Re: [Discuss-gnuradio] Transmitting a file (txt,

[meggahertz]

Hi Juha! Thank you so much for your tremendous help. I looked at your code and 
using part of your fmradio.py code, wfm_tx.py and fm_tx4.py I put together 
something similar and am now able to transmit using my microphone and anything 
through my sound card. I am facing one problem, when I received the sound in an 
FM Radio, it comes out funny as in the pitch is low. So I tried changing the 
"audio_rate" and making it 50KHz, which makes it sound better but not perfect 
and has clicking noises. I believe the soundcard I am using (Creative SB  
Audiy2) has a sample rate of 44100Hz I think. Might be 48000Hz. Either way, and 
I can't make the audio_rate close enough. I am basically just getting the 
packets from the audio source and putting it in the code like below inside 
class 'wfm_tx':

"           self.fg = gr.flow_graph()
            src = audio.source(44100, options.audio_input)
            fmtx = blks.wfm_tx(self.fg, self.audio_rate, self.usrp_rate)
            self.fg.connect(src, fmtx, gain, self.u)" 



Is there a way to make it exactly the same or make it sound perfect on the 
radio? Your help would be appreciated like always. 

Thank you,
Omer
