Tap anywhere on the map and app will show you Grid Locator Reference. This is convenient tool for ham radio operators to make a plan for portable and/or mobile operation as well as big DX expedition. Internet connection is required. Zoom in to street level, app will show you 10 digit locator. Note: Usually Grid Locator is 6 digit as defined in ARRL document. This 10 digit is expansion of 6 digit as 7th and 8th are divided by 10 ("0" through "9") then 9th and 10th are divided by 24 ("a" through "x"). This logic is based on article on Wikipedia.
