Useful Bits If a controller gives you instructions e.g. a clearance you must repeat exactly what they say. If a station has a call-sign with either ‘Information’ or ‘Radio’ they are not a controller and will not give instructions just information. Do not start talking until you have the button pressed or until you know what your going to say. If the radio goes very quiet… check you don’t have the transmit button pressed or the squelch turned down too much. Radio Waves travel in straight lines, so be aware ground features will affect your ability to transmit.
