What is an amateur radio repeater?

The

amateur radio repeater is a piece of equipment used by amateur radio operators to amplify the radio frequency signals (RF), which allows operators to communicate further than radio radio radio transmission. In addition to sound, some types of repeaters can pass on images and television broadcasts. Nations can regulate the use of amateur radio repeater. In addition, the receiver, driver and transmitter are an integral part of this device. The radio signal is picked up by an antenna. It is then transmitted to the supply line, which is a cabling that connects an antenna with a duplex. This type of cable is often a "hard" line, has less signal loss than a standard coaxial cable. The receiver rewrites the signal to the sound and sends it to the controller, a small computer that prepares the repeater. From the controller, the sound is transmitted to the repeater transmitter that modulates the sound and increases its strength. The output is sent back to the duplexer via the feed line and finally through the antenna. Repetition is usually found on hills or on top of buildings or towerbecause these types of places tend to improve the repeat range.

The

repeated device usually compensates for amateur radio repeater frequencies, so the received and transmitted signals are at different frequencies to maintain the signals separate. National organizations can coordinate amateur radio repetition frequencies to reduce interference. The listings for the placement and frequency of repetition stations can be found in amateur radio repeaters.

There are several types of amateur radio repetitions. Simplex repetition does not dare the frequency of transmission; These can be called parrot repeators. Repeat of the same belts use separate antennas to receive and transmit a separate antenna. Digipeaters can be used to communicate between computers using the same frequency to receive and send data.

amateur radio repeaters can receive more sophisticated tasks than just audio transmissiony. To send a video, you can use SSTV repetition to hand over graphics and special repetition of amateur television (ATV). Amateur satellites can use the transponder repeates.

The

amateur radio operator may also want to understand the label of the repetition company before attempting to transmit by one. The amateur radio can be used for emergency reporting and operators may have to allow these transmissions to be passed immediately. National regulations can also be disposed of using repeater, for example, allowing only licensed amateur radio operators to hand over by repetition.
