Having read through the majority of this thread I see lots of reports of improved range yet it is unclear if the mod actually uses previously untapped spectrum. You can't get more cake by slicing it differently. Or is it that the hack taps the spectrum around WiFi channel 14 which wasn't used in the 8 channel unmodded version?
Would love to see a spectrum analysis to confirm assumptions.
The concept is very simple: more channels more probability to have a free frequency (channel) to use. Spectrum analyzer can't explain nothing more than this. Wifi ch 14 is not used in the U.S. so DJI channel above 20 are more suited for p3 control.
