Hi Robin ,
I have followed that tutorial every way I can with others. I cant get the pair to work on only channel 76. I have set PA to max and Data Rate to 250KBPS. Using a 2 amp 5 volt wall adaptor to provide power to both the arduino and the power board for the nRF24 radio. Is there anything else I'm missing that would affect distance?
I have also tried all 4 radios and power boards I have
