    Nice tool. Just installed it and I just learned that I am in JO52BJ59WH.

    Remark: You don't need cell service for this, only GPS.

    Be aware that once you are past 8 characters you are in the range where the Maidenhead locator is not officially defined, and where you have to worry about the reference datum you are using (the latitude and longitude for a specific location depend on things like the approximation of the shape of the earth used)

    Just being silly/pedantic. Enjoy!

    And if you are working at frequencies where your 10 character grid locator is important, do tell us about it!

    I have a couple Garmin GPS receivers that display Maidenhead grid squares.

    All the times I've used the 10 digits from hamgps while roving and pulled up the grid using it was spot on with where I was parked!

    Yes -- my 20-year old Garmin GPS12 displays maidenhead grids.

    GPS is rather amazing.

    In an episode of California's Gold (old PBS program by Huell Howser, now unfortunately SK) he went to all the "corners" of California where the state borders on Oregon, Nevada, Arizona and Mexico to see what the borders really looked like. He went by the survey markers on the ground, planted by the government agency that planted all these mostly 75+ years ago.

    Then he brought along a real modern-day surveyor with GPS to find that every one of the markers was in the wrong place.:p The CA/NV border that's almost due east of the state Capitol (Sacramento) is in Lake Tahoe, but there is (or was) a buoy marker even there. It was also in the wrong place.:)
