Hi there,
well gain i like to ask a short question. I did try to record some
signal in 27mhz. Its FM based.
I did it like this:
1st i modified usrp_tx that it saves the recording into a file called
audio-0.dat
/usrp_rx_nogui_to_file.py -f 27.195M -g 20 -m FM (tried it with rate
32000 and 48000)
2nd i try to replay the data using:
./fm_tx4.py -f 27.195M -n 1
I did have my radio scanner beside of me and can say from the sound
allready that the signal is deeper. (Akkustically)
so i guess its the samplerate. But no matter what i use it does not
seem to be right.
Just before i go nuts i hope that someone hase answers for the
following questions:
1) Did i do it correctly? Is there a better way to save and replay a
signal? Can you give me an example?
2) Was this modification correct?
diff usrp_rx_nogui.py usrp_rx_nogui_to_file.py
153c153,154
< AUDIO = audio.sink(options.output_rate, "")
---
> #AUDIO = audio.sink(options.output_rate, "")
> AUDIO = gr.file_sink(gr.sizeof_float,"audio-0.dat")
3) When i use ./usrp_rx_cfile.py -f 27.195M -g 20 --no-hb output.dump
i just get high frequent noise instead of the signal, thats why i
modified usrp_rx_nogui.
is there a way to record it using cfile corectly so i can replay?
Greetings
Max
