I'm running the latest beta. Distance is around 500 meters. I can drop the TX power another 20dbm and the rssi only goes down a few db. Right now I dropped it to 7dbm and the rssi only dropped to -55. I'd like to get to -65 but I'd have to skew the units and there's so many metal buildings here I'm sure I'd get all kinds of reflections. As it is there's all kinds of stuff in the fresnel zone.
