AirSpy Mini/R2¶

The AirSpy Mini/R2 requires careful gain configuration as described here. As outlined in that reference there are three different gain modes: linearity, sensitivity and so-called free. These can be set via the -gmswitch when using the AirSpy.
We can activate 'linearity' mode with gain 10using the following AIS-catcher command line:
AIS-catcher -gm linearity 10
AIS-catcher -gm lna AUTO vga 12 mixer 12
On the command line, setting names and boolean-ish values are not case-sensitive (e.g. LINEARITY 10 equals linearity 10). In JSON configuration, keys are case-sensitive and must be lowercase.
More guidance on setting the gain model and levels can be obtained in the mentioned link.
