Installation improvements

[ckuethe]

It would be nice if make install could install the sample applications in $TARGET/share/gnuradio/examples/ and if the detectMarkSpace hier block was also included in the AX.25 namespace

Hai, I am trying to add "gr-bruninga" module for GNURADIO 3.7.13.4 in Ubuntu 18.10, when i am running the flow-graph in GNURADIO, i am getting this below error. I am following the installation procedure givien by the author. Can anyone please tell what i am doing wrong and how can i solve this problem... Thanks in advance..

Traceback (most recent call last):
File "/home/resi/Documents/APRS.py", line 38, in

Did you set PYTHONPATH and LD_LIBRARY_PATH ?
Where is your gnuradio installation located ?

Dear Volker, Thanks a lot for your reply.... The below is my gnuradio path... /usr/bin/gnuradio-companion The below path is where afsk is installed /usr/local/lib/python2.7/dist-packages/afsk I cannot find PYTHONPATH and LD_LIBRARY_PATH variables when i run the "export" command...

First check

echo $PYTHONPATH
echo $LD_LIBRARY_PATH

If PYTHONPATH is empt you can set

export PYTHONPATH=/usr/local/lib/python2.7/dist-packages/
Otherwise you have to append this string to PYTHONPATH

Find the location of libgnuradio-afsk.so in your /usr/local directory and append or set your LD_LIBRAR_PATH to the directory where the lib is located.

Dear Volker, My hearty thanks to you.. You have save my day... I was breaking my head for the past three week to solve this problem. With you kind help i have successfully compiled your example... Now i have connected my RTL-SDR usb dongle and i have created a grc file in GNURADIO to receive FM Radio Stations (Eg. 106.4 Mhz) and it works nicely. When i try to receive the signals from HT Beofeng UV-5R ( Freq @ 136.025 Mhz) the audio is very low and very much distorted, but i tried using Gqrx and Direwolf Softwares which are giving very clear audio output. Dear Volker, sorry to disturb you again, I have attached my grc file, can you please correct me, where i am doing wrong...If i receive clear audio from my Beofeng HT, i am sure i will receive the APRS Packets correctly... This is my kind request.... Thank you sooooooooooooooooooo much.

The grc file is missing.
gqrx is a good way to check the dongle.
Try to set the same gain settings in your flowgraph that you use in gqrx.

A common reason for bad audio output may be wrong sample rate settings or inappropriate filter bandwitdh settings.

Dear Volker, Thanks for your reply... Here is my FM Receiver's GRC File... This GRC file is working good for local FM Radio Station (88Mhx to 108Mhz).... But when i try to receive the HT Signal (136.025Mhz), the audio is not clear... I hope if you can go through the file, you will find the problem... Thanks a lot for spending your valuable time...

Sorry, but the grc file is still missing. I think you can't attach a file. You have to upload to github.
