New boy in town - QCX-mini

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.

RF Powermeter - Uploading HMI file

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.

2-tone generator - FA-2-NF etc.

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.

hamware - FT890 Unterstützung

Ich habe die Firmware für die Hamware Tuner um den Yaesu FT890 erweitert.

In Verbindung mit dem Logbuchprogramm UCXLog folgt der Tuner automatisch der eingestellten Frequenz.

Nähere Infos sind hier zu finden.

IoT - Air quality sensor

I found a very interesting air quality sensor board from the Germany company OhmTech on Tindy. One of this magic Bosch Sensortec sensor - the BME680 - is used in conjunction with an STM032F72 microcontroller to give a neat "USB-sensor-stick":

SSTV from ISS during February 2019

Here some pictures of the recent SSTV transmission from ISS. They are received using a cheap SDR stick and the NOAA antenna from WIMO under the roof abt. 7m above ground. Decoding is done using MMSSTV.
