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.

Worked well, but had a huge amount of drift (~80 PPM). After 9 years of use I finally retired this SDR because the huge drift settings caused issues in newer programs that lacked auto PPM correction.

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.

It was a good cheap first step into RTL-SDR, but the device definitely overheats at ambient temps around 84 degrees (nearby temp sensor). No operating temperature specifications listed anywhere (amazon or nooelec site) so who knows it that's within spec, but I wish I'd spent a little more on another device.

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.

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

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.

If you are a tech nerd, then this is your thing! So much fine tuning, possibilities and stuff to explore. Just follow the instructions for this device on the Nooelec website and you are good to go. I do receive my FM music stations with great quality and I also receive the communication of the towers of the Airport nearby (20km). However, I did spent an extra 11 euro to a 'simple to attach and use' antenna. Check it out, it is the XHDATA AN-80 FM SW, which you can also buy on Amazon. Connect (clip on) it to your out-of-the box antenna (that came with the device) and connect the other side to the curtain rail before your window. That side you can also just clip on. Now you have a much better antenna and it makes all the difference! I use the easy to use (after some playing and Youtube watching) software SDR++, and I downloaded the beta (nightly built) version. It is important you use that one! Get in on the sdrpp.org website. It works great and after some time you learn how to master it as a pro :) Again, read the instructions on the Nooelec website. Also refer to the SDR++ manual, which you can download from the SDR++ website. In order to improve the quality of the FM radio stations, I enabled RTL AGC but left Tuner AGC disabled. I manually set the Gain to 40.2 dB. I also enabled IF Noise Reduction. Last but not least, I set the bandwidth for each stations to 200Khz. Each station can be stored in the Frequency Manager for quick access. This all together (and combined with the XHDATA AN-80 FM SW antenne) delivers more signal and sound quality then any of the radio receivers I have. And all of this while I sit inside behind a desk, between walls and 4 meters from the window. PS: On your first usage, after installing the driver. Select (under source in the sidebar) your device and set the sample rate to 2.4Mhz. Don't forget to press PLAY in the upper left corner and make sure you have Radio enabled in the sidebar and Squelch disabled (on start). Then you will hear a sound (noise). Now type in a FM radio station (put the mouse on the left digit of the frequency) and when entered, you will see it's working. Also be aware that you can not zoom out the display more then 2.4Mhz. This is the limitation of the device as it samples 2.4Mhz a time, like almost all of these devices. So, just scroll left or right to explore all frequencies.
