Unfortunately when using hf the link audio quality is very poor.

Aircraft can use radios operating in the hf radio band for long range communications as the signals are reflected by the ionosphere. The corresponding half wavelengths of these frequencies are 3 96 3 44 feet 47 5 41 2 inches. It includes the following. Radio communications are a critical link in the atc system.

Discussion herein provides basic procedures for new pilots and also highlights safe operating concepts for all. Radio tuning system. Vhf radio frequencies used by aircraft communication radios are 118 136 975 mhz. Audio integrating system.

The link can be a strong bond between pilot and controller or it can be broken with surprising speed and disastrous results. The system is also responsible for recording communications and cabin audio. Today aviation communication relies heavily on the use of many systems. Therefore vhf antennas are relatively long.
