[Discuss-gnuradio] Can I do this?

[Jorge Chávez]

Hi gnuradio's

I'm trying to FM TX, can I do this with the fm_tx4.py:

address@hidden:/home/gr-build/gnuradio-examples/python/usrp # ./fm_tx4.py -c 98.7
 
When I run it I get this:

address@hidden:/home/gr-build/gnuradio-examples/python/usrp # ./fm_tx4.py -c 98.7 ddc_freq = 98.7
len(interp_taps) = 356
>>> gr_fir_fff: using SSE
len(interp_taps) = 356
len(interp_taps) = 356
len(interp_taps) = 356
TX d'board A: Basic Tx
TX d'board B: <none>

But I can't hear in a Radio (98.7MHz) what I record in audio-0(-4).dat

What am I doing wrong?
what is missing?
I'm thinking that it yust work for 29.326MHz, but my convencional radio system is not alowed to do this frecuency.

Thanks for your answers, and sorry for my english..
