Amateur radio Repeater
The two way radios feet and two feet lay groups are the most popular of all amateur and where most radio amateurs start. The two meter band is a band, VHF or very high frequency band cm 70 years is a band of UHF or Ultra High Frequency.
After obtaining an amateur radio license or “ticket” is usually an initial investment of ham in a double-hand dual-band radio frequency that often develops as a HT or a walkie phone, a term from the old expression: ” walkie-talkie. Investment in education amateur radio is a second two way radios, mobile phone dual-band UHF two way radios / VHF transceiver or “platform” which mount in your car or Radio Shack. Both teams have very similar features, but battery Pocket generally limited to a two way radios maximum power of about 5 watts. two way radios The mobile phone is connected to the power source of twelve volt vehicles, or as a base station, a power converter 12 volt DC and is transferred to a position usually up to two way radios, 35 watts.
UHF and VHF frequencies, line of sight. Depending two way radios on the output power and the location of the transmitting antenna UHF and VHF transmissions are able to reach the visible horizon, maybe just a little further, but it is the limit. There is a notable exception to this rule is the troposphere channels, in rare and unusual weather VHF and UHF signals travel much further than the radio horizon. Amateur Operators two way radios use this phenomenon is caused by communication with other hams over long distances.
A 5 watt mobile-talkie is a field of action “based on terrain and elevation” of about 3 miles have. A mobile device with full power with a good antenna in a good location, you probably have a maximum range of 15:00 to 20:00 miles under favorable conditions. To work around this limitation in the range of radio amateur radio repeater, the use often by amateur radio clubs owned, but some are privately owned. These repeater two way radios to hear or receive automatically transmitted at a frequency and at a different frequency, it is often called a “department”.

A mobile phone talkie ham can be used to relay the input frequency transmitting and receiving the frequency output relay effectively the range of drilling a little above the horizon, perhaps even thirty or forty miles. Many systems have multiple receive antennas radio repeater in the distribution of repetition, yet is only a main transmitter. Thus, a large city are completely covered with a repeater system to radio receive amateur radio in the city and are likely to be received by the repeater or radio to “hit the repeater” radio, because it generally means a return to almost anywhere the city.
Recently, some repeaters connected to the world on the World Wide Web and can be connected through the World Wide Web. two way radios For example, Amateur Radio in Moscow, Russia with a mobile phone can walkie-your local repeater with a guy who likes to drive the car in the two way radios city of New York, United States, to chat.
Some radio repeater systems continuously connected to each other, but most are to the need by the user and the connection dropped at the end of the conversation.
Most repeaters are open free to all licensed amateur radio ham. Radio repeater to buy money to operate to maintain. They are financed mostly organized by the contributions of club members and club events as Hamfest. If the ham is a radio frequency repeater is perhaps what you really should consider joining the club, its repetition and contribute to its funding.
