What Amateur Radio Is Radio station design and construction Specialized and Advanced Activities – Contests, Awards, and Special Events – Satellite communications (amateur satellites, shuttle, ISS), microwave and “Moonbounce” Field Day, QSO parties, etc. Public Service—A tradition in amateur radio – Provide emergency communications (natural disasters, civil defense and homeland security) – Public event communications (races, parades, etc. ) – Military-affiliated radio services (MARS)
Amateur Radio is not. . • Broadcasting (as in your local TV or FM radio station) – – • Amateur radio uses two-way communication Still, hams enjoy listening to intl. shortwave “CB” (non-licensed, limited radio service) – – “CB” is informal, at times bordering on “R”-rated! – – “CB”; a narrow band of freq. ~ 27 MHz Ham's abide by on-the-air operating practices established over many years Amateurs have frequency allocations from 1. 8 MHz to 20 GHz and beyond!
Amateur Radio Operator's Communicate Radio communication using a wide variety of “modes” Voice (called “telephony”) Digital (using computers with a radio “link”) Morse code (many reasons hams still use code!) Television (“slow-scan” and “fast-scan”) Many other specialized sub-categories
Amateur Radio Operator's Communicate And a variety of frequencies! Amateur Radio is allowed on a wide range of radio frequencies; 1. 8 MHz to light! HF (“high frequency”) or “shortwave” very popular, useful for long range communications, in fact all over the world! VHF/UHF for local communications Microwave (local and satellite)
Ham Radio Can Be. . . As technical as you want it to be! Some Ham's buy radios, antenna, etc. Other's build. . . Many hams still build all of their radio receivers, transmitters, and other station hardware including antennas! “From scratch” or from kits Great way to obtain a more intuitive hands-on understanding of electronics Most do both!
The Amateur Radio Club at UCF Membership in the Amateur Radio Club at UCF provides a venue: To explore amateur radio To participate in fun activities To meet and exchange ideas To discuss questions about the technology and to practice amateur radio operation.

Do I need a License? • Yes and No! – – • You DO NOT need a license to build equipment and antennas or receive amateur radio signals You DO need a license in order to transmit (send signals) on any amateur radio frequency The ARC@UCF encourages everyone to get their amateur radio operator’s license. – – Enjoy all the benefits of amateur radio – “Do I need to learn Morse code to get my license? ” No, but feel free to learn CW! It is not difficult, all it takes is a little time to study
