ADS-B receiver operational

No hot solder iron required for this project. 
This morning, I have been able to capture aircraft flying above me by receiving their
ADS-B 1090 MHz signal. For this purpose the SDRsharp dongle is used. See my blog article of 7 June. All the "ins" and "outs" of ADS-B (Automatic Dependent Surveillance Broadcast) can be found on the internet. For example here:

I followed the intructions of the "Sterrenwacht Leeuwarden" and installed "RTL1090 beta 3" and "Globestrl" succesfully.

Now I can watch "real-time", without internet connection, the aircraft flying above the
western part of The Netherlands:

RTL1090 Beta3 version 

Globe-S, aircraft trajectories on July 5 abt 14:00 hr local time

On top of my PC on the righthand side you see the small antenna (which is designed for television  DVB-T reception) and the RTLsdr dongle inserted in the upper USB port 

Interesting to see how an ADS-B signal looks like in the frequency domain:
