The objective of the ARRL International Grid Chase is simple: Work stations in as many grid squares as possible and upload your log data to ARRL’s Logbook of The World (LoTW). If you are not currently registered with Logbook of The World, this is a good reason to get started. Go to https://lotw.arrl.org/lotw-help/getting-started/. Registration and uploading are free. When registering and setting up your Station Location, be sure your TQSL Station Location includes your Grid Square!
Every new grid square contact confirmed through LoTW counts toward your monthly total, so you have an incentive to start the chase as soon as you ring in the New Year.
