Today, we have updated the Logbook of The World (LoTW) callsign list. This is a December, 2018 list officially provided by the ARRL. An LoTW indicator currently shows in the listings for US amateur radio operators. We eventually plan to expand it to include Canada (VE) and Australia (VK) and we eventually plan to take automated updates from the ARRL.
This list replaces an unofficial list last updated on REC in 2015.
