I have read the manual but skipped binding since phantoms come factory pre-bound.
@mirrorimage I wonder how much of the controller internals will have changed to add the 2dbi.
@sinsalo I would assume DJI would keep up their FCC relations by complying with regulations. Otherwise why would they lock down the channels in the firmware to begin with?
heres my source

I ran my spectrum analyzer before I installed the channel hack and then afterwards. The hack does not change DJI channels 13 to 20, it just adds more channels above and below the original 8.
The channels are 8 mHz wide with 2mHz spacing. The center frequency of a DJI channel is Fc = 2286 + (channel# -1) *10
the lower frequency is Fl = 2282 + (channel# -1) *10
the upper frequency Fu = 2290 + (channel# -1) *10
E.g DJI channel 7 spans 2342 mHz to 2350 mHz, DJI channel 32 spans 2592 mHz to 2600 mHz
DJI channels 13 to 20 are coincident with the US WiFi channels 1 to 13.
DJI channels 21 to 32 occupy 2482 mHz to 2600 mHz and are above the US WiiFi channels. I assumed that since DJI removed channels 21 to 32 it was because it was illegal to use those frequencies in the US. But now I'm not so sure.
https://transition.fcc.gov/oet/spectrum/table/fcctable.pdf seems to indicate those frequencies are available for ISM use. It'd be good if others could interpret what that document says about those frequencies.
