<br />
The '''RTL-SDR''' is an inexpensive and widely used software-defined radio (SDR) receiver. The USB dongle is based on the Realtek '''RTL2832U''' chipset.<br />
<br />
=== Installation ===<br />
<br />
To begin using the RTL-SDR dongle, enable it with the following configuration:<br />
<br />
<syntaxhighlight lang="nix"><br />
hardware.rtl-sdr.enable = true;<br />
</syntaxhighlight><br />
<br />
This setting enables <code>rtl-sdr</code> udev rules, ensures the <code>plugdev</code> group exists, and blacklists DVB kernel modules. This is necessary to allow access to RTL-SDR devices without requiring root privileges, since udev will assign ownership of RTL-SDR USB descriptors to the <code>plugdev</code> group.<br />
<br />
To use the RTL-SDR dongle without <code>sudo</code> access, add your user to the <code>plugdev</code> group:<br />
<br />
<syntaxhighlight lang="nix"><br />
users.users.<user>.extraGroups = [ "plugdev" ];<br />
</syntaxhighlight><br />
<br />
After making these changes, rebuild your system configuration.<br />
<br />
To verify that everything is set up correctly and the dongle is working, run:<br />
<br />
<syntaxhighlight lang="bash"><br />
rtl_test<br />
</syntaxhighlight><br />
<br />
=== Troubleshooting ===<br />
<br />
==== <code>rtl_test</code> requires sudo ====<br />
<br />
If <code>rtl_test</code> or other RTL-SDR utilities require root access to function, make sure your user is a member of the <code>plugdev</code> group. Run:<br />
<br />
<syntaxhighlight lang="bash"><br />
groups<br />
</syntaxhighlight><br />
<br />
If <code>plugdev</code> is not listed, add the group to your user’s <code>extraGroups</code> in your configuration, rebuild the system, and log out and back in for the changes to take effect.</div>Chris143
