RadioMail can use your current location to automatically populate the location header in your outgoing messages. This is useful for emergency communications, when a forgotten or erroneous location can cause confusion.

By default, your location isn't shared. If you wish to enable this feature, navigate to Settings and turn on 'Include Location' under Messages. Keep in mind that the lat/lon coordinates, embedded in the email headers, are visible to all recipients, including those on the internet.

When you receive a message, an icon next to the sender's callsign indicates the presence of location data. Tap it to see the sender's position on a map.

• Blue circular icon signifies GPS-sourced data.
• Grey circular icon indicates a manually entered lat/lon coordinates, which may not be exact.
• Square icon represents a grid square-derived location, providing neighborhood-level precision.

You have control over how your location is determined. By default, it's derived from the phone's GPS. To modify this, go to Settings, turn 'Automatic' under Location off, and manually input a grid square if you prefer.

RadioMail can craft special messages that will send your position to the APRS network.
