Brand new design! The NESDR Nano 2 are custom-made by Nooelec for SDR applications. The enclosure was also re-designed to assist in maintaining lower temperatures than the previous generation.
The tiny size and 24/7 capability makes the Nano 2 perfect for embedded applications! How small? Just 24mm x 21mm x 8mm (15/16" x 13/16" x 5/16")!
The Nano 2 contains a new custom TCXO fabricated exclusively for Nooelec. Important TCXO specifications: Frequency stability: 0.5PPM (max) Phase noise @1kHz offset: -138dBc/Hz (or better) Phase noise @10kHz: -150dBc/Hz (or better) Phase noise @100kHz: -152dBc/Hz (or better) This is, by far, the highest performance TCXO available in any low-cost SDR.
As with other units in the NESDR Plus series, a full 2-year warranty is included at no extra charge. We guarantee antenna protection will be present so that your new investment will not be quickly destroyed by spurious ESD. And, as usual, we perform extensive QA.
The low-ESR NP0/C0G capacitors and high-Q inductors we use for production assist in lowering the noise floor, increase stability and improve longevity.
The NESDR Nano 2 is based on the R820T2 tuner IC made by Rafael Micro, which means an approximate tuning range of 25MHz-1700MHz and improved selectivity and sensitivity in most frequency ranges versus R820T-based SDRs. There is also an RTL2832 (RTL2832U) IC on board of course, to provide basic demodulation and USB interface functionality
Full compatibility with a wide variety of popular SDR software packages, such as Matlab, HDSDR, SDR Touch, Planeplotter, SDR#--too many to list, really. We're talking Windows, Mac, Linux, Android, Raspberry Pi...you'd be hard pressed to find somewhere you can't use these!
The connector type on the antenna and USB board is MCX--male MCX on the antenna, female MCX on the SDR. There are plenty of adapter and adapter cables available in our store if you want to connect your favorite antenna!

Downloaded the latest Zadig file and followed the instructions for installing the drivers. SDR# cannot find the USB after selecting 'Source' and looking for it after I selected the gear icon. The RTL-SDR (USB) does not show up, only my HackRF shows up. I've placed the NESDR Nano 2 Plus device into different ports, and nothing. I used an OTB on my Android using SDRTouch, and the device is recognized. I've tried different YouTube, Reddit, and other instructions but to no avail.Update: The device no longer works.

超低位相ノイズが凄く良かった！最近のSDRには余計な機能が増えて本来の機能を損なってしまっていて、SDRとして意味の無い商品が多数混在する中で素晴らしい物でした。またSDR仲間用に購入します。

I couldn't tell based on the description, but I was psyched to find out that this product picks up 978 MHZ UAT! The weather doesn't work in the Avare app in Alaska without ADSB. Once I got in the sky I started getting weather data and seeing local traffic. What an awesome, affordable alternative to commercial ADSB-in receivers.

Does everything it's supposed to do and for a better price than the others.

Using this to capture utility meter readings with a Raspberry Pi. While it tends to run hot (thermally), its doing what I wanted it for. The included antenna is decent enough for this application and appears to be "good enough" for my needs, however if you have any real distance that might be an issue. For a low-cost solution that SDR is required, the price is right. This seems to be a decent value for what I bought it for.

Picked this up to decode 433Mhz, works like a charm.I can now trigger home automation events based on signals from 433mhz devices, only took about 2hrs to make it work, but that's because I had to debug MQTT a bit. (Remember to add "listener" to your conf!)Here's the chain I'm using.Ubuntu 22.04 -> rtl_433 22.11 [repo] -> mosquitto 2.0.11 [repo] -> mcsMQTT 6.8.2.0 [Homeseer Plugin] -> Homeseer 4.2.16.0

Use this with my Raspberry Pi 4 and Dump1090. Can track all the planes in my area up to 100+ km away. Amazing for such a tiny device.

I bought this based upon some of the other reviews. I needed something small that did not stick out as it was going to be plugged into a Raspberry Pi in a confined space.Reason for buying was to detect a Byron B30141A doorbell being pressed.I wanted the doorbell receiver in the front room for whoever was sitting in there so they could hear it.I also wanted to know when I was at work upstairs when the doorbell had been pressed.As this was just transmitting on 433Mz and a bit, then this rtl-sdr dongle should do the trick.I installed it on a Raspberry Pi running PiOS 64bit.Installed the rtl-sdr, gqrx using apt, downloaded from GitHub merbanan/rtl_433 and compiled.First had to locate (home in on) the frequency, so used the gqrx.Turned that into 433mhz and then watched when I pressed the bell a few times.Blow and behold the signal was just slightly off to the right.Armed with the actual frequency I could tell rtl_433 that and then use it to unpick the PWM signal.I needed up with around 20 versions.Also the bell is known to transmit around 20 difference codes changing at will.So press the bell a few times to see what comes out.Now I have the pwm setup, I use rtl_433 to send an MQTT message onto Node-Red.There I can interrogate the message to see if it really was my doorbell and if so send it on to a Home Assistant notification and to another MQTT topic, which then pings most of my apple devices and my Pc running linux which is hooked into the MQTT topic and Home Assistant.Success it works.

Was quite disappointed at the performance of this device.As a simple test, I connected it to a better all band antenna and tuned to local NOAA station 162.550 MHz. Was not able to receive any signal! Using a UV-5R right next to it varified the NOAA station was clearly receivable.The Nano+ is therefore quite useless and a waste of money.*UpdateHere is an update after working further. It turns out that the Android App "SDRTouch" is what seems to have been the issue. Installed "SDR++" instead which works a lot better. It pulled in the NOAA station which was reported above as undeceivable. One very big thing that makes a difference is SDR++ gain controls. While SDRTouch has a gain control, it doesn't seem to do much, while SDR++ gain controls make the difference.

Works great as ADSB receivers, but I keep having to replace them every couple of years. They run VERY hot, which could be why they don’t last. If you don’t operate them 24/7 they will likely outlast your needs. I love their size which is why I will keep on buying them.

Ich verwende dieses Teil als sehr preiswerten AIS-Empfänger (Automatic Idenfication System) zusammen mit der App "AIS share" und einem OTG-USB-Kabel an einem Android-Tablet. Damit kann ich gängige Navigations-Apps (Navionics, OpenSeamap) mit AIS-Daten versorgen. Funktioniert sehr gut und wird auch nicht übermäßig warm. Es zieht 150mA aus dem Tablet, was durchaus vertretbar ist.Die sehr kleine Antenne mag für einen UKW-Radioempfang ausreichen, für einen brauchbaren AIS-Empfang ist sie zu mickrig, die Reichweite ist mal gerade 2 nautische Meilen. Mit einer größeren Antenne komme ich auf über 10 Seemeilen, das reicht mir völlig.

Have been using the Nano 2+ for a few weeks now, representing my first foray into SDR. I've used radio scanners for many years, and known about SDR just as long, but by the time the rtl-sdr came into the public eye I had stopped keeping up with developments. All I can say is wow! It works great with both my Samsung Galaxy Note 5 using either samsung's own USB OTG adapter, or the Inatek USB 2.0 hub/card reader I also purchased here on amazon, which supplies external power to the Nano2+, reducing battery consumption while monitoring. Unfortunately Samsung has charging disabled while in USB Host mode (even though custom ROMs have enabled it on bootloader unlocked models) so I eventually have to disconnect and charge my phone. This includes Wireless charging. Note that this is no fault of the NESDR at all!I've had nothing but positive experience with it, the TCXO keeps the frequency spot on. I've only ever had to adjust by 1 PPM if ever. The unit does run hot, surprising me the first time I touched it after an extended listening session. But despite the heat, performance is great.On the PC side of things, it works great with both Windows and Linux (I dual boot) - so far everything that carries rtl-sdr support works with it just fine. I'm quite tempted to buy another for tracking trunking systems and the like. My immediate area remains analog but there are plenty of P25 systems in reception range that I wouldn't mind listening to. I haven't yet had a chance to pair it with a better antenna than the stock aerial provided, or test it in an enclosure to keep noise out (my house/area is EMF hell), but hope to soon. Hard to go wrong at the price. Very hard.
