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.

have been using this SDR receiver for about one month now and it works OK.. however the antenna that came with the unit had the wrong connector and would not plug into the unit. I had an older antenna that worked well.. currently using this for ADSB with a PIAWARE software running on a RasberryPI 2

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.

Plugged the first one in and its USB connector was dead (computer wouldn't read it). Wrote the company (their support was excellent and responsive) who said it was a factory quality issue and that they would refund and replace. Went through the trouble of getting a second one, and that one is recognized by the computer but flickers in and out (computer just repeatedly dings as it discovers, then re-discovers the usb connection). Support stopped responding when that happened. This is going back too. Going to try a different antennae. Bummer. UPDATE - support has gotten back to me and I'm upping to two stars because they really have tried to be responsive. Here's their latest advice: Also unlikely, as every unit is individually tested post-production. Again, it is possible of course--it's just unlikely. SDRs are especially sensitive to USB voltage issues and transients compared to non-RF USB devices. My best guess is there is an issue with the voltage regulator on your USB hub/controller. We've seen it on occasion. This would cause damage that matches the symptoms described for both units, in fact. Unfortunately those types of issues are usually transient, which means you probably would be able to catch it easily with a multimeter. You'd probably have to monitor the voltage with an oscilloscope for a while and hope to catch it if it is not consistent. Thank you for your feedback, we will be sure to test the devices accordingly when we receive them back from Amazon. If I were you, I'd consider adding a cheap USB card to your PC and using those ports instead :) Better to be safe than accidentally break your new SDR or, even worse, any more expensive devices you may happen to plug in in the future. If we can help with anything else please let us know, otherwise have a great weekend!

Very cool and potentially useful receiver at a great price. I've used it a few times and if you are knew there will be a slight learning curve that you will need to be patient with regarding radio frequencies and the program itself but it is very cool to work with. Recommend downloading the frequencies for the area you are in before starting. You will need to convert them to put them into the program correctly.

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.

Kollade om jag kunde läsa av radiokoder till diverse fjärrkontroller.
