8. Introducing AndFlmsg NBEMS app for Android The main objective of this development is to provide a low power highly-portable, as in mobile or backpack, Flmsg/Fldigi solution. Rigs like the Yaesu's FT-817, Icom's 703 and Elecraft's KX3 would be the typical companions of the Android phone or tablet running AndFlmsg, thereby providing a low weight, low energy requirement, access to most Flmsg services. The integration of Internet sharing/forwarding makes this solution attractive as a relay option, possibly a mobile or portable station in a pertinent geographical location. The inclusion of modes like MT-63 and long interleave MFSK modes allows audio coupling to be used effectively without the need for an audio interface. In a more developed configuration, for example with a 10” tablet connected to a Bluetooth or USB keyboard plus mouse, and maybe also with an audio interface, the operation we get, including data input, nears the performance and practicality of a laptop configuration but without the power consumption and cost of the later. Also, the data entry forms can be re-modeled independently of the display forms in order to match the screen real-estate of the target devices.
