I recently “upgraded” from two separate Pi 3B+ devices on Raspberry Pi OS to a single Pi 3B+ using v 4.0 of the PiAware SD card install. I am using the FlightAware blue and orange SDR sticks. I followed the procedure for applying serial numbers to the receivers and modified the piaware-config.
All appears to be working but I am getting considerably less activity. For example I averaged about 400K reports per day with the two Pi setup but now I am only getting about 90K reports. This is over a 75% reduction in reports and I can’t figure out why.
On possible concern is CPU utilization. When I run the “top” command I am showing dump978 using ~48% CPU and dump1090 using about ~31%. Total CPU usage is around 80%, this is higher than I would have expect but I think it should still be OK.
Others have mentioned issues related to power but I have an inline meter for testing and I am supplying a clean 5.15v and 1.3A. I don’t think that is an issue.
I have a heat sync on the system and it is running steady at 44C so I don’t think it is heat.
I am out of things to check and could use any suggestions.
Thanks in advance.
