Why does the city police helicopter disappear

When flying directly over my home? It is ads-b enabled. Do police have the option to turn their ads-b transmitters off???


Try turning down your gain.


It’s quite common for for low flying aircraft to overload the receiver.
If you’re interested in local flights, then as above, turn down you gain.
Personally, I’m happy to trade some local position reports for the long range I’d otherwise have to sacrifice.


Ah, the ADS-B paradox …

Everyone turns the gain up to receive aircraft further and further away, thereby no longer capturing data from aircraft local to themselves.
While one site struggles to pick up faint signals from way over there, someone way over there is struggling to pick up faint signals from all the aircraft right here.
