Software defined radio with (ABANDONED)

#1 Post by Mercedes350se »

Found this site as a result of a post on another forum:

http://superkuh.com/gnuradio.html

Anybody doing this with Puppy and on which version?

Thanks for the tip. Maybe place a duplicate in 'Hardware' section since it benefits from some fiddling, maybe also in 'Development' as scope for coding mods. too?
Folks thinking this may be a little way out, might prefer the easy-cheating option:
http://www.ebay.co.uk/itm/Digital-TV-Bo ... 6rk%3D7%26
although it doesn't work on NTSC (US, Canada &Mexico).

It's deals like this that make the PRC great and the HK division, greatest! They used to invent and build stuff in this sector in the UK when I were 't lad. Back then, our rockets were bigger, better and more reliable than von Braun's in the USA. What went wrong?!

Driver

#3 Post by DC »

Awaiting the driver
rtl2832u driver, kernel 3.6. 3.5 RC kernel.
from this post about 3/4 down the page

http://www.murga-linux.com/puppy/viewto ... &start=570

However I do have the driver working in the puppy 528 series for DVB so that might be a starting point for you.

Ta! My rtl2832u is winging its way from HK as we speak.

I was really looking for advice on things like rtlsdr, GNURadio and/or Gqrx.

Edit: I have booted into my frugal install of Macpup 5.2.8 and have found this site:

http://gnuradio.org/redmine/projects/gn ... stallingGR

which states "For the impatient: open a terminal window, move to the directory you would like the source files to be stored (e.g. 'cd src/') and run this command:

$ wget http://www.sbrac.org/files/build-gnuradio && chmod a+x ./build-gnuradio && ./build-gnuradio

build-gnuradio is downloaded but I get this message:

Please run this script as an ordinary user
it will acquire root privileges as it needs them via "sudo".

I was under the impression that I was "an ordinary user".

Open the script and remove every sudo command from it. Generic advice for those sudo included scripts.

BK wrote yesterday on his blog:
I have configured the 3.2.28 kernel the same, except enabled some more digital radio/tv drivers, plus enabled KMS by-default for Radeon and Intel i915 video.
So maybe we will be get lucky?

I thought I went through the script methodically but without joy. Operator error I would think!

Moving away from the build script altogether another thought was to use SDR# as described here:

http://rtlsdr.org/softwarelinux

I am up to my ears with domestic chores at the moment so haven't the time necessary to try the method.

I am looking forward to hearing of your success.

rtl-sdr

#9 Post by superkuh »

Hi. I'm the superkuh who runs the site referenced in this thread. I just thought I'd pop in to clear up some things.

You don't need to install GNU Radio in order to use rtl-sdr. If you want to use GNU Radio based receivers like gqrx, sure, but there are plenty of receivers which just use the raw output of rtl-sdr. The build-gnuradio script does do handy things like setting up udev rules for the dongle though... which may or may not apply to Puppy.

In order to build rtl-sdr binaries you only need to follow the instructions on the Osmocom rtl-sdr wiki, http://sdr.osmocom.org/trac/wiki/rtl-sdr

Code: Select all

git clone git://git.osmocom.org/rtl-sdr.git
cd rtl-sdr/
mkdir build
cd build
cmake ../
make
sudo make install
sudo ldconfig
Then you can play with rtl_fm to do some quick decoding, or use a third party SDR application like the above referenced SDR#. Now that you have rtl-sdr installed head on over to http://sdr.osmocom.org/trac/wiki/rtl-sdr#KnownApps and pick up software to process the data.

If you run into any problems with the rtl-sdr compile stop in to Freenode IRC's ##rtlsdr. It's very active.

Thank you but I tried all that with Zorin OS 6 - based on Ubuntu 12.04 I think - so that I "shouldn't" have any problems.

All fine in theory! Gave up in the end. Life is too short.

Noob question. How to "stop in to Freenode IRC's ##rtlsdr. It's very active."?

Since this is an increasing vs decreasing area of need it seems this thread needs to be re-opened.

I have tried to follow the instructions to install build-gnuradio and hit a wall.

I am using Exprimo 5x15 at the moment.

1. It wants to run with a non-root user.
(I commented-out that section of the build code & moved on)

2. Then it complained that there was insufficient space - even though there's 11G available.
(I have been trying to work-out a solution elsewhere but it seems the thread belongs here.)

In this other discussion someone blamed Puppy for being the problem - I am thinking that someone who is familiar with Puppy will spot the problem and the solution.
