Thanks. I’ve been playing around with adjusting the gain for the last couple of days. I seem to have reduced the range of my receiver by reducing the gain. A few hours ago, I set the gain back to the maximum (-10) and I installed Graphs1090. For the last couple of hours, it seems that my percentage of messages > -3dBFS is around 5%. I’ll check it after 24 hours.
My message rate seems low. I imagine the rate will increase when I move the antenna outside. But how can I tell if I need to add in filters or amplifiers to my setup?
