Grid Locator


One of the first things you will notice when you tune the low end of any VHF band is that most QSOs include an exchange of "grid squares." What are grid squares? Well, they're more like rectangles and are just a way of dividing up the surface of the Earth. Grid squares are a shorthand means of describing your general location anywhere on the Earth.

Although probably the most valuable area on this page is the Web Links section, the article, "Lab Notes -- Where Am I?", explains how grid squares came to be and how they are determined. The other article shows you how to convert latitudes and longitudes to grid squares.
