Hello,
I'm interested in taking some binary data that I've generated using GNU
Radio and outputting it to hardware at TTL levels. The data would be coming
out at a relatively low frequency (50-100kHz). I haven't been able to find
anything describing the voltage levels possible using the BasicTX
I would like to add some type of carrier recovery to the GMSK demodulator in
GNU Radio, however I am having a bit of trouble getting something
implemented that works properly. I have tried using gr.costas_loop_cc to
add a costas loop for carrier recovery, but I am not quite sure how to
calculate
Hello all,
I am doing some work with the GMSK demodulator block that is provided as
part of GNU radio. I had been noticing some problems where sometimes the
demodulator would not be able to lock on to the signal (generated with an
agilent signal generator) properly and determined that the proble
I have a few questions related to the scalability of GNU Radio. Any insight
would be most appreciated.
1) I am unfamiliar with IPC, but understand how it could be useful to
increase computing power. What would be the first step in setting it up to
do distributed computing with GNU Radio?

Matt or anyone who knows,
I know that the BasicRX is listed as being able to receive signals from
2-300+ MHz. However, when I input signals from 0-2 MHz I am still able to
see them with the oscilloscope and fft plot. Could somebody let me know
exactly what components are on the board that affec
I have been digging through the code to try and understand the architecture
that GNU Radio works on. From flow_graph.py I have come to the
understanding that GNU radio creates and manages it's own memory buffering
scheme. This would seem to make it difficult to expand the platform to work
over m
In looking at the tools for designing FIR filters, I see that you can do it
by selecting cutoff frequencies and transition bandwidths. Is there a block
already in existence that allows you to design an FIR filter based on cutoff
frequency and maximum number of taps where the transition bandwidth
I have been reading about how the Tx path works in the USRP and was slightly
confused. I know that some of the interpolation is done in the FPGA and
some of it is done in the DUCs on the external chips. Noting the following
code from class usrp_standard_tx:

I know this is probably an extremely stupid question, but I wanted to get
some verification. I've noticed that the minimum decimation rate you can
use in all of the sample programs is 4 (giving you an effective sampling
rate of 16 MHz). If you are transmitting 1 real channel of data (16 bits)

Has anybody had any experience using the capture_to_file.py code from KD7LMO?
(http://kd7lmo.net/ground_gnuradio_software.html) I am interested in the
functionality to set up an IF frequency and bandwidth and dump the data to a
file. When I have attempted to run the program I have encountered t
I've determined that there are two possible solutions to my problem.
The first problem I do not have proper permissions on my user name in order
to access the USB? I've looked at a couple different methods for giving
myself permissions (I have access to root) and nothing seems to work.

Does anybody have a copy of the source code for the newest version of USRP
(not GR-USRP) or know of a place to get it besides Sourceforge CVS? The SF
CVS repository has been down the entire week and I am not hopeful that it
will be up anytime soon. Thanks for any help!

The repository is down...see link

Hopefully it will be fixed by tomorrow, I need to update as well.

I am experiencing the same error when making gr-usrp. Hopefully someone can
shed light. Someone offered up the suggestion that my usrp package was out
of date, but I have been unable to log into CVS to download the latest
version, it asks for a password even for anonymous log in and then times o
