TRANSCEIVERS - SECTION 2 (FLIGHT RADIO PPL)

An aviation TRANSCEIVER is a specialized, two-way radio communication device that combines a TRANSMITTER and a RECEIVER into a single unit, allowing pilots to both send and receive voice messages over specialized aviation frequencies

A Transceiver is a composite (compound) word, meaning something that is both a…

TRANSmitter and reCEIVER.

A transceiver can:

transmit and receive radio waves.

Aircraft are fitted with transceivers which can operate in the:

Very High Frequency (VHF) band

To turn the radio on,

the electrical master switch needs to be on. Some aircraft will have an additional avionics power switch which will also need to be switched on.

The Squelch control, usually incorporated into the volume knob of a radio set (you pull out the knob to adjust the squelch), is used to..

eliminate any unwanted noise, like static.

• When turning the squelch up, less noise is filtered. If you turn the squelch down, you will gradually eliminate more and more unwanted signals.

When transmitting, you should listen to ensure that..

no one else is transmitting. If you hear someone talking, wait until they are finished.

If you have the correct frequency checked and right settings on the audio panel but still have an issue, you should….

..you should double check the master and avionics master switches are on, as well as volume. Check the circuit breakers, as an electrical overload may have caused the radio circuit breaker to pop out.
