Gang I have been tuning my primary receiver and the last bit is to get it set to the optimal gain for my area. Right now the process is running with Automatic Gain set at the command line and I can see it cycle the gain setting while I monitor my receiver’s stats based on the stat themselves, I can see a message rate of 600/sec go to 300/sec and then change to 400, 500, etc as the system continues to try different gain settings. What I would like to do is lock it in at the peak and I have no way of showing that setting (that I can see).
When I run:
sudo systemctl status dump1090-fa -l

it does not show me the gain in use at this moment, just the -10 in the command line. So with all that said, is there a way for me to show the setting at any given moment?
