Flowgraph for commercial FM radio TX/RX

Hello:

Does anyone have a flowgraph that could be run on a USRP2 with a WBX
daughterboard for either transmit or receive of commercial FM radio (88
MHz to 108 MHz U.S.)?

In the transmit case, I would like to read raw PCM audio from a file and
modulate it and transmit it in the commercial FM band, to be received by
a standard FM radio.

In the receive case, I would like to capture and demodulate commercial
FM radio and save the raw PCM audio data to a file for playback.

This is for academic, proof-of-concept, very low-power purposes. I am
not using it to operate a pirate FM radio station.

I appreciate your help.
Thanks.

Hi Steve,

on my webpage I collected a number of receive and transmit flowgraphs
for all sorts of modulations, but also FM:

I also own the USRP2 and the WBX board and I am testing them step by
step.

Please also consider these documents:

For a nice receiver there’s this neat little Python program from Michel
Barbeau:

…which you might download right away with “wget”.
