Looks like you're using a gmsk modulation [...] > What I am trying to do now is to transmit whatever I play on the > computer (songs) and receive it on a regular FM radio in the room.

If you want to receive the audio on the FM radio, you probably should transmit in wfm, not using an gmsk modulation (which is a digital transmission). The blks2/wfm_tx block should do. -- Best Regards, ChoJin _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
