Is there a way to log / record ADSB data locally without streaming it to ADSBExchange? I will be at an airshow without wifi (cell hotspot not available), but I still want the tracking ability. Is there a way to do this so I can play back the tracks later?

You could come up with something to pull the JSON data off the feeder and log it.

You can take a look at my implementation of a portal at [jprochazka/adsb-receiver](https://github.com/jprochazka/adsb-receiver)

If you are looking to implement something on your own, you can use [the following Python file](https://github.com/jprochazka/adsb-receiver/blob/master/build/portal/python/flights.py) as a reference in order to save data to an SQLite or MySQL database using dump1090 JSON as a data source. Mind you this is not tested against Readsb which the ADS-B Exchange image uses?

“[modesmixer2](https://web.archive.org/web/20180809183248/http://xdeco.org/)” used to save aircraft in a SQB database file  
and here is my command:

```auto
nohup ./modesmixer2 --inConnect localhost:30002 --inConnect localhost:30003 --inConnect localhost:30004 --inConnect localhost:30104 --inConnect localhost:30005 --web 1091 --location 53.xxx:-0.4321 --db BaseStation.sqb --frdb flightroute-iata.sqb &
exit

```

You will probably need to install in order to run the “modesmixer2”  
`sudo apt install -y libssl1.1 libssl1.1-dev`

EDIT:  
The version “modesmixer2\_aarch64\_rpi4\_Raspberry\_Pi\_OS\_20210228.tgz” does not work … ☹
