North American Overlay Mapping
To view the 'About' window, click 'Tools' > 'About'. The 'About' window will open; it contains information about the North American Overlay Mapper, including Software Version, Overlay Version, Licensee Callsign, and Registered Position of your station.
Your Callsign, Registered Position, and other variables are encoded into the software when you registered it. If you wish to change your Registered Position or Callsign, simply re-register NAOMI online, and a new validation file will be generated, that you should save to your computer as before.
