Hello Bernardo G.:
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.
