http://www.levinecentral.com/ham/grid_square.php has been updated to add in the ability to specify a 4 or 6 character grid locator and show it on the map (Thanks K2DBK for the suggestion).

I also added in the ability to clear the form and if a call sign is entered it links to the QRZ page for that call.

The specifics of the page are in the last post – New and improved Maidenhead Grid Square Locator
