation is awarded.

As you build up a list of confirmations in your Logbook, you earn credit towards QRZ Operating Awards.  You may apply for awards directly within the Logbook, as it contains a full-featured awards analyzer subsystem.

While the QRZ Logbook is available free of charge to all hams, some additional features may require a subscription. In particular, subscribers enjoy the ability to interface their PC logging programs directly with the QRZ Logbook so that their online logs can be updated on-the-fly with modern software.  Subscribers also enjoy an automatic connection to the ARRL's Logbook of the World and the ability to export ADIF log files to other programs and collections.  Subscribers may also name "guest" users who may input records into their logbook.  This becomes especially handy for club or multi-operator operations.

Every logbook has a settings profile that the user may modify to suit the needs of the current activity in order to pre-fill those QSO record details that the user wishes to continue in series.  For example, information pertinent to a particular location or contest, etc.  A mobile user might, for example, update his Logbook Properties Settings each time he moves to a new location.
