What is a Repeater?
A repeater is a radio station that receives transmissions on one frequency and simultaneously retransmits them on another frequency. This greatly extends the range of handheld and mobile radios. Repeaters are invaluable for:
- Extending the range of portable radios to 50+ miles
- Connecting with other operators across a city or region
- Emergency communication
- Net operations and local club activities
How to Use a Repeater
- Program the repeater frequency pair into your radio (input and output frequencies)
- Set the proper tone (CTCSS). Most repeaters require a subtone to access
- Listen for activity to understand the local repeater culture
- Key up and identify: "This is [callsign] listening on [repeater name]"
- Wait for acknowledgment before starting a conversation
- Keep transmissions brief and professional
- Always identify at the end with your callsign
