KX3Mate

This is a small controller for the Elecraft KX3.

This is a beta version.

KX3Mate is an application for controlling the Elecraft KX3, a US amateur radio transceiver. To use it, connect the KXUSB included with the KX3 to an Android device that supports USB On-To-Go (USB OTG) via an OTG USB cable and launch KX3Mate.

The KX3Mate and KX3 enable easy CW and RTTY/PSK operation, and in digital mode, decoded data can be displayed and logged. Pre-edited messages for each mode can be sent with a single touch. There are also macro buttons that can be freely configured, as well as buttons with pre-set macros for functions requiring multiple actions, which can be recalled with a single touch. Numerous button visibility settings, including button presets, are customizable.
