RaspberryPi-3

My latest acquisition to the shack is a RaspberryPi-3. A great birthday gift to get! I already owned two RaspberryPi-1’s and one RaspberryPi-2.

As always with good quality keynotes, this one tickles me to anticipate in this WSPR-challenge. But I have to be careful not to have too many things on my agenda. With my daily Morse training this is not a good time for another challenge.

Nonetheless a great keynote and many thanks to Remco. Another item on my bucket list πŸ˜‰
