Hi
I agree that the Odroids are pretty good.  Marcus Leech pointed them out
to me.  I’ve got a couple XU4s (8 cores) that work pretty well.  What I really
like is that with the mate operating system and EMMC’s they boot in just
a few seconds.

I use an Odroid C2 64bit running Debian/Jessie with 2 Gbytes of RAM with
an optional real time clock and 32 GByte EMMC hard drive.

There's also an optional USB sound card but I use the HDMI sound instead.

I'm using GNURadio 3.7.12.0 with a HackRF at low bandwidths - 2-5 MHz.

Other than the keyboard/mouse, a HackRF is the only other device
connected to the USB.

I got rid of my pi3 - to slow. It uses a microSD card for the hard drive
and memory - which may have been the cause of the random hangs when
using it interactively. Not long hangs but long enough and frequent
enough for it to become extremely annoying to me.

it is easier to write a modem for a desktop CPU, but a good C++

even makes this win more or less free (no need to write your own

you'll find that's generally a mistake. I'd suggest getting 
comfortable with GR and SDR on the desktop before moving on to 
embedded systems, because there's a lot to learn in both and it's 
going to be worse if you have to learn them both at the same time.

Another thing I find is that there's a big gap in comprehension about 
how much 'stuff' happens to each and every sample for even relatively simple

  (from a 10kft view) DSP flows.

"My CPU runs at 2.5GHz, and I'm only bringing in a measly 10MHz, why is 
this not working for me?"


"Why can't I make a precipitously-steep filter--this is software, after 
all.  It's all kinda virtual, right?"


Folks who are coming at this from the "apps" world may never have 
considered or experienced or pondered exactly what happens inside
  the "sausage factory" we call a modern operating system. 
"Sample-arrives>[MAGIC]->it's in my app>[MORE 
MAGIC]>cool stuff happens".


If you're coming from a world where real-world "events" happen at the 
rate of user-clicks, thinking about being responsive to "events" that may be
  happening millions of times per second may be a bit of a cognitive 
shock...


Just random thoughts from years and years watching this ballet play out

[Discuss-gnuradio] Hello GNURadio from the Amateur Radio World

[Will Gilliam]

Hello Peoples, I just signed up for the discuss list, so I thought I would
introduce myself

My name is Will Gilliam and I am a FCC licensed General amateur radio
operator. (Ki7OXA)

My first draw into GNURadio was the possibility of operating a high
frequency 5W radio
built from a Raspberry Pi 3, an Soundcard SDR radio. I love the idea of
embedded computing, SDR radios and GNURadio. Its small, its portable, and
because it involves a computer, the radio can be anything, even a modem.
Add amateur radio license, even the Element 2 technicians, your still
having fun VHF and up...

Doing anything on a large computer is easy. Got more work? throw more cpu
time on the task, but anyone that tinkers within the Embedded world, you
know you really can't do that to a large degree.

My experience with GNURadio is so far self taught and not pleasant. I am
uncertain if my poor experiences are from lack of experience, not enough
computer power, or a mix of both.

Is there anyone that is using raspberry pi's and GNURadio on any sort of
realtime projects? Is there a better board to use or one that GNURadio is
going to try to support?


Look forward to learning and chatting with you all

Re: [Discuss-gnuradio] Hello and help to get the tutorials

[Estrada Lupianez, Jenniffer Marie]

Adrian,

If Boost is installed on the machine, and you are still getting that error, 
then the next thing to check is your environment variables. You may need to set 
BOOST_LIBRARYDIR to the directory containing Boost libraries or BOOST_ROOT to 
the location of Boost. BOOSTROOT (or BOOST_ROOT) must point to the location 
where Boost is.

Check these environment variables on your system:
BOOST_ROOT - Preferred installation prefix  (or BOOSTROOT)
BOOST_INCLUDEDIR   - Preferred include directory e.g. /include
BOOST_LIBRARYDIR   - Preferred library directory e.g. /lib

Seems like either Boost version should work.

From within the CMakeList.txt file in the top directory of the git repo:


# Find boost

if(UNIX AND EXISTS "/usr/lib64")
list(APPEND BOOST_LIBRARYDIR "/usr/lib64") #fedora 64-bit fix

Re: [Discuss-gnuradio] Hello all,

[Marcus Müller]

Hi Jahnavendra!

Welcome to the GNU Radio mailing list.

So, your question is asked so often, we have a FAQ entry for that:

https://wiki.gnuradio.org/index.php/FAQ#What_is_the_file_format_of_a_file_sink.3F_How_can_I_read_files_produced_by_a_file_sink.3F

Best regards,

Marcus

PS: really, nothing wrong here, but just a hint for the future: Use a
/descriptive/ subject rather than a salutation in the Subject line of
emails; for example "File Sink file format" would've told me directly
away what you're looking for, and I'd recognize the email in a few weeks
again when looking for it; "Hello all" tells me nothing.

[Discuss-gnuradio] Hello all,

[Jahnavendra Mattipa]

I am currently working with the USRP using GNU Radio. I want to record the
data for analysis purpose so i am searched for recorded option in GNURadio
companion and i got a block called "File Sink". After execution of the file
it record some data in the order of MB's, when i am trying to open that
file it is in unknown format to open. If anybody faced this type of issue
or if anybody knows about this give me some advices to open that recorded
file.
  Thanking you all.

[Discuss-gnuradio] Hello, 2017!

[Ben Hilburn]

Hi all -

Happy New Year! Last year was a great year for the GNU Radio project, and I
think 2017 is going to be even better. We got a lot of key infrastructure
work done in 2016 (and I'm not talking about just code), and as a result we
are very well situated to knock out our goals over the next year.

Johnathan and I will be sharing more details over the next couple of weeks
about both on-going and new efforts, as well as sharing some general
updates about a lot of the behind-the-scenes stuff that we finished up late
last year. I do have a few items to share now, though:

*FOSDEM & DARPA Hackfest Reminder*
The schedule has been set for the SDR Dev Room at FOSDEM `17, and it's a
great lineup. If you can make it, let us know that you'll be there so we
know to look for you! I also want to acknowledge the organizers of the dev
room, whom are well-known GNU Radio developers: Martin Braun, Philip
Balister, and Sylvain Munaut.

   - FOSDEM 2017: https://fosdem.org/2017/
   - SDR Dev Room:
   https://fosdem.org/2017/schedule/track/software_defined_radio/

Also, don't forget that Tom Rondeau (former lead of the GNU Radio project,
now a DARPA PM), is running a DARPA-sponsored hackfest for the three days
leading up to FOSDEM. I'm really excited to see how GNU Radio is used by
the participants, and hope to see you there!

   - DARPA Hackfest:

http://www.cvent.com/events/darpa-mto-hackfest-brussels/event-summary-c64f4cd412334d6a93fca4f202378188.aspx
   


*Call for Blog Posts*
We closed out 2016 with some great posts on the GNU Radio blog, and I would
like to keep the trend going. The GNU Radio website gets between 800-1000
unique hits on most weekdays, so it's a great venue for sharing your work
and ideas. If you're interested in writing up something, please let me know!

   - GNU Radio blog: http://gnuradio.org/blog/

*Reminder for January Call*
The GNU Radio Project call is on January 19th! Mark your calendars.

   - http://gnuradio.org/events/

*Get Involved!*
One of the topics that came up a couple of times at GRCon16 was that it can
be hard to know where to start if you want to contribute back to the
project. While there is some documentation about this on the Redmine site,
we are working on putting together new, more comprehensive, content. Until
that's ready, if you want to get involved and aren't sure how, just let me
know! We welcome anyone who wants to contribute, and you don't need to be
an expert to make a big impact.

It's a great time for the project, I'm really looking forward to the coming
year. As usual, please reach out to me if you have any questions,
suggestions, or good jokes, and keep an eye out for more updates soon!

Cheers,
Ben

Monika,
please reply to the list!

You should do either
a) follow the long instructions on that page, OR
b) use the build-gnuradio script to get GNU Radio (see the first
sentence of that page), OR
c) use pybombs (not mentioned on that page, because that page is a bit
outdated).

Probably b) or c) are the best option for you, because they will
automatically make sure that all the libraries you need are installed.
So, can you go to your build/ directory and do
sudo make uninstall

After that, you just take the c) route [1]

git clone -r https://github.com/pybombs/pybombs.git  cd pybombs  
./app_store.py


Best regards,
Marcus

[Discuss-gnuradio] hello world ex. grc problem

[mehmet kabasakal]

Hi everyone,

I am newbie both at gnuradio and linux environment and I am currently
working on a project about usrp.
First of all I've installed the gnuradio-3.2.2 and ubuntu 9.04. Then i tried
to run the dial tone example.

When i run dial tone example on
http://www.gnu.org/software/gnuradio/doc/exploring-gnuradio.html on the
terminal
there is nothing wrong, i mean it doesn't give any error messages but i
can't hear anything from my computer's
speakers. Do i have to do any extra process to execute the code?

My second question is about the grc. I wanted to use this gui to try some
examples. But when i write the terminal
grc i got this messages;

meh...@mehmet-laptop:~$ grc
Generic Colouriser 1.1

grc [options] command [args]

Options:
-e --stderrredirect stderr. If this option is selected,
   do not automatically redirect stdout
-s --stdoutredirect stdout, even if -e is selected
-c name --config=nameuse name as configuration file for grcat
--colour=word  word is one of: on, off, auto

Is there something wrong with it? How can i open the grc GUI ?

Thanks ...

I think you misunderstood my last email, if you want to know where
your program is exiting from, you need to put in statements where
things exit, for example
if self.u.tune(self.subdev.which(), self.subdev, options.freq):
print Tuned to, options.freq/1e6, MHz
else:
print Unable to tune daughter card, exiting
  sys.exit(1)

Then you will know /why/ your script is failing, and you can go about fixing it.

Of course, if by Fmstereo you mean broadcast FM radio, you're not going to
be able to listen with the RFX2400. You need something like TVRX.

 what could  be the result of this? and how can l correct this.

First, please see http://gnuradio.org/trac/wiki/ReportingErrors
regarding how to format your questions.

Second, you indentation is still all messed up; it may be an artifact
from your c/p, but python depends very heavily on the spacing (spaces
and tabs, for example, are treated differently).  Please re-read the
original link I sent you.

Finally, I would guess that the program is doing exactly what you tell it to:

if self.u.tune(self.subdev.which(), self.subdev, options.freq):
 print Tuned to, options.freq/1e6, MHz
else:
 sys.exit(1)

Because you didn't give an output for the error message, it just
closes silently and you are left confused.  Try putting a print in
there to see if that's where you're failing.

Python parses your code based on the indentation so it doesn't have to
use brackets to separate logical portions of code.  You did that
incorrectly somehow.

Hello Tom ! 
 
Thank you for your reply. I have the 2nd edition ( Low Price Edition ).
 
Here is my question rephrased. 
 
The sifting property for the cts dirac delta fn has an INTEGRAL.
The sifting property for the discrete delta fn has an infinite sum in it.
 
So we cannot 1st say as is said in the book that delta is the Dirac delta 
function and the coolly proceed and apply the sifting property of the discrete
delta function as has been done below.

Do you see my question ?

Nope, sorry, I still don't see the problem. I'm cool with how they 
present this in the book. It sounds like your problem is based on the 
definition of the Dirac function, and that might be true, but I've never 
much concerned myself with specifics like that. The outcome of their 
math in the sampling process still works.

 typo ? Shouled this have been the discrete delta function? If it is'nt, how 
 do the
 above steps hold?

Well, if you have the first printing, you can check here first:

But otherwise, my comment would be... a typo in an Oppenheim  Schafer book?  9 
years
after being published and after countless peer reviews?  And you found it?  One 
thing
for sure is you're not lacking audacity and enthusiasm.  Keep going.

[Discuss-gnuradio] hello, the Dataflow library, a GUI dataflow editor, and Google Summer of Code

[Stjepan Rajko]

Hello GNU Radio community,

I've been following this list for some time now after being referred
to it by Phil Endecott on the boost list.  He had seen a talk on GNU
Radio, and suggested I look into it in regards to a dataflow library I
am developing.  Even though I don't know much about software defined
radio, the work you are doing here seems really fascinating!

I am particularly interested in your project because of the my work
with the Dataflow library:
http://dancinghacker.com/code/dataflow/

That library is evolving towards a generic dataflow library, with the
goal that any dataflow-oriented framework (like GNU Radio) should be
easy to adapt for use with the dataflow library and anything built on
top of it.  For example, I've put together a very basic GUI dataflow
editor:
http://dancinghacker.com/code/dataflow/dataflow/introduction/examples/fltk_gui.html
If I added a support layer that would integrate GNU Radio with the
Dataflow library, the GUI editor could easily work with GNU Radio
components (rather than with components based on Boost.Signals with
which it is currently using).

For a while I've been very interested in adding support for GNU Radio
in the Dataflow library, as well as implementing a serious GUI
dataflow editor that would also support running the programs and
visualizing / inputing data and control values, but currently I am
focused on finishing the Boost.Signals-related functionality so I can
submit it for review with Boost.  This summer I should have more time,
and (bonus) Google Summer of Code 2008 has just been announced:

http://code.google.com/soc/2008/

Will GNU Radio be participating in GSoC, and would there be any
interest in having the following done as a GSoC project:
a) GNU Radio support added to the Dataflow library
b) developing a good generic GUI environment for the Dataflow library
which could then be used to design and run GNU Radio apps.

Please let me know, as I'd love to get involved (especially as a part
of GSoC since then I can devote some serious time to it).

Thanks and regards,

Stjepan

[Discuss-gnuradio] Hello all (asking for some help)

[eenrti]

I know it will sound strange since for the last day that I have been 
subscribed to this list I can see many advanced (at least to me) topics 
but I am new to it, I have just purchased the USRP motherboard and I 
have many many questions. To start with the more simple ones, I would 
like to ask what are the steps I have to take to install the software.
I am planning to use the USRP card as a data acquisition system, 
sampling I, Q channels and passing them through the USB and record them 
on a hard disk.
What software do I need to install and where to start from? My 
understanding until now is that I better go with Linux since Windows 
platform seems to have some incomplete patches yet.
I suppose that first I have to check the dependencies of my operating 
system that are required.
Then I have to download the gnuradio folder (from the stable release) 
which includes the core programs in the folder trunk and install this 
with all of its components.


Would that be all? Do I need to download a firmware for the FPGA as well 
or does it come with preinstalled firmware?


I hope you can guide me around

thank you all

Rigas

[Discuss-gnuradio] Hello everyone : )

[Alex Miua]

Hello people : ) 

This is Alex once again. I read a little bit of Python and Linux fundamentals 
over the past days and now I feel I am in a better position to deal with making 
a software radio spectrum analyzer.

Could anyone tell me what all boards of the USRP will I require to build that ? 
Also can I use a cheaper subsitute for it ? 

And oh , guys, is anyone willing to sell an old one to me ? 

This IS fun. I hope it works out well.

Thank you,
Alex : )

 Hi mailing list.
 
 I'm really interested in learning more about software radio. I think
 this is revolutionary technology... with the potential of changing the
 face of media and free information and general stuff that may facilitate
 democracy. Anyway... I'm signing up for classes so I can learn more
 about radio engineering and computer science. Looking forward to
 learning much.

[Discuss-gnuradio] Hello world Software radios

[omar nasr]

Dear all,
I am Omar Nasr, I am a TA/RA, EE department, Cairo 
university. I want to work in the developement of software radios in my PhD 
degree. I hope I have the ability to learn how to USE the gnuradio and then I 
hope to contibute in the developement process. the docmentation for the gnuradio 
are not sufficient to start, I have learned Paython and I tried to use it to run 
the gnuiradio (I am using Windows XP), but till now I got nothing. If anyone 
have better docmentation than that exists on the websire or can guide me towards 
my hello world example; this will be great.

waiting for your kind reply
