We have our own avionics receiver on the ranch, not just the subscription service, @ the helicopter was NOT transmitting any data when it was flying over the ranch.

Where is your antenna? What type is it? I also my own "avionics receiver" (ADS-B). FR24 gets far more planes than I see, because of topology.

I believe our antenna is next to the heliport, not sure about type. The helicopter was right there - immediate vicinity. Direct line of sight.

Well, given that they were perfectly visible, I think that the simples explanation is that your ADS-B receiver wasn't handling that particular situation. There's no stealth if you can see it and read the number. Surely someone took a photo with a zoom lens?

I believe the team was truly unable to identify any number on the helicopter, & the avionics receiver was working perfectly fine, from what I was told. You state authoritatively that it was for a power line survey, but you haven’t verified who it really was & if that was the case

Also, maybe you can ask Apple what would cause an iPhone to go nuts as demonstrated on their footage. That should be a major security/usability concern for them.
