The core questions: Should amateur radio —and its precious spectrum—be protected purely as a hobby, or is it a utility that delivers data traffic? Or is it both? And who gets to decide? Since Kolarik filed his petition in late , this debate has engulfed the ham world. Fierce defenders of both sides have filed passionate letters and comments to the FCC arguing their cases.
Amateur radio frequency allocation is done by national telecommunication authorities. Globally, the International Telecommunication Union ITU oversees how much radio spectrum is set aside for amateur radio transmissions. Individual amateur stations are free to use any frequency within authorized frequency ranges; authorized bands may vary by the class of the station license. Radio amateurs use a variety of transmission modes, including Morse code , radioteletype , data, and voice. Specific frequency allocations vary from country to country and between ITU regions as specified in the current ITU HF frequency allocations for amateur radio. The modes and types of allocations within each frequency band is called a bandplan ; it may be determined by regulation, but most typically is set by agreements between amateur radio operators. National authorities regulate amateur usage of radio bands.
As a Technician licensee, you have free access to all amateur frequencies above 50 MHz, but what about on the shortwave high-frequency HF bands? This chart helps you follow the rules. You have many more frequencies to use on the high-frequency HF bands, as shown in the following table. A complete chart of the U. Hams use three-letter Q signals on every mode and even in face-to-face conversation.
