Want HF too? You can modify the dongle for HF reception, but it's really a bad way of doing things. If you would like to do this please contact us and we'll be happy to walk you through it. However, we strongly recommend you take a look at the upconverter available in the link above which will let you listen all the way down to 100kHz or lower with impeccable sensitivity

After several hours of trying to get rtl_fm to work properly, I threw in the towel, and moved on to rtl_tcp, which acts as a little TCP server, sending I/Q data to a connected client. I had much better luck here. Running the program produced the following:$ ./rtl_tcpFound 1 device(s).Found Rafael Micro R820T tunerUsing ezcap USB 2.0 DVB-T/DAB/FM dongleTuned to 100000000 Hz.listening...Use the device argument 'rtl_tcp=127.0.0.1:1234' in OsmoSDR (gr-osmosdr) sourceto receive samples in GRC and control rtl_tcp parameters (frequency, gain, ...).
Have you tried running PowerSDR or PowerSDR/IF software? How about WinRad? These are all free programs. How about SpectraView? If you have not tried these for the PC, maybe you could find time to check them out. I might just order one and try it. It would be nice to know before I get one. I use PowerSDR/IF with an LP-PAN HF Pan adapter connected to an IF out from my Yaesu FT-950.
RTL-SDR is a very cheap $30 USB dongle that can be used as a computer based radio scanner for receiving live radio signals in your area (no internet required). Depending on the particular model it could receive frequencies from 500 kHz up to 1.75 GHz. Most software for the RTL-SDR is also community developed, and provided free of charge. Note that RTL-SDRs cannot transmit.
The origins of RTL-SDR stem from mass produced DVB-T TV tuner dongles that were based on the RTL2832U chipset. With the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) it was found that the raw I/Q data on the RTL2832U chipset could be accessed directly, which allowed the DVB-T TV tuner to be converted into a wideband software defined radio via a custom software driver developed by Steve Markgraf. If you've ever enjoyed the RTL-SDR project please consider donating to Osmocom via Open Collective as they are the ones who developed the drivers and brought RTL-SDR to life.
Over the years since its discovery RTL-SDR has become extremely popular and has democratized access to the radio spectrum. Now anyone including hobbyists on a budget can access the radio spectrum. It's worth noting that this sort of SDR capability would have cost hundreds or even thousands of dollars just a few years ago. The RTL-SDR is also sometimes referred to as RTL2832U, DVB-T SDR, DVB-T dongle, RTL dongle, or the "cheap software defined radio".
There are now many other software defined radios better than the RTL-SDR, but they all come at a higher price. Currently we think that the Airspy ($169) and SDRPlay ($99) SDR's are the best low cost RX only SDR's. There is also the HackRF ($300USD) which can both transmit and receive.
Radio components such as modulators, demodulators and tuners are traditionally implemented in analogue hardware components. The advent of modern computing and analogue to digital converters allows most of these traditionally hardware based components to be implemented in software instead. Hence, the term software defined radio. This enables easy signal processing and thus cheap wide band scanner radios to be produced.
This is dependent on the particular tuner variant used in the dongle, and the particular implementation. Some dongles, like our RTL-SDR Blog V3 also utilize the direct sampling mode which can enable reception below 28 MHz.
Generally, at least a dual core processor of some sort will be required for most general GUI based software defined radio software. Command line tools and ADS-B decoders may work with less powerful hardware. Single board PCs like the Raspberry Pi 3, and Android mobile devices can also run several applications.
The R820T2 is generally regarded as having better performance and sensitivity for most interesting frequencies compared to the E4000. For ADS-B, the R820T2 is much more sensitive at 1090 MHz. There are now also the R820T2 dongles, which offer increased sensitivity over the R820T. For these reasons, the R820T2 is currently the recommended dongle, unless you need the higher frequencies that the E4000 provides and are willing to pay a premium price.
Be careful when buying a dongle as certain sellers tend to misrepresent their devices (knowingly or unknowingly) as having compatible tuners, when in fact they may send out a device with an incompatible tuner. Also be wary when buying E4000 dongles from auction sites as there are many dodgy sellers incorrectly advertising R820T2 dongles as the rare E4000.
See our RTL-SDR store page for more information about where to obtain dongles from reputable sources. We now sell our own "RTL-SDR Blog V3" dongles which come with several key improvements for the SDR crowd and we recommend these for users who want to mainly use their dongle for SDR.
The $10 dongles were the very basic TV dongles that had many problems when used for SDR purposes. Even so, our SDR specific improved dongles used to only cost $20, so why are they now $30, and some brands even costlier?
No person or company owns RTL-SDR and all it's supported software and hardware in it's entirety. However, it was the combined efforts of Antti Palosaari, Eric Fry and Osmocom (in particular Steve Markgraf) who first discovered that certain TV dongles could be used for SDR. Osmocom in particular developed the first RTL-SDR driver which was released as open source.
Since then RTL-SDR has become a community based phenomenon. Certain companies such as us at RTL-SDR Blog have taken it upon ourselves to produce our own flavor of RTL-SDR dongles that perform better than the standard TV dongle. But none of it is possible without the wider community development behind all the free software.
Original pioneering discoverers: Antti Palosaari, Eric Fry and Osmocom. In particular Steve Markgraf from Osmocom who developed the first driver.Hardware Sellers: Chinese factories producing and selling generic TV dongles. Sellers of RTL-SDRs improved for SDR use like RTL-SDR Blog.Community Software/Hardware Devs: Anyone who has created software for the RTL-SDR, or has discovered and documented a hardware hack for the RTL-SDR.Community Bloggers: RTL-SDR Blog, and other bloggers/content creators who write and popularize RTL-SDR applications.Wider Community: Anyone using RTL-SDRs.
A few years ago we decided to create our own RTL-SDR dongle hardware that has significant improvements that benefit SDR users. Since then we've continued to improve our RTL-SDR hardware and are now at the V3 dongle.
If it has a metal case, that makes it easy to mate to another metal surface to radiate away the heat. I have one cheap USB dongle that gets extremely hot when alone, but all I do is clamp it onto a piece of metal about one square foot in size, and it conducts all the heat away very well, and it stays room temperature, even though I use it 24/7/365.
I have a new all in one win 10 machine and this does not work ,It will not install and zidag does not see it to set up drivers,yes these worked several years ago win 7,but now its all changed so please either update your software or fix these things so they work.
Most dongles that are compatible are advertised for receiving DVB and DAB broadcasting, these are both digital formats. The dongle you link to is for analog reception (probably PAL or SECAM) and looks to be several-generations-old technology given its requirements (Pentium 4).
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:
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 dongles is directly from our store on this page, or the local resellers listed above. 2ff7e9595c
