 * \brief RadioStation Click example
 * 
 * # Description
 * RadioStation Click can be used to broadcast the music via the FM radio band 
 * ( which operates in the frequency range of 76MHz to 108MHz ).
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - I2C and sets transmit_frequency.
 * 
 * ## Application Task  
 * In this example Radio Station Click is receiving signal from audio connector and broadcasting 
 * it on 100.00 MHz frequency.
