Use RPi with FR24 image with additional application and second USB TV stick

[MichiC00]

Hello,

I would like to use my RPi 4, which is successfully running the FR24 image , for an additional project.
The additional project will also use an additional USB "TV" stick (to capture 433Mhz signals).

Should I start with a Raspbian image and then install all the software manually?
Or can I simply continue to use the FR24 image without any problems?

In addition, there is of course the question how I can specify that the correct stick is used for FR24.

Thank you in advance for your help.

Best regards,
Michael

Serialise the sticks and change the launch line to use just one and leave the other alone.

And probably better to switch to dump1090-fa

Thank you for the detailed explanation.
I will try it out later and get back to you if I have any questions.

STEP-1:
SERIALIZE BOTH DONGLES

For 1090 Mhz dongle: use 8-digit serial # 00001090
For 433 Mh dongle: use 8-digit serial # 00000433

(1.1) Issue following command to install serialization software:

sudo apt install rtl-sdr

(1.2) Unplug ALL DVB-T dongles from RPi

(1.3) Plugin only that DVB-T dongle which you want to use for dump1090-fa. All other dongles should be unplugged.

(1.4) Issue following command. Say yes when asked for confirmation to chang serial number.

rtl_eeprom -s 00001090

(1.5) Unplug 1090 Mhz dongle

(1.6) Plugin only that DVB-T dongle which you want to use for other App. All other dongles should be unplugged.

(1.7) Issue following command. Say yes when asked for confirmation to chang serial number.

rtl_eeprom -s 00000433

(1.8) Unplug 433 Mhz App's dongle

IMPORTANT: After completing above commands, unplug and then replug both dongles




STEP-2:
CONFIGURE FR24FEED/DUMP1090-MUTABILITY TO USE DONGLE SERIAL # 00001090

Edit file /etc/fr24feed.ini

sudo nano /etc/fr24feed.ini

In item "procargs=" add --device-index 00001090 (see attached screenshot)

save file
Restart fr24 feed

sudo systemctl restart fr24feed

In above post, I gave only how to enter 1090 mhz dongle's serial # 00001090 in fr24feed's config file.

As I am not aware of details of "433 Mhz App". I cannot tell how to enter it's dongle's serial # 00000433 in that App's config file. You have to check the 433 Mhz App's config to see if there is a way to specify it's serial number 00000433 in it's config file.
