Announcing RadioMail – The first iOS Winlink client app

Georges, WH6AZ is excited to announce the release of RadioMail, the first Winlink client app for the iPhone. With RadioMail, you can easily send and receive Winlink emails via telnet or pair with modems to exchange emails over the air. Finally operators can now enjoy ultimate mobility to check Winlink emails on the go.

To use RadioMail with your radio, you will need to connect an external TNC interface. You can do this through WiFi or Bluetooth, using a VARA modem or KISS packet modem. Radio control can be setup through rigctld if necessary. Note that RadioMail requires a running version of the VARA modem on a separate computer. For packet mode, the Mobilinkd and Dire Wolf packet modems are supported.

The built-in station directory automatically retrieves available station details and organizes them by proximity based on your current location. You can also add custom stations for peer-to-peer connections (outbound only). The favorites list is where you manage the preferred stations you want to connect to. Favorites stations can quickly be selected by modes and bands when you’re ready to initiate a connection.

The app makes it easy to share images and files. You can access your phone’s camera directly, or attach photos from your photo library. RadioMail automatically optimizes images to reduce the transmission time. When you receive an attachment, you can preview it and add annotations if you like. You can also save attachments to local folders or iCloud, or share them via other apps.

RadioMail can also check for new emails in the background at regular intervals, and notify you when a new message comes in. This way, you won’t miss important emails even when you’re not actively using the app. Additionally, you can use the phone’s internal GPS to automatically provide an accurate location for position reports, which are posted to the Automatic Packet Reporting System (APRS) network.
