Title: RB VHF usb
Post by: D00B on September 26, 2022, 05:13:24 PM

Hello everyone. I’ve recently bought a RB VHF stick and am using a Raspberry Pi 3B on Buster.
I have read the guide here https://www.radarbox.com/sharing-vhf

Something throwing me off is the bit about using RTL-SDR-Airband software. Clicking the link takes me to GitHub but I don’t know what to do there.
If I just go straight to trying sudo apt-get update -y && sudo apt-get install rtl-airband-rb -y via ssh on the pi, I get the response “E: Unable to locate package rtl-airband-rb”

Is anyone pi savvy able to offer some guidance for me?

Thanks in advance.

You need to add Radarbox repository to your apt sources list.

(1) EASY AUTOMATED METHOD:
If you don't have RBFeeder installed, the following command will install both RBFeeder and the rtl-airband-rb package:

Code: [Select]

sudo bash -c "$(wget -O - http://apt.rb24.com/inst_rtl-airband-rb.sh)"


(2) MANUAL METHOD (FOR ADVANCE USERS)
The screenshot you posted shows you have Raspbian BUSTER.
You can further confirm this by following command

Code: [Select]

lsb_release -sc 


Issue following command to add RB24's BUSTER repo to your apt sources list:

Code: [Select]

sudo touch /etc/apt/sources.list.d/rb24.list

sudo chmod 666 /etc/apt/sources.list.d/rb24.list

sudo echo 'deb https://apt.rb24.com/ buster main' > /etc/apt/sources.list.d/rb24.list 

sudo chmod 644 /etc/apt/sources.list.d/rb24.list

sudo apt update 



Now issue following command to install airband

Code: [Select]

sudo apt-get update -y && sudo apt-get install rtl-airband-rb -y

Thanks abcd! I was hoping you come good having read so many of your posts before.

I’ll have a go now and report back.

Ok, that’s done and the conf file is now populated with the information provided in the guide.

My issue now is restarting the service.

The service is not found.

Thank you! All seems to have gone through correctly. Only issue now is it shows offline on the website which is a little odd

@abcd567

I seem to have another issue which is causing the service to fail.

If I issue the command

Code: [Select]

sudo systemctl restart rtl-airband-rb.service
I get the following error
Job for rtl-airband-rb.service failed because the control process exited with error code.
See "systemctl status rtl-airband-rb.service" and "journalctl -xe" for details.


Running this

Code: [Select]

systemctl status rtl-airband-rb.service
offers the response

Looking now at the code for the config using

sudo nano /etc/rtl-airband-rb.conf

shows the below which seems to relate to the 3 dots on line 6
The code was originally copied and edited where needed from here https://www.radarbox.com/sharing-vhf

Do you have any thoughts?
