Nooelec NESDR Mini ミニUSB RTL-SDRおよびADS-B受信機セット、RTL2832UおよびR820Tチューナー、MCX入力。 多くのSDRソフトウェアパッケージと互換性のある低コストソフトウェア無線機。 R820Tチューナ

付属のアンテナを使用してADS-B feederを作成しましたが、問題なく受診できています。

ads-bを受信しflightradar24のContributorになりたくて購入。 初号機が故障したので２代目の購入となりました。同封されていたアンテナが短く頼りなかったので、初号機のアンテナをそのまま使用しています。自宅２階の窓際に置いてありますが、問題なくデータを受信しています。今年の夏は気温が暑く熱暴走し初号機が故障しました。熱には注意が必要です。

問題なく接続でき、連続稼働させています。 ケーブルがもう少し長ければ設置の自由度が高まって良かったと感じました。

flightradar24用に購入しました。 Raspberry pi Zero 2 Wに接続して使っています。 窓際の室内でも十分に電波を受信しております。 うちの環境 root@raspberrypi2:/etc# cat debian_version 12.9 root@raspberrypi2:/etc#

UbuntuをインストールしたRaspberry Pi 4に接続し、なんとか設定出来利用できています。

ADS-BのFeederとして利用しています。 熱暴走しているのかもしれませんがたまに受信できなくなることがあります。 気がついたら冷まして再起動すれば問題なく動作します。

機能は問題ないが、USBへのアンテナケーブルが短く、扱いにくい。

SDR#で使用中LEDランプが消えて反応しなくなったので壊れたのかと思い連絡してみたら 色々と症状を聞いてくれて対策を教えて貰い（ドライバ等の場所とか）、また使用できるようになりました。 LEDランプは故障しっぱなしっぽいけど、通常使用できるので問題なしとしました。

I've never been all that interested in radio, or spending any money on it, but when I saw a video describing these $20 RealTek chipset based dongles and how they could be used for SDR and radio spectrograph type applications, I was like "For $20? Count me in!" Like most people I'm using SDR# and not any of the vendor's drivers. The thing that took me a little while to figure out was that the USB drivers for this thing have to be installed manually. (There's absolutely no "plug and play" support for this thing at all, because the driver used by SDR# is a very generic low-level USB driver that is only designed to allow applications to essentially talk directly to just about any USB device supporting some serial protocol.) The easiest way to get this working is to download sdr-install.zip from the SDR# web site, extract it, and run the install script that will download everything you need including zadig (the generic USB driver installer), the RTL chipset plugin for SDR#, and SDR# itself. Before running SDR# you need to run zadig.exe and use it to install the driver. This requires that you select "show all devices" from the Options menu, select your RTL dongle from the pop-up menu, and tell it to install/reinstall the WinUSB driver for that device. Be careful to select your RTL dongle before hitting install or you may accidentally install this over your mouse driver or some other device. (Like I say, this is a generic driver that installs a really basic software interface for any USB device that supports certain attributes, so there's nothing to stop you from overwriting one of the other drivers on your system if you select the wrong device.) Once the WinUSB driver is installed you can just run SDR#, select the RTL device as the input, and hit play. Tip: I'd recommend turning on the auto gain check box for the tuner ("Tuner AGC") in the configuration panel though, unless you want to mess with the manual RF Gain control. (I was able to do pretty well just using the auto gain, but before I enabled the auto gain every signal I was getting was very weak. So you really need some sort of gain adjustment be it manual or auto.) Without much effort and using only the little included antenna I was able to pick up NOAA weather radio (narrowband FM), a number of commercial FM radio stations (wideband FM), the wideband FM transmission from a Sennheiser RS110 926MHz analog wireless headphone transmitter, and see a bunch of other signals on the spectrograph that I didn't recognize. I was also able to pick up 2 or 3 ADS-B transmissions from commercial airplanes, even though I was sitting in my basement and using only the included antenna, though all of these airplanes were within the line of sight angle provided by the window in the room I was in. So this tuner seems to be good for ADS-B, but obviously you're going to need an unobstructed outdoor antenna of some sort to receive signals from all directions. The remote control that comes with the dongle seems to be totally useless since it appears to be an IR device and I don't see how a computer can even receive a signal from it without a separate IR receiver device. (The NooElec dongle doesn't appear to have an IR receiver on it, but I could be wrong.) In any case it would require either the vendor's DTV software or some other software to make any use of it, and I don't know of anyone who's written anything useful that it can be used with. At some point I'll probably buy a MCX to some sort of coax adapter and wire up a proper antenna for it outside, but for now I'm just messing with the cheapo little included antenna. It seems to work better than I expected. Anyway, this is the most interesting $20 gadget that I've bought in a long time. I suspect that one day it will come in handy for helping to locate and rectify sources of radio interference.

Less clear sound and signal quality than I expected compared to a Boofwang K-5Plus, I tried it on VHF and UHF but no real clarity from any of the local repeaters

Este sintonizador RTL-SDR de Nooelec es simplemente increíble! La calidad de recepción es excepcional para su precio y su compatibilidad con una amplia gama de paquetes de software SDR lo convierte en una herramienta versátil para cualquier entusiasta de la radio.

Recomiendo encarecidamente este producto a cualquiera que busque una solución de radio definida por software de alta calidad a un precio asequible.

the OEM antenna out performs a bunch of other larger antennas, i was blown away

Works brilliantly with home assistant - allowed me to pick up my 433mhz weather station using MQTT and feed the sensors directly into my dashboard. No more pesky seperate screen required! The device is fairly compact and just slots into your USB A port, the antena cable is quite short, i personally would have prefered it to be longer so that i could distance it away from the electronics, however you are very limited in distance with the included antenna. The device does get quite warm when left on 24/7 but nothing that would overly concerned me. Home assistant configuration was super easy with the RTL-HAOS add - i did find i needed to sort out the noise ratio with some YAML as the pre set formula didn't work well for me. Apart from that this really is a plug and play device. I am happy with it and would recommend it to others.
