The Frequency can be adjusted via the FFT Plot that opens when the script is started

It uses a fifo (create it with mkfifo and change the File Source box in GNU Radio Companion accordingly). You can feed it with mp3 by executing, for example: mpg123 -r41000 -s foo.mp3 > /path/to/input_fifo. You can change the broadcast frequency by modifying the osmocom Sink configuration in GNU Radio Companion.
