[Discuss-gnuradio] Some help required piping samples to the USRP2/WBX

[Charles Brain]

Hello,

I am trying to write a python script which will 
allow me to take some 16 bit IQ samples 
from a file and write them out to my USRP2/WBX.

The background is that I am trying to implement 
what has been done on here 
http://www.m0dts.co.uk/datv_live.htm

but instead taking the output of gbDVB piping it through
an app I am writing (to do the raised cosine filtering) then 
piping that to the USRP2

Unfortunately GnuRadio is a bit daunting at the moment
especially finding what various things are especially as some usrp
blocks don't seem to exist for the usrp2 or their input formats are
different.

What I need to do is set the tx frequency to 1249 MHz
select the correct antenna output then pipe samples from
the input file to the usrp2 sink.

Any pointers would be most useful.

Be gentle
