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
- Save and close
naco_pwr.txtto 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.
