Microlight » Flight Radio » Transceivers
Aircraft are generally equipped with at least one communications radio set operating in the Very High Frequency (VHF) range.
These radio sets are both a transmitter and a receiver and are called a Transceiver.
The items associated with the main transceiver in the cockpit are:
- Microphone used to transmit messages;
- Speaker/headset for listening to received messages;
- Master switch(electrical) to give power supply to the radio;
Microphone Techniques (PTT - Push To Talk)
- The microphone should be positioned directly in front of, and close to your mouth.
- To transmit your message, hold down the microphone transmit button fully on the control, pause and then speak.
- Finish the message, pause, then release the transmit button.
- Do not depress the transmit switch until ready to speak.
- Speak at a normal and slightly slower conversation level.
- It is not possible to receive messages while you are transmitting.
- While you are transmitting on a given frequency, no one else can transmit on that frequency.
- Make sure the button is released when finished transmitting.
- Think about what to say before you press the transmit button.
- Pausing between pressing the microphone button and speaking gives the radio time to stabilise the transmission.
