Tudor Vedeanu has posted a nice video showing the Airspy HF+ and Gqrx running on the Raspberry Pi 3 and using what appears to be a 7 inch touch screen.
Note that in order to get a comfortable layout you can:
- Group the audio dock widget together with the other dock windows
- Hide to toolbar and access the functions from the menu bar
- Enable full screen mode
Tudor has also reduced the FFT size to 8192 points and the FFT rate to 15 Hz, which helps keep the CPU load low.
Download Gqrx for the Raspberry Pi 3 and other ARM v6 boards running Debian Stretch here.
