Using RSSI isn't very reliable (it's disabled in the code for a reason). We might try hw channel activity detection. Since we are gonna TX anyway it shouldn't be too bad to listen for a few milliseconds first. Worst case we see there is a transmission and we wait a little while. Alternative is that we just TX anyway and intefere with others causing transmission collisions.
Would be great if people could test this on their repeaters & companions and see if TX becomes more reliable.

First impressions after flashing this on one of my repeaters that is high up & exposed to a lot of other repeaters is that it responds a little more consistently. Sometimes it's snappier, but often times it's slightly slower but it fails way less. I.e. less failed status requests & non-answered commands.
