Hi, Yesterday my local flying club held a midnight fly-in. At this even we had 1 Phantom_4 (mine), 1 Phantom_3 and a Blade Chroma 4K and numerous other aircraft. We (quads) all were in the air at the same time and filming various aspects of the event. During startup I got a radio frequency interference alert or caution, when I checked my frequencies I did see a lot of red spikes that went up and down. I do not at this time have the 32 channel hack. I'm running the iPad pro 9.7 as my device. Also several other planes were in the air and we were filming various aspects of their flight. Once I was up and clear of the Phantom_3 the alert went away but I did have several video transmission breaks during the flight. I have flown at this location many times and have only encountered this "radio frequency interference" issue once before when another P3_Advance was flying. I've flown with the Chroma pilot before and not encountered the issue. I've seen videos and read discussions of others flying with P3 and P4. So has anyone had this before and is there a explanation or fix?
