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?!

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

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.

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.

Help, please?
