Hello list,
The UHD work in the next branch has been merged into the master. These
changes include new FPGA and firmware images, changes uhd host code, and
changes to gnuradio gr-uhd.

I'm very intersted in this project and will help to make things happen. I
can help in any part of the design, but I have more experience in FPGA

Hi all,
Making some tests I have found that my system (USRP + RFX900) transmits an
important signal (it seems a tone) without any application running, just when I
plug the power source it transmits this unwanted signal. I'm working at the

Dear list,
i somehow can't get the UHD working with GRC. Detecting an USRP2 with
uhd_find_devices works just fine.
I am building from git (master) (what should include the UHD since today.
I'm also seeing the gr-uhd directory.)
I think that the issue is with ./configure, because there i can't

I don't know if this is kosher, but has anyone looked at the (vast array of)
offerings from Comblocks (comblock.com)? They sell FPGA IP cores for all of
their hardware, and it seems like it might be a good match for building a
basic I/Q acquisition system. Here's a full product list:
First of all, thank you for your advice.
Now i encountered another Problem:

everything works fine (well, not everything, but at least the installation

Hi all,
Am disappointed with the way GNURadio is getting into.
I see all the discussion around is to promote the products of Ettus
Research.
Agreed!. Great work from Ettus Research.
But there are many boards available which are far better in capability vs
price. I don't want to mention them

If you created a custom block in python that would do the right thing as
far as writing the file and handling the data; then you could use the

We definitely did not design with space applications in mind.

I am using the traditional driver. Maybe I can try to use another computer
or to put the board in the other slot,
and see if the problem remains the same.

Thanks a lot for your help. Could you explain how to slow down the FPGA/ADC

This is a host code modification.

This is very old topic. I have read a DSP book. But I find that I still not

Why in channelizer use low pass filter, in my imagine channelizer will use

Marcus, Thanks for reply.
That is make sense, so the point become how to convert the signal to
baseband.

Hi Marcus,
In your design there is only a single RX. I think it is better to build an
expandable board which can expand 2 RX 3 RX...
That will only introduce a little more cost but will meet much more people's

Oh, that's relatively easy--you multiply it with a complex signal at the
same frequency--that's
exactly how it's done in hardware, and it works
