Nice included kit pieces to get started and try it out. Obviously needs longer, bigger antenna to start getting serious but upon first install was able to get AM/FM and FM-HD stations around Atlanta. Got a few other close bands but need bigger (and outdoor) antenna to make it happy. Get and burn the PiSDR-Image, makes it very simple for RPi use. (Pi4 or higher recommended)

Great idea and if it worked better it would be awesome. Wouldn't work with airspy or SDR++ but got it to work with SDR console software. I live in the country and it isn't very sensitive. Probably need a good external antenna. Also make certain your PC has every possible update or it won't work. It's cheap tho

The RTL-SDR Blog V4 comes highly rated from a number of sources on-line and for good reason. It is a very versatile SDR, supported by most available SDR software. The antenna accessories work well too.You may want two of these to work with SDRTrunk.

I really like this radio. The software is very buggy but it's free and it just works. I had a problem on a mini PC with Bluetooth stopped working and had to reinstall WIndows 11. Not a problem with the dongle just a driver issue. There are no clear instructions on how to make this work. A few youtube videos but overall this is the best value for anyone interested in HAM Radio, I also use it for FM radio in my home office.

Der RTL-SDR Blog V4 ist einfach fantastisch! Dieser SDR-Stick hat meine Erwartungen bei Weitem übertroffen. Der Empfangsbereich von 500 kHz bis 1,766 GHz macht es unglaublich spannend, das elektromagnetische Spektrum zu erforschen und herauszufinden, was alles um einen herum „durch die Luft schwirrt“. Besonders beeindruckend finde ich den integrierten HF-Upconverter, der den Empfang im Kurzwellenbereich deutlich verbessert, und die softwaregesteuerte Bias-Tee-Funktion, die externe Antennen mühelos versorgt.Die Verarbeitung ist hochwertig, das Aluminiumgehäuse sieht nicht nur gut aus, sondern hält den Stick auch angenehm kühl. Egal ob Flugfunk, Amateurfunk oder andere Signale – der V4 macht einfach Spaß und eröffnet unendlich viele Möglichkeiten. Für alle, die sich für Funktechnik begeistern, ist dieser Stick ein absolutes Muss!

If you’re buying this then you probably know what you want but in a nutshell this single works well with almost all operating systems and SDR applications. I was impressed with the included accessories. Easy to set up. Good value for money. Stays fairly cool during operation with its metal casing. Good reception, better than my handheld scanner in the same location.

Set up a bit. I am rusty on PC skills, first use of Win11. Did exactly as the user guide said, and had it working as intended. Nice kit. Everything to get started. Downloads from matched, trusted sources. I am a Tech level amateur operator so have some basic understanding. No excess heat from the " dongle".
