It will let you send and receive CW, PSK31 and RTTY by using your mobile phone or tablet keyboard. Optionally you can use an external Bluetooth keyboard connected to your Android device.
You can set up to 10 macros to that can use dynamic symbols to have Call, Name, QTH and Locator automatically updated.
It connects to your KX3 by using the USB Serial cable that comes with the radio. You’ll also need an unexpensive OTG Cable adapter to connect the serial USB to your mobile device. You can find them for a very few dollars. No other cables are needed!
