FM (frequency modulation) is what you hear on 2 meters when using a handheld and working through the club repeater. It is the mode where most hams begin. FM has exceptional quality for voice communication and there is generally no noise or fading that you hear on HF with SSB or CW. However because of its wide bandwidth requirements it is usually limited to bands such as 2m or 70cm where there is lots of room. Some FM can also be heard on 10 meters around 29 MHz.
