D'oh! Thanks that did the trick. For everyone who is interested, this is
the snippet of working code:
gr_complex *out = (gr_complex *) output_items[0];
int noi = noutput_items;
gr_complex temp1[noi];
gr_complex temp2[noi];
// do something with temp1 and temp2
volk_32f_x2_add_32f_a((float *)out,
Sreeraj,
Removing that code appears to have fixed the startup problem. When I
execute gr_filter_design, the following message is displayed on the
console prior to the display of the gr_filter_design GUI:
QInotifyFileSystemWatcherEngine::addPaths: inotify_add_watch failed: No
such file or direct
Just add the complex stream as floats and multiply the length of the
operation x2.

Hi all,
Just a little question about the behavior of the DUC cordic:
The DUC cordic resets phase when a new transmit burst begins (e.g. after a
long underflow). Does this also happens when a packet with a new SOB-tag
(and associated time-tag) arrives at the USRP?
Thanks a lot,
Fran

Hi list,
I am currently trying to wrap my head around volk and have some
questions concerning orc.
- Is writing an *.orc file and adding it to the appropriate header under
volk/include/volk/ everything that has to be done to get an initial volk
kernel?
- If I am using orc, do I still have to
Greetings,
I would like to ask you how to read the data stored in a vector sink. I tried
the solutions I found in the discussion list. You can see some part of my

Swig stuff are python bindings to C or C++ code. So in your example
pfb_clock_sync_ccf() has been coded in C++, and
_digital_swig.pfb_clock_sync_ccf() is the generated python wrapper to
access the C++ pfb_clock_sync_ccf() from a python script.

Got it. How to figure out the frequency USRP1 uses to digitize the signal?
Is 64M samples/sec the default configuration? Thanks.

The decimation rate determines the final sample rate.

I use USRP1 and RFX 900 daughter board to receive an 925MHz signal. The

base band signal automatically. Can you tell me what is the frequency to
