V3 R860 RTL2832U 1PPM TCXO HF Bias Tee SMA Software Defined Radio with Dipole Antenna Kit

I am not new to Radios, I knew what I was getting into. I know that prior to year 2012, A Software Defined Radio (SDR) such as this one reviewed here were certainly not for general public, as they were considerably more expensive. In the last few years however there have been a ton of development activity in the field of Software Defined Radio (SDR), soon after it was discovered that a un-seemingly simple "DVB-T" dongles based on the Realtek RTL2832U can be used as a cheap SDR. Since that Realtek branded chip allowed transferring the raw "I/Q" samples to the host, which was used for DAB/DAB+/FM demodulation based on the Realtek RTL2832U chip now could also be dialed into frequencies well outside their advertised ranges. Thus, what was designed and sold as a simple device for watching "Digital TV" on your computer could now be turned into a full fledged "radio" capable of receiving frequencies anything between 64 MHz to 1700 MHz with free open source software. Fast forward few years more into development, This current RTL-SDR Blog Version [V3] R820T2, RTL2832U with 1PPM Temperature compensated crystal oscillator [TCXO] & HF Bias Tee for providing power to Low noise Amplifier, Software Defined Radio dongle can now tune from "500 kHz" (Medium Wave (MW) & Long Wave (LW) Radio) up-to 1.7 GHz and upwards. The dongle has up to 3.2 MHz of instantaneous scannable bandwidth while "2.4 MHz" being the most stable on most computers. The RTL-SDR project has become the Radio tinkerer's “first step” for someone looking to experiment with radios. It’s cheap, it’s easy, and since the hardware is incapable of transmission, you don’t have to worry about having a HAM radio license to use it. You can however listen to, decode and scan all the frequencies (Works as an excellent frequency scanner) by pairing with capable software on most personal computers. The official software called as "SDR sharp" from "Airspy" is free and there are also several other capable SDR software one can use with the dongle (Like cross platform SDR++) which passionate developers have been making for the community. Installing the software for using RTL-SDR Blog Version [V3] USB dongle while might be relatively simple for tech savvy persons still remains mostly complicated for average user, that certainly needs to be addressed going forward. Especially the manual method of injecting the right USB drivers using a third party "Zadig" software and relying on various add-on libraries and Microsoft .NET 5.0 32-bit redistributable installed to use SDRSharp. Thankfully, there are other several developers who have taken this to next level by having the whole package preconfigured and ready to use using UBUNTU (LINUX based) .. Check out "Dragon OS". DragonOS which is a Debian Linux based operating system that comes with many open source software defined radio programs & additional decoding software pre-installed that takes all that driver installation requirements seen on windows based PCs totally seamless. Also, I found out that same DragonOS can be installed "alongside" windows if needed for a much seamless operation. Or you can just create a non-persistent "liveCD" environment using DragonOS and boot off USB stick to test it out. Bottom-line: The product reviewed here is an excellent value package, reasonably priced and has all the necessary accessories to get you started into Software Defined Radio (SDR) world. In my humble opinion it is worth more than 5 stars.. Five stars rating. Happy scanning!

I won't repeat what the other reviewers have generally said but focus on some bullet points on its HF capabilities. - Overall, very good HF reception, given its price. An inexpensive introduction to the SDR HF world and see if you want to invest more money and time in this aspect of the radio hobby. - The RTL-SDR is running just slightly warm when using it on HF - Based on using the RTL-SDR with the free program SDR#; was easy to download, install and run on my Windows 10 laptop PC. Go to the RTL-SDR web site for instructions and lots of related information. - SDR# has many options to tweak the received signals. Takes a little time to experiment and zero in on the best settings. - I'm in a typical medium sized city suburb with local AM and FM radio stations. An AMBCB filter was used to keep the local AMBCB out of much of the HF spectrum. A similar FM trap filter (which I do not have) would no doubt tame down the FM spurs that I see in the VHF signals. But the FM spurs do not show up in the HF band. - A decent HF antenna is a must .. I'm using a 40 year old HyGain trap vertical with signal strengths in the same ballpark as my Yaesu FT450D using an OCF dipole antenna. The small whip antennas included with the RTL-SDR are pretty much not worthwhile with HF signals - Tuning hams and other SSB signals is straightforward and gives good results. - For shortwave broadcaster reception, a $50 radio will give improved results. For SSB reception, a $100 radio will be better. I'm referring to general sensitivity, selectivity, audio quality and ease of use. - But the SDR-RTL does show the HF spectrum and its simple to scan around looking for various broadcast stations, hams, utilities, etc. In viewing the HF spectrum, many signals popup and then are gone. A conventional radio is more difficult to find these sporadic signals. - Lots of room to experiment. I may eventually buy a Ham It Up upconverter or an SDRPlay RSP1 or RSP2, etc. which will give improved results. - An excellent value .. recommended 5/14/17 Here is a screen shot (from the program SDR Console) of the RTL-SDR on the 40 meter Amateur Radio band on Sunday night. Lots of signals! Here I'm using the SDR as a 'panadapter' for my Yaesu FT450D ham transceiver. The program supports two way frequency synchronization with the FT450D .. meaning I can tune either the SDR or the FT450D and the other tracks the tuning. Neat!

I have read some of the comments about RTL dongles. The main complaint is their lack of sensitivity and the heat they throw off. In both cases, this is true. The heat issue is is basically a mechanical one. There simply is not enough surface area for these dongles to radiate the heat generated by these devices. As for the sensitivity, these are $20 devices. They are good enough to see if you would interested in continuing to learn more. These are not high performance receivers. That said, even with the antenna provided, inside in a rather RF noisy environment, I was able to pick up a wide variety of signals including airplanes, FM broadcast stations (which even my entertainment receiver WITH an antenna struggled to receive), and Amateur radio operators. I bet if I strung an antenna- or basically just dropped a wire out the window, I would pick up a lot more. The only other issue I have with the device is image rejection. It is possible to find an FM broadcast in several places in the spectrum. I believe these to be spurious images produced by the digital processing of the signals by the dongle. I did drop the rating because it's an OK receiver. You will get your money's worth. It is a fun diversion. I bought it because I am getting back into amateur radio and I wanted to learn a bit more about SDR as I will need some new equipment and I may want to go the route of SDR transceivers. Since I started with this device I have picked up an SDRPlay RSP-1A unit which has more sensitivity and better image rejection. The main difference is the RTL-SDR has only 8-bit wide processing while the SDRPlay has 14. Also, it has wider frequency coverage. So, if you want to investigate what SDR is about, this is a good way to start.

Conocía el producto y quería evaluarlo. Es el mismo producto SDR de RTL-SDR que en su versión "plateada" pero revisionado, certificado y con una carcasa metálica en negro. De lo mejor si te quieres adentrar en el mundo del SDR. Pero no le puedo dar cinco estrellas porque el producto está excesivamente inflado de precio. Por la mitad del mismo se puede adquirir en otros lados incluida distribución nacional y en menos de 24 horas.

Reste à tester la clé avec le programme adapté. J'espère un résultat par rappirt à d'autres clés sdr.
