I was just driving around city with node in my car. I have send at SF11 and tried on SF12 without ADR, and always lost node when outside 115 zone. But now after few days I see nodes with -120 RSSI so everything seems fine now. Thanks.
I am also curious about the fault on the converter-board. I received it yesterday, integrated it into my working setup and noticed the software-reset was not working anymore, i had to reset by hand on the board to get it to work.
Also something got hot so i already stopped using it.
I am interested to know what has to be changed to make it work..
