I have an FM Trap and LNA installed at my antenna and am using a RTL-SDR V3 dongle. I can enable the bias-t in Windows on other software and it works fine and I can see the increased gain from the LNA. So the hardware works.
In SatNogs on my Raspberry Pi B3+ I want to enable the bias-t on the V3 dongle using the rtl_biast program which is done via the following command: /home/pi/rtl_biast/build/src/rtl_biast -b 1
I am assuming this should be done via the pre-observation script - is that the best approach? If so, what is the correct syntax to execute that command?
If not via the pre-observation script, what would be the suggested method to do this? I am a Linux noob so go easy on me.
