kantoaaltosignaaliin

Kantoaaltosignaaliin, often abbreviated as KAS, is a type of radio signal used in maritime and aviation communications. It is a continuous wave signal transmitted at a frequency of 2182 kHz, which is within the shortwave band. The term "kantoaaltosignaaliin" translates to "high-frequency signal" in Finnish.

The primary purpose of KAS is to provide a reference signal for the automatic direction finder (ADF) systems used in aircraft and ships. These systems help navigators determine their bearing relative to the transmitter. KAS is particularly important in areas where other navigation signals, such as those from non-directional beacons (NDB), may be weak or non-existent.

KAS transmitters are typically located on coasts and in other strategic locations to ensure widespread coverage. They operate continuously, 24 hours a day, to provide reliable navigation assistance. The signal is strong enough to penetrate buildings and other obstacles, making it a valuable tool for both commercial and general aviation.

In addition to its navigational role, KAS can also be used for other purposes, such as testing and calibrating radio equipment. Its continuous nature and predictable frequency make it a standard reference in the field of radio communications.

Despite its importance, KAS is not without its challenges. Interference from other signals and natural phenomena can sometimes affect its reception. However, with proper tuning and location, KAS remains a reliable tool for navigation and communication.
