DVB-T TV dongle as Wideband receiver

A couple of years ago I had good experiencies with a TV stick as broadband receiver: https://www.pi4raz.nl/index.php?option=com_content&task=view&id=3180&Itemid=46

This time I used a Terratec Cinergy Tstick+ running under Windows10 to setup a receiver capable of receiving signals in the range 50...1800 MHz (RTL2832U chip / R820T tuner)

The latest version of SDR#Stable from https://airspy.com/download via https://www.rtl-sdr.com/ was installed. Also zadig24.exe was used to install the proper driver.

The dongle was connected to my discone antenne. I have been able to receive narrowband 2m, 70cm and AM airband transmissions so far. Example of 70 cm signal:

Repeater of Goes, received at 430.075 MHz.
