Re: SDR# not recognising USB stick

Did you follow the quickstart guide? www.rtl-sdr.com/qsg

In newer versions the install procedure changed slightly. You need to run the install-rtlsdr.bat file.

Re: Help with my first RTL-SDR setup

Hello! I have recently been learning about SDR and I am very interested in purchasing my own RTL-SDR setup. However, I have a few questions that I would like to ask you guys before I make any purchases. I have decided to spend ~$100 on a setup, and I think I would like to buy a dongle from this web...

Re: Would T-bias benefit from LC filter?

What frequencies are you listening to? There is some HF noise generated by the switching regulator in the dongle. There is already an inductor on the bias tee to block signals from getting through to the power rails, but lumping in more inductors might help. Also ferrite beads.

Re: NooElec R820T is it good?

The included antennas should be good enough for GSM, it doesn't need to be perfectly tuned for those strong signals.

Re: NooElec R820T is it good?

There are several antennas for 1800 MHz since that is a popular cellular phone frequency. If you just type 1800 MHz antenna into eBay you'll find many options http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.X1800+MHz+antenna.TRS0&_nkw=1800+MHz+antenna&_sacat=0. Just ...

Re: NooElec R820T is it good?

1.8 GHz? E4000 dongles can go up to about 2 Ghz, but if you're going to spend that much then probably better to go for the SDRplay which can go up to 2 GHz. Other than that the HackRF is the next low priced unit that can go up to 6 GHz. On the cheap you can look into building or modding a downconver...

Re: Power scan with a graphical plug-in

The only plugin type software I can think of that might help is the Scanner Metrics plugin at http://www.freqmgrsuite.com/. Have a look at our plugin list at http://www.rtl-sdr.com/sdrsharp-plugins/, and you might see something else. Other than that, you'd need to script something with rtl_power, or...

Re: RTL-SDR dump1090 windows

Have a look at the note I made under dump1090 on the tutorial I wrote here http://www.rtl-sdr.com/adsb-aircraft-ra ... h-rtl-sdr/.

I'm not sure if this is still unfixed, or if there is a newer branch that fixes it, but it sounds like your problem.

Re: SDR byBA5SBA

Yeah if its showing up on many frequencies then the AM band is overloading and when that happens the original station can show up on other frequencies too, while making the sensitivity for other stations very bad. Usually not a major problem with an upconverter as you can simply turn down the gain, ...

Re: SDR byBA5SBA

It sounds like it's working properly if you can receive AM radio. By reapting themselves, do you mean that you see them at multiple frequencies? One thing to note is that the HF performance on those units is not great, but should be enough for most decently strong signals. But there are a few possib...
