Did you know that the receiver pane docks intelligently when the height is greater than width (i.e. docked vertically) as shown below. In this screenshot the Pluto SDR is being used with the QO-100 satellite.
After talking on QO-100 with Mike, G0MJW i've ordered a LibreSDR from AliExpress where it's known as "SDR AD9363 AD9361 ZYNQ7020 ADI Pluto communication experiment platform".
