Enable 1200mW Output On DJI FPV System

Here is a hack to enable 1200mW on your DJI FPV Goggles and Air Unit Output Power. However, please make sure you follow your local regulations regarding radio transmission power and frequency.

By default, the maximum output power of the DJI FPV System is limited to 700mW if you are on FCC mode. With 1200mW you will gain roughly 30% more range, and it gives you better signal penetration. Not bad for an easy software hack, and you don’t have to spend extra on new hardware.

However, it’s unclear how it will affect your hardware in the long term, so do this at your own risk. Many have reported using this hack in the winter and it didn’t get any noticeably hotter than usual, but maybe it requires extra attention in the hot summer.

Before performing this hack, make sure your system is already on FCC mode. If not here is how to change it.

  • Create a .txt file, name it naco_pwr.txt
  • Type pwr_2
  • Save and close
  • Copy naco_pwr.txt to an SD card
  • Put SD card in DJI goggles
  • Power on Goggles and Air Unit

To verify you have done it, in the Goggles’ menu, under Settings => Device, you should be able to select 1200mW. Also, by enabling Power Limit, it will give you some protection against overheat when the Air Unit is sitting on the ground.

  • pwr_1 = 1000mW option
  • pwr_2 = 1200mW and 1000mW option

    Hi
    I am in fcc mode. I created a textfile as you described and put it in my googles. Than I powerd up the googles and than the air unit… nothing changed. I tried it many times…nothing changed.

    I have 8 channels and 700 mw output power.

    Do you have any ideas what I can try to get it work?
