Just over a year ago, a group of our friends were planning a trip to Walt Disney World. One major issue they faced was how to stay in communication with each other. Family Radio Service radios (which Byron discussed a few weeks ago) are nice, but their range is limiting. Our friends wanted to be able to reliably communicate between multiple resorts, not just within one park. Cell phones would work, however, as California residents with little need for nationwide coverage, using cell phones in Florida was not very efficient or affordable. In addition, cell phones work well for two- way communication but this group of 10 would need higher capacity for maximum efficiency. Two of the 10 already held Amateur Radio (nicknamed "ham radio") licenses. Several other members of the group studied for their ham radio test online and earned their licenses before going to Florida as well. The group enjoyed efficient communication for eight whirlwind days in Orlando!
What is Ham Radio? The Federal Communications Commission (FCC) licenses Amateur Radio operators to transmit and receive several types of communications (audio, video, Morse code, etc.) over certain radio frequencies. The level of your license determines which frequencies you can use. With a basic Technician license, operators can use all allowable frequencies above 50 MHz within certain "frequency bands" or groups. (Several frequencies are blocked for other types of transmissions, such as police radio, FM radio broadcasts, cellular phones). With the most advanced license, operators can use all FCC designated Amateur Radio frequencies. Even with just the Technician license, an operator has a wide range of radio frequencies to choose from, in addition to the very limited number of FRS "channels" or frequencies. Licensed operators are also allowed to transmit their communications with a lot more power than FRS radios, which are limited to 0.5 watts of power. This is enough to transmit over a couple of miles "line- of- site", where there is no obstruction, such as buildings, between the people using the radios. While hams are licensed to use up to 1500 watts of power for transmissions, most "handy- talkies" (hand-held radios or HTs) are capable of 5 to 6 watts of power, which is enough to transmit over many miles. More about Ham Radio Range Similar to FRS radios, ham radios can communicate directly with each other in "simplex" mode. In this mode, many hand- held ham radios can transmit as far as 30 miles with the range being affected mostly by large geographical barriers such as mountains, trees, or buildings. Usually, hand- held radios are used to communicate within a few miles or so, and if a greater simplex range is required, more powerful car- mounted or mobile radios are available with larger antennas. However, there is a way to extend the range of the hand- held's transmissions. Unlike FRS radios, hand-held ham radios can use "repeater" stations to relay their radio signals to greatly increase the distance of radio coverage. There are public repeaters located throughout the country, most of which are provided as a public service by local clubs or corporations. Ham operators may use these for communication in a responsible and courteous manner. Keep in mind that using a repeater greatly increases the number of people who can hear your transmission. There are several websites which publish local repeaters and the American Radio Relay League publishes a
directory of repeaters which is updated annually. Ham radios are not cost free, either. They require that you invest time to be licensed and money to buy a radio. However, they do provide flexibility and the ability for multiple users to communicate efficiently over fairly long distances. After your initial investment, there are no reoccurring fees or charges. If you become active in local clubs, they may have fees, but you also receive added benefits such as an "autopatch" or radio connection to the public phone network!

*The propagation at Disneyland is going to be better on the 70cm band. 70cm has an easier time penetrating buildings, so that is an advantage. In Southern California, most of the 70cm band is taken, but 446.0 and 446.5 are two common simplex frequencies. The disadvantage is that the Disneyland repeater runs on 2M. *There is no age minimum for earning a ham license. As long as you can pass the test, you can hold a license. However, keep in mind that just as there are studies to determine the long term effects of cell phone use, there are concerns about radiation exposure with the 2M band. *When you're using a ham radio or even an FRS radio, it's a good idea to wear an earpiece. This will allow you to monitor for messages from family and friends without disrupting fellow visitors.
