A new SDR on Kickstarter

Hi Guys,
Just saw this project on Kickstarter.
http://www.kickstarter.com/projects/mossmann/hackrf-an-open-source-sdr-platform

It is an interesting low cost SDR with 20MHz bandwidth.

It seems like SDR is becoming more popular every day and the number of
low
cost SDR devices are on the rise.

I am thinking about backing it up, but I am not sure of 20MHz is enough
for
the applications I have in mind.

What do you think?

BR,
Farhad

Thanks, Farhad. I designed HackRF for 20 MHz with 8 bit quadrature
samples because it is at the maximum rate that can be transferred over
USB 2.0 (Hi-Speed). It’s enough bandwidth for most SDR applications
I’ve seen. What applications do you have in mind?

will it work with GRC?

It already does.

The hackrf is supported through the gr-osmosdr gnuradio hardware
abstraction block, both RX & TX.

Hi Michael,
You did a great job, my application is pure signal processing and signal
analysis. I don’t know if I could go for 8bits and 20MHz,

I am seriously thinking about making a small adapter board for the MyriadRF and
connect it to my Zedboard (http://myriadrf.org/)
It is going to be more expensive, but it is more suitable for my need.

Such an adapter board is in development and if you check the Myriad-RF
website around September there should be an announcement.

But, I may change my mind and purchase one just for comparison.

I think both have their own particular strengths and I imagine you’d
be far from the only person with one (or more) of each.

Cheers,

Andrew

Hi Andrew,
It will be cool to get one of those boards, I see a lot of potential
with
the combination of Zedboard and Myriad RF, it can be a comple SDR
platform.

I would like to know more about the board and when it will be available,

Cheers,

I’ll see if there is any preliminary info we can share and if so I’ll
e-mail you off-list (and will post details here in due course once
there is some sort of announcement to make).

Cheers,

Andrew

PS. Congratulations to Michael! I was watching the Kickstarter
campaign with delight following the announcement yesterday :o)

I love the 6 GHz capability, but I really miss full duplex, this locks
out
stuff like OpenBTS or the open source LTE system everyone is hoping for
:slight_smile:
For the moment I will go with the BladeRF, also a small design, nice for
travel. Still I am tempted to order a hackrf :slight_smile:

Do not expect more than a few mW, but MMICs are cheaply available, no
problem to boost it a bit :slight_smile:

I’m wondering what the power output is on this? I haven’t seen it
anywhere.
I wouldn’t imagine it’s very much. 100mw?

The maximum output power varies by frequency. See:

When can you ship to Australia?
We are interested in purchasing for university SATCOM project.
