There are times when knowing location is important. For ham radio operators if Winlink Express (WLE) is involved the basic describer of location is the Maidenhead grid square. See boondockecho.com for a very good/friendly explanation.
The “grid square” defines a patch of ground. The square is fully described by six characters, two letters, two numbers, two letters. For example: Four character “CN85” describes a location within about 100 kilometers. Six character “CN85mm” describes a location within about 5 kilometers. That includes our Washington County EOC and Hillsboro Medical Center. The article listed above gives more specifics on location such as how close does a 5 character (or 6 character) GPS location come to your precise location.
When first setting up WLE, at minimum you are required to enter your grid square. Your grid square can be located by accessing web site “Amateur Radio Ham Radio Maidenhead Grid Square Locator Map”.
