The file I used to grab the Radio2 signal (89.8Mhz)
with was ursp_rx_cfile.py (no 5.75Mhz IF mentioned)
with decim=200, dcc-freq=31.3e6. The wfm_rcv_file.py
was used to recover the audio from the generated dat
file easily.
Now, with wfm_rcv.py working and set to the same
settings as usrp_rx_cfile.py I cannot recover the
audio. I can still see the waveform in usrp_fft.py so
it is still there.
Am i missing something obvious?
Also, the max ddc for usrp_fft.py is 32e6 so i'm
assuming the maximum usrp rf frequency is 32Mhz??? and
the Radio2 wfm reception i'm receiving is some
harmonic. With the standard daughterboard how can i
receive 433MHz for example?
thanks
