If you look at the product photo there is a prominent URL listed. I suggest visiting it before buying the product, because this Quick Start Guide will explain what's necessary in order to install the software that makes this thing work. It was fairly straightforward, as I avoided the mistake I made installing it for my V3 dongle back in the day. But just be aware the technical level needed.I chose the suggested SDR Sharp software (which is no cost).While I haven't done side by side comparisons, I get the impression that the V4 dongle is more sensitive than the V3. There is a long list of other improvements, particularly filters and isolation to prevent interference from strong local signals.I bought just the Dongle Only since I already have all the antenna accessories from my prior V3 dongle; however, I never ended up using them. Better, I found, is an antenna such as the MLA-30+ or a long wire.I installed it both for my Windows 10 tablet and Windows 11 desktop.

Works as expected, super useful to get into SDR, not huge change from previous version that I've noticed.

man sollte keine Wunder erwarten. SW habe ich damit so gut wie garnicht empfangen können. FM und DAB+ sehr gut mit Verstärker bzw. aktiver Antenne. RTL_433 habe ich noch nicht ausprobiert. Navtex und Wetterfax, davon war garnichts zu sehen, darauf hatte ich spekuliert. GPS und Satelliten werde ich noch schauen ob da ein Empfang zu bewerkstelligen ist. DCF77 wird wohl wirklich aufgrund der Lage der Frequenz ausserhalb des Empfangsbereichs so oder so nicht funktionien. Unter Linux habe ich den Stick noch nicht ausprobiert. Scheint den Foren nach aber zu gehen.Verarbeitung ist gut. Foren und Blogs sind reichlich vorhanden und auch die Treiberinstallation und Nutzung von GQRX ist mit etwas reinlesen gut zu bewerkstelligen.Der SMA-Stecker bedarf noch eines Adapters ggf. Daran sollte man denken, will man gleich damit durchstarten.

I have the older version of this, these things work great for what they are and you will have lots of fun listening to all the different bands. Make sure you have a good antenna.

I found the v4 a substantial improvement over the v3, especially for HF (also known as shortwave) signals. It's also excellent for FM broadcast-band reception, although not as sensitive as my Airspy HF+ Discovery in that it cannot receive a station I enjoy that is 40 miles (64 km) away. The Airspy receiver has no problem hearing that station, but then the Airspy costs almost five times more than the v4. I consider the v4 an outstandingly good value for how little it costs. Also: the v4's two connectors ... to the antenna and to the computer ... work much better than those on the Airspy. A slight jiggle tends to interrupt the Airspy signal, requiring me to restart my SDR++ app, but that doesn't happen with the v4. I have attached small stick-on heat sinks to both sides of it (see photo) since it runs warm and I will be using it outdoors in hot weather.

Funciona muy bien aunque si es muy necesaria una buena antena al exterior,

I've used versions of the RTL-SDR for quite some time now and they're a very good entry point for anyone interested in SDR. This is probably one of the most widely available and supported SDRs with an unnumbered variety of tutorials for getting it set up. I did have to get a replacement for a couple of these when I ran into an issue with what I assume was the power regulation portion of the board. When this happened, the devices showed only static with no signal pickup. However, the replacements have been doing great.

Works quite well, performs great in the hf range, and the vhf/uhf bands are good too. Worked with the software I have tried it with ( it does require an updated driver but most of what I have is already equipped. ) Price is good, is the original item, not a clone. Recommended

Probado tres o cuatro veces con el programa SDR SHARP, funciona correctamente. La recepción ya dependerá por completo del tipo, calidad y enclave de la antena que le pongas.

Although it took a few steps (follow their online guide precisely) to get the driver's installed correctly on an older Windows 10 system (finally having to use Zadig to get it done), it works perfectly! Sound quality, sensitivity and flexibility really gives you soooo many option for a wide range of receiving pursuits.I have seen a lot of reviews that trash the receiver because they weren't able to correctly follow directions in installing the new drivers so didn't hear anything. I guarantee you that if you follow their very good directions and recommendations, you will be rewarded by having a great and absolutely endless range of fun listening ahead. Getting SDR systems (especially the wide range of software that supports this receiver) setup can be challenging for beginning listeners, but it's also a wonderful learning experience. Be patient with yourself, and you can have a tremendous monitoring station at an unheard of price value.The built in HF up converter provides a much better HF listening experience than the direct sampling on other brands and previous SDR dongles.Highly recommend this as THE BEST way to enjoy radio listening cross a huge variety of useful spectrums.
