Hi Pedro,

Buy a RTL dongle, since they're almost free. If it doesn't do what you 
want, then you'll know more about what you want.

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.

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.

Marcus,

Below $120 is okay for me. Actually, the features are not important

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

Thanks for any help.

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.

Marcus,
So everyone is thinking it:  Show a little discuss-gnuradio love and set up an 
educational one time group buy.  I have had SDR envy for some time; stuck with 
RTL/Hermes/Funcube, when what I really need is some new Ettus hardware.  It 
NEVER shows up on Ebay it seems.
Think how many less "I can't get gnuradio to work with ;  can't you guys do this for me on this discussion list" responses you 
would have to create.
