One thing to note is that this adapter can get downright hot while working. When connected, your phone may ask what to do about the connected USB device, so choose the appropriate option. You may need to take off any case in order to get a snug fit. Step 1: Connect the RTL-SDR to Your SmartphoneĬonnect the RSL-SDR dongle (which should already be connected to the antenna) to the USB Type-A female port on the OTG adapter, then connect either the USB Type-C or Micro-USB male end to your smartphone's charging port.

If you're on the go, a portable power bank may also be a good idea. In these cases, it's wise to look for an OTG adapter with an additional USB-C or Micro-USB female port to accept charging at the same time.

Not all Android phones will be able to power the RTL-SDR by itself, and even if so, when you're using it for a long time, it'll drain your battery.
Anker Powerline Adapter for USB-C - MSRP $7.99 ( Amazon | Anker).RTL-SDR Blog RTL2832U R820T - MSRP $21.95 ( Amazon | RTL-SDR Blog).My Samsung Galaxy S8 uses USB Type-C, but yours might use Micro-USB. You'll also need an OTG adapter that converts the USB Type-A output for the RTL-SDR dongle to whatever type of USB input your phone uses. We recommend the RTL-SDR Blog RTL2832U R820T2 1PPM TCXO SMA V3 for $21.95. Instead, you can use an OTG adapter to plug your RTL-SDR into an Android app and listen in directly on your smartphone.įor the hardware, you need to have an RTL-SDR dongle.

Most laptops are far larger than the receiver itself, so the inconvenience of carrying around a laptop to use your RTL-SDR dongle can be discouraging.įortunately, drivers are available that allow Android phones to use and understand the RTL-SDR receiver, so it's no longer necessary to carry around a Linux computer to use your RTL-SDR on the go. While handy, not everyone has or wants to bring a desktop or laptop computer anywhere they might want to listen in on radio broadcasts.

In order to use a $20 RTL-SDR dongle, the usual route is to install GQRX on a Linux computer to be able to interpret the input from the receiver. Using a Linux computer, you can pipe the audio (which sounds like random noise) through an encoder to render it back into normal-sounding audio.įor a hacker, that all means that a simple $20 piece of hardware can give you access to the entire 500 kHz to 1.7 GHz range of radio frequency communication. While encoded transmissions share the digital signature of a "waterfall," looking like a strip of digital data rather than a wavy line an analog voice transmission makes, it is relatively easy to decode them. For some reason, much police dispatch traffic is both unencrypted and unencoded. Once this is done, you can easily find analog voice transmissions to listen in on. Typically, an RTL-SDR setup requires a computer to be able to interpret the input from the receiver. Don't Miss: Build a Radio Listener to Decode Digital Audio & Police Dispatches.For listening in on staff chatter, a hacker can use an RTL-SDR dongle to silently listen in on radio conversations before determining the best course of action. For a hacker, it translates into the ability to tap into unencoded radio messages using most common commercial two-way radios.
As a result, many of the processes done by dedicated hardware are now done by a computer, making the entire radio system very low-cost, flexible, and easy to get into.īeing able to take a cheap tuner originally meant for digital TV, such as Realtek's register-transfer level (RTL) DVB-T COFDM modulator, allows anyone to receive radio frequencies over a huge range. The basic requirements for using an SDR are a computer, a sound card or signal processor, and a radio-frequency (RF) receiver to receive the signal.

Why SDR MattersĪ software-defined radio (SDR) takes the parts of radio tuning that was normally done by crystals or local oscillators and accomplishes them with software instead. While encoding and encryption are increasingly used in radio communication, an RTL-SDR adapter and smartphone are all it takes to start listening in on radio conversations happening around you. Everyone from first responders to hotel cleaning staff use radios operating in the sub-megahertz range to communicate, often without even encoding the transmission.
