I’ve always been drawn to these more security conscious digital kit, mainly because of the obsession on minimizing any correlated noise or any noise.
Your report makes me very tempted to revisit the AP side of my chain. I had a small but unambiguous improvement with a 902 on 3.3V running OpenWRT as my AP, but I have a relatively clean 2.4GHz environment. Love how you approached tuning things to eliminate the problems in your environment
