These amateur radio repeaters provide a very valuable service to many stations, and in particular those that do not have particularly good locations or those amateur radio stations that are using only low power. A repeater, whether an amateur radio repeater or even a commercial repeater is a station that receives a signal on one frequency and simultaneously re-transmits it on another. Repeaters are sited in good locations with good coverage enabling stations that can access the repeater to be heard on the output and thereby take advantage of the location of the repeater. Effectively it gives the low power amateur radio station the same coverage as that of the repeater. In this way radio hams using small handheld transceivers, or those using mobile equipment in a motor vehicle are able to make many more contacts than they would otherwise be able to do. A ham radio repeater is essentially a relay station that receives a signal on one frequency and retransmits the audio on another.

In times of crisis and natural disasters , amateur radio is often used as a means of emergency communication when wireline , cell phones and other conventional means of communications fail. Unlike commercial systems, Amateur radio is usually independent of terrestrial facilities that can fail. It is dispersed throughout a community without "choke points" such as cellular telephone sites that can be overloaded. Amateur radio operators are experienced in improvising antennas and power sources and most equipment today can be powered by an automobile battery. Annual " Field Days " are held in many countries to practice these emergency improvisational skills. Amateur radio operators can use hundreds of frequencies and can quickly establish networks tying disparate agencies together to enhance interoperability.
Talk:Amateur radio repeater
Within a local or regional area, many ham radio repeater systems may use remote receivers that relay weak signals from outlying areas back to the main repeater transmitter. The relayed signal is transmitted over a control link, which is a dedicated transmitter and receiver operating on a VHF or UHF band. To link repeaters over wide areas and long distances, however, it is common for repeater systems to use the Internet.
As of 20 April , all QSL cards have been sent out to stations that have sent me a card. I've also responded to all cards received via the QSL bureau, but they may still be enroute.
