Hi All:
I am sorry to bother the list with such newbie questions, but I am climbing the
gnuradio and C++ learning curve. Hope you don’t mind!
I am working on a new OOT block that is similar to the Repeat block, but allows
for a variable interpolation rate. I followed the Guided Tutorials (tha
Does a stream-to-vector block buffer the input stream? For example,
if I want to create a length 2048-sample vector from a stream, is the
vector updated every 2048 samples? Or is it updated every sample?

make sure that I'm n

Ok, thanks, One more question... So does that mean we control the NCO from the
software?
I will have a look at those blocks.
thanks,

Hi,
Thanks for the reply. I guess I am just trying to better understand this
diagram:

I understand what the decimating filters are doing, but I'm a little unclear
about the NCO. Does this compon

Hi,
Sorry if this is a simple question. I'm trying to figure out what
synchronization is done by the FPGA on the USRP2. Does it perform both
phase and freq synch? If I want to implement a simple digital modulation
tx-rx, do I just need to do timing synchronization? Is there a simple
example

Hello,
I am am new to the gnuradio system and I have a USRP1 board running

Hi all,
I was just wondering why are there 2 antenna inputs on the BasicRX and
the LFRX dbs? As well as their counterparts on the corresponding tx dbs?
Thanks,

configured/compiled to use USRP. Before this I configured/compiled 3.0.4
without USRP (using ./configure, make and make install). ./configure

The error reporting is unfortunately not as specific as it could be.
In my experience, the most frequent cause of the above is
Greetings.
Got gnuradio compiled, made, and actually ran the dialtone test last night.
However, when I attempted the same this morning, I got the following message
(which, I have to say, I've gotten before but thought last night's test had
eliminated).
Any thoughts?
