Re: [Discuss-gnuradio] SDR/USRP devices

[Marcus Müller]

the features are not important for me now

Then you can literally buy a rock. It has pretty bad reception, and all receivers built with rocks have a 50% bit error rate. (just kidding)

SDR peripherals are technical equipment. There has to be *some* specification of what you need. Like Bandwidth. Make yourself acquinted with the parameters I listed in my last email, and what they mean. Then you will surely come to some conclusion of what you need.

I just want to simulate a Cognitive Radio without a lot of details

CR doesn't specify what you actually want to do at all, technically.
For simulation you'd not need any hardware at all - so maybe you'd want to specify more closely what you want to do!

Antony asked about this on Ruby Forum

For people finding this later on via Google: This is NOT ruby forum.
Ruby forum is nothing but a *bad* interface to the GNU Radio mailing list archives, which you can find at lists.gnu.org, and an even worse implementation of a mailing list client. You're doing it right by using email to communicate with us!
Also, there's a lot of Mails going through this mailing list, so I don't know which Antony or which email you are referring to.

Best regards,
Marcus

Marcus,

Below $120 is okay for me. Actually, the features are not important for me now, because I just want to simulate a Cognitive Radio without a lot of details. I just wanna see it working to study and learn about this process. Like I said, it's important to have a receiver port and be compatible with Gnuradio.

I saw that Antony asked about this on Ruby Forum (it seems he has the same interests, but no one could help him, so I came here to the mailing list).

Thanks for any help.

Cheers,

Hi Pedro,

You will, as for any device, need to figure out what you need, specification-wise. I'm obviously a bit biased, but no one else might even be able to help you unless you wrote some numbers: frequencies you're interested in, bandwidth you want to sample at once, stability, available interfaces, cost range etc.

Best regards,
Marcus

Hello,

I've been searching a lot about SDR and USRP devices to purchase. All I need is a board with a receiver port (transmitter is not important for now) and it's necessary to be compatible with Gnuradio. There are some options, but I don't have experiency or enough knowledge to choose one of them (I don't know the brands, if they are reliable, etc).

I found RTL2838U/R820T2. Is it good? What are the other boards that you know? Sorry about the questions, but I'm kind of new here.
