Re: [Discuss-gnuradio] flowgraph for commercial FM radio TX/RX

[Steve Mcmahon]

Hello Bernardo Gonçalves:

No, I have not yet obtained any other materials/flowgraphs other than what 
Markus Heller posted on this mail list. However, I do not have time to look 
into the FM radio TX/RX right now as I am very busy trying to finish something 
else. I will start working on it again in about one week. Let's talk again at 
that time. Have you found any other materials? I would be interested in 
collaborating with you on this. Are you trying to do the same thing that I'm 
trying to do (create a flowgraph for TX and/or RX of commercial FM radio)?

You also asked about other non-FM-radio flowgraphs. I do have some other 
flowgraphs that I would be happy to share with you. What are you looking for?

By the way, in the USA, commercial FM is on odd frequencies (i.e., 94.5 MHz, 
94.7 MHz, 94.9 MHz, etc.). In Europe and Japan, isn't commercial FM on even 
frequencies (i.e., 94.4 MHz, 94.6 MHz, 94.8 MHz, etc.)? Where are you located? 
I am in Boston, Massachusetts, USA.

Hello Steve,
I have read your email a long ago and since I am working on similar stuff (only 
for simulation purposes), I would like to know if you got some other materials 
with other flowgraphs. I know that Markus Heller answered your email with his 
website, but I am looking for more.

Do you have any other flowgraph (not only FM ones)?
Thanks!
Regards,Bernardo

Hello:



Does anyone have a flowgraph that could be run on a USRP2 with a WBX 
daughterboard for either transmit or receive of commercial FM radio (88 MHz to 
108 MHz U.S.)?



In the transmit case, I would like to read raw PCM audio from a file and 
modulate it and transmit it in the commercial FM band, to be received by a 
standard FM radio.



In the receive case, I would like to capture and demodulate commercial FM radio 
and save the raw PCM audio data to a file for playback.



This is for academic, proof-of-concept, very low-power purposes. I am not using 
it to operate a pirate FM radio station.



I appreciate your help.

Thanks.
