Gain of RTLSDR

[kochikame]

Hi,
I would like to know how can I send GAIN commands when we call modeslive --source rtlsdr?
Thanks in advance

The gain setting is automatic, see

pyModeS/pyModeS/extra/rtlreader.py

Line 41 in 7727315

self.sdr.gain = "auto"

Then you may want to send a PR on the modeslive script to take that parameter into account. The script starts in streamer/modeslive.py:main()

Thanks a lot
My intention is create a portable TCAS module using a raspberry pico with a sdr and a gps to calculate the proximity with other planes. It will be good when I am piloting a piper PA28 in my air club.
