I tried an RF meter to look at the 2.4 and 5.8 GHz output power from the Spark RC. Under iOS, with DJI GO 4.1.3 and corresponding firmware, I could not find any (significant) difference between the stock app and after applying http://dji.retroroms.info/_media/howto/dji.configs_force_fcc I found an insignificant increase from 1.4 mW to 2.5 mW at 5.8 GHz with the FCC config. But I think this is measurement error. Also note that the measured power is far below 90 mW expected for CE. But that may be simply due to the measurement procedure with an attenuator and I was only interested in seeing a difference after applying the config. I measure (for the stronger SMP output, they are not exactly equal, and for the strongest channel) 20 mW for 2.4 GHz and 2 mW for 5.8 GHz (within error margins). I am in CE territory. Using an OTG cable didn't make any difference for me. This is with a 30 dB attenuator connected (and calibrated for) to a ImmersionRC RF Power Meter. This is sad. What exactly did people do to see a difference for Spark/iOS?
