I’ve been asked a few times, how do you enable manual gain within CubicSDR?
It’s actually vary simple, by default CubicSDR has AGC or Automatic Gain Control enabled. This can be helpful however you may see a need to increase or decrease your gain when looking at a specific signal. It can be vary frustrating trying to fine tune something in for a decode when you are not able to control these gain values.
As long are you are using an up to date version of CubicSDR all you have to do is turn automatic gain control off and this will enable manual gain control giving you a slider on the upper left corner of your screen. To do so simply goto:
Settings > Automatic Gain
Once you’ve clicked this you should see the check mark has been removed and your gain slider has been enabled.
