Is My DVB-T RTL SDR Dongle Healthy?
« on: January 02, 2018, 03:09:39 AM »
How To Test If Your DVB-T RTL SDR Dongle Is Healthy

Following two options are described below:

OPTION-1: Dongle plugged into Windows Computer.
OPTION-2: Dongle plugged into Raspberry Pi.

.

OPTION-1: Dongle plugged into Windows Computer.

STEP 1 of 3:
Install dvb-t rtl driver zadig if not yet done so, as detailed below.

(1) Download Zadig 2.3.exe from http://zadig.akeo.ie/

(2) Plug the DVB-T or ProStick in your Windows Computer.

(3) Follow the steps below:

(A): Double click Zadig 2.3.exe to run it.
The window below will open.


.
(B): On main menu, click "Options".
On the drop-down, place a check mark beside "List All Devices".


.

(C): From list of devices, select "RTL2838" which is actually DVB-T/ProStick.
Now click button which will either say "Install Driver" or "Reinstall Driver"

.
.

STEP 2 of 3:
Download RelWithDebInfo.zip from here:
Download Link: http://osmocom.org/attachments/download/2242/RelWithDebInfo.zip

Web Page: https://osmocom.org/projects/sdr/wiki/rtl-sdr
(scroll down to bottom of page to find download link)

STEP 3 of 3:
  • First EXIT your AirNav RadarBox 6.01 software to make the Dongle free for test.
  • Un-zip RelWithDebInfo.zip. It will create a folder RelWithDebInfo.
    Inside this folder there is another folder rtl-sdr-release which contains several files and 2 folders named x32 and x64.
  • Go to folder x32. You will find many rtl tools in it as shown in screenshot-1.
  • Double-click file rtl_test.exe to run it.
    A command console will open and if Dongle is OK, it will give output as shown in screenshot -2.

OPTION-2: Dongle plugged into Raspberry Pi.

STEP-1:
Install the test tools package rtl-sdr
Code: [Select]
sudo apt-get update
sudo apt-get install rtl-sdr

STEP-2:
Stop dump1090 to free your Dongle for test

Code: [Select]
#choose one of the following commands,
#depending on which version of dump1090 you have installed.
#If you are not sure, issue all three one by one

sudo systemctl stop dump1090
sudo systemctl stop dump1090-fa
sudo systemctl stop dump1090-mutability


STEP-3:
Now run the test command
Code: [Select]
rtl_test -t

If your Dongle is OK,
AND
Properly connected to Pi,
you will see this output
Code: [Select]
