What I did this summer ...

Ham radio without talking.

The above screen is what it is all about. 


The Digi-Link HAT with the Pi, showing the 12V power supply cable and the Fe-Pi Sound Card

Suzanne did the soldering to build the digi-link and assembled it with the Pi.

The connections are:

The Kenwood VHF/UHF Radio - graciously lent to me by kc9ad

The Yagi Antenna and the 1/2 Wave vertical with Ground _Plane_ Radials

The Yagi is connected to the Kenwood and the digi-link
