Where to Buy RTL-SDR RTL2832U DVB-T Tuner Dongles

At RTL-SDR.com we sell significantly improved premium RTL-SDR dongles but keep our profits low and offer free shipping in order to maintain low retail pricing. We strongly believe that our V3 and V4 dongles are currently the best 'bang for your buck' RTL-SDR dongles available on the market. Please see the V3 features pdf datasheet here for full information on the improvements made, and our V3 or V4 users guide for information on using special features of our dongle. (V4 datasheet and guide coming soon!) If you are new to RTL-SDR check out our about page first. Briefly, our dongles come with the following improvements:

  • <1 PPM temperature compensated oscillator (TCXO) – Accurate tuning and almost zero temperature drift (2 PPM max. initial offset, 0.5-1 PPM temperature drift)
  • SMA female antenna port – Generic dongles use the less common MCX or PAL antenna ports. SMA is more common, so more adapters and antennas are available for it. It is also more durable and has lower RF insertion losses.
  • 4.5V USB powered bias tee - This allows the RTL-SDR to power low noise amplifiers (like the LNA4ALL, HABAMP, RTL-SDR Blog ADS-B LNA) and active antennas through the coax cable. Can be enabled in software (see V3 / V4 users guide).
  • HF Direct Sampling Mode (V3) or HF Upconversion (V4) - Listen to 500 kHz - 28.8 MHz with direct sampling on the V3 model, or upconversion of the V4 model. There is a built in 25 MHz low pass filter, but additional HF filters may be required for optimal performance (e.g. to attenuate strong MW AM).
  • Aluminium case and passive cooling - These units come stock with an aluminium case and passive cooling via a silicon thermal pad. This stops reception failing due to heat when used above ~1.2 GHz.
  • (V4 Models) - Improved front end filtering. The V4 model is less prone to being saturated by strong broadcast stations.
  • Improved Antennas - We provide an excellent dipole antenna starter kit for newbies. Use the included mounts and extension cable to mount the dipole in good position for optimal reception. Receives terrestrial and VHF satellite signals.
  • Various additional improvements compared to other RTL-SDRs – R820T2 tuner, higher quality passive components, a choke on the USB line to reduce USB noise, a much improved PCB design for significantly less internal spurs and noise, various break-out pads, improved ESD protection, additional bypass capacitors and ferrite power line chokes, improved front end matching circuit, a modified power design for improved long term reliability, and a better LDO.

Counterfeit Warning

No one in particular owns the "RTL-SDR" concept, so anyone can sell their own RTL-SDR dongles. On this site and on various marketplaces we sell our own custom modified and improved RTL-SDRs under our brand "RTL-SDR Blog" and "RTL-SDR.COM". On marketplace sites like eBay/Aliexpress etc scammers may be falsely selling their own dongles under our brand names. The dongles with blue or green cases or square rectangular silver cases with four screws, or those advertised as "Pro" are not ours. Those dongles use poorer quality components, are designed cheaply, and may not have all the V3 features. We cannot provide support for counterfeits and these do not help support the running of the blog and the design of new products. The best place to purchase RTL-SDR Blog V3 or V4 dongles is directly from our store on this page, or the local resellers listed above.

QO-100 Bullseye TCXO LNB
QO-100 Bullseye TCXO LNB

Includes 1x QO-100 Bullseye TCXO LNB

This is a TCXO stabilized LNB for the QO-100 geostationary amateur satellite and other Ku-band satellites. Manufactured by Othernet. Standard LNBs used for QO-100 require modifications to be made to the circuit as the crystal needs to be replaced with a TCXO in order to avoid frequency drift. The Bullseye LNB comes with a highly stable TCXO which has less than 10 kHz offset even in outdoor conditions.

The Bullseye LNB is the world's most precise and stable DTH/consumer Ku-band down converter. Even a VSAT LNBF costing hundreds of dollars more is no match for the performance of the Bullseye 10K LNB. Each unit is calibrated at the factory to within 1 kHz of absolute precision against a GPS-locked spectrum analyzer. Under outdoor conditions, the stability of the LNB is well within 10 kHz of offset. As a bonus feature, the Bullseye 10K provides access to its internal 25 MHz TCXO through the secondary (red) F-connector. This reference output can be used to directly monitor the performance of the TCXO over time.

NOTE: Requires a 12-19V bias tee power injector, the V3/V4's 4.5V bias tee is NOT for this LNB. 11.5 - 14V enables vertical polarization and 16 - 19V enables horizontal polarization.

Recommended accessories from other sellers

Note that some of the links below are affiliate links which help support the costs involved with the running of this blog. However, all the products listed are what we actually do recommend regardless.

Antennas

Probably the most important part of a radio system is the antenna. There is no one size fits all antenna, every different design will have a trade off. For instance, wide band antennas can receive more frequencies, but will have less gain at any one particular frequency. If you want to receive everything then get a wide band antenna. If you want to receive one frequency with optimal reception, find a tuned narrow band antenna.

Discone Antenna
Discone Antenna

Discones are wideband antennas. This makes them ideal for the RTL-SDR as using a Discone will allow you to receive at almost any frequency with decent performance.

 
FlightAware ADS-B Antenna
FlightAware ADS-B Antenna

A 1090 MHz ADS-B antenna from FlightAware. Is weather proofed and has 5 dB of gain. Uses an N-type antenna connector. See our review post for more information.

Upconverters

The lowest frequency an RTL-SDR can comfortably tune to is about 24 MHz. An upconverter allows you to use your RTL-SDR on HF frequencies which are between 0 - 30 MHz. They work by shifting frequencies between 0 - 30 MHz "up" by a fixed amount into a frequency range that is receivable by the RTL-SDR.

Spyverter
SpyVerter Upconverter

Currently we recommend the SpyVerter as the upconverter of choice. Although it was designed to be used with the Airspy, it works perfectly with the RTL-SDR. It uses a 120 MHz oscillator, has excellent filtering and can be powered via USB cable or via the bias-tee on our RTL-SDR Blog dongles. The SpyVerter uses an innovative new architecture that reduces overloading, has better SNR than other options and can operate all the way down to DC.

With the above performance and features, the included metal case and adapters and at a similar or even lower price compared to other upconverters we think this one is the best value. See our review post for more information.

 
SV1AFN Upconverter
SV1AFN Upconverter

An alternative to the SpyVerter is the upconverter designed by SV1AFN.

It based on the ADE-1 mixer chip, uses a 200 MHz oscillator, has good filtering and works almost down to DC.

 
Ham-It-Up Upconverter
Ham-It-Up Upconverter

Another recommended option is the Ham-It-Up Upconverter.

This one like the SV1AFN is also based on the ADE-1 mixer, but uses 125 MHz oscillator and is based on an open source design. There is also a metal case available on Amazon and eBay. However, currently we would recommend the SpyVerter or SV1AFN over this option.

RF Filters

RF filters connect between your antenna and RTL-SDR dongle. They help to significantly reduce out of band interference and noise which is very helpful when trying to improve signal strength.

 
FlightAware ADS-B Filter
FlightAware ADS-B Filter

FlightAware sell a very affordable ADS-B band pass filter. Many users have reported significantly improved reception when they started using this filter. This is probably the best filter to get if you are interested in ADS-B. See our review post for more information.

 
ADS-B HABamp LNA + Filter Combo
ADS-B HABamp LNA + Filter Combo

We also highly recommend the ADS-B HABAmp for receiving ADS-B signals. This is a filter + LNA combination that works very well and will significantly improve ADS-B performance.

We've tested these ourselves with the activatable bias tee in our units and found them to definitely work very well.

 
Multi HF Bandpass Filter
Multi HF Bandpass Filter

This product is great for if you are using an upconverter together with your RTL-SDR, or other SDR. Contains seven band pass filters that range from 1.6 - 2.5 MHz, 2.5 - 4.7 MHz, 4.7 - 7.5 MHz, 7.5 - 14.5 MHz, 14.5 - 21.5 MHz, 21.5 - 33 MHz and 33 - 56 MHz.

Low Noise Amplifiers

If you have long runs of coax cable then a low noise amplifier (LNA) can help to significantly improve your reception. Coax cable is lossy and the longer it is the more your received signal is attenuated. By adding an LNA near the antenna this loss can be reduced.

LNA4ALL
LNA4ALL

The LNA4ALL is a very affordable wide band low noise amplifier that is very commonly used with the RTL-SDR. Has the ability to be powered externally from any voltage between 6V - 9V, or with a simple modification with 3V - 5V in bias tee mode.

We have tested the LNA4ALL in bias tee mode with the activatable bias tee in our units and found it to work well.

 
Other LNA's
Other LNA's

There are also several low noise amplifier circuits that can be found very cheaply for sale on eBay and most will do a good job. Unfortunately most don't provide a bias tee option like the LNA4ALL or HABamp does. Currently we recommend LNA's based on the SPF5189Z chip as they have wideband good performance, and are cheaply produced.

Other Accessories

Active USB Extension Cable
Active USB Extension Cable

Ideally you want to get the RTL-SDR dongle as close to the antenna as possible. Normal USB cables have a length limit of about 5m before they stop working, but with an active USB cable this can be extended up to 10 to 15 meters.

We recommend these Monoprice cables as they have been reported to work successfully with the RTL-SDR dongle.

 
Active USB Extension Cable
RG6 Coaxial Cable

We recommend using RG6 coaxial cable for most links between your antenna and RTL-SDR. RG6 is low loss cable and it is also very cheap because it is used commercially with satellite TV installations.

RG6 is 75 Ohm cable. Note that the mismatch between 50 and 75 Ohm impedances is completely negligible for RX applications.

 
Clip on USB Ferrite Core
Clip on USB Ferrite Core

Noise and interference can sometimes be induced in the USB cable itself which can show up in the RF spectrum. To stop this noise use clip on ferrite cores on the USB cable. These cores help to suppress unwanted currents in the USB shield.

 
USB OTG Cable
USB OTG Cable

A USB on-the-go (OTG) cable is required to use the RTL-SDR on Android phones with software like SDR Touch and Wavesink. We recommend trying to find cables that come with power plugs so that you can use it with a power pack. Using an RTL-SDR can increase CPU usage which can quickly drain a mobiles battery.

 
9:1 Balun
9:1 Balun

If you are using a long wire or random wire antenna with a HF modded RTL-SDR or an upconverter you should use a 9:1 impedance transformer to get good SWR.

There are also several other alternatives available on eBay that use a larger iron core.

 
Wideband Noise Source
Wideband Noise Source

A wideband noise source can be used together with an RTL-SDR dongle to perform measurements on filters and to measure the SWR of an antenna.

See our tutorial here for more information.

 

Recommended alternative SDRs

Airspy
Airspy

Airspy SDRs have high performance RX capabilities with mid tier pricing. Their units really shine when used in tough RF environments, such as in RF environments with strong and weak signals together. The Airspy is an excellent upgrade from an RTL-SDR dongle. 

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP and HackRF.

 
SDRplay RSP
SDRplay RSP

Another good mid range SDR is the SDRplay RSP line of receivers. These SDRs are great value for the price and can receive HF frequencies without an upconverter. Previous iterations were behind the Airspy in terms of overall performance, but the RSP1A and newer models are on par.

See our review post for a comprehensive comparison between the Airspy, SDRplay RSP1 and HackRF.

 
HackRF One
HackRF One

The HackRF One is a relatively low cost TX/RX capable SDR. It is designed for radio experimenters and it has a very wide band frequency range from 1 MHz to 6 GHz, and a wide bandwidth of up to 20 MHz and an 8-Bit ADC. It is probably the most versatile SDR that exists at the moment, but in a compromise it does not have the best quality RX or TX performance. Thus it is perfect for experiments like reverse engineering and testing RF devices, but it is not intended to be used as a commercial radio or ham radio.

Despite some broken itens that came, the product is amazing. Even in a fast try, using the dipole kit antena inside my home, it was possible to receive SW content. The audio quality is something completely different from “generic” dongles… congrats…

Lilian

I placed my order on March 15, 2018. Now is April 26, 2018 and nothing is heard about my package. I checked the RT361811045HK traking number and on March 26, 2018, the message is “Handed to carrier / Left for destination”.
I bought things from you, but the packages came quickly (maximum 3 weeks). This package is delayed for a month or more.
Has the package not lost on the way?

Dimitrie

Hello from Romania,
Just received my RTL SDR Blog V.3 + Dipole Antenna Kit, and I’m happy to announce that all the packed items are straight and sound, and it works…. after completed SDR# QSG for Windows, I stood a second… and realized that I have bought a glorified cheap FM tuner. It’s no better than my ’80s ITT Touroport 220… let alone my Sangean ATS-803A!!! ( still can’t believe I sold the latter ).
All in all, after fiddling with some settings, I’ve got it to work on Kubuntu 16.04.3 with Gqrx, works as stated by the blog authors.
No frequencies under 24 MHz, except for those imaged spurs that intersect on the waterfall, as described by sm5bsz…
Even on Windows 10, direct sampling does not SEEM to work, I mean I left connected the provided diapole antenna and adjusted setting according to the official guide. Should I be able to receive something? I have a 400 kW powerhouse closer than 120 KM North, on 1053 KHz.

Thank you in advance for your time taken!

P.S.: This comment is not meant to exaggerate the disadvantages of the RTL SDR, but compare it to what I own now.

Max

Not completly setup and understood the software yet and already complaining that it does not work like a off the shelf receiver 😀
You cannot expect to receive the HF with the VHF dipole. The dongle do not have any front end filtering and you need a good antenna outside and probaly a 30MHz low pass filter.

Dimitrie

Well, did my research, my apologies!
I have quite a HF-hostile EMI at my grandmother’s house…

Dimitrie

After some getting used to it on FM, I absolutely recommend it for RURAL area users! Signals are weak enough for the receiver front-end, so I managed to pick up a lot of stations! – over 90 of them.

B W

What is up with the book showing as over $300?

B W

Thanks, looks like it got fixed.

Zach W

I recently purchased the “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with Dipole Antenna Kit” and it took 5 weeks to receive it. I have been on the edge of my seat waiting for it but the antenna kit is not complete. It only came with one 1meter telescoping antenna, and one 13cm antenna. I also received a different base from the picture and then I also have the dongle. There are several pieces missing from my order. How can this get fixed in a timely manner?

Andy Schofield

Hi there,
Do you have any kit suited to AIS reception? There seems to be quite a lot of ADS stuff so just wondering if there are any recommended supporting devices that are worth considering for AIS e.g. filters.
Cheers
Andy

li

i want buy v3,if i use “Direct Sampling (Q branch)” need i welding Q lead wire or not?

JTC

Hello. I have the v3 and am able to activate direct sample mode in software. Several SDR programs are capable of this. No hardware modification is needed, although the stock telescoping antenna is not great for HF reception. Also check out this web page for more info:
https://www.rtl-sdr.com/rtl-sdr-blog-v-3-dongles-user-guide/

Good luck friend.

Dimitrie

I am looking forward to purchase the Dipole antenna kit or the RTL SDR V3 with the dipole antenna kit, can anyone tell approximately when they it will be in stock worldwide?

mb89

Your local reseller link to sweden is not working, seems like the site is down.

mb89

Now it works.. When will the rtl-sdr V3 with antenna come in stock at the china warehouse? I really want one..

Harold

After many hours of Googling, via Reddit, I have found you. You seem to have your act together. Very nice.

Here is what I want to do:
1 – an inexpensive solution (e.g. < $50 US.
2 – a device that will work with available free software.
3 – Use the device as a signal tracker. The supporting device should (can be) an Android phone. I have a phone (not activated). I am trying to trace RF emissions within my house. I have an extensive Insteon installation and it does not work. The Insteon devices use two methods of inter-device communications. RF around 900 MHz, and a low frequency power line signal.
I need to be able to trace RF signal strength among the newer devices that us the RF. I bought a whole bunch of Insteon devices when they were new and touted the dual communication capability. Turned out, that years later, you needed all new devices to participate. I won't go into my opinion of this marketing ploy (nah, outright deceptive advertising with no attempt to compensate early adopters). Any way. I need to sniff 900 MHz.
4 – A general purpose spectrum analyzer. I live in an area with really spotty cell phone accessibility. What I want to be able to do is use an Android phone to wander around looking at cell phone signal strengths for various suppliers. So I can pick the best of he worst carrier. I probably have to activate one phone with a carrier to actually use it to find the best carrier. It is really annoying that a phone does not seem to be activated unless it is to a single carrier.
5 – Free or nominal cost software to accomplish all of these things.

OK – What are your suggestions for what to buy? Or am I simply being annoying.

Seasalt

In the L-Band antenna advertisement you state it Can receive Outernet L-Band signal.

Outernet has ceased transmitting their L-Band signal.

They are now preparing a new Dreamcatcher device which will receive a Ku satellite signal.

Hello

What options are available for an outdoor roof mounted antenna ? Signal reception with the default antenna is quite bad in my house.

Got the SDR with the antenna kit. works like a champ

Celia Hahn

I just received your SDR with Antenna kit and see that it uses RG 174 cable / connectors. I need to convert the RG174 connection on the SDR to RG6 — can you help in any manner – cannot find a converter anywhere.
Thanks and Happy Holidays

Max

You need this and this.

Tom Stiles

At one time you had just the antenna kit for sale at Amazon? I would like to review it on my YouTube channel, hamrad88. I have already reviewed the SDR dongle and other products of yours and have given them high marks in my reviews. I see you have the antenna set with the dongle but I already have reviewed that dongle. Thanks for your time and this great website.

Tom Stiles

Palto

I’am interested in measuring through sw in pi a doppler shift and power level of an adsb message. I think that the dongle with 1PPM TCXO should be suitable to get accurate measurements. Is any application or project already addressing this topic..? Has this dongle ever been used to return the ‘accurate’ value of the doppler shift or power level (eg. gain settings etc) . Thanks

ROBERT CARLSON MD

Dear Sirs:

I purchased one of your RTL-SDR V3 units. It works fine on VHF / UHF but I can’t get HF to work right. I have the latest SDR# software from AirSpy installed on Win 10 running in Direct Sampling Q mode. With a good HF antenna I can see plenty of strong signals on the SDR# display, some over SNR 30db but the AM, USB, LSB, DSB audio is barely discernible and buried in the noise, even on a strong signal like WWV. I’m not sure if it’s the hardware or a setting, though I have experimented for hours with various settings to no avail. Any suggestions?

V3 dongle can work on hf in direct sampling mode for this you have to select q mode in direct smapling for hf also need a loop anteena or few meter randome wire work perfectly. Many broadcast channels started in the evening time.

Could you provide an update on when the RTL-SDR V3 kit will be available thru Amazon? Its been 2 weeks since the last estimate.

J.Thomas

Hello. I recently purchased the RTL-SDR v3 dongle and have been having a great time exploring it’s functions and capabilities. I have been trying to reverse engineer an old GM key-less entry FOB for a truck I no longer have just for educational purposes, not to preform a re-play attack, but to decode the signal and read the sequence of numbers/characters being sent, but I am having some difficulty when it comes to recognizing the type of modulation used from the waveform pattern. I have identified it’s operating frequency and successfully captured several good samples of the signal it produces, but it does not appear to match any examples I have found on the internet and there is virtually no technical data on the FOB itself available. Can you recommend a reference source (book or website) that might provide me with low level information on how the various digital modulation schemes work?

Steve

Search OOK maybe and see if that looks like it.

Tito Castillo

It’s October 11th and it looks like the trl-sdr is not yet available through amazon (it says available in october). Can you tell us when it will be available?

Dave

Any update on when they will be available thru Amazon? Its been 2 weeks.

Jon

Hi. I would like to by the dipole + dongle package from amazon. when do you expect to have that available?
thanks!

Win DLL by osmocom (RelWithDebInfo) seems not export any I2c control function…
there are alternatives maybe ? also no function to control the general purpose bus
it could be useful if supported in software…

Thanks

in addition to my previous msg, I connect the smartphone to the rtlsdr with an otg cable that powered both devices.

Hello.

I’m a blind bcl listener, I plugged the RTLSDR Blog 3 dongle on Adroid with SDR Touch app, because the Windows and Mac programs are not accessible with the screen reader software.
I would like to receive some BCL signal in am, and ham radio in ssb, but unfortunately I do not get any useful signal.
I set preference / direct sampling to the “branch q direct sampling” function useful for short waves,
I use a wire antenna of 10 meters, and with my Sony icf 7600 I received many signals in same frequences.

Tanks.

James

Did you figure this out?

AlexP

Hello,
some software mean to use the v.3 i2c bus for extenal
devices ?

Tim

Hi Alex, it’s used to turn on a relay in v3 dongle to allow power to an LNA if you choose to use one.

AlexP

I meant External i2c devices,not the bias TEE

Oscar Corona

Hello, I have a house on the beach 10 miles from the city, I have an antenna of 11 meters for citizen band (27 MHz) to communicate to the city, a VHF antenna for Marine Band (156 MHz) and a UHF antenna 462 MHz) for recreational use, I am interested in buying the RTL-SDR kit with the 2 antennas, but I have some doubts,
Do I need something extra to listen to these frequencies ?
Can I listen those frequencies with the 2 antennas included in the kit ?
Can I use my own antennas, which adapters i need ?

Thanks

Jon

I ordered the RTL-SDR and antenna kit with economy shipping from China, and it arrived in the UK 5 days after dispatch, which is great.
I am completely new to amateur radios, but setting up SDR# and the dongle was very simple, and I am surprised how good a reception I am getting on airband – even with the antenna indoors.
I have made a minor alteration to the set-up which has enabled me to hear weaker signals much better. Between my laptop and the RTL-SDR dongle, I added a 2 meter USB extension lead and moved the dongle away from my laptop. I then added ferrite chokes to each end of the USB cable.

mesodef

Is there any updated ETA on when the RTL-SDR Blog v3 w/ antenna will be back in stock on amazon? I would like to order one and I’m debating ordering from china vs waiting for amazon stock (preferably choosing the faster option).

Hans J. Albertsson

You say repeatedly that we should buy these items from “worldwide chinese warehouse”, but there is no link, so HOW?
