Amateur radio
Amateur radio à à à à à à à à à If regular communications were knocked out, Amateur Radio would be there to step in! Amateur Radio connects people in times of need during emergencies. à à à à à à à à à To start oneââ¬â¢s adventure into Amateur Radio, one needs to obtain a license. There is a test required by the FCC in order to obtain a license which one needs to operate an Amateur Radio (H10). Only licensed amateurs can operate an Amateur Radio station (BARTLETT). Amateurs have to go through the different levels of licenses, which go from technician to general then to extra (HARING). With each step, they get more privilages and frequencies. Past exam questions included equipment, regulations, and morse code, all of which were dropped (HAMILTON). Now Amateur Radio is growing at a rate of 10% a year (HAMILTON). Amateur radio is growing with the new generation as well. ââ¬Å"Amateur Radio not just meant for old folks. The Amateur Community want to see a new g eneration of men and women try Amateur Radio,â⬠said Don Montgomery (CONRAD). Test and study materials add up to usually $40 (H11). à à à à à à à à à Amateur Radio is getting more and more in-sync with new technology and computers. Automatic Packet Reporting System (APRS) uses Global Positioning System with Amateur Radio to remotely track Amateursââ¬â¢ movements and reports them to the APRS website (H11). All one needs to use APRS is a GPS and an Amateur Radio (H11). Anyone can go online to the APRS website to see where amateurs are at, anytime of the day. Amateurs also use APRS for use with Geocaching (H11). Geocaching is a scavenger hunt where people use a GPS unit to find treasures outside (H11). Echolink can be used as an alternative to equipment. Echolink is a software program, which hams can use to listen to and transmit audio over the Internet (H10). Echolink works by using a computer and Internet connection with a radio to listen to the repeater, an d to constantly transmit audio over the Internet via Voice Over Internet Protocol (VOIP) technology to the end-user (H12). The same happens in reverse, when an end-user transmits they use VOIP technology to get to the computer, and the computer transmits audio to the radio, which the radio transmits audio to the repeater. With Echolink, licensed operators can get on other repeaters and listen and transmit on them as well (H12). There are conferences which are groups that can handle large amounts of users. These are server-based groups that are basically a middle-man or main group which people, links, repeaters, or other conferences can connect to (H12). Internet Radio Link Project (IRLP) is almost exactly like Echolink, except that it is made mainly for connecting only repeaters to repeaters via VOIP, and not for desktop clients (H10). Logging ones contacts for a record is important as well. There also is logging software which can log stations that amateurs have made contact with ( H10). Mostly logging is used with High Frequencies (HF) because of contesting. It is an easy way to keep track of oneââ¬â¢s data to send QSLs to (H10). Amateurs may also use an online log book, called Log Book of the World (LBW). This is useful for contacts that are in other countries (H10). If an amateur were to send QSL postcards to everyone whom they have had contact with in other countries, it would get really expensive, really fast (H10).
