Re: [Discuss-gnuradio] about RDS and FM transmission

[Dimitris Symeonidis]

Hi Rafael, I'm the current developer of GR-RDS.

The RDS signal has to be mixed with the mono, pilot tone and stereo signals BEFORE fm modulation.

Also, be aware that the transmit path is not working yet, I'm debugging it when I have some spare time to fix it. Any help is welcome.

You should use the BasicTX daughterboard.

Hi people,
I'm a volunteer of a free radio here in my city (Campinas), and looking at
CGRAN I found a RDS receiver/transmiter:
https://www.cgran.org/wiki/RDS

Can I modulate only the RDS data using this gnuradio software and then,
inside the FM transmitter, between the exciter and the power amp mix the
RDS signal together w/ the FM signal?
They have to be at the same power level to be mixed, right?

Do anyone have any experience w/ that?
What daughterboad to use (FM band)?

Thanks in advance,
Rafael Diniz
