On what receiver are you trying that? Using what version of OpenPLi and what files?

I see with this dongle even more is possible... e.g. FM radio also... All the features it offers is not suitable for E2... but A plugin could be made...

But still it would be a 'nice' object to integrate something of it in E2 by 'extend' the DVB-T service reference 'options' At least it would be 'helpful' to let the thing 'tune' via a service reference in common settings.

Of course that would be great.
For now the plugin works fine, the condition is a good signal/antenna.
 
@athoik significantly improved the detection of the existing channels in the list
in his latest update.

ET10000 , SDGR OP5 develop. updated.

I haven't installed anything. I use the SDGR radio plugin which comes with the image.

I remember to have got it working hearing FM services months ago.

 

Tuner is already blacklisted on /etc/modprobe.d/ 

blacklist dvb_usb_rtl28xxu

It's not a DVB service, so extending the DVB-T doesn't seem the right approach.

Although having a gstreamer plugin might be a better idea, and there is already one here: https://github.com/P.../fmradioservice


Unfortunately it doesn't produce good sound here, so I never spend more time on this..

Using the same "idea" like "fmradioservice", and the help of DAB/DAB+ library, we can easily integrate it on E2 using 4097 service ;)

Try reinstalling rtl-sdr.

btw, the librtlsdr.so.0 should be a simlink to librtlsdr.so.0.5git

root@osnino:~# ls -la /usr/lib/librtlsdr.so.0
lrwxrwxrwx    1 root     root            19 Oct 21  2017 /usr/lib/librtlsdr.so.0 -> librtlsdr.so.0.5git

09b1ab94e3d8217424dc9afbff6fb9a8  /usr/lib/librtlsdr.so.0

 

Reinstalled,

Now FM works, but DAB it gives the same error than before, but now with libfftw3f.so.3

In lib folder that libfftw3f.so.3 is a simlink to libfftw3f.so.3.4.4

Are you sure you didn't install something from external sources?

You can reinstall it.

opkg install libfftwf --force-reinstall

Try with this parameter enabled:

        -Q          if set, set autogain for device true

Can you provide your findings here: https://github.com/J...-cmdline/issues

Maybe the dab-cmdline author can understand why signal is not stable, like in welle.io.

I think the problem might related with the PPM frequency (frequency offset).

The program supports it using -p parameter (eg -p 51).

You can read more here:

http://davidnelson.me/?p=371

http://314256.blogsp...orkout-ppm.html

Thee rtl_test is available, the Kal, not yet, but will build the following days.

So give a try with ppm suggested by rtl_test.

Your sgnal shows great variations.
I do not know why, noise from the receiver and the like ???
I use an extensible USB cable with ferrite rings.
The aerial is a piece of wire hangs out of the window.
 
It is true that sensitivity or something else is not the same as with Windows or android
but with a small antenna out there and with the above USB cable I have a great ,reception and audio
And there are no such big variations of signal .
 
I have SNR 4 or 5 and quality is 100, sometimes less ( 94 -100}

I've already tried Direct USB to receiver, and using a high quality cable, both give same results.

I have an outside Vertical Band III aerial for DAB.
