154	154	le programme GNURadio ce trouve dans le lanceur ( logo ubuntu ), suffit de faire une recherche avec gnu, et il apparaît. Je le lance :

156	156
	588	+python 2.7.12 c'est aussi installé !
	589	+
	590	+{{info}}
	591	+C'est pas merveilleux LINUX !!
	592	+{{/info}}
	593	+
	594	+Je profite pour installer directement GQRX :
	595	+
	596	+~~$//sudo apt install gqrx-sdr//
	597	+
	598	+Ensuite je branche ma clef DVB-t, et je regarde si le programme GQRX la trouve.
	599	+
	600	+{{warning}}
	601	+Ma clef fonctionnait déjà ! sous SDR#
	602	+{{/warning}}
	603	+
	604	+je la trouve dans les entrées du programme :
	605	+
	606	+[[image:gqrx-iq.png]]
	607	+
	608	+Après scan, je trouve une radio sur 98,2 MHz
	609	+

	611	+== GNURadio ==
	612	+
	613	+En suivant l'excellent document qui se trouve :
	614	+http://f0fyf.blogspot.ch/2014/08/recepteur-fm-avec-gnuradio.html
	615	+je réalise mon premier programme SDR avec ma clef RTL-SDR.

	619	+[[image:DJtestDaarioSDR.png||height="545" width="562"]]
	620	+
	621	+
	622	+Normalement on doit pouvoir lancer directement avec le fichier python :
	623	+
	624	+[[DJTestRadioSDR.py>>attach:DJTestRadioSDR.py||title="fonctionne avec python 2.7"]]

	627	+[[image:testRadioSDR.png||height="358" width="599"]]
	628	+
	629	+
	630	+C'est confirmé ! depuis un terminal :
	631	+
	632	+~~$//python DJTestRadioSDR.py//
