Android

Since 3.16 there is also Android port of Tucnak available. Currently is in beta state, any feedback will be welcome. Focused on tablets but can be used also on cell phones. Due touch control, not all features must be accessible.

Install

Tucnak is not on Google Play. To install you must allow install of untrusted applications. Then download Tucnak APK package from http://tucnak.nagano.cz/download.php#android and install it manually.

Features not included

• SSB CQ and sound recording
• FFT spectrum display
• Parallel port keying
• Bluetooth devices because of no official support for BT from native code
• Serial ports - maybe with alternative kernel with proper drivers

Limited support

• USB devices (Davac4, Rotar4) - It is compiled but it seems it works only on rooted devices. User must be member of 'usb' group.
• Hamlib - It is compiled but only usable rig type is 'NET rigctl'.
