Looking for SDR that...

Hey RR,

I bought an SDR recently and the SDR and the antennas were complete junk. The SDR worked the same with or without the antenna. It was the NooElec RTL2832U.

I am looking for an affordable SDR that can run 24/7/364, it just needs to stay on one frequency(UHF Part-90 frequency). Another problem I had with the previous SDR that I bought is that the SDR itself failed to firmly stay in the USB ports it was placed in.

I was disappointed with the NooElec, hope to find one that is satisfactory.

Regards,
Kyle

Sorry to hear about your problem, but I agree that the antenna supplied, if it was one of those small telescoping antennas, is minimally useful. Most dongles come packaged with one of these antennas that are either mag mount or have a suction cup. You'll get much better results with an outdoor antenna. I have dealt with Nooelec before and always was satisfied with their products.

SDRPlayer's recommendation I wholly concur with, those are excellent dongles, just make sure you get the latest revision as there may be older ones for sale. Hope you get things up and running.

Generally, most NooElec SDR are reasonably good. But generally, most people do not know how to use the software as there is no good guide and the default settings are not good. You did not say what software you used and it would be a good thing to know. Personally, for many people (but depends on your personal goals), should buy an SDRPlay (but the initial installation can be confusing) and run initially HDSDR or for those wanting more versatile software and more technically skilled buy an AirSpy and run SDRSharp (though with the .dll, they can run HDSDR). These will cost about $100 more but perform better. I own the cheap dongles for software that needs them but also have AirSpys and SDRPlays. Yes, the antennas provided are poor but you are really buying an SDR radio, the antennas (if included)are just being thrown in.

I also agree with recommending the RTL-SDR dongle. I picked one of these up a month ago & the supplied antennas we're useless, but once I got it connected to my outside antennas I can listen to anything I want to. Mine is connected to a simple long wire antenna for HF and to a discone for everything higher than 25MHz.

I also use rtl-sdr v3 and I think they are great. I use one with a ham it up converter. Using a usb extension cord will help with staying plugged in. I use another 2 with unitrunker. They don’t drift and pick up more stuff than I thought possible.

I've never bought a nooelec bundled with anything else (perhaps the UK market works in a different way).
Fully agree with NF2G :)
I've never had a problem with any of the nooelec dongles I own (about 20) and on the one occasion I spoke to the tech people it was about a possible new item and they were positive and communicative. As for falling out of the USB socket...never had that happen (but I have with an rtl-sdr.com one due to it's longer 'plug' - it wasn't an issue, just a one off).
As mentioned I do also have rtl-sdr.com dongles (two v3's) and have found those and the nooelec equal in performance.
I even have a few of the cheapo originals left from a batch I bought for around $2 each several years ago. Still perform OK and the drift isn't too much of a problem if you know about it.

Big jump in price and I have a couple of Airspy R2s...they are certainly better than the cheaper ones but are they worth the money...18 months ago perhaps, now I wouldn't say so......
Most of the above are in use 24/7 and I've never had one fail.

I happen to like SDRplay devices (maybe I like British in the way that a lot of Americans like to support their domestic market) and would have to say that the RSP1A has to be one of the best value for money devices if you want to take that step up from the $20 point. SDRplay are still producing and supporting them despite adding the RSP2 and RSPduo to their range. In fact the two newer models helped push the price of the 1A down a touch.
A very good P25 trunk tracking set up would be two RSP1As with DSDPlus Fastlane

Whilst not as relevant to the OP (depending which actual device he opted for possibly)
Software is also a nightmare...a wide range of free choices with a whole range of features. Some is a real pain to set up, some is easy. Everyone will have their own favourites (based on what they want to use it for).
SDRSharp - buggy and resource hungry but fairly easy to set up and having a plugin API is a real bonus. (not compatible with all receivers). If you want to use an rtl device as a scanner then this is your best choice currently (by using a third party plugin).
SDRConsole - Slick and easy to use, especially if you have multiple types of receiver. Multiple receivers controlled at once and with multiple VFOs per receiver easy to set up. Compatible with most receiver types
HDSDR - installed it and uninstalled it ten minutes later as it wasn't for me. Many people love it and on screenshots it looks tidy.
SDRuno - very different from everything else. Powerful and very configurable as long as you only want one VFO...more than that and things deteriorate into a horrible mess quickly. Latest version has some scanning functionality.

Antennas...there are very good reasons for them having dedicated parts of this bulletin board but surely you'd want to have something designed for the frequency of interest? If not, just shove some random piece of bellwire in the socket and tape it to the wall.

NooElec makes around 20 USB dongles based on the RTL2832U, so it would be helpful if you would specify exactly which dongle you have.

Their NESDR SMArt SDR dongles are very good quality with a sturdy aluminum housing, and feature a 0.5 ppm TCXO so they will stay locked on frequency with no drift.

I have multiple of both the NooElec NESDR SMArt SDR dongles (black aluminum housing) as well as the RTL-SDR.com dongles (silver aluminum housing), and frankly I prefer the NooElec. The TCXO with the NooElec is slightly better quality, and often times I can leave it at 0 ppm with no drifting, whereas the RTL-SDR.com at times needs to be corrected up to +/- 3 ppm with very minor drift.

I have that one, and that is the one that is failing on me.

I have 4 Nooelec dongles and they all perform well. Either you got a bad one (which happens) or you have a different problem. I can confirm what @GTR8000 said, reach out to Nooelec. I had a bad one and they were very quick to resolve the issue and sent me a no charge replacement. Their cs is outstanding..

I own 7 nooelec tcxo dongles and am happy with them for the price. Performance-wise they don't sample as wide or with as much precision as my airspt mini, but you can get 4 for the price of 1 airspy.

No sdr is going to work well with an inadequate antenna. Sometimes the cheapies are sufficient for strong local signals, but weaker stuff will require more care and attention. Unavoidable really...

Sometimes dongles do go bad and I've experienced this personally. Nooelec was good to me when I had to send some back. Don't write them off because of one bad experience.

By the way,I recommend you use a short usb pigtail do you don't have to plug the dongle directly in to the computer.
