1. To work correctly this apps requires an external Realtek RTL2832U Radio Dongle connected on usb port using an OTG cable and the installation of the RTL2832 driver (driver of Martin Marinov to be installed from Play Store).
2. The best performances can be obtained by using an antenna tuned to airband frequencies (118-136MHz).
3. ABR allows you to listen airband frequencies as a conventional airband Radio.
4. For any question, please contact eric. loffler@free.
1. Works with the rtl-sdr.Was built for an old Android version and device didn't workDoesn't tell you that you need an external device for it to workGreat if set behind antenna.Can't really tell you.
2. Simple App, works flawlessly with the NooElec R820T SDR dongle.Excellent little airband listener.
