Nooelec RTL-SDR v5 Bundle - NESDR Smart HF/VHF/UHF (100kHz-1.75GHz) Software Defined Radio. Premium RTLSDR w/ 0.5PPM TCXO, SMA Input, Aluminum Enclosure & 3 Antennas. RTL2832U & R820T2-Based Radio

It came with 3 different types of antennas and a magnet extended range mount for the antennas. It also came with a shielded (ferrite choke) USB extension cable that I don't think was listed in the description. But it's very convenient if your USB ports are located on the back of you PC so you don't have the SDR dongle in the back of you PC where it's already hot from the PC exhaust and PSU heat. The unit gets quite warm during use but not uncomfortably hot to touch, nor does it appear to affect it's performance at all. It's has a small profile design that fits my 90° OTG adapter for my tablet with the the tight clearance cause from my tablet case, which is nice. Although if it didnt fit I could have just used the USB extension cable between the OTG adapter and SDR dongle. I'm very happy with this unit! It's a great value for the money.

When I bought this little SDR, I was a bit discouraged by how it took extra work to get it to function on windows. It eventually did and performed well... for a while (both in windows and linux). It had success working with SDR#, HDSDR, GQRX, and I suspect it would have worked with any SDR software. Well, I used it successfully yesterday and had no mishaps storing it as usual, however, today it does not work at all. It didn't last 6 months (more like a week of actual use). I seldom used it until the last two months when I began to learn how much more I could do with a SDR. I have no explanation nor advice on how to avoid this- it just quit working. I have tried (un/re)installing (yes, I know about Zadig). No changes were made to the system it was used on yesterday. It was powered off, then powered on today and it doesn't work anymore. This is NOT an installation or user issue. I have tried it on multiple ports and more than one system, windows, linux, nothing. Before this, I definitely would have given it 5 stars. This makes me a sad panda.Now I get to play the warranty game. I am extremely grateful for the 2-year warranty... now, how to go about starting that?**UPDATE**I spoke with the NooElec support team at: support@nooelec.comI must admit to being a bit surprised. Their response was incredibly fast. In fact, it was almost immediate. It was so late in the night, I didn't bother looking for a response, but it was there, and didn't appear to be a scripted automatic response. Their support was amazing. Even through email, Sarah was quite pleasant and easy to work with. The information I provided seemed uninformative to me, but I gave all the steps I took to troubleshoot, my observations and also the two screenshots I put here (my details were a bit more expansive than what I put here). It was all that was needed to determine what was wrong. In my case, it was not deemed worthy of salvage or further troubleshooting. This is apparently a rare issue as all NooElec stuff is burn-tested for 24 hours. A bad one got through, but that sort of thing inevitably happens to almost everyone's product. I'm not trying to be a commercial, or sound like their PR, lol... just expressing pleasant surprise. A 2 year warranty speaks pretty highly by itself!A replacement is now on the way. Looking forward to it. I wish all warranty support went this easily. If it weren't such an easy process and an experience which also gave me so much confidence in their products, I would have only taken the 1star to a 4star. This went so smoothly and painlessly, it deserves 5 stars. I had been pondering which SDR brand to toy with next after this one broke... but after this warranty support, I will definitely be buying more of these! I am a loyal customer now... and my first one was a dud.If you are shopping for SDRs, get one of these. If it breaks, they'll take care of you.

This is my second NooElec SDR I have purchased and it works well under Ubuntu Linux for twin SDR using sdrtrunk.They get quite hot but the aluminum case seems to to the job. My first one has lasted well.

The Nooelec RTL-SDR hardware works really well for RF monitoring and experimentation. I’ve bought three so far and they all work great. Very nice and premium-feeling aluminum outer case. Everything was nicely packaged. I’ve run these sticks on a Raspberry Pi for days at a time doing trunked scanning with no frequency drift. They all worked with zero or minimal ppm correction needed. If you want some RTL-SDR hardware this is a great option. It’s not perfect, though.While it is technically true that you can run two side by side on a Raspberry Pi, in practice I didn’t find this to be very practical. It will cover all four ports so forget about any other peripherals. When run in this configuration, the two SDRs will get really, really hot. With a little extra separation, they get warm but not hot. (I realize these are designed to run hot, but why do that if you don’t have to?) Even though you can run two side by side on a Pi, you’re better off using a USB hub instead in my opinion.The other problem I’ve found is something about the USB-A connector design doesn’t allow them to make a great connection with the host. I’ve tried multiple USB hubs, and of course connected directly to the Pi and in every case the dongles don’t feel like they are held solidly in place. They are quite loose and slightest bump will disconnect them or give a lousy connection to the host until they are wiggled around some to reseat them. This doesn’t appear to be a problem with the USB connector to the RTL board, it’s something with the connector design and how it mates with the ports — almost as if it’s slightly too long. If you plan on using these with a semi-permanent configuration, you should consider a bit of hot glue or epoxy to make sure they are held in place even if bumped around. I’ve had no problems with the SMA connectors and they feel solidly attached.The antenna kit is basically junk and its only saving grace is that it doesn’t add much to the unit price. I bought two NESDR + antenna kits, and both are kind of broken. One of the magnetic bases fell apart on me after a few uses, and the other has a loose internal wire that will need soldering to repair. The magnetic mount just had a threaded post that you screw the antenna on to rather than something like a SMA or BNC connector, so neither the base or antennae can really be used with other things. You will absolutely want to buy a better antenna for your use case once you get beyond basic experimentation, but this kit is fine simply to get you off the ground.So, in all it’s great hardware let down by a couple unfortunate but not insurmountable design decisions. As long as you keep these things in mind when you purchase, you’ll be fine.Update:I’ve been running these 24/7 for a few months months doing trunk scanning on my local emergency services and uploading the feeds to Broadcastify and OpenMHz.I have the SDRs plugged in a vertical USB hub with foam mounting tape to keep them held in place so little bumps don’t cause them to disconnect. There is about 1/2 inch separation between the SDRs in the USB hub and they barely get warm to the touch even after running for weeks at a time at 20dB gain.They are connected via a splitter to a Nooelec LNA which is connected to a Remtronix 820S antenna. The trunk system I use is analog, and recordings are crystal clear. It’s been rock solid.My opinions remain unchanged from before: solid and reliable hardware only let down by some unfortunate design decisions.
