@00110010_techboy_00110010 , if you are experimenting with nRF24L01 boards, including the higher power variant you have, then the go-to starting point that you will most likely be directed to is this one from Robin2 (which you previously found):
You've discovered:
radio.setPALevel(RF24_PA_LOW);
to reduce the Tx RF power level. You may still need to separate the radio modules by a few feet as well.
In addition, make sure that you have a good 3.3V supply to the radio module.
Where are you getting the 3.3V from to power the radio modules?
