Buy RTL-SDR Dongles (RTL2832U)

Where to Buy RTLSDR RTL2832U DVB-T Tuner Dongles

The R820T2 RTL-SDR is currently the cheapest, most common and most performing in terms of general sensitivity. The R820T2 has a frequency range of  24 – 1766 MHz and is fully 100% compatible with any software for the older R820T.

We at now sell improved RTL-SDR dongles at low prices with free shipping. See our post on these new units for a full overview of all the features. Our dongles come with:

  • 1 PPM temperature compensated oscillator (TCXO) – Accurate tuning and almost zero temperature drift (2 PPM initial offset, 1 PPM temperature drift)
  • SMA female antenna port – Most 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 insertion losses.
  • R820T2 tuner – More sensitive than the older R820T tuner. 100% compatible with software for the older R820T.
  • Improved component tolerances – Allows the RTL-SDR to work more optimally over all frequencies.
  • Experimental: 4.5V USB powered bias tee - Can be enabled by soldering two pads on the PCB together. This allows the RTL-SDR to power LNA’s (like the LNA4ALL and HABAMP) and active antennas through the coax cable.
  • Experimental: Break out pads for direct sampling - Allows easier soldering to pins 4 & 5 on the RTL2832U for enabling the direct sampling mod.

R820T/R820T2 RTL-SDR

Another reputable place to buy a R820T2 RTL-SDR dongle is at the Nooelec Store. Nooelec dongles have an ESD protection diode, improved components and good phone and email support.

The older R820T’s are also still for sale by Nooelec at a lower price as well.

Click here to buy a Nooelec R820T dongle (Ebay)

There is also the Nano R820T package. These have similar price and performance to the standard sized package shown above. The Nooelec branded nano models come with improved crystal oscillators and capacitors compared to generic brands. The improvements help to increase frequency stability and lower the noise floor.

Also, take note of the uncommon Micro Coax (MCX) plug on these dongles. Check out the most commonly used MCX adapters below.

MCX Adapters

Most R820T/2 RTL-SDRs use an MCX antenna connection. To connect to antennas with different connectors you can use an adapter. MCX adapters are fairly cheap and most can be found on Amazon for under $10.

Below are some individual adapters for sale, but please note that our sets linked above work out much cheaper than buying several individually.

BNCFemaleMCX->BNC Female BNCMaleMCX->BNC Male
UHFAdapterMCX->UHF(SO239) Female FAdapterMCX->F Female
NFemaleMCX->N Female NAdapterMCX-> N Male
PALAdapterMCX->PAL Female  


The E4000 is more expensive as it has become rare since it has gone out of production. It has a frequency range of 52 – 2200 MHz with a gap from 1100 MHz to 1250 MHz.

The E4000 RTL-SDR dongle can still be bought from Nooelec on Amazon as well. Due to its rareness, the cost of the E4000 is slowly rising. These dongles used to sell for $20, but are now going for around $50-$100! Best to get them now if you need them before they sell out completely. Though note that for most cases an R820T2 unit is usually better.

Modded RTL-SDRs

Nooelec sell custom made TCXO RTL-SDRs. Unlike standard RTL-SDRs, TCXO RTL-SDR’s will not experience any frequency drift, and will have a very small PPM offset of around 0 – 2. These units also come with an aluminium casing included.

Ham-it-up Upconverter

Nooelec also sell the Ham-It-Up Upconverter. The ham-it-up is a quality upconverter that allows the RTL-SDR to receive HF (0 – 30 MHz) signals. It also works with other SDR’s such as the HackRF. The Ham-It-Up uses SMA Female connectors, so you will need an MCX->SMA Male adapter to connect it to the dongle.

The optimal antenna to use is highly dependent on the frequency you want to listen to. However, for general purpose scanning across all frequencies, we recommend using a Discone or Scantenna.

The Scantenna is a general purpose antenna with a frequency range of 30-1300Mhz and excellent reviews on Amazon. Most people find that the Scantenna outperforms a Discone in many situations. Scantenna’s go for around $50, but they are now getting difficult to find.

scantennaClick here to buy a Scantenna

The Discone is the ‘classic’ RTL-SDR antenna as it covers a wide range of frequencies like the Scantenna. A decent Discone can go for as little as $50.

RF Filters

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 have strong FM band interference a good FM trap band stop filter such as this MCM one can help reduce this interference. These can be bought for under $1 USD.

An ADS-B bandpass filter like this low cost one from can significantly improve the range and number of ADS-B messages received.

ADS-B FilterClick here to buy an ADS-B bandpass filter

If you are monitoring the air band for air traffic or ACARS you can buy 118 – 138 MHz bandpass filters.

Other RTL-SDR Related Purchases

Nooelec also sell handy aluminum cases for MCX RTL-SDR dongles which help with shielding from local interference.

If you have long runs of coaxial cable, a low noise amplifier (LNA) may aid in helping to ‘push’ weak signals through. We recommend the LNA4ALL LNA.

LNA4AllClick here to buy an LNA4ALL

Noise can appear on the USB cable which can show up in the RF spectrum quite easily. To stop this noise use clip on ferrite cables on the USB cable.

      Thanks for the interest!

      We’re just in the process of repackaging the units with antennas because the international postal system was much rougher than we anticipated. We found that they tend to crush parcels a lot, which pushed some of the antenna base screws down into the base (easily repaired with a screwdriver, but definitely not in the state that we want customers to receive them).

      We should be back to selling them normally by the end of this week, or early next week.

    I somehow managed to screw up the driver for the R280T trying to fix my Folio keyboard on my Winbook. Now it shows up as Bulk Interface 0 and Bulk Interface 1. Is there anyway to get it back to R280T?

    • admin

      Are you seeing that in Zadig? In Zadig the RTL-SDR should show up as Bulk in, Interface (Interface 0), or something like RTL2832. Just use Zadig to reinstall the WinUSB drivers on that interface 0 to get it working.

  4. Bob H

    Hey guys, I just bought your improved rtl-sdr dongle and it works great, but the only antenna I have is the telescopic antenna it came with, I also have a small unused radio dish. I tried to receive NOAA 19 with limited success. To actually receive a signal I needed to hold on the the antenna cable which reduced the static and allowed me to receive it for a small period of time. I cannot buy a different antenna at this time.

    What can I do to so I don’t have to hold the wire to get reception?

    • admin

      The telescopic whip antennas aren’t really designed for receiving satellites. Telescopic whip antennas can receive terrestrial signals well, but not ones from space. For NOAA you should build a QFH or turnstile antenna.

      That said you might be able to squeeze a bit more from the telescopic antennas by extending them to the correct length for 137 MHz (about 0.52 m), placing the antenna on a metal sheet like a cookie tin lid, and making an “ugly balun”. Coil up a few turns of the coax around a pencil (or preferable a ferrite rod) near the antenna base. That should reduce the noise a little.

      • Bob H

        Thanks for the quick reply, but the telescopic antenna that came with it has a fairly high noise floor on almost any frequency unless I hold on to the cable itself, by this I mean there are tons of strong signals that were wide, solid lines (Not FM) and then I held the antenna cable they go away for the most part and weaker signals show up like NOAA 19 and it improves the signal so much that it was static and then the signal was almost clear as day and I could actually receive NOAA 19 for a while and it gave me a clear image (I can post a picture if you want and I was at max gain, as that is what I needed to pick the signal up NOAA 19)

        Also when you say place it on a metal sheet do you mean the base or the antenna itself, and when you say near the antenna base do you mean the cable around the base, and is there a specific number of coils I should make?

        Sorry for the stupid questions, and thanks for the reply.

        • admin

          Sorry for the late reply. Yeah I mean put the base of the antenna on top of a metal sheet. Whip antennas like these are designed to be placed on top of a metal surface. There’s a magnet on the base for this purpose that will hold it there. I think that when you hold onto the cable you might be helping by acting as the ground, so adding a real ground plane should help as well.

          For the coil I mean to get say a pen and maybe make 3-4 turns of the cable around then pen, then tape it to keep it secure. Make the turns close to the base. If you have a ferrite rod then do it around this rod. It shouldn’t be needed, but in some cases this can help.

    • Ares

      Why don’t you replace the antenna? They’re cheap and plentiful. BTW, the R820T2 dongles perform worse in tests (especially in the experimental mode) than the old R820T ones and it would appear that in the advertised models the 1ppm claimed TCXO is actually a passive (no power) 20ppm smd crystal – it’s to do with the design of the R820T2 tuner.

      • admin

        What tests have you seen or performed that show the R820T2 is worse? All the results i’ve seen from other experimenters and our own tests have shown that the R820T2 is a little better than the R820T. Just search for R820T2 on this blog.

        Also these new units (not the old model linked by Jacob) really do have a real powered 1 PPM TCXO, it is not passive. There is a power trace for these units going into the TCXO to power it.

        • Ares

          I have not tested the model you are trying to sell, but I will ask the Chinese manufacturer for a few samples. The R820T2 tuner is designed with the ultra amateur people in mind who cannot be bothered to even get a good antenna for their setup. Any one of my R820T dongles has shown better stability than the new R820T2 ones and all the new so called TCXO dongles have so far been sold with a 20ppm SMD passive resonator. That said, would it be possible to get a link to some pictures to support your claim? I’d like to see that power trace and perhaps you could also tell us what TCXO is used in the design?

          • admin

            The main difference between the R820T and the R820T2 is the wider filters (whose width should have no effect on the 3.2 MHz RTL-SDR), but a side effect of the different filters appears to be slightly better RX.

            Not sure what you mean by the “ultra amateur people?”, the R820T2 is also used in the Airspy, a high performance SDR.

            Frequency stability has little to do with the tuner itself, it is all dependant on the oscillator. Close up of the power trace here 3.3V is tapped from one end of C2. The TCXO has no brand, but it is almost identical to the one used in the previous ThumbNet models which are also 1PPM temp drift, 2PPM initial offset.

            • Ares

              Please let me help you identify your quartz – and regarding the power trace I shall contact the manufacturer to confirm everything. (The reel was obtained from the dongle manufacturer)
              Thank you for your kind offer, but for what it does I have decided that I may buy your Airspy only when you’ve lowered your price a tad. Until then I’ll be happy to either use the Chinese dongles or make my own SDRs.

              • admin

                No its not that one, those look like passive XOs. We source our own TCXO’s from a separate supplier, they are 1PPM and powered like all TCXO’S need to be.

                Just to confirm we aren’t the designers of the Airspy, they are made by someone else.

                • Ares

                  By your own words you do not know what the brand of the quartz is. I helped you identify it as that is what the Chinese use. The rest is your blurb trying to save your sales.

                  • admin

                    It’s definitely not that XO in the image you posted. I 100% guarantee that the oscillator we use in the new units is a powered 3.3V 1PPM temp drift, 2PPM initial offset TCXO.

                    There is no brand, the TCXO is custom manufactured by our crystal supplier who have their own network of factory partners to choose from. 28.8 MHz TCXO’s are not very common, so they need to be custom ordered in the thousands. The closest thing to a brand is the supplier name, but I won’t reveal the supplier as that is trade secret (and I think you might be an RTL-SDR retailer too? since you talk of contacting the factory), but there are many similar XO suppliers to choose from in China.

                    Not sure why it is so hard to believe in a RTL-SDR with TCXO? Anyone can confirm the 1PPM drift by watching the drift on a signal over time. Other vendors have had TCXO RTL-SDR’s out for some time too, including ThumbNet, Nooelec and custom hand modded ones by someone in Japan.

                      Blurb. I’ve had the NooElec dongle here straight from China (NooElec written in silkscreen on the PCB) – came with the 20ppm crystal as pictured in my link above.

                      How can you tell everyone there is no brand? Someone manufactures those crystals after all and you don’t know who it is. Well, I got a reel full of those so called TCXOs from the same manufacturer you are talking about and they are not 1ppm.

                      I’ve had enough of all of you ripping people off by saying things that are not true about those products, ie. your claims about home modifying the PCBs, etc. The dongles are manufactured in China, all the printing is done in China and every board is modified in China.

                      I have no problem disclosing who makes them, do you?

                    • admin

                      Replying to your last comment here because the comment thread went too deep. The “brand” is the supplier name, but they just order the crystals from one of their factory partners.

                      Yes all the dongles are made in China, most by Newsky, the factory we and other vendors use. They have their own standard oscillators that they use on their standard units (the 20PPM SMD ones your talking about, and the 100PPM+ CAN package ones) – we used the SMD ones on our old models as they drifted a lot less than the through hole XO’s. But for these new ones we’ve gone ahead and ordered 1PPM TCXO’s from a crystal supplier, given them to Newsky, told them the required PCB changes needed to give them power, and then had them manufactured. To be clear, ours are not hand modified.

                      There really are hand modified ones for sale though, by Nobu in Japan (he sells them on, and there was also a US company doing similar hand mods who sold on eBay before.

                      EDIT: To comment below, yes NS may be traders, but they are the biggest gateway to the factories of these units.

                      EDIT 2: What the?! The base URL of the site this commenter linked in the picture he posted in an earlier comment ( redirects to a business that sells RTL-SDRs in the UK. We know this business as one that was actually selling and mislabelling the passive 20PPM XO dongles as TCXO’s before on eBay… I don’t like putting other sellers down as they provide a valuable service with local shipping, and will often promote them in posts if they provide a superior product, but really what on earth is going on here?

    Hi there. Am quite new with SDR and this site is awesome. Congratz!

    I really wanted to work something out with a new Radio I bought, so I ask: What is the recommended equipment to work with AM, FM and SW transmissions?

    Best regards

    When will the amazon USB sticks with antennas be back in stock? Is there a source for the antennas separately?

    • admin

      Hi and thanks for the interest. Due to the long Chinese New Year holidays we weren’t able to get our stock manufactured in time, and there are still big back logs that the factories are dealing with. We expect to be back in stock around early April, hopefully late March. Also, there’s no separate source for our telescopic antennas as we get them custom made for us. Sorry for any inconvenience!

  7. Dutch N0RDC Thurman

    Bought an Amazon dongle but there was ZERO documentation. Installed and ran SDR# but either I am doing something wrong or the HF is dead. Goes to 24mhz then gets quiet. Have a decent HF dipole Slinky that works great on my ICOM PCR100, but I want the better software control and support as my PCR100 is hard to find software for.
    Any ideas?!?

    • admin

      Most dongles won’t come with documentation, but all the set up info needed can be found on our quickstart guide. The R820T/2 RTL-SDR has a range of about 24 MHz – 1.7 GHz, so HF reception below 24 MHz is not possible. But it is possible to run experimental HF drivers (see the software menu at the top), do a hardware mod or buy an upconverter.

    • admin

      Yes you can get them that cheap, but remember they will take around 2-4 weeks to arrive vs a few days if buying from a local seller. Also the cheap ones won’t have any improvements made to them.

      • youp

        Okay, I think I’ll go for the cheap one, was going to order some stuff from aliexpress tonight anyway. I’m buying it for experimentation/fooling around, if I end up liking this stuff I’ll probably buy the R820T2 version, a quick google told me there’s a shop about 500M from my dad’s work that sells them. Also, I’m in the Netherlands, so buying them from your store won’t be an option probably. Thanks for the info/fraud check!

    • Randy M.

      As far as AliExpress, you may, or may not, get counterfeit product. I have ordered 3 items from them. 2 of the 3 were obvious counterfeits, with pretty bad silkscreening of the “real” manufacturers name. I’m talking about ordering a Neo Hybrid case for my phone, and getting a Neo HYB RID instead, lol. You get what you pay for though. Their dongle is probably “ok”, but I’d spend the extra to get one with the upgraded components if you get bitten hard enough by the sdr bug. Quality components will give you a much quieter noise floor.

    When are you guys going to have the SDR dongle sets with the telescopic antenna in stock? I saw the message saying they will be in a few days but its been weeks. Thanks!

    • admin

      There have been a few delays due to the holidays, but if everything goes to plan with the shipping from China, we should be in stock again by the end of this week. We’ll make a promotional post on the front page when they’re ready for sale.

      Not much other than ours come with the 2x telescopic antennas which is good for beginners who don’t have any antennas to use. On the other hand Nooelecs’ have phone support and they also sell more expensive models with the R820T2 chip which has slightly better sensitivity. They also ship outside the USA which we can’t do at the moment.

      We’re restocking ours in a few weeks and ours will also have the R820T2 chip and some other small improvements applied to them.

    I’ve tried to buy the R820T RTL-SDR in Amazon following your links, but it’s not possible for Spanish customers. I’ve find in the Amazon Spanish site and I found several vendors. While all of them have prices around 15-20 EUR, one from NooElec costs 308 EUR !!!. Where is the difference? I thought that almost these dongles where equal. All of them are RTL2832U+R820T.


    • admin

      Our branded ones are currently only available in the USA due to Amazon restrictions. All dongles are almost all the same, the Nooelec ones have slightly better component tolerances and better support, but not worth 308 EUR, they must have made a pricing mistake there. Go for any reasonably priced R820T.

    Hi! I am close to buy my first SDR hardware but I have not decided yet between NooElec RTL-SDR kit (with Ham It Upconverter) and the DX Patrol Ultra Wide Receiver. My last due dilligence to finally decide is about tuning of ISDB Digital TV (the standard for most of Latinamerica).

    Usually RTL2832U R820T is offered like DVB-T tuner (standard for Europe) but there is no mention for ISDB TV nor ATSC (North America standard for digital television). In the white paper of Rafael Micro R820T ( one can read that this chipset is also for ISBD and ATSC but my confusion comes from the advertisement of this dongle which is always as DVB-T shown on its plastic case, the antenna and the tiny remote control…

    Some days ago I did ask to DX Patrol manufacturer about if its dongle could tune ISBD TV and he said me that “by changing the software, you change the type of (SDR) receiver. You can still receive TV with it, but you will have a drivers conflict. You would need use different PC or so, but would be possible”. Unfortunately his answer was no so clear for a SDR beginner like me :s

    By the same way a sales representative at NooElec told me that she believes “the R820T has to be configured to receive ISDB and a slightly different circuit board is required. As such, I do not believe you can use these for ISDB”.

    What advice can all you folks give to me about this conflict :p ?

    Thank you all in advance!

      EDIT: I’m not 100% sure on this, but I think the RTL-SDR R820T based dongles are compatible with ISDB-T, assuming you install the correct drivers for TV watching.

      The DX patrol guy was just warning you that you cannot have the SDR drivers and the TV drivers installed at the same time.

      • Leopoldo

        Hi again admin!

        Such driver’s conflict may be the reason why some SDR hobbyst recommend not to install the software that comes in the CD package if I will not use this device for TV purposes? In my case is very obvious that I won’t because DVB-T is not the standard in Latinamerica (but ISDB), so the CD and the remote control is useless for me.

        Regarding the white paper of Rafael Micro R820T which mention that this chip features for DVB, ISDB and ATSC standards, so it appears to be a driver design issue as you (admin) mentioned. But certainly it is very rare that northamericans, latinamericans or japanesse SDR enthusiasts didn’t have created any drivers to take advantage of ISDB/ATSC USB TV dongles… (?) Why the DVB-T dongle is so advertised and associated to SDR?

        • admin

          Yes the conflicts are why you can only use one driver at a time.

          The RTL2832U chips SDR capabilities are kind of an accident which hasn’t been able to be replicated in ATSC dongles as they do not use the RTL2832U.

          DVBT and ISDB are pretty similar which leads to believe that the DVB-T dongles are the same as the ISDB ones, but Nooelec might be right that there are small differences in the circuitry which could cause it to not work on ISDB.

    Hai Admin… i want to buy a SDR. I have some doubts about it
    1,All DVB SDR same? ( multiple RTL SDR on ebay&Amazon)
    2, What is different R820T&E4000?

    Nooelec has now a nano usb stick and they say that he is better than the normal USB stick

    Did any one compare ?

    Tnx for info


  19. René Welter

    There is now a Nano stick awailable at Nooelec.
    They say even that he is better than the normal stick.

    Has anyone compared . .

    I have bought a E4000 Terratec t stick+ and Ham it up converter from Nooelec. My PC Windows 8, i7
    After I realised it is not compatible for Windows 8. Now I don’t know what can do with this device.

      Just Install Kali linux (free with almost all sdr tools preinstalled) at VMWare Player 6.x (free).
      Look at my comment under the topic of GSM decoding with the single script for Kali.

  23. Rolf

    I have just bought a dongle and have the software installed.but can not find the stick name in the field next to Play.
    Have find in the AUDIO tag the Input that shows MME ,s two with a REALTek name but can not reciev ant radio station can you advice me Cheers Rolf

    The plugin “Auto Tuner” does not exist in the file “” how to download Plugin of this site.
    Where can I find this “Auto Tuner” ?
    Help me

    • admin

      Hi, I just tested that download and it’s there, but a little hidden. You need to scroll down on the left menu, and click the [+] next to the Auto Tuner button.

    RTL-SDR can get spectrum upto 2200 MHZ ?and How many tolerance of rtl-sdr ?I want get spectrum of range 2110 -2170 Mhz of a RF generator,Can i do ?Thanks!

    • admin

      Only the E4000 RTL-SDR can go up to 2200 MHz maximum, so make sure you get one with the E4000 tuner chipset. RTL-SDR has 3.2 MHz maximum bandwidth, so you won’t get the entire spectrum all at once. The oscillator PPM tolerance is usually somewhere between 10-100 PPM error.

      • Hao Doan

        Thank you ! I can question more .Have type other of rtl-sdt that bandwidth about 100Mhz ? If with bandwidth 3.2Mhz and range measure frequency is 2110-2170 Mhz software can indentify start and end frequency that needn’t display spectrum all on screen ?Thanks!

        • admin

          All RTL-SDR’s have 3.2 MHz max bandwidth. Sorry, I don’t quite understand the final question, but you can tune to any frequency between 2110-2170 MHz and look at 3.2 MHz of the spectrum.

          • Leopoldo


            When you say to look at 3.2 MHz of spectrum you mean that at maximun zoom out of spectrum you will only see signals between two frequencies B – A = 3.2MHz ? (at maximum zoom out). For example: at the, the server of JO32KF ( allow me to see from 0kHz to 29,160kHz —> this imply that the bandwith of his SDR receiver is almost 30Mhz (or 29.16MHz)?

              In the DVB mode, the tuner demodulates the signal, and in the IQ mode, it passes the samples to USB. The maximum sample rate is 3.2M as noted above. But the highest stable sample rate is approx 2.8M.
