Hi
I want to try some long range tests with my RAK811 node. Does anyone have some tips for How to proceed with this? Maybe what configurations to apply to the node? Should I set my join/Rex windows to anything special?
Thanks in advance 
If you do, how will you change the Join setting on the TTS?
How would changing those have an impact on the range - it’s all about uplinks isn’t it?
I am not sure, that is why I’m asking
How will you learn if you just ask questions and do no research?
How will you evaluate the answers for accuracy or credibility?
What do you mean by long range? What do you mean by optimal? How reliable does it need to be?
First principles, what are the Join & Tx1 delays for?
The longest range you can achieve with SF7/125kHz, 14dBm ERP is abt. 300 km. With SF12/125kHz it is more than 1000 km. (Semtech)
You can calculate the theoretical distance by using the datasheet from Semtech.
The practical distance can differ strongly accorting to the environmental conditions.
Have fun while making your experiments!
PS: And don’t forget - the earth is round.
