WHY do we need this? Situational Awareness - What is happening to you andyour neighbors A Common Operating Picture - What is happening onthe island or in the state Resiliency - What are the immediate needs of ourcommunity and neighboring communities

Why do we prac)ce? Learning what simplex is like Turning down or off squelch for weak signal reception Using high power Learning where you can and cannot reach –capabilities and limitations of your station and others Gaining a visual of where all the players are Getting to know the players and their demeanorduring operation Tuning and improving radio and antennaperformance
