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 user 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 ~1.5 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, modified PLL circuit for better stability at 1.5 GHz and above, 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.

I was about to order the “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas” from Amazon when it became unavailable. They still have the dongle by itself, but I was hoping to get the antennas as well. Are they available separately? Or will the SDR+antenna item be restocked soon? (Your description says the Chinese warehouse will be restocked in a couple days; I don’t know about Amazon.) Please advise.

Slyker

Since the release of “RTL-SDR V3” nearly half a year, it is expected the new version (V4) devices in the near future?

JTee

I am a frequent visitor to Hong Kong from the UK. In fact I am here at the moment. Is there any physical outlet here where I can purchase the RTL SDR v3 and accessories? I was expecting to find such a place in Sham Shui Po but have had no luck.

You put a nice feateure in V3 with io pins expose but
how to drive them ?

I discover that rtl dll have io functions, but
not exported ???

Does the v3 RTL-SDR dongle support DVB-T2? Or is a version planned that will support it? I ask because terrestrial TV transmission in India uses DVB-T2.

I got my rtl-sdr.com dongle today and i tested it for short time in Direct Sampling mode.
Testing time – 12:00 (24 hrs metric), antenna: ~10 m wire /w out Balun, from window to maple.
1600×900 resolution images are presented.

http://images.vfl.ru/ii/1479893197/87deacf9/15069254.png – “silver”
When i saw an increased noise level in “silver” dongle, i wanted to start swear. But later i saw – your dongle can get signals, which i can’t get with generic even at night time, with good propagation conditions! And MCX connector in generic dongle have small “insert in\out” cycles.

Hello, rtl-sdr.com owners!

I can’t buy RTL-SDR V3 dongle from Ukraine.
“Sorry, but your Visa x-NNNN was declined. Please add another debit or credit card to complete your purchase.”
(NNNN is last four digits of my Visa card, not for publication).
Paypal marks all transactions with your store as ‘Denied’.
I can’t imagine what is I’m doing wrong 🙁

vasanth

You want to have debit card that will support international transaction.Some banks don’t accept paypal addition due to their security policies.So check with bank.

Hi,
I’ve ordered the “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas” kit more than a month ago. The EMS tracking says “Your item was delivered(UNITED KINGDOM GBGU 9) at 2016-10-06 08:44:00” but I haven’t received it yet. Is this normal and what should I do if not?
Thank you.

I don’t want to be an alarmist, but 3 out of 5 of my batch 2 dongles are dead. It looks to me like the RTL chip is cooking. Perhaps its my hub, but I don’t thin so.

AJ

Is there a problem with V.3 batch 2 (NYS 2016-9)? It’s performance is lacking compared with my 4 other dongles, spurs everywhere and gain fade outs make this a disappointing purchase.

Lao

Are there still ink rubbing off issues?

Max

My blog filter is stuck in China and there is no progress since 10/10. It doesn’t even seem to have reached the airport. Is there a way to know what’s going on?

Claudio

Now (Oct/10th) that the worldwide site has been re-stocked and is accepting orders again, could you confirm if the V3 dongles are the “Batch 2” ones as mentioned in the V3 user guide? (with a resettable fuse on the Bias tee)

thanks!
Claudio

Terry Gaff

Hi,
Does the new V.3 RTL-SDR circuit board have pads to which I can attach a switch so I can manually turn on and off the Bias-T power ? Just like in the previous version.

Cola

Have you thought to make 2 separate connectors for HF and VHF? I think 95% ppl use different antennas for HF and VHF (you can do a survey).
PS. Nice filter, if I saw only the frequency response, I never would have thought that it is based on SMD components.

paul

just bought fm trap. thank you sir for coming up with all these high quality devices and addons.
at this point i have spent enough money on rtl gadgets to have bought a nice shortwave radio. but i prefer the modular route. i can set it up anywhere and tinker with it endlessly. anyway, thanks again for a great product and a fantastic site. – paul from toronto

Nicolas

Good price for the FM band stop filter.

I just ordered one.

I hope you’ll keep on developping such SDR accessories in the future.

I already get RTL-SDR dongle V2 and V3.

A DAB band stop filter and a LNA would be usefull too.

Kevin

my kit came with a damaged antenna base. The coax connector that ties the antenna base cable to the dongle is missing the center pin so I am unable to receive any rf signals. I know this is the issue as when I take a short length of copper wire and gnetly inset it into the center of the antenna connector on the dongle, I get radio stations loud and clear. How do i get a replacement antenna base?

Max

Which kit are you talking about?
It is not damaged, it has a rp-sma connector instead of a sma

Hello.
I’m interested to order vs SDR.- “” “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas” “”
$ 24.95, on Italian money € ur about 23 ..
Problem … try to order on Amazon and i see .. “Not available for shipping on ..”

The I am living on italy …….. and Amazon is wonderful Also for no high expenses –
How can I do to have you here in Italy, someone in germany, switzerland Italy to HONEST prices? .. Here literally make the bins, (disappointments)
Thanks to those of you answer me in email.

PS. When you update to better use, as they often do not recognize the drivers. v1450

I recently received two of the new V3 dongles from rtl-sdr and I have to say they are a huge improvement over the two NooElec dongles that I have been using, My reception and decode of a ProVoice system, using Unitrunker and DSD+ is much better with these new dongles! Also the quality of the dongles and the included antennas seem much better as well. Very happy I made the switch.

Jon

I work with wireless microphone systems and we often use active antennas or in line amplifiers in our RF equipment. The wireless receivers or antenna splitters that we use, provide Bias T power up to 15V to supply active equipment.
I would like to use an RTL-SDR dongle connected to an output of the antenna splitter so I can see real time the signal received with the antenna in the system. Do you know if the Nooelec NESDR Mini2 I own can handle that 12-15V in it’s input? And could the new V.3 dongle? If not, what can I use to block that DC current to use an RTL-SDR with that purpose?
Thanks!

Jon Olabarriaga

Great info. This will work fine for my purposes.
Thanks!

Martin

Hello. At first thank you so much for your web! I can see that “RTL-SDR Blog R820T2 RTL2832U 1PPM TCXO SMA Software Defined Radio with 2x Telescopic Antennas” is sold out for international post (I am from Czech Republic, Europe Union). Will you please enable international post again? Hope yes, but if not then is it better to buy (e.g. over ebay) “NooElec NESDR Nano 2” or “NooElec NESDR Mini” or “NooElec NESDR Mini 2”? Thank you so much, Martin

Jan

Hi Martin, I’m from Slovak republic so …

I’m also waiting when they will be restocking and sending RTL-SDR to worldwide. Few days before I’ve decided to write them an email. Their response:

” Restocking is likely to occur next week, around August 8-12. “

Dmitri

Hi everyone.
I’m from Estonia and I’ve been waiting for them to restock it for 1 month now or so, because I think this is the best possible kit on the market. Really looking forward to it.

Bill L

Could you think about putting hardware revision numbers on the dongles. It would make it easier to keep track of the most current dongle in the reviews, promotions, etc. Thanks

Micheal S

Why don’t you guys add an LNA to your dongles like the flightaware ones have?

Max

Very good, and don’t forget the external FM band stop filters; possibly with two options: 1. single pieces complete with SMA/F connectors, 2. lot of 5 pcs. without SMA connectors

Hello, I wonder if you sell the separate telescopic antenna since I already have a dongle and plan to buy only the telescopic antenna and aluminum case

leandro

Hi, when is the dongle kit with 2x Telescopic Antennas going to be in stock in amazon? , it says June 12 but its still out of stock. Can Someone recommend similar antennas on amazon so I can buy just the dongle? , thanks!

singsonn

Hi, Does anybody know a good replacement for the MCM FM trap filter? It seems this one is not available for sale anywhere now…
Thanks!

Jeffrey Smythe

How good are NooElec dongles

AD5NL

NooElec blue aren’t bad but I recommend putting them in a metal case with a heatsink.

Aluminum foil will work but it blocks air flow which can make it get hot.

An Altoids tin and a thermal pad should work OK. Be sure to ground the case to the USB and antenna shields.

AD5NL

Also the RTL-SDR.com dongles are better, in my humble opinion, simply because they use an SMA connector. The adapter from MCX to whatever is going to cost you some money (I used a $10 SMA-MCX cable) and also some signal loss.

Homeboys-Scanna

Hello, Please when would the R820T2 RTL2832U be available. I urgently need it for my research. Thanks.

SwineOne

Quick newbie question:

I’m looking to receive broadcast AM using the direct sampling mod. Can I directly solder a loop antenna (similar to those found on boomboxes or A/V receivers) to the breakout pins? Or do I need anything in between the antenna and the RTL-SDR, like a transformer or balun? Thanks.

SwineOne

But what about impedance matching? Is a 1:1 transformer best, or should I use a different ratio?

Nick

The R820T2 dongle with TCXO works very well, but the lowpass IF filter doesn’t work compared to the older R820T dongles. I am using the SDR driver with IF bandwidth control and it works well on my old R820T, reducing the bandwidth for better out-of-band rejection, but the bandwidth is wide open on the new R820T2 dongle. With SDR#, I can see a narrow bandwidth when set to 2.4 MHz sampling and 350KHz IF bandwidth on the R820T, but not on the R820T2. Was something changed to disable the IF filter ? Can it be changed back ?
