[Discuss-gnuradio] Dream (for Digital Radio Mondial) transmit FIFOs

Some very generous folks on this list have pointed me towards how to do
a DRM receiver with the USRP and Dream via FIFO's and a nifty little
piece of python code. Unfortunately, I live smack dab in the middle of
the US with nothing but a random wire antenna. The Dream code lacks the
ability to write to a fifo/file instead of /dev/dsp.

My goal (for testing) is to run DRM in transmit mode over the LFTX board
and then receive it on the LFRX with a short patch cable, then later
move up to an antenna for some short range tests in a Faraday cage.

Has anyone tackled this problem (on linux) before? Is there a nifty way
to be able to let drm -t suck in from the soundcard as usual, but output
to a fifo and then have some python code dump that to the usrp? I think
I've got the listening end accounted for thanks to you folks.

Any help would be appreciated. I look forward to the code you are
working on for DAB/DRM.

Thanks in advance!
