[Discuss-gnuradio] fm_tx.py ??

[Jorge Chávez]

I need to transmit FM, I try the example fm_tx4.py from gnuradio-examples, but doesn't work:

address@hidden:/home/gr-build/gnuradio-examples/python/usrp # ./fm_tx4.py
ddc_freq = 29.325M
audio-0.dat: No such file or directory
Aborted


What is missing, where I get the file audio-0.dat?

Does anybody have a tested FM_TX, what I transmit, data?, signs from a microphone?, I'm pretty much lost.

Please help me...
