STEP-1: Prepare OS

1.1 - Download and write Raspbian Lite image to microSD card.

https://downloads.raspberrypi.org/raspbian_lite_latest

1.2 - Enable SSH
After image is written, and while the microSD Card is still in the Laptop/Desktop, open File Explorer (Windows) or Finder (Mac), and open the drive named “boot” . This will open the /boot folder of Raspbian. In this folder create a new text file and rename it ssh

1.3 - Slip microSD card into RPi and power-up.

.

STEP-2: Serialize the two Dongles:

Serialize dongles to following serial numbers:
Dongle #1: 00000101
Dongle #2: 00000102

Is this for comparing dongles or so people can expand their coverage by having 2 antennas around their house or is this for a different purpose?

Adding 2nd instance of FlightRadar24 feeder

This assumes that you have already installed FR24 feeder, and now going to add it’s 2nd instance to use data from 2nd instance of dump1090-fa/2nd dongle.

.

STEP-1: Prepare config file “fr24feed2.ini”

sudo touch /etc/fr24feed2.ini 
sudo chmod a+rw /etc/fr24feed2.ini 
sudo nano /etc/fr24feed2.ini

.
Copy-paste following into /etc/fr24feed2.ini
NOTE: Replace xxxxxxxxxxxxxxxx by your actual feeder key

receiver="beast-tcp" 
fr24key="xxxxxxxxxxxxxxxx" 
host="127.0.0.1:31005" 
bs="no" 
raw="no" 
logmode="1" 
logpath="/var/log/fr24feed2" 
mpx="no" 
mlat="yes" 
mlat-without-gps="yes" 
use-http="yes" 
http-timeout="20"

.

STEP-2: Prepare service file “fr24feed2.service”

sudo nano /lib/systemd/system/fr24feed2.service

.
Copy-paste following into /lib/systemd/system/fr24feed2.service

[Unit] 
Description=Flightradar24 Feeder 
After=network-online.target

This is an optional extra. It depends on user what for he wants to use it.

You could want to use two rtl-sdr dongles with different gain settings.
That can help to cover aircraft far away and very close at the same time.
Close to an airport for example.

Or you want to have an extra antenna focused in one direction.
Or you somehow have two antennas which cover half of the sky each.

Anyway i’ll just leave this here:
GitHub - wiedehopf/combine1090: Combine data from multiple ADS-B receivers into one readsb decoder / tar1090 webinterface

If you configure the source ports appropriately you can use it to obtained a webinterface that shows the aircraft from both receivers.
If you want MLAT results from both you’ll have to change the settings for piaware2 to either listen on 31105, or you can just make the piaware feed the results into port 29004.

You might want to explain how to get the 2nd feeder-id.
Foolproof method in case it’s already screwed up:

sudo systemctl stop piaware2
sudo rm /var/cache/piaware2/feeder_id

Change piaware2.conf:

[...]
allow-manual-updates yes   # updated by fa_piaware_config
feeder-id
receiver-type other
[...]

Having a blank entry helps with potentially having a feeder-id configured in piaware.conf.
piaware.conf is read first even for the 2nd piaware, then piaware2.conf is read.
Having the blank entry makes sure no feeder-id is really configured even if the other config file is read first.

sudo systemctl start piaware2

piaware will now get a fresh feeder-id which can be claimed.
(PiAware - Claim and Link a Brand New PiAware Ground Station - FlightAware)

Hummmm :thinking:

Interesting. Thanks for the tips, source and explanation. I now see some advantages to this setup.

9

Is it a pi to install two antennas to receive?

10

To have 2 stations, the normal way is to have everything two:

In this unusual setup, one can still get 2 stations, but saves one RPi as below:

| |RPi|Dongle|Coax|Antenna|
|—|—|—|—|—|—|
|Standard Setup|2|2|2|2|
|This Setup|1|2|2|2|

.

12

When creating this config file:

CONFIG_FILE_piaware=/etc/piaware2.conf

Maybe add this line (no value):

feeder-id

This is to make sure the feeder-id from the first installation is not used if it is configured in /etc/piaware.conf
(/etc/piaware.conf is always read first, it’s hard-coded)

Now when someone wants to claim their 2nd receiver it will work instead of the already existing feeder-id being used for the 2nd receiver.

Claiming the station will work just as well with the empty feeder-id set in piaware2.conf.
The new assigned feeder-id is just saved in /var/cache.

13

I have tested installs with and without a blank feeder id line in /etc/piaware.conf and /etc/piaware2.conf.

Did not make any difference for claiming new feeder id.

I have just now finished running the script on a fresh buster image, and did not add any feeder id anywhere, and got two brand-new feeder ids after reboot:

pi@raspberrypi:~ $ cat /var/cache/piaware2/feeder_id
43b75ca0-a0f6-411b-bb9f-0720a7a65c47
pi@raspberrypi:~ $ cat /var/cache/piaware/feeder_id
f61ed614-1df0-4b0a-9476-d505007b8e53

I can claim any one or both of these. However since I already have feeder ids for both I will simply delete these brand-new ones from cache, then add the ones I have to file /etc/piaware.conf and /etc/piaware2.conf and restart both piaware & piaware2

14

Can this script also enable FR24 feeds?

15

Well, it only makes a difference if you already have a feeder-id configured in /etc/piaware.conf
(if it’s only in the cache it’s not a problem)

So assume before using your script, someone wanted to get back his id because he made a new install.
As such he set it via piaware-config (which puts it in /etc/piaware.conf).

Now he uses your script and wants to claim the 2nd station, which doesn’t work as it’s using the feeder-id from /etc/piaware.conf instead of automatically getting a new one.
This issue can be avoided by setting feeder-id to nothing in piaware2.conf.

On a related note: You don’t need to delete the feeder-id from the cache, if a feeder-id is configured in the configuration file it takes precedence and the cache is updated to the new id.

Welcome @ua549
Glad to see you in this forum after recent encounter in FR24 forum. :wink:

No, this script does nothing for fr24feed, but as it has created 2nd instance of dump1090-fa which outputs Beast data on port 31005, you can do it manually easily:

(1) First install fr24feed by their bash script given below.
Set receiver=“beast-tcp”, host=“127.0.0.1:30005”. (Caution: do NOT set receiver=“dvbt”)

sudo bash -c "$(wget -O - https://repo-feed.flightradar24.com/install_fr24_rpi.sh)"

.

(2) Next create 2nd instance of fr24feed manually as shown in this post:

Adding 2nd instance of FlightRadar24 feeder

.

17

Well the script is meant for a virgin OS image without any piaware or dump1090-fa installed on it. It is not meant to run on a microSD card which already has piaware & dump1090-fa installed.

The script first installs the piaware and dump1090-fa (package install) and after that creates & configures files for 2nd instance. Thus both the piaware and piaware2 have no feeder-id anywhere on the microSD card, neither in .conf nor in cache. When Pi is rebooted or piaware instances are restarted, they get brand-new feeder-id in cache. These newly acquired brand-new feeder-ids in cache can be either claimed, or deleted/replaced by already existing feeder ids

18

OK, I will try it when my RPi 4 arrives to replace a RPi 3 B that’s currently feeding FR24, FA, and serving 2 laser printers.

That said I’m a bit confused about dump1090-mutability and dump1090-fa. Do they co-exist or is only one installed? If so, which is better?

19

Do NOT try it on RPi4.
It wont work on RPi4 due to rtl driver issues which is still unresolved.
Wait untill this problem of Pi4 is resolved.

It works fine on RPi 2 & 3

20

Only one of them can use the dongle, so it really makes sense to have only one installed.

dump1090-fa is actively developed by mutability.
dump1090-mutability on the other hand is no longer actively developed.

The local map style is a matter of preference, but you can have the old style with dump1090-fa as well:
GitHub - wiedehopf/dump1090-retro-html: Old dump1090 webinterface adapted for dump1090-fa

21

Thanks! I’ll move to dump1090-fa when I update software.

@ua549

In this thread I have posted the method to create 2nd instance of dump1090-fa and 2nd instance of piaware.

Over an year ago, in FR24 forum, I have posted the method to create 2nd instance of dump1090-mutability.

With 2 instances of any version of the dump1090 (mutab or fa), if you also create 2 instances of fr24feed and 2 instances of piaware, you can have 2 independent stations on one Pi.
