How does a radio repeater work?
A repeater is a station that receives incoming signals and retransmits them on a different frequency. … Repeaters can be linked together to extend their range even further. This linking can be done by link transmitters and receivers installed at the repeater. It can also be done by landline or Internet connection.
How do you listen to a repeater?
How to listen to repeater contacts
- Use a repeater directory or website to find a repeater in your area.

- Set up your radio to listen on the repeater’s output frequency. …
- Tune your radio as you do for FM signals.
How often do repeaters identify?
You will also typically hear the repeater identify itself with either Morse Code tone patterns or by recorded or electronic voice ID at least every 10 minutes.
How far do repeaters work?
Repeaters within signal range of each other cannot transmit on the same frequency and PL tone without causing interference. Repeater range is roughly 25 miles. Areas of higher network usage require more repeaters than areas of less network usage in order to provide coverage for all operators and minimize interference.
What does a radio repeater look like?
A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. … Some repeaters use two different frequency bands to provide isolation between input and output or as a convenience.
Why would you need to use a repeater?
In telecommunications, a repeater is an electronic device that receives a signal and retransmits it. Repeaters are used to extend transmissions so that the signal can cover longer distances or be received on the other side of an obstruction.
What is a repeater PL tone?
What is a PL or CTCSS Tone? PL, an acronym for Private Line, is Motorola’s proprietary name for a communications industry signaling scheme called the Continuous Tone Coded Squelch System, or CTCSS. It is used to prevent a repeater from responding to unwanted signals or interference.
How do you use a linked repeater?

What are repeater stations?
Radio Repeater Station
A repeater is an automated radio station that extends the range of communications. It consists of a receiver tuned to one frequency and a transmitter tuned to a different frequency, linked together with a controller device.
What is a PL tone in ham radios?
