So to tune two USRP N210s connected by a MIMO cable, I should set the
command time to be some time spec, and then re-tune both channels to the
same frequency, thus giving them the same phase offset?
i.e. My code is looking more like:
self.cmd_time = self.uhd_usrp_source_0.uhd.time_spec_t(.1)
self.

Everything you see in these headers should be available in python:

There's already a "get_time_now" method swigged in the
gr_uhd_usrp_{source,sink} block, along with a "get_time_last_pps" method if you
need to synchronize to an absolute time.

Dear All,
I am new of SDR. I've read a lot and compiled Gnuradio and gr-baz on my macbook
snow leopard 10.6.8but nothing, gnuradio doesn't recognize my ezcap as
source...It's a week that I try different combinations but i really don't
understand what to change.
Can you help me?
Many Thanks

Hi Matt,
Could you pass us the apt repository address?
Will the included OpenBTS versio work with a single RFX900 and a USRP1?

Hi all,
I'm having some trouble using the C++ UHD API for writing Python code.
I understand that the code has been SWIG'd from C++ to Python.
Specifically, the C++ code I want to convert to Python is:

Hi Josh,
Definitely both daughterboards has different frequency ranges, I just wanted
to test the TX channel of the USRP2 to make sure is working.
That is the way I'm testing the LFTX, I have a spectrum analyzer connected
to the RX ports.
This is the flowgraph:

Hello all
I believe I have found a bug in digital_fll_band_edge_cc.cc: with the same
input under different cpu loads I see different outputs. It seems to have
something to do with how the block uses output history from the
output_items parameter. Modifying it to use its own internal buffer to

test_gr_filter fails here (I ran volk_profile before).

Hello,
I wonder if someone might be able to provide me with a link to an up
converter circuit? I want to extend the range (downwards) of my ezcap
dongle.
A Google search hasn't provided anything useful.
