It would allow you to see what really you can do with different devices. Coming to the specifications, this device is a 2. It also includes a 2. This is another great device which is priced quite affordably but can both transmit and receive just like the other products we reviewed above.
It comes integrated with a receive amplifier and a transmit amplifier. This device may not exactly fit the definition of an SDR technically speaking, but it would offer pretty much everything a true SDR does. However, it does have a bit of a limitation in that it can only operate near the following frequencies:. You would be able to explore as much as you want and learn a lot while doing so without having to worry about any licensing issues.
This makes it a great way for beginners to venture into HF and learn more about it before even having to purchase a CB radio or any other type of radio for that matter. However, a particular downside is that it tends to perform poorly when used with a cheap inside antenna.
But with a good external antenna, the signals would flood in like you may not even expect. In fact, it can be used much more like a digital radio receiver than anything else. All said and done, this SDR radio offers an incredible value for money coming with a high-quality oscillator and lower noise levels too.
The benefits of using an SDR are certainly appealing enough for the amateur radio enthusiasts to get one of the above devices right away.
Let us discuss some of the more important ones below. As we mentioned at the beginning, an SDR can go a long way in helping a radio enthusiast discover useful information about RF that they can use to achieve a better performance from their radio devices.
Most advanced SDRs can both receive and transmit — and although not at the same time — it does offer a lot of flexibility to radio enthusiasts. Get back to us if you have queries regarding Windows, we will be happy to help you. Thank you, Microsoft Community. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. There is no error msg. Each of the apps appears to be working ok except that a scan of TV channels returns nothing - no channels found.
As I said before, the dongle worked perfectly with several software apps under Win7 but won't work with Windows I see from searches that many people have exactly the same problem with their Realtek RTLU devices. If I try to install the original CD drivers, or any other drivers that other users have found, Windows tells me that "my driver is already up to date". Device Manager shows Driver Version I am sure there are more recent versions available but Windows 10 insists on using I have found information relating to this problem on other forums.
A couple of items from apparently informed users follow - I would be very interested in your thoughts on these. Both solutions seem to have significant down-sides. There must be a better way! The problem getting it to work with Win10 is that default Device Installation Settings allows Windows to install or update with wrong drivers. Installing the correct drivers after Windows has installed the wrong drivers does not fix the problem. You may be able to uninstall the wrong drivers from Device Manager before installing the correct ones but I haven't tried that.
Running the System Restore, turning off driver updates in Device Installation Settings and installing the correct drivers gets it working! Search Windows settings for "Device Installation Settings" and turn Win 10 device driver auto updates off.
Turning it off stops Windows continually overwriting correct working drivers with wrong not working drivers. No need to turn Windows Updates off. Thank you for keeping us posted on the status of the issue and we appreciate the time and effort you have put in to resolve the issue. If the Windows update has failed to register and download the requisite drivers for the device, you can also use the vendor id of the device and look for it in the PCI Vendor and Device Lists.
Unknown and uninstalled devices will be listed under Other. The device will have a yellow alert symbol on it. The properties for the device will show that no driver was found. Each Hardware ID is comprised of some very useful information.
Make a note of the PID value. In cases where you have multiple device types listed, narrow down your search by also adding in the VID value. Once downloaded and extracted, you can point Device Manager to this driver to install the hardware. Please keep us posted on the status of the issue.
If it still persists, we would be happy to help you further. Unfortunately, I didn't get very far searching the pcidatabase but I have made significant progress!
On the assumption that it is Win10 Update that is overwriting the working driver s , I set my WiFi connection to "Metered" to prevent auto-updates and removed my Ethernet cable. I then unplugged and reconnected the TV dongle.
Windows then selected driver version Later, after reconnecting my Ethernet thus resuming the capability for auto-updates , Windows reverted to driver version I also received a pop-up telling me there had been hardware changes and I should reboot.
The problem would therefore appear to be - how can I force Windows to keep version The working and the Failed setups are identical except for the Hardware IDs.

This IF signal is amplified by a variable gain circuit, filtered, then passed onward for digitization.
The IF is digitized and transformed mathematically into the two quadrature signals, then sent out of the device as a sequence of I and Q samples. These samples are nearly perfect in balance without the hump at zero frequency, which was notable on E based devices.
As an HF radio, it digitizes the entire spectrum up through about 32 MHz. Thence, a flood of data is sent to the host computer for processing. ADC pins 1 and 2 are fed with the output of a transformer arrangement. The input side of the transformer is connected to a suitable antenna.
Such a circuit provides sensitive reception up to around 7 MHz. There has also been work on the software drivers to allow direct sampling the HF spectrum. The results are fair, but limited due to limits inherent in the dongles' design.
The modified RTL code enables reception up to Newer devices with the RT2 tuners may offer more complete coverage of HF frequencies with good sensitivity. A very good surface mount upconverter has been created by Marty, KN0CK , which is small enough to fit inside the dongle enclosure. Opendous, with open source tools, created a high performance upconverter.
These Ham it Up devices can be built from kits or purchased fully assembled from a number of suppliers. Give more thought to using common mode chokes to get rid of much of the electronic noise covering up the weak signals. If you don't do this, you will miss a lot of activity on the bands. The problem is not unique and is faced to varying degrees on other computerized radio or audio equipment. A combination of large values and smaller ones is best, for example 47 uf in parallel with.
In addition, several ferrite beads should be used along with running a few turns of cable on a large ferrite choke. Here is information on the USB connector pins and color codes:. Intermodulation with other strong signals can pollute a great deal of spectrum unless the strongest stations are notched with an effective filter.
One simple filtering method is to connect a quarter wave coaxial cable to the antenna feedline, using a T connector. Keep the far end of the quarter wave coaxial stub open not shorted , and it notches out signals around its design frequency. The filter works well. There have been instances of this kind of coaxial stub being soldered crudely to the receiver input, with the offending broadcaster dropping 20 dB and no longer causing intermodulation problems.
Very deep notches can be made by using two or three stubs. Users of RTL-SDRs are getting top receive performance by adopting a client - server SDR architecture This refers, in practice, to remotely mounting the radio at the antenna, where it is connected to a microcomputer , which functions as a remote server. Long and lossy coaxial cable runs are eliminated this way. Instead, a long run of ethernet cable is used to provide power and carry data.
In fact, the ethernet cable isn't required: one can link to the remote receiver via a broadband Client - server architecture is a very good thing indeed, because it makes the receiver available to any user on the network. Quite a bit of development is going on, and it is a good thing to see advanced software coders creating fresh software for RTL-SDRs that works great. In fact, it uses slightly modified rtl-sdr library that makes better use of the hardware. It is quite a powerful software package, with countless ways to tweak and adjust an SDR to bring in elusive signals.
Pre-compiled packages are available for download as is the CubicSDR source code. Read more about CubicSDR and how to install it from source code with a simple script.
