Nooelec NESDR Mini 2 USB RTL-SDR and ADS-B Receiver Set, RTL2832U and R820T2 Tuner, MCX Input. Low-Cost Software Defined Radio Compatible with Many SDR Software Packages, ESD-Safe

Device comes in a plastic bag with no documentation, and no software. I had to search the internet until I found www.RTL-SDR.com/rtl-sdr-quick-start-guide/ This answered all my questions and got me up and running. The www.nooelec.com website has links to SDR# and HDSDR software for windows. Both are fantastic programs for listening to various types of signals from 25Mhz up to 1750Mhz. I've been listening to CB radio, FM broadcasts, Fire, Police, Airlines going overhead, and the 2 meter and 440Mhz Ham bands. Interesting thing, when I listen to the Ham bands on a regular Shortwave, I hear the signal about 1 or 2 seconds before I hear it on the RTL-SDR receiver. Must be some kind of lag as the computer processes everything. If you have a Mac, the software works fine under Parallels, however there is a free Mac software for it called GQRX. It works, but is very limited. My favorite is "SDR-Radio v2" I asked Tech Support at NooElec about the Remote Control that comes in the package: It's not for any of the SDR apps, it's for DVB video, which is aTV format that's not transmitted here in the US. If you're in Europe, here's the link to the software: http://f.nooelec.com/TV28Tv2.iso Here's some software tips, in case you get these errors: Program name: SDR-Radio: Error was: “Cannot gain exclusive access to the selected radio.” Solution: Turned out that in Windows Task Manager, an occurrence of “SDR Console” was hiding out that didn’t close when the rest of the program closed. Program name: HDSDR : Error was: "A device ID has been used that is out of range for your system." Solution: Turned out that the program had forgotten the sound card it was to use. (RX input from radio, and RX output to speaker.) Should have been Parallels microphone and Parallels speaker, but the program forgot. Program name: SDRsharp: Error was: "1 compatible devices has been found but are all busy." Solution: Once I got those others going, this one was back to normal.

I purchased this USB-connected software-defined radio (SDR) to set up a Raspberry Pi based FlightRadar24 receiver/reporter. The setup was quick and straightforward. Initially, my FR24 rig with the SDR's included antenna placed near a second-story window captured ADS-B position data from around 12 airplanes. Cool, but I wanted more! After experimenting with the antenna's length and setting the antenna on a makeshift ground plane (an aluminum cookie sheet), the transformation was remarkable. Opting for a half-wavelength setup (13.75 cm for 1090 MHz ADS-B signals), strategically placing the antenna near the exterior window, and using my cookie sheet ground plane, the system went from tracking 12 airplanes to an impressive 32, with position data extending up to 95 nautical miles! These adjustments proved crucial, unlocking the full potential of the included antenna. This USB-connected SDR, combined with the provided antenna, does a great job as part of a budget-friendly FlightRadar24 ADS-B rig. Highly recommended for those willing to explore and fine-tune for exceptional performance.

Finally, A Best ADS-TECH Product! (NOTE: I realize now that this is the older product, superceded by the NooElec NESDR Mini 2+ version. These "2" versions have a frequency tuning error of at least 62 PPM, and tends to drift as the unit warms. I have just acquired the "2+" version and will be returning this "2" version.) The design casing gave me a surprise when I first opened the product packaging, and realized this device oddly looks similar to other ADS TECH USB radios. (For which I gave a test run and has been laying in a shoe box for several years now.) But this is the first device, for which I'm finding extremely useful! As with other software defined receiver enthusiasts, I'll be using this hardware for analyzing frequencies. Pros 1) Best bang for your buck. A device allowing users to fully exploit hardware's capabilities, using computer software. 2) Can likely be utilized and extended with up-converters. Cons 1) Difficult to find exactly which software utilities and which drivers you need to using as a computer software defined radio for analyzing frequencies. This product was engineered for use with European DVB-T over-the-air transmissions, but can be utilized within the US for receiving over-the-air FM modulated or other modulated frequencies. 2) No RTL2832 chip specifications are published. (ie. Read forum posts dated approx 2014, read reddit.com forum post, "RTL2832 datasheet / deep info?") 3) Device's tuning crystal is susceptible to temperature fluctuations. As such, users need to constantly recalibrate the device for accurate frequency usage. Easy method is to tune and center to a known strong signal and adjust the device Frequency Correction PPM value to match the signal's commonly known frequency. Adjusting either the device's "Frequency Correction PPM" or "Input Sample Rate" will effect the value of the other's value. Currently my values are Frequency Correction 57.0 PPM & Input Sample Rate 96000Hz or 96k. Another example, Frequency Correction 67 PPM and Input Sample Rate 1,000,000 or 1MHz. Even after entering this correction, since Frequency Correction PPM value does not accept a float values within SDRSharp or GQRX, manual fine tuning is still required except for maybe wide band FM. The more difficult and more accurate method of calibrating or tuning, is using a GSM signal. 4) For most people living outside the city, requires both hardware and tuner AGC to be active, in order to obtain any really usable signal, especially when utilizing digital signals or operating digital speech decoders. (Without hardware and tuner AGC, you'll have some static.) SDSharp (Windows) has both hardware AGC and tuner AGC options, and GQRX has hardware AGC top right menu tick box and a variable tuner(?)/software AGC slider on the bottom right menu. RTL-SDR rtl_fm has a tuner gain (or AGC?) via "-g" option, so being digital to speech decoding requiring a very strong local signal, this is not going to be available to most people except for inner city folks.

This is a fairly standard DVB-T receiver stick that is great as a software-defined radio. I haven't actually used it for DVB-T reception. In my case, I use it for receiving ADS-B signals from aircraft, a job at which it excels. It has a pale blue LED to indicate that it's plugged in (though the LED isn't excessively bright) and a common MCX antenna jack. The included telescopic antenna is of good quality, has a magnetic base, and is suitable for most purposes. It comes with an IR remote control, but I've not used or tested the remote. The one minor drawback is that the stick itself is physically large and, while not heavy, isn't exactly light. I ended up putting a little rubber foot on the end of the stick so it doesn't apply any bending force to the USB jack. It also blocks nearby USB ports due to its size. Alternatively, one could use a short, flexible USB extension cable to address both issues.

I bought this to make a ADS-B receiver for FlightRadar24. It works great! It tracks all the planes in my area and have even used it to listen to the cockpit chatter between the pilot and Air Traffic Control. Getting the correct antenna length was trial and error for me but eventually I found the correct length after I put a pizza pan under the antenna.

After many months usage of the Mini model, hoped this would be an improvement for my ADS-B monitoring. Didn't work quite as well as the older unit. First one received was defective, the base didn't have the threaded rod sticking out. Immediate replacement by vendor, so an A for customer servrice and D- for quality control. This is the Mini 2, not the Mini 2+, which has temperature compensation. If you're looking for an upgrade, wait until those are more commonly available. This comes with telescoping antenna, a good idea for a wide-range receiver like this. But you can't make it short enough to be optimal for 1090 MHz, if you're receiving ADS-B. With the old antennas, it's easy to clip them. So in this environment, the antenna is not an upgrade ether. Fun toy, but the only real improvement is the pastel blue color.

The antenna is quite small, but has pretty good range. I have it sitting inside our basement in a window and I'm getting around 6,000+ ADS-B beacons a day from planes flying overhead. Works out of the box with FlightRadar24's official Raspberry Pi image on a Raspberry Pi 3 B+. For around $30 dollars, you'll net a $300+ business upgrade from them simply by sharing your receiver's data.

I bought this device to get traffic and weather information while flying. The traffic part works great after I followed the instructions at flightradar24.com/dvbt-stick . Flight radar however requires internet connection, so you probably want to download PlanePlotter to your PC. To use it you will need to also download any chart from the FAA site, convert to JPEG, and calibrate it within the software. As for weather, that's much more complicated if at all possible. Traffic is transmitted on 1090 MHz using a certain low bandwidth protocol. That is what you can easily pickup with this product. Weather, as well as traffic, is transmitted on 978 MHz UAT at a much higher bandwidth. It is unclear if this product or any SDR can handle this bandwidth. Some reported some success using a code that is available on the internet, but you will need to compile the code to use it. Bottom line, the product does exactly what it is advertised to do. But if you were hoping to get weather information, it may not be it and in any case you will need to wait until someone develops software for it.

Consegnata nei tempi previsti, la Chiavetta Usb funziona perfettamente e senza problemi per utilizzi come ADS-B, RTL, SDR, e la versione ridisegnata dell'antenna ne rende migliore l'utilizzo, quindi davvero consigliata per gli appassionati.

Purchased for use with Home Assistant and rtl_433 library - works flawlessly and detects all my old alarm sensors perfectly.

Wie erwartet guter Empfang mit der beigelegten Magnetfuß-Stabantenne. Nutze es zuhause unter Win7 für die Überprüfung der Sendeaktiviäten der Sensoren und Aktoren im 433MHz und 866MHz Bereich (eq3 Homermatic etc). Werde mir wohl noch eine Richtantenne basteln. Neben der Ware habe ich noch eine Service-Email erhalten mit ausführlichen bzw hilfreichen Installationshinweisen (Treiber, SDR Konsole). Tolles und günstiges Gerät, welches meine Erwatungen voll erfüllt. Einziger Verbesserungsvorschlag: Das Beifügen eines Adapters (SMA, BNC, etc) zum Anschluss normaler Antennenleitungen wäre noch hilfreich.

Fais ce qu'on lui demande. Documentation à trouver soi-même. Une fois que ça fonctionne, vous pouvez trouver beaucoup d'utilisation à cet appareil.
