Arrrgh! Apologies to all. I totally missed the all-important "2"
at the end of Irene's gr_make_io_signature2 call. Please ignore my

Hi List,
Just re-stating the issues I am having with capturing IF samples of an RF
signal: I am trying to sample a 16MHz wide spectral content from a signal,
originally centered at 2.414 GHz. I am using RFX2400, gnuradio 3.1.2 and using
following command:
python usrp_rx_cfile.py -f 2404.5M -s

Yeah, that's a bit confusing and a good
I am currently trying to get some basic code working to test that my
shiny new USRP is working correctly. I have been going over the
code/examples/list archives for a few weeks on and off, but most of
the code examples are for the basic RX/TX boards, and I only have two
RFX2400's.
My testing plan

Irene,
I believe the problem is that you are trying to have two different
types of output streams. According to the documentation on
gr_io_signature, it looks like multiple output streams must
all be of the same type. Or at least of types that have the
same size.
In your code, you try to decla
Hi again,
Can I assume the following? : because I am using the USRP, if when adding
the printf I do not get any under-run everthing is OK (i.e. the behaviour is
the same with and without the printf's) ?
Thanks!

Hi,
i've done the simulation, but i've a question. In the graphs the program did,
the are, in the constellation rappresentation, blue and red points. What do
they rappresent?
