Excellent SDR with parts
Nave used many many RTL and RTL clones. Running also a openwebrx server. I was not sure with V4 of RTL-SDR Blog. ON linux,, Debian wit ham radio "flair" it was just plug and play. All software running without issue and without the need of changing direct sampling settings. All the way..The included antenna is not bad! Nice and useful. Ease to use, value for money, standard size. I liked it very much.

Great, high quality SDR, good value for money
This product is a great SDR for beginners, with a lot of resources and help available online. After a short installation of the required drivers and software, everything worked smoothly (on a Windows PC). Its compact size, alongside the telescopic antennas, makes it suitable in many scenarios. The packaging was very good, and all parts are of high quality. It comes with several mounts for the antennas, which is awesome and enables me to use it on different occasions at different settings. To sum it up, a high-quality product, easy to use, and versatile. Easily a strong recommendation.

Fun! Avoid on amd pcs
I absolutely love the dongle for listening to the local emergency services. The sticky cup works extremely well. Some major things to know though: -this will not work with some AMD processors. It does not work with any of my AMD processors. It acts like it works , but it's constantly failing/flaky/glitchy. I tried all the different USB powered hub blah blah blah configurations. But nope, moving them to intel machines made all the difference. Super reliable on the Intel machines - even the ones that are old. - windows updates will sometimes update the driver disabling it. So you have to use a program to reinstall the driver. Very annoying since Windows 11 requires you to allow updates at least once a month. -The usb end of the dongles is also fragile, and can lose signal if they're jiggled . So putting them on a hub where they are upright is best. Or in an upright USB port on your computer works too. -They get pretty warm, so you're probably not going to want to put them next to each other. -Having one V3 and V4 works better than two of the same kind. Then you don't have to go into the settings and rename it with a special program. And they just work better together. I use sdrtrunk on pc and trunkrecorder on a potato - works great on both. Better signal than my bearcat. Was easy to set up to upload to openmhz and broadcastify.

Excellent value, minor flaws
It works, there is a design flaw however, an internal spur at 28.8MHz from its TXCO which appears in SDR software, like SDR++ and GNU Radio. Also it seems FM signals overloads the front-end, I could hear FM radio around 29.165MHz and 30.606MHz. I could even tune to out of range frequencies to see WiFi and additional cellular frequencies due to aliasing (indirect samples). Seems like the front-end may not be well designed against strong signals, however it doesn’t affect its what I need it to do, poke around. It does get hot if used for a long time, so be careful. Works great with my Mac, plug it in and run the software either GUI or command line (like using rtl_power) and it works, however it only is interfaced doing one thing at a time, if you want to analyze a signal’s power using the command line tool rtl_power, you have to stop its usage in the SDR software then run the command, not annoying at all, expected. Very, very compatible, although SDR++ is pretty much where it’s at, GNU radio is dated and too complex, with some bugs here and there. Great little device here with minor design flaws.

Excellent starting Software Defined Radio dongle
An excellent software defined radio (SDR) receive only dongle, at a very good price. It is performing very well in monitoring signals in the 10 MHz range. The install, as described in the online quickstart guide, is relatively straightforward, but it is not for the complete novice. There are multiple steps and the behavior of some of the step may vary somewhat from the specifics given in the quickstart guide (e.g. the replace drivers button for zdiag as described in the quickstart was an install button for me). The small dipole antenna in the kit will perhaps get you started, but has relatively low performance. A better antenna, perhaps such s the MLS-30A active loop is probably preferable. But a very nice dongle SDR for learning how to play with software defined radios!

Highly Recommended!
I found this SDR kit to be an excellent choice for beginners looking to explore software-defined radio. It works exactly as advertised, and the bundled antenna makes setup quick and easy while providing decent reception across FM, VHF, and UHF frequencies. The included suction cup and tripod have been incredibly useful for positioning the antenna on glass windows or poles to optimize signal reception. I live in an area where buildings are tightly packed side by side, and the units have no balcony, yet I was still able to receive good signals even with the antenna installed inside my unit. This has made the setup incredibly convenient, especially for those in similar living conditions. I’ve tested this unit on Windows, Mac, and Linux machines, and it performed exceptionally well on all three platforms. Overall, I highly recommend this affordable SDR dongle to anyone interested in getting started with SDR.

I find great value in my RTL-SDR Blog receiver, no disappointment with this quality hardware!
I bought RTL-SDR Blog receiver as an affordable intro to Software Defined Radio. - In my exploration of the hardware, I find capable electronics in a quality metal enclosure, for under $100 including antenna kit. This appeals to my sense of frugality as I can begin learning SDR basics with the affordable RTL-SDR Blog receiver. Affordability makes this receiver ideal for beginners learning SDR hardware and software. I recommend the kit antenna, which is worth the extra expense to quickly get started receiving signal. Also, the telescoping dipole antenna design makes it easy to adjust the length of the antenna to better receive specific frequencies. From my experience so far, I do recommend the RTL-SDR Blog receiver to novices entering the hobby, as well as anyone seeking affordable intro SDR equipment. This SDR receiver will likely require some time to learn the basics and configure to your needs. It is not something that is 'plug-&-play' as much as hardware that requires proper installation, and configuration for specific purposes. Buy the RTL-SDR Blog receiver to get started on an SDR learning journey, but expect to invest time learning some necessary basics before use. I find this device a good deal for learning to use current SDR hardware and software. - As an absolute novice, I invested in the RTL-SDR Blog receiver to learn as much as I can about SDR. I chose this as an affordable way to begin learning, and discovered an enthusiastic community of users. This SDR device seems enormously popular with the amateur hobbyist community, with active forums, topical video and web sites. SDR hardware is not 'plug-&-play,' so realistically, expect to invest some time into learning basic setup, device drivers, software configuration. If approached with patience and curiosity, this device is an ideal first SDR. The antenna kit is convenient, and worth the extra cost. I had the antenna assembled, mounted, and attached to the RTL-SDR Blog receiver in less than 10 minutes. I recommend the RTL-SDR Blog receiver to amateurs, hobbyists, and others interested in affordable SDR learning. It is not a, 'plug-&-play' device so expect to invest time in learning hardware, software, and exploration of SDR in general. I have found the hardware is simple to attach to my PC, however software can present learning challenges and opportunities for the curious.

Everything worked great

Great Product
This RTL-SDR works as advertised, and is genuine, despite what other comments may suggest. (You can check the RTL-SDR website for what makes one genuine, and for me, it checked all the boxes.) It works great with several common SDR applications such as SDR++. If you want an RTL-SDR V4, then this is the one to get, just note that you will need to buy a better antenna, as the ones provided aren't the greatest.

古いドライバーが悪さをするので注意
ラズパイでADSBの受信を無事行えました。 V4は新しくてドライバの設定に手こずりました。 普通にインストールすると旧ドライバーが悪さをするのでご注意ください。 (エラーが無く一見動作している様に見えますが全く受信しません) 受信しない場合は、旧ドライバーを削除もしくは上書きして使いましょう。

Den fungerar. 😊
Den lilla mottagaren fungerar och var inte allt för svår att installera på min laptop med Windows 10. Man behöver dock ha programvara för att kunna packa upp .zip fil. Jag har inte hunnit kolla alla frekvensband men det gick bra att lyssna på VHF AM flygradio och FM rundradio musik och nyheter.
