side by side test

Hello
I’m trying to compare airspy r2 with the prostick.
I set up VRS to receive data from the prostick (pi3 unit) and from the locally connected airspy but I’m sure that I’ve done something from. Both receivers are connected to the same antenna using a splitter.
The question is how can I display the entire data set from both receivers simultaneously?
I have the feeling that VRS is not displaying the plane detected by both receivers.

Thanks in advance
Emil

Configure the airspy to provide data on an unused port
-l 33333:beast (listen from connections on TCP port 33333 using beast mode)

The std dongle can be reached on 30005 and 30105.

You will need two devices if you want to see MLAT data separately.

FYI, I have a few airspys. They seem to be deaf without a pre-amp/filter.
