Doing some experiment on my testing gateway I have put new pigtail on. I like to leave the SMA connector little loose, as it sits on table and is able to lay down completely when I move it. Staring gateway up, I was not able get response from nodes located further away. And I started to check if automated power level feature implemented in RFM69 library is working properly. ... It ended up that I have added new sensor type in gateway as well as the example sketches for radio nodes called TX Power. It shows the current TX power setting out if possible 32 levels present in RFM69 chips, and translate them into 3-100% float value transmitted to gateway. I did not put 0-100% as 0% made me little worried :) Bellow is picture presenting data from my testing meteo node, now with TX Power level.
