DL2SBA - HamRadio and more

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.

QO-100 - new pre-amplifier

My previously used pre-amplifier (the one in front of the final PA) only delivers a gain of abt. 9dB @2.4GHz. This was far too less for my final PA used.

Here are some impressions on contest I've participated over the last years ...

LimeSDR - Housing

To protect the fragile LimeSDR mini PCB I placed the SDR inside an aluminium case.

I received a new WLAN grid antenna from a fellow Ham - thanks for this!

Introduction

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":

JackYack - simple memory morse keyer

My Mosquita got a new housing as described in this post. As you can see, there is still enough room for a memory morse keyer.

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.
