Hello every buddy
can one guide me how we can use the code of
*raw2num_f.c* in gnuradio-companion.that code available on line ...just
type the word.
.guide me if you know i need it in my work

Mahesh,
I am not sure if it can be used as a block in gnuradio-companion.
This is how I understand it.
What this code does is to read from a binary file containing float
numbers(for example the data that gets dumped by a file sink with float
input type) and stores it in a text file so that you ca

Piotr,
One problem is that if you cannot keep up, adding in all-zeros data will
just make it harder to keep up. In general, modern PCs should be able to
keep up with 25 MS/s without problem unless you are doing a lot of
processing. We are actually able to keep up with 300 MS/s on the X300. So

I ‘m trying to generate the LTE_flowgraph_top_level.grc but the Decode PBCH

Hi Martin and all,
I am looking at some AF stuff for now, where the delay is much better.
I am using something similar to HPD at the relay to implement some gain to the
payload samples only. I call

Hi Virgilios,
This sounds like an interface mismatch between blocks. To answer your
question accurately it would be very helpful to know which version of
GNU Radio and which gr-lte version you use. Branch and day of last
commit should be sufficient. A
Hi Jim,
You've made a great help, thank you. GnuRadio together with GRC runs now on
my RPi, modules Sinks and Sources appeared on GRC module menu and I could
build Gqrx as well, it also works. As a side issue I think RPi's onboard
audio circuitry and/or audio drivers cause some incompatibility
That's true. You can fix some of the issues by using preemptible kernels
and setting RTPRIO, but there can still be glitches. Certainly a block
which reads the streams tags and inserts zeros would not be too hard.

Clayton's sdr-examples are for GnuRadio 3.7.1. Your
issue is that you haven't built gr-iqbal. It's not really
needed, so you can just delete that block in the

I've tried pager_rx.py on bladeRF, and it works fine
here (GnuRadio 3.7.2.1 and Ubuntu 13.04). Tons of

I've made some changes to the code to work better
with bladeRF (mostly with the gain setting).
