Andreas Spiess, HB9BLA, is a well known YouTube personality from Switzerland with over 330 thousand subscribers, over 30 million views, and focused on sensors, microcontrollers,  Raspberry Pi programming, and projects that use  this technology applied to amateur radio.  I found Andreas on YouTube as I am preparing my own QO100 geosynchronous satellite earth station, to allow me to work the Quatar Telecom satellite from Israel.  I know that you will enjoy my QSO with Andreas and perhaps become a fan of his YouTube channel.
