This is to confirm that the repeater has reset the timeout. “K” – When someone stops talking and releases the transmit button, the repeater sends out a “K” (Morse code: ‘dah-di-dah’).Some repeaters have a timeout of only 90 seconds, to encourage users to keep their ‘overs’ short. Timeout – Most repeaters have a timeout to guard against people keeping the repeater open for too long.You will often hear “station acknowledged” or “break acknowledged”, meaning that your request to talk has been heard and you will be ‘brought in’ shortly. Often you will hear “break”, which is meant to be used to indicate that you have a priority message. The next person to speak should bring in the station to let them send their message or join the chat. Joining a conversation or a net – Those looking to join in an existing conversation on a repeater will normally wait for a pause between ‘overs’ and then break into the conversation by giving their callsign.Many people do use repeaters at home, but you should always give priority to mobile users who need to get a call out, and leave pauses so that others can get in. Repeaters are primarily for mobile-to-mobile use.Instead, if you’re looking for a contact, say something like: “M6ABC listening for any calls” Calling “CQ” on a repeater is generally not done.Using a repeaterīefore getting started with repeaters, it’s a good idea to have a listen to your local repeaters to see which ones are active, and what the etiquette is for using that repeater. It’s also important not to set the ‘mic gain’ too high, or if you have a loud voice, to talk too close to the mic, or shout. When programming your radio for a 2 metre voice repeater, you would normally want to set the Bandwidth to “Narrow”, and not “Wide”, to help reduce the risk of over-deviation. Over-deviating: Transmitting with too much audio energy / volume will result in over-deviation, and the audio ‘clipping’ and not being completely readable. Once you have the settings correct, save them to a memory on the radio for easy use next time. Only then will the repeater let you pass a message.
You need to program your radio to switch from the Output to the Input frequency when you push the Transmit button, and to send the correct identifying tone. The CTCSS Tone: This is required to allow your signal to be forwarded by the repeater.GB3DA, the Danbury repeater, transmits on 145.725MHz (the Output), and listens on 145.125MHz (the Input).For 2m repeaters, the offset is normally 600kHz below the Output frequency.
The Offset: The difference between the Output and the Input frequencies (either a positive or a negative frequency).Output Frequency: The frequency that the repeater transmits on, and you listen on.To access a repeater, go and find your local repeater, then note the following settings, and program them into your radio: Many find it easier to get a cable and connect the radio to a computer to use that for programming, as it’s often easier than the fiddly on-screen menu on the radio.

How this is done varies with each radio, and you will need to refer to the manual, or chat to someone familiar with that radio to work out how to enter and store the settings correctly. Only one person should transmit at a time, otherwise the signals will overlap.īefore you can use a repeater, you will need to programme your radio with the settings for that repeater. If it hears a valid signal, it will re-transmit the signal on the Output frequency. A repeater listens on a particular frequency, called the Input frequency.

How does a repeater work?Ī repeater can receive a weak signal, or a signal from a portable user, and re-transmit it over a wider area.

There is a comprehensive list of all of the UK’s repeaters at – Here, you’ll find some advice on setting up and using a repeater, plus some common terms. These are commonly on 2 metres and 70cm, although there are repeaters for other bands and modes. The UK has a network of around 300 amateur radio repeaters.
