I’ve given my brother a new SD card with the latest software. He can’t see any planes on his local map. The stats page shows 3 green lights and the pi has checked in within the last 2 minutes. The hourly reports page between 12:00 and 20:00 is when the old SD card was put in the pi
Any clues as to what the problem is?
Problem seems with dump1090-fa
Please post outpput of following commands
sudo pgrep -l dump1090
sudo journalctl -u dump1090-fa -n 15
This is what I get in a normal system
Looks like dump1090-fa isn’t running. This serves the data on port 30005 which piaware is missing based on your first screen.
Provide output of the command
sudo systemctl status dump1090-fa
and post it here
@abcd567 and @foxhunter Thanks guys. Looks like the dongle is broken.
@abcd567 what is the number that sudo pgrep -l dump1090 returns?
Sorry for the formatting but this is a copy/paste of a screen dump file.
pi@piaware:~ $ sudo pgrep -l dump1090
pi@piaware:~ $ sudo journalctl -u dump1090-fa -n 15

Potentially the stick has issues. Did you try using a different USB port?
The number is PID (process id) and it can be anthing. If the dump1090-fa is running, the output of pgrep command will be xxx dump1090-fa. If dump1090-fa is not running, there will be no output.
This may be due to either (1) dongle not inserted properly in USB port, or (2) bad USB port or (3) defective dongle. As suggested by @foxhunter, try another USB port. After changing USB port, issue following command
sudo systemctl restart dump1090-fa
After restart, check status by pgrep and journalctl commands I gave in my post above.
@foxhunter @abcd567 All working! My brother swapped USB ports and put the old SD card back in so not sure if it was a USB or an SD card problem. I’ll sort a new Pi out in case one of the USB ports is getting dodgy.
Thanks to both for your help.
One thing that had me confused was that I had 3 green lights and the stats page said I was connected to the Flightaware servers.

The 3 green lights on stats page show status of “piaware data feeder”, and not that of dump1090-fa. Also the connection to FA servers is established by “piaware data feeder”, and not by dump1090-fa. As the “piaware data feeder” was working OK, these indications on stats page were showing OK.

@abcd567 Many thanks for the explanation.
