Repeaters are relay stations enabling reliable contact between radio amateurs over long distances using small portable radios and antennas. The repeaters use VHF and UHF frequencies that communicate over 'line of sight' paths from masts on hill tops. Their radio contact is limited by hilly terrain and the curvature of Earth. Besides each having its own local coverage area some are linked, by the internet, to other repeaters anywhere in the world and can be accessed by repeaters in other countries.
Repeater use is limited by the same regulations that apply to all licenced amateur radio ('ham') activity. In the UK they are 'open' and may be used by any licened radio amateur.They are maintained and funded by voluntary contributions by their users.
'Open' means free for all to use. Radio Amateur repeaters in the UK are not permitted to use selective identification or access codes. Repeaters are communication devices. Their function is not to provide entertainment and the relaying of music is prohibited. Amateur Radio Broadcasting other than by the special Notice of Variation for GB2RS operators is not permitted.
Repeater users become a community of individuals and groups who share the same air space. They acknowledge each other but tend to form separate groups. It is very like a public lounge bar with tables. There is no real privacy but one respects other people's space. Everyone knows that everything they say can be heard by everyone else, that is the point of a repeater! Conversation topics are somewhat limited and some are off limits. It is unusual for legal calls to be unanswered. The repeater is automatic, but the operators are not. We are people. We have limitations, minds of our own and free will. Good behaviour is required and generally rules.
I say 'legal call' because it is required. I have mentioned the 'licence'. All governments, world wide, issue licences for amateur radio communication. It is managed, world wide, for the benefit of all and is (in theory) a truly international activity. If you have a licence you have a legal callsign. It is a licence requirement that you identify yourself. The amateur radio licence only permits communication between licence holders. If you do not use your legal callsign you will not get replies.
At the moment (March 2026) we are experiencing probems with calls that do not include a callsign. The caller says one word only 'break'. Sometimes it is repeated. This style of operation is recognised as fairly normal by operators who use CB radio. It is one way of making oneself known and indicating that you wish to join a conversation.
'break' has no place in Amateur Radio.
A callsign says it all. We know what is intended and it is usual to invite 'the break station' to call again, using a callsign. Lack of etiquette is one thing, deliberate disruption is quite another. When the 'break station' does not respond offence is caused and hackles rise.
We are now advised to make no response at all to any caller who only says 'break'.
Our current practice is for a caller using a callsign to be acknowledged and invited to join the conversation after the current user ends his 'over'. To avoid confusion he is usually told who should follow him.
Every repeater user is expected to delay his transmission until the 'pip' tones indicate that the timer has been reset.
Repeaters have a built in timer. It has practical safety purposes and also discourages 'hogging' of the facility by those who like the sound of their own voice. The style of timer indication varies from repeater to repeater but it is usually in the form of two separated 'pips' or tones, or a single tone followed by a Morse character. I my immediate area the first tone is E (a single pip) and the second is I (a double pip) or R (.___.) or K (___.___). The space between them is intended to enable a new caller to join in. Every new transmission generates a single pip, and, after a short gap, a double pip, R or K. The timer is reset by the second pip or character.
In the event of interference some of us are able to force a repeater to reject an incoming signal and reset the repeater timer.
