Welcome to the FR24 Decoder/Feeder sign up wizard!

Before you continue please make sure that:

 1 - Your ADS-B receiver is connected to this computer or is accessible over network
 2 - You know your antenna's latitude/longitude up to 4 decimal points and the altitude in feet
 3 - You have a working email address that will be used to contact you
 4 - fr24feed service is stopped. If not, please run: sudo systemctl stop fr24feed

To terminate - press Ctrl+C at any point


Step 1.1 - Enter your email address (username@domain.tld)
$:nnnn@gmail.com

Step 1.2 - If you used to feed FR24 with ADS-B data before, enter your sharing key.
If you don't remember your sharing key, you can find it in your account on the website under "My data sharing".
https://www.flightradar24.com/account/data-sharing

Otherwise leave this field empty and continue.
$:[エンター]

Step 1.3 - Would you like to participate in MLAT calculations? (yes/no)$:yes

IMPORTANT: For MLAT calculations the antenna's location should be entered very precise!

Step 3.A - Enter antenna's latitude (DD.DDDD)
$:dd.dddd

Step 3.B - Enter antenna's longitude (DDD.DDDD)
$:ddd.dddd

Step 3.C - Enter antenna's altitude above the sea level (in feet)
$:700

Using latitude: 34.6596, longitude: 136.1306, altitude: 700ft above sea level

Validating email/location information...OK

The closest airport found is ICAO:RJOO IATA:ITM near Osaka.

Latitude: dd.dddd
Longitude: ddd.dddd
Country: Japan

Flightradar24 may, if needed, use your email address to contact you regarding your data feed.

Would you like to continue using these settings?

Enter your choice (yes/no)$:yes

We have detected that you already have a dump1090 instance running. We can therefore automatically configure the FR24 feeder to use existing receiver configuration, or you can manually configure all the parameters.

Would you like to use autoconfig (*yes*/no)$:yes

Submitting form data...OK

Congratulations! You are now registered and ready to share ADS-B data with Flightradar24.
+ Your sharing key (nnnnnnn) has been configured and emailed to you for backup purposes.
+ Your radar id is nnnn, please include it in all email communication with us.
+ Please make sure to start sharing data within one month from now as otherwise your ID/KEY will be deleted.

Thank you for supporting Flightradar24! We hope that you will enjoy our Premium services that will be available to you when you become an active feeder.

To start sending data now please execute:
sudo systemctl start fr24feed

Saving settings to /etc/fr24feed.ini...OK
Installation and configuration completed!
