Good morning...
You probably already know this but for those who do not... Here is the rest of the story:
While flying from San Diego to Spanish Fork Utah in the AG915 Dave Bacon and others were following us using Radar24 ADS-B "IN"display.
He called me several times along the route asking if our ADS-B was working because he can only see us part of the time.
I assured him it was at least when we fly through or land at airports with equipment to read ADS-B and the device is displaying lat/long as usual.
I told him that honestly, I have not researched how ADS-B works.
However each time you call me, Dave, and ask I've been flying lower than the radar can see while climbing over mountains in elsewhere areas.
The symptoms appear to me if a radar does ping not confirm ADS-B equipment it will not display ADS-B "IN".
He asked me but it uses satellites? Maybe it is only to display the "IN"s on the network if a radar confirms it? That's all I've got that match the symptoms.
Then Dave and I flew to Borrego over the mountains and descended down to the desert at about sea level to land.
On the way back Dave check Radar24 and we were not on the map.
We had others in the desert landing at local desert airports announcing in the pattern and I asked Dave can he see any aircraft in the desert that we are hearing there now?
"No" none of us showed up that was down low = under the radar! But aircraft over the altitude of the mountains were being displayed.
That confirmed my theory.
When we landed back at Gillespie and refueled Dave walked over to the avionics repair shop (1st hangar next to the gas dock) and asked why we did not show up on Raday 24.
He confirmed that if a radar in the system does not ping you.
You will not be displayed nor will any other aircraft in your area be seen by you or anyone else.
I'll keep my normal scan for traffic, thank you very much for a false sense of security watching a new screen... part of the time and not the sky.
