Re: [Discuss-gnuradio] Noob question 1

Hi Jan
Believe me, I am reading the tutorials, also the youtube lessons https://www.youtube.com/watch?v=N9SLAnGlGQs

But for me it is easier to understand basics when there is a basic working layout available. There is so much about GNURADIO
out there that a noob also needs some help with the help. (lol).

I am not a technician, developer or electronic engineer so the learning curve is steep.

Thanks for your replay and links.

When the RTL works I will post the layout here for others.

Best regards

Hi Henk,

I suggest you start with the guided GNU Radio Tutorials [1]. They contain the basics to work with GNU Radio.

In Tutorial 6 it is explained how to use a hardware source (USRP, RTL Dongle) with the audio sink [2]. But I suggest finishing the other tutorials first if you have no experience with GNURadio.

Cheers and happy hacking,

Jan

Hello all
4 weeks ago did my first steps into Linux Ubuntu.
I am trying to get the RTL-Dongel to work but still not succeded in that,
Time to ask some help.
There is a image with pre-installed drivers and GNU-Radio companion,
http://gnuradio.org/redmine/projects/gnuradio/wiki/GNURadioLiveDVD
I have downloaded that and put it on a USB stick. Works fine.

In the terminal I enter rtl_sdr -t and the RTL-dongel is found and it works.
Then I start GNUradio companion, it is version 3.7.7.1. The RTL is found in
the sources.
But the radio has a blue output and the audio-sink a orange one. In the
Help-doks it says that this is because of the datatype
but I cant change that anywhere. The dongel properties-block gives "complex
float 32".

Can you help me getting it to work? Only with a working system I can go
further learning.

Thanks

Henk
