Comparison between an unmodified MH-31 microphone (dynamic mc) at my FT-818 in SSB and a modified (electret capsule)
All data measured using the ELV Energy Master Profi-2 Energy Master Profi-2:
Ich habe die Firmware für die Hamware Tuner um den Yaesu FT-991A erweitert.
In Verbindung mit den Logbuchprogrammen UCXLog und Swisslog folgt der Tuner automatisch der eingestellten Frequenz.
Nähere Infos sind hier zu finden.
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.
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.

This is the way I got PORTAINER running on my DS218+

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.
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":
My current setup to operate ES'hail & QO-100.
Here are some impressions on contest I've participated over the last years ...
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!
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.
