When you expand the Signal Strength graph to full screen there is a horizontal red line near the top. What is that representing? Thanks https://www.dropbox.com/s/cqifr9vh4skpig8/Grafana_Signal_Strength_1.bmp?dl=0
It's just -3 dB , which was the supposed 'max' signal to shoot for using gain .. this thought process may have changed in recent years
