F6FVY has an excellent website that uses Google maps and a simple interface to find your locator / grid square. You just use the controls to zoom in to where you live...click on your house...and up pops your locator square. There is also a box at the bottom of the page where you can input the locator details and it will show up on the map. It's simple to use and shows exactly what the size of the square is.
An excellent site for anyone with an interest in VHF..........or 10 metre beacons ;o)
