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 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 users guide for information on using special features of our dongle. 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 users guide).
- HF Direct Sampling Mode - Listen to 500 kHz - 24 MHz with direct sampling. Simply connect an HF antenna to the SMA port, and choose the Q-branch mode. 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.
- 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.

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 dongles is directly from our store on this page, or the local resellers listed above. Pricing Changes Unfortunately the global supply chain and component shortage crisis has forced us to increase pricing over the past few months. We are hoping that in 2022 the crisis will be resolved and we will be able to reduce pricing again. |

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's 4.5V bias tee is NOT for this LNB. 11.5 - 14V enables vertical polarization and 16 - 19V enables horizontal polarization.

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. 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. 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. Amazon 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. Amazon 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. 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. Direct 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. eBay 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. Amazon 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. If you are monitoring ACARS or air traffic signals then you may want an air band bandpass filter if you find that you have lots of interference from nearby stations such as FM broadcasts and Pagers. eBay 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. Amazon 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. Direct 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. eBay 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. 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. Direct 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. eBay 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. Amazon 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. Amazon 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. Amazon A Raspberry Pi is a credit card sized computer that runs Linux, or even Windows. With it you can connect an RTL-SDR, run a server, and then remotely send a signal or processed data such as ADS-B aircraft locations back via WiFi or Ethernet cable. Amazon 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. Amazon 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. Amazon 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. eBay 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. Direct 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. Direct 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. Amazon

Hi there, I’ve had a V3 RTL-SDR for a couple of years now. Love it! I’ve gotten a lot of use out of it. I was wondering if a V4 RTL-SDR is planned and if so, what improvements will be made to it?
Just waiting for Amazon to restock the bundle. This looks like a very interesting item.
It showed up, I added it to my cart, looked around to see if I wanted anything else, and it then showed out of stock again… ARGH!!!
Should have hit the checkout as soon as it showed up!
I hope that the NanoVNA will be back in stock soon. Does anyone have any news about it?
Thanks.
The 2+ hversion is discontinued and has been replaced by the 4+ version
Hi guys,
I want to check out DRM by listening to the transmissions of Radio Romania International in central Europe. There is a DRM-App available here:
https://drmsoftradio.starwaves.com/
However, they write that the support of RTL devices are experimental, only. Is there anybody who tried out already, if it works?
Thanks a bunch
Alex
Hi how is the shipment of RTL SDR to India. Is there any problems with the customs on letting the package through?
No problem recently, unless you’re doing large bulk orders. However please do keep an eye on the news and inquire with customs yourself, as India is constantly changing their import rules.
ok will do and thank you for ur reply 😀
Yep recently I ordered an RTL-SDR full bundle from India and was “luckily” all fine with no extra customs.
Oh that’s great! I ordered mine a couple of days ago. Could you tell me how long did it take for the delivery?
Hi, Some ordering advice please, I’m in Bulgaria (EU), I can’t order direct as of 1st July re VAT regs, Amazon UK don’t ship to mainland Europe because of brexit, Amazon DE says product can’t be delivered to your country, I don’t have a card accepted by Aliexpress.
Also between Saturday and Monday the price increased 10Euro which now means I’m not gonna get 2 inc delivery for my 100Euro budget, are the tcxo’s running out after the delivery woes I missed my chance due to being away for work for a couple of weeks, Are there likely to still be stocks at the end of August and how far will you go with the price increases before you pull the stock?
So after further research the 49euro dongle on amazon de is a fake and i see you don’t actually have an EU amazon store which is where the confusion kicks in, the fake is using the .blog branding on his ad.
USA site from like above savs no fees to be collected, so to clarify, the 13 bucks delivery includes the VAT normally payable at the doorstep?
Bona fide EU rtl-sdr.blog store would be a big help combat the myriad of fakes and confusing regional variations, I almost bought it simply because the branding was dot blog….
You can order from Aliexpress or eBay from 1 July onwards, they automatically charge the VAT to EU customers and provide the IOSS code for the package. So there’s no delays or payments required at the border.
Pricing is up due to the global component shortage, so we need to temper demand as it’s looking like we’ll run out in Q4 otherwise. It won’t go back down again until the component shortage is over – estimated early 2022. But we won’t be increasing pricing any further than it is now, even if stocks get very low.
We are looking into a direct EU store, however it won’t be cheaper than direct + the new IOSS VAT, as VAT is charged at some point regardless on if you order direct or order locally.
And please do take care with the fakes, the scammers will be looking for their opportunity with the supply shortage as they don’t use the components that are in shortage. Rather they use cheaper components that are still available. https://www.rtl-sdr.com/avoiding-fake-rtl-sdr-blog-v3-clones-2021-supply-chain-updates/
Do u ship to India, I am perplexed as the eBay store won’t ship to India , but it can be shipped if I order on the website here itself. Thought of asking beforehand , so that I don’t end up ordering and it gets cancelled later on.
For India, please purchase directly on our store. Shipping is still a bit of a mess with India, but packages are getting through.
Is the RTL-SDR Blog dongle compatible with the RTL-SDR or SoapySDR libraries. Both appear to support the chipset, but neither lists this particular dongle as being compatible.
The RTL-SDR Blog dongle is an R820T2 RTL-SDR, and all R820T2 RTL-SDRs will be identical in terms of the drivers used. Please confirm operation of the dongle with rtl_test.
Have you already delivered your goods to Russia? Is it possible?
Yes, shipping to Russia is fine.
If i order more than one thing, do you guys packaging them together or seperate?
If it’s a single order with multiple items we will package them together, unless there is too many items to fit within the postal weight/size limit. In that case it will be split.
If you make separate individual orders we will ship them separately.
I bought the V3 and antenna kit right before the holidays via the Amazon store. The two longer antenna elements of the dipole both have male connectors, but the sockets in the plastic hub are also male. Can I do anything about this? The shorter elements are both fine.
I was able to fix this issue with a pair of pliers and a vise. Problem solved!
I received a brand new RTL-SDR V3 R820T2 RTL2832U purchased through their official sales channel, which showed a technical problem. I reported it to the RTL-SDR admin which replied me very timely recognizing the failure and offering a replacement. I want to remark their unmatched professional approach in solving the issue. I would say that sometimes worth to use official sales channel to benefit of this kind of support. Thanks much!
This is really good to know. Sometimes thing’s happen, rtl-sdr is doing a good job. I’m just getting started and this is the stuff I like to hear.
hello administer.Is Worldwide stlll delivering goods to china now？

Hello, sorry about this issue, seems to either be a warehouse packing or shipping issue. We have already replied to your email and are sending a replacement set ASAP.
Very nice products very good customer support thank u guys very much Cant wait to buy more items thank u again
Thanks For your Fastest Delivery
I purchased the rtl-sdr dongle kit that has the small tripod and suction cup holder for the antenna elements. The suction cup holder came missing the large nut that you tighten to secure the pivot ball in one spot. What do I need to do to get one? I bought it through Amazon. Thanks !
Hi Kevin, please contact us at [email protected] with your address and order number and we’ll get that out to you ASAP.
Email sent. Thanks for your help !
Is it known when the Stratux 1090 MHz + 978 MHz Splitter and Saw Filter will become available again?

Wow, it changes to “Shipped” already. 😀
Thanks For your Fastest Delivery ever.

Thanks,

HELLO sir can you plese tell me you have SDR DONGLR RTL-SDR BLOG V3 R289T2, RTL 2832
Yes, but I have not used it yet. I need to get the appropriate software.
Can the QO-100 bullseye be used for GEO weather satellite’s.
A quick search for the bullseye LNB specification gives:
Input frequency: 10489 – 12750 MHz
LO frequency 9750/10600 MHz
LO frequency stability at 23°C: +/- 10 kHz / or +/- 30 kHz
LNB gain: 50 – 66 dB
Output frequency: 739 – 1950 MHz (low band) and 1100 – 2150 (high band)
So if the transponder is between 10489 and 12750 MHz then yes, if not then no.
I do not know a lot about it, but I think that most of the High-resolution picture transmissions for weather satellites are in the L-band and not the Ku-band, so probably not. But I’m not an expert.
I would like to know if the QO-100 Bullseye TCXO LNB work with the RSP1A when they say you need 12-19V bias tee power injector and the RSP1A has Software Selectable 4.7V @ 100mA?
Am I understanding this wrong. Thanks…
You’ll need your own external 12V-19V bias tee as part of your receiver setup. External bias tees are available cheaply on most marketplaces. It won’t work with the RSP’s 4.7V bias tee.
Does anyone have a direct phone # to reach the Rtl-sdr.com people for direct orders..???

啥时候补货

hi this vinay from INDIA in Aliexpress says not deliverable to india and Amazon.in listed at 85$ +shipping charges can it possible to ship directly from you
Sorry there are political issues with shipping to India from China at the moment. It seems that all shipping methods are blocked.
what about amazon India why it is listed at 6427 rupees ( 85$)…?
A local reseller might have stock with high prices due to the inability to replenish their stock.
Is shipment available to India?
Yes its available but it seems it will be having a delay than usual.
(But, I’m facing a new issue payment is not getting made though international transactions are enabled in my debit card. Not sure where the issue is. If you did the payment, It would be helpful if you update it here.)
