Band 3 baseband player

Freechelmi:

CRC-Dwap.py has got some problems with recent versions of Ubuntu (using new wxpython version) and gnuradio (change in the library calls).

A new baseband player for USRP1 has been designed and that is now compatible with recent Ubuntu versions. This player also include:
*A pre mask filter to respect DAB mask spectrum (however a hardware mask filter is still needed after amplification)
*Output spectrum display
*Channel selection in VHF band 3

===Source files===
* Python script: [http://www.opendigitalradio.org/files/band3_usrp1_player.py band3_usrp1_player.py]
* Gnuradio Companion graph (used to produce python script): [http://www.opendigitalradio.org/files/band3_usrp1_player.grc band3_usrp1_player.grc]

===Usage===

This tool requires no argument and is just inserted at the end of the (pipe) chain. It takes samples at 3.2MHz as standard input and send this stream to the USRP1.
It is possible to change the frequency on the GUI interface and filter activation or spectrum display.

Please note that the activation or de-activation of these functionalities causes interruption of the transmission.

''This is Work in Progress !''

This is the setup for teh launch of DAB/DAB+ broadcasting of the [SDN] mux including [Radio Galere] in Marseille France.

This is done on Ubuntu 12.04.1 64 bits using a USPR1 with a WBX daugther card. Our mux is using the 5C frequency.

= Installation of components =

== Etti drivers for USRP1 Card ==

This will add the etti deb source and install the uhd package that contains the driver :

'''sudo bash -c 'echo "deb http://files.ettus.com/binaries/uhd_unstable/repo/uhd/ubuntu/`lsb_release -cs` `lsb_release -cs` main" > /etc/apt/sources.list.d/ettus.list'
sudo apt-get update
sudo apt-get install -t `lsb_release -cs` uhd'''
