Continued of above post. the RF tuner inside that stick is Elonics E4000.
It uses e4000.ko module...and it seems I have included it.

Software defined radio, SDR page:
http://sdr.osmocom.org/trac/wiki/rtl-sdr

Info about RTL2832U and RF tuner combo by Antti Palosaari:

RTL2832U SDR mode
One absolutely very interesting feature of that chip is so called SDR (Software-defined radio) mode. That undocumented mode is used to offer FM radio and DAB features, whilst DVB-T is demodulated traditionally by hardware. RTL2832U with a comibination of RF-tuner which supports very wide range frequencies (around 50-2000MHz) makes that device very interesting as a general poor man's SDR.

About Elonics RF tuner:

Elonics E4000 could be seen clearly center of that picture. 28.800MHz crystal is clock source for both E4000 and RTL2832U. There is four clearly visible wires, going through C11/C12/C13/C17, between tuner and demodulator. It is baseband (Zero-IF, 4 wires) I/Q signal interface which goes to the demodulator ADC.

E4000 is multi-mode direct conversion (aka Zero-IF) silicon RF-tuner. It supports wide range of different standards. Due to wide range of supported radio communication standards, it supports wide frequency range that makes it quite interesting RF tuner. Currently, I don't know any other DVB-T tuner which supports that large frequency range.

Making life more easy. I found Ubuntu launchpad repo for Gnuradio. It has a lot needed stuff. And hopefully the rest you can download from PPM. Probably this Gnuradio wants tens of dependencies, libs, libboost, etc, etc.
I tried to compile gnuradio, but getting everything right, it is mission impossible with this crappy laptop. When I test compile...everything else stops, cant browse, cant do anything. And when there is error, I have to start hunt the bug. Gnuradio and gr-osmosdr compile is not the easiest one, that has been tested. I happily rely to the ready made .debs

https://launchpad.net/~roman-moravcik/+ ... /+packages

After all the downloading, my 1 Gb savefile is now red, but:

SDR continues:

Quisk, not sure if it supports rtl2832U dongle. I couldnt get straight answer.

Anyway. I found Gnuradio with RTL2832U page with pics:

Thats it. I have placed starting points for all sdr hobbyists. I dont own this dongle, so I cant test it. But initial info can be found now.

Wow ... my head is spinning ...

Got home from painting at the church, grabbed some lunch, then checked email to find this flurry of activity.

I downloaded the two PET files and loaded them & tried:
"rtl_sdr -s 1443900"

No errors, just returned to the menu for rtl_sdr - not sure what it's supposed to do.

I don't know how I would test the device for TV as I don't see an app in the menu that does that.

Great to see that you got gnuRadio to run!

I have already downloaded and installed gnuradio via Puppy Package Manager but cannot get it to execute - is there something that I need to do after getting all of those files via PPM?

pemasu · #166 Post by **pemasu** » Sat 03 Aug 2013, 18:26

Edoc. VLC media player is good for TV watching. You need channels.conf file also, which has the channels info. I use w_scan commandline application for that. I think you can find several ways to create channels.conf file when you search the net for info.

http://208.109.22.214/puppy/viewtopic.p ... 66e#702081

Murga-forum has several posts how to use dvb tuner for watching, with vlc, smplayer, etc....

About Gnuradio. You can install gnuradio .deb from PPM, it craps most of the dependencies with it. There one page full of gnuradio plugins. Then install from that launchpad site the rest. osmo-sdr, gr-osmosdr, my compiled rtl-sdr or the same one from that site, uhd. I think you dont need to install again that compiled gnuradio from the site. I didnt. Gnuradio is python monster. You will need also python-gtk2 with the rest dependent python-cairo etc, also install python-nympy with dependencies. then copy from /usr/lib/libla* the libs to the /usr/lib and do the same to the /usr/lib/libblas*.

Then try in console: gnuradio-companion. And start to install the rest missing stuff. It might take couple of hours.

Gnuradio is absolute the most amazing, huge Python app, which needs a lot libs and dependencies to get the gui even starting. I admire those who have achieved to create it. But...I wanted to get the gui even once in my lifetime to start. Now I have done it. Lol.

edoc · #167 Post by **edoc** » Sat 03 Aug 2013, 18:29

Do I need to do the following?

Found at: http://radioware.nd.edu/documentation/i ... tion-guide

Two Python modules are necessary and very important in GNU Radio, Numeric and Numarray, which are used in Python for numerical computation purpose. They are available at: http://sourceforge.net/projects/numpy

Download the newest version of Numarray and Numpy. Extract the tarball then you can find the setup.py file. Use the following command to install

$ python setup.py install

At this point, I guess you should be able to install gnuradio-core without losing any packages. In the folder gnuradio-core downloaded from CVS, run the following commands

$ ./bootstrap
$ ./configure --enable-maintainer-mode
$ make
$ make check
$ make install

Now you have already got the key component of GNU Radio. Note that you may not be able to pass the `make check' if you didn't install Numeric and Numarray modules.

Read my post above. I mentioned python-nympy already and also that you have to manually fix the location of those 2 dependent folder of libs. It is known bug in all debian, ubuntu distros. Puppy does not see liblapack etc and libblas libs if they are not moved, copied or symlinked to the the /usr/lib.

So...first install python-nympy with PPM with dependencies. Then fix the libs location.

edoc · #169 Post by **edoc** » Sat 03 Aug 2013, 18:35

gnuradio-companion complains about pygtk missing.

I looked in Puppy Package Manager & it shows a bunch of files after a search but none of them are explicitly pygtk - do the results suggest that pygtk is in any of them?

pemasu · #170 Post by **pemasu** » Sat 03 Aug 2013, 18:38

Hmm Edoc. What if you read my posts first again. I am repeating myself.
Install python-gtk2 with all dependent other python-* .debs.

I am taking brake now....

edoc · #171 Post by **edoc** » Sat 03 Aug 2013, 19:06

Our posts passed each other ...

I just read what you wrote and will see what I can do ...

Then install from that launchpad site the rest. osmo-sdr, gr-osmosdr, my compiled rtl-sdr or the same one from that site, uhd. I think you dont need to install again that compiled gnuradio from the site. I didnt. Gnuradio is python monster. You will need also python-gtk2 with the rest dependent python-cairo etc, also install python-nympy with dependencies. then copy from /usr/lib/libla* the libs to the /usr/lib and do the same to the /usr/lib/libblas*.

python-nympy confused me until I realized there was a typo and it was python-numpy I was supposed to be getting!

This folder doesn't exist /usr/lib/libla*

I searched via PPM for libla and grabbed what was checked (libpack).

Then I searched for libla and found it in /usr/lib/lapack

pemasu · #172 Post by **pemasu** » Sat 03 Aug 2013, 19:21

Edoc. I think you should check first that the rtl-sdr sees your RF tuner.
In console: rtl_test -t

....and check if the tuner is found.

If not: modprobe -r dvb_usb_rtl28xxu
....which removes the dvb usb bridge driver and try again the above command.

About missing stuff. Just launch in while gnuradio-companion and add what is missing.

edoc · #173 Post by **edoc** » Sat 03 Aug 2013, 19:36

It finds the stick, but ...

"... kernel driver active or device claimed by second instance of librtlsdr."

"Detach or blacklist dvb_usb_rt128xxu or enable automatic detaching at compile time."

WDYT?

edoc · #174 Post by **edoc** » Sat 03 Aug 2013, 19:51

I tried blacklisting that module & rebooted.

That worked - it ran the benchmarking!

pemasu · #175 Post by **pemasu** » Sat 03 Aug 2013, 21:15

Yeah. Those dvb tuner - RF tuner combos dont have usb-modeswitch functionality. You can use only one of the features. Dvb-tuner or RF tuner property....it seems.

Okay....That is about all I now know about that RF tuner thing. I really dont quite follow what people do with these things.

edoc · #176 Post by **edoc** » Sat 03 Aug 2013, 21:24

w_scan -fc -c FI -M > /root/channels.conf

Doesn't work & can't find w_scan in PPM.

edoc · #177 Post by **edoc** » Sat 03 Aug 2013, 21:35

Dvbscan isn't in Raring?

Not found when I look in PPM.

I have for VLC channels info file created as vlc.xspf with w_scan

Dvbscan should be ok also.

pemasu · #178 Post by **pemasu** » Sat 03 Aug 2013, 21:41

Edoc. use google: w_scan deb

http://packages.debian.org/unstable/main/w-scan

And, your scanning cant work. You would scan finnish cable tv channels with those parameters.

w_scan --help
w_scan: invalid option -- '-'

usage: w_scan [options...]
-f type frontend type
What programs do you want to search for?
a = atsc (vsb/qam)
c = cable
s = sat
t = terrestrian [default]
-A N specify ATSC type
1 = Terrestrial [default]
2 = Cable
3 = both, Terrestrial and Cable
-c choose your country here:
DE, GB, US, AU, ..
? for list

-s choose your satellite here:
S19E2, S13E0, S15W0, ..
? for list
---output switches---
-G generate channels.conf for dvbsrc plugin
-k generate channels.dvb for kaffeine
-L generate VLC xspf playlist (experimental)
-M mplayer output instead of vdr channels.conf
-X tzap/czap/xine output instead of vdr channels.conf
-x generate initial tuning data for (dvb-)scan
-H view extended help (experts only)

I provide only the approximate information. You have to dig out what kind parameters USA broadcasts need. I cant know.

http://linuxtv.org/wiki/index.php/W_scan

Scanning ATSC VSB (United States, Over-the-Air)

Someting like: w_scan -fa -A1 -c US -L > /root/channels.conf

Use google, forum, someone from USA or from your state surely has posted the correct parameters.

And...You need to enable the dvb usb bridge driver and reboot. You cant use dvb-tuner before you enable it again.

pemasu · #179 Post by **pemasu** » Sat 03 Aug 2013, 21:55

Or....
The corrected terminal command for North American users:
Code:

w_scan -ft -c US -L > /root/vlc.xspf

dvbscan is in package dvb-tools ...or dvb-apps. Not quite sure.

My old post from year 2010 about my first test to use it:

http://murga-linux.com/puppy/viewtopic. ... 966#453966

edoc · #180 Post by **edoc** » Sat 03 Aug 2013, 22:12

I see the typo, it is w-scan rather than w_scan.

Downloaded & installed.

I tried "w_scan -ft -c US -L > /root/vlc.xspf"

ERROR: No Usable TERRCABLE_ATSC Card Found
Check wether dvd driver is loaded
and verify that no dvd application (i.e. vdr) is running.

BTW: PPM shows dvb-tools which looks like a handy package of tools but when it downloads & installs it contains only doc files - none of the tools.

Is there a proper way to report this so that it is fixed - or is that set of tools too old and has been discarded?
