ARRL's Logbook of the World (LoTW) online contact confirmation system now holds more than one billion contact records. According to the ARRL Letter, QSO number 1,000,000,000 was uploaded by the Sahara DX Club, 7X3WPL, for a December 28, 2016 contact with IW1DQS on 20 meter single-sideband. IW1DQS had previously uploaded his log so the entry resulted in a match and confirmed QSO.
LoTW has been serving ARRL members and DX hams
for more than 15 years. Confirmed QSOs on the system may be used for all ARRL
awards as well as CQ's WPX and WAZ awards.
