Radio frequency scanners
RTLSDR is a very cheap (around 20 USD) software-defined radio that uses a DVB-T TV tuner dongle. In this recipe, we will cover connecting an RTLSDR device with Kali Linux to test whether it was detected successfully.
Getting ready
We will need some hardware for this recipe. It's easily available for purchase from Amazon or from https://www.rtl-sdr.com/buy-rtl-sdr-dvb-t-dongles/. Kali already has tools for us to get going with it.
How to do it...
We connect our device and it should be detected in Kali Linux. It's common for the devices to behave inaccurately. Here is the recipe to run the test:
- We will first run the test using the command:
rtl_test
The following screenshot shows the output of the preceding command:
- We may see some packet drops. This is because of trying this in a VM setup with only USB 2.0.
- In case there are a lot of packet drops, we can test it by setting a lower sampling rate with
rtl_test -s 10000000

- Now, we are all set to move on to the next recipe and...
