Thank you so much for your time and the clues. May I ask why have you chosen LMiC instead of LoraMac? I know that LMiC got available earlier than LoraMac and this is one of the reasons that many...

Hi @davhak, I chose to use LMiC because it was very clear to me how to implement this in my project, also there is a clear discription on how to create the HAL. LoRaMAC-node gave so many files I was...

Remember that with an external preamplifier you close the transmission path. With an output of 200mW, it's even possible that you blow the preamp FET.

Yes of course a preamp will help if you have a long cable run. It will however introduce a little bit of noise to the system, and if it is not perfectly linear it will introduce harmonics. The rule of...
