The KX3 Companion in an app that will let the power use of your Elecraft KX3 HF radio easier and lighter. No need for a PC!
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 inexpensive 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!
The KX3 Companion app also let you record full QSOs and log them to eventually export them to your favourite QSO logging software and/or service.
With the new SWR Meter functionality you can sweep a frequency range and the app shows you a chart with SWR values. You can select from 3 to 13 steps, each step can be from 5 to 500 kHz. The maximum number of steps depend on the screen size and orientation.
NEW FEATURE: Audio Spectrum and Waterfall!
Selecting the “SPECTRUM” tool, the app shows the audio spectrum. For devices allowing that, you can also attach the KX3 Audio OUT to the device Audio IN for a better signal. The spectrum shows the DSP filter center frequency and its bandwidth. By touching the spectrum you can also see the shift and frequency of every single line. You can zoom in and out to have larger spectrum bandwidth.
Selecting the “WATERFALL” tool, you can see how the spectrum evolved over time. It is very useful feature to spot every signal even the weakest ones!
NOW with touch QSY! To center a signal you simply have to touch the waterfall/spectrum, move your finger to center the signal you want to listen/decode, and release. Now the KX3 is perfectly centered with the new signal and you can start decoding and transmitting.

Remember that to connect the Elecraft KX3 to your mobile device you need the serial USB cable coming with the radio and an OTG USB cable adapter. Also make sure that your device is not locked to the use of OTG cables. Some carriers (like Sprint Wireless) may do so. Please check with their customer service.
