As of Sept 2014 the three U. S. Antarctic stations, KC4AAA, KC4AAC, and KC4USV, are now using LoTW whenever the operator there sends the QSL Manager an eLog. Some of the older logs may be uploaded as time goes on, but for now only about the last two years of complete logs and some old logs that were logged by the QSL Manager when he was listening in over the years.
