Last weekend I've finished my QCX-mini kit for 20m from QRPLabs.

This was a birthday present from my wife and she is very happy, that the QCX-mini now works great ;-) I'm too ...

On Sunday I was able to make three contacts to the US south coast - 5w and a dipole - thats fine.

The Nextion display needs the content defined in the file PowerMeter.HMI. You can either upload it with the Nextion editor via a serial link to the display or you can copy the TFT file to an SD card and put this into the socket on the Nextion display.

One of my HAM fellows has build a new 2kW HF amplifier. Together with his SDR ANAN-100 he gets really impressive IM3 values.

This inspires me also to do some measurements on my existing HF transceivers - K3 & KX3. For this I needed a two-tone generator.
