Shortwave

Shortwave

Shortwave radio refers to frequencies in the HF spectrum that can be used to broadcast over long distances. Unlike local AM and FM radio stations, shortwave signals can travel thousands of miles, making them an important tool for international broadcasting and communication.

Shortwave is used by broadcasters, amateur radio operators, and emergency services to reach remote areas and establish communication without relying on the internet or telephone infrastructure.

Shortwave Examples

  1. International Broadcasting: Shortwave radio is used by international broadcasters to reach listeners worldwide. These broadcasts can provide news, cultural programs, and emergency information, often reaching places where other forms of communication are unavailable. Learn more about Shortwave International Broadcasting.

  2. Listening to Amateur Radio: Shortwave receivers are often used to listen to amateur radio operators communicating on HF bands. This is a popular activity for both hams and shortwave listeners (SWLs) who enjoy exploring the airwaves and learning about different operators and countries. Find details on Shortwave Listening.

  3. Emergency Communication: Shortwave is also used for emergency communication, providing a way to communicate when other systems are down. It is particularly valuable in remote or disaster-stricken areas where infrastructure has been damaged. Read more about Shortwave Emergency Communication.

  4. Utility Stations: Utility stations, such as maritime and aviation services, use shortwave to transmit important information. These broadcasts can be listened to by anyone with a capable receiver, providing an interesting look at how shortwave is used beyond amateur radio. Discover more about Utility Shortwave Stations.

Local Club Activities

RARS sponsors a local Shortwave Special Interest Group (SIG) called the
