Hello all (asking for some help)

GNU Radio
1

I know it will sound strange since for the last day that I have been
subscribed to this list I can see many advanced (at least to me) topics
but I am new to it, I have just purchased the USRP motherboard and I
have many many questions. To start with the more simple ones, I would
like to ask what are the steps I have to take to install the software.
I am planning to use the USRP card as a data acquisition system,
sampling I, Q channels and passing them through the USB and record them
on a hard disk.
What software do I need to install and where to start from? My
understanding until now is that I better go with Linux since Windows
platform seems to have some incomplete patches yet.
I suppose that first I have to check the dependencies of my operating
system that are required.
Then I have to download the gnuradio folder (from the stable release)
which includes the core programs in the folder trunk and install this
with all of its components.

Would that be all? Do I need to download a firmware for the FPGA as well
or does it come with preinstalled firmware?

I hope you can guide me around

thank you all

For those of you using ALSA and jack there may be immediate relief.

The ALSA jack plug slave PCM device and the aoss dspN devices
appear to work together without incident. So, if you put the
following in $HOME/.asoundrc:

pcm.jackplug {
type plug
slave { pcm “jack” }
}

pcm.jack {
type jack
playback_ports {
0 alsa_pcm:playback_1
1 alsa_pcm:playback_2
}
capture_ports {
0 alsa_pcm:capture_1
1 alsa_pcm:capture_2
}
}

pcm.dsp0 {
type plug
slave.pcm “jack”
}

you can run any ALSA-based program with jack using ‘jackplug’ as
the device. You can run an OSS-based program under jack via oss.
For example, the digital mode program gmfsk can be run with
aoss gmfsk

This doesn’t solve all jack ills, but it does satisfy a number of
important cases without drastic rewriting or kludging.
