Is anyone aware of a proximity alarm for UAV (drone) pilots? There is a need for drone pilots to be aware of nearby flights that might be getting close enough for a possible conflict. The DJI Mavic Air has a stripped ADSB receiver on the drone that gives a “Manned Aircraft Nearby” alert wtihout speed direction or altitude. A small aircraft icon appears on the full screen map. From a youtube review of DJI MAVIC AIR2 Airsense by user Ocram there are attached screens for aircraft alert in FPV (first person view) mode .

There a project called ADSB alarm that runs on a Rpi with SDR and LCD display. The ideal would be something accessible on a smartphone, that already has a battery and good display just set the alarm radius and altitude that you want for an alert. There are solutions for pilots like FLARM and EFB but drone pilots would just need the Traffic Alert for nearby flights. There are helicopters in the area that may fly around at 300 ft.
In the near future, many drones will start producing Remote ID https://www.faa.gov/uas/getting_started/remote_id/drone_pilots/
