Pure Digitals award winning1. Evoke series of radios broke the 1. DAB take up has increased since. The BBC and other DAB broadcasters have been encouraging DAB take up by promoting a number of features which are either new or improve upon former technology in their sales literature. The benefit of DAB is that due to the use of multiplexing technology and encoding technology, broadcasters including the BBC and EMAP have been able to launch exclusive digital radio stations alongside their existing analogue radio stations. Broadcasters also state that DAB offers better reception, without the problems of interference that are more noticeable through analogue radio. DAB radios also come with features such as station lists, so listeners do not need to retune their receivers, as well as scrolling text, providing information such as breaking news, travel information or the latest track information. DAB has also been marketed as having two major advantages over analogue radio broadcasting in that using MPEG 1 Audio Layer IIlossy audio compression technology and more recently DAB using High Efficiency Advanced Audio Coding, parts of the audio spectrum that cannot be heard by humans are discarded, meaning less data needs to be sent over the air. This, as well as multiplexing technology, allows a number of channels to be broadcast together on one frequency as opposed to one channel for analogue radio broadcasts. National, local and regional DAB ensembles use the same frequency for the area they cover. Using a single frequency network, an ensemble broadcasting a number of stations can cover the same area as a number of FM frequencies which would be required to cover the same area for one station. The BBC carried out successful tests of a single frequency network in London before launching its national DAB ensemble. Criticisms of DAB in the UKeditDAB technically provides low audio quality in the UK due to 9. MP2 audio codec, which provides poorer sound quality than FM quality assuming good reception on both DAB and FM. In addition, DAB stations broadcast in the UK use a bitrate between 2. A bit rate of 2. 56 kbits has been judged to provide a high quality stereo broadcast signal. Also, a large and growing number of music stations are only transmitting in mono. Indeed, the bit rates used by the radio stations on other digital platforms, such as cable, terrestrial and satellite are usually higher than on DAB, so the audio quality is also higher. For example, all of the BBC stations use higher bit rates on the digital TV platforms than on DAB apart from the BBC World Service on Freeview. On the other hand, an Ofcom survey, which was undertaken due to many consultation responses citing poor DAB quality, found that 9. DAB listeners thought DAB was at least as good as FM. Ofcom estimates that even after extra spectrum has been allocated to DAB, around 9. DAB, either because there is no space for them on a local DAB multiplex, or because they cannot afford the high transmission costs of DAB that the multiplex operators are charging. Ofcom announced in 2. Digital Radio Mondiale DRM as an option for local stations unable to secure carriage or unable to pay the high transmission costs of DAB. The success of the small scale DAB multiplexes may alleviate this issue to some degree. One of the drawbacks of DAB and DAB has not been addressed. In simple terms the frequency of a broadcast is the carrier frequency i. In order to carry any information the carrier frequency must be modulated. The signal at the receiver radio is then demodulated and the information is retrieved. The demodulators for FM signals are almost instantaneous so that one can have radios in different areas and move between those areas to hear the broadcast continuously. In contrast the demodulators for digital signals take a finite time and each digital radio takes a different time to demodulate the broadcast signal, so that if you move between different radios that are spatially apart you are likely to hear the same part of the broadcast twice or miss parts of it depending on the time to demodulate the signal of the individual radios. The other drawback with DAB is that it is all or nothing. This page is a guide aimed at helping anyone set up a cheap radio scanner based on the RTL SDR software defined radio as fast as possible on a Windows system. If you have any trouble during the installation, please see the troubleshooting guide further down the page. We also have brief instructions for getting started on Linux and OSX at the end of this page. Please note that the RTL SDR is not a plug and play device.

USB driver, so also ensure that Win. USB is selected in the box after the arrow next to where it says Driver this is the default selection. Note that there has been some confusion for a few people over this step. The goal is to install the Win. USB driver. So to be clear, the box to the left of the arrow shows the currently installed driver, whereas the box to the right of the arrow shows the driver that will be installed in the next step. The first time you open zadig the box on the left will show either None, or the default DVB T drivers installed by Windows RTL2. UUSB, depending on your Windows configuration and version. Click Replace Driver. On some PCs you might get a warning that the publisher cannot be verified, but just accept it by clicking on Install this driver software anyway. This will install the drivers necessary to run the dongle as a software defined radio. Note that you may need to run zadig. USB port, or want to use two or more dongles together. Open SDRSharp. exe and set the Source drop down boxto RTL SDR USB. This Source tab is on the top left.

Press the Play button the right facing triangle. Your RTL SDR software radio should now be set up and ready to use If everything has worked you should be able to start tuning to frequencies. Important Dont forget to also adjust the RF gain settings by pressing the Configure button looks like a cog up the top next to the Play button. By default the RF gain is set at zero. A gain of zero will probably receive nothing but very strong broadcast FM increase the gain until you start seeing other signals. Next Steps. After getting your RTL SDR set up with SDR we recommend investigating the following Check out all our featured articles on this blog for various RTL SDR related projects and tutorials. Upgrade from the stock antenna. For optimal reception you should use an outdoor roof mounted antenna. The optimal antenna will depend on the frequency and project you are interested in, but for a general all purpose antenna we recommend a Discone or planar disk antenna pdf. If you are using your RTL SDR for HF with an upconverter such as the Spy. Verter then we recommended using SDR with the special decimation drivers. This will allow you to zoom in on the small bandwidth signals used on HF without loosing resolution. Check out our store for various RF accessories such as filters, LNAs and antennas.
