I recently stumbled upon a website that lets you type in your grid square locator, then upload your adif version of your ham log, and it produces a world map of all of your contacts. It’s the electronic version of sticking pins on a world map or globe.
Here is what my QSO map looks like currently. You can see I’m still missing a large section of Africa and Asia. Click the map to see a larger version.
Here is the link to the service: http://levinecentral.com/adif2map/
