Here are some criteria for setting up an emergency communications system 1 It should be easy to operate. There are at least five communications systems that more or less meet these criteria. Some have big drawbacks, others minor ones. In making your choice, you should examine your own needs and match them with the appropriate system. Cell Phones. Nextel. CB Radio. In the late 5. FCC took a set of frequencies from the Amateur Radio service and designated it as the Citizens Band. The rules were simple a rubber stamp license, low power, ease of operation and channelized tuning. But the service was a relative sleeper til the 7. Smokey and the Bandit and popular tunes like Convoy, with their rachet jawin, truck drivin cowboys, captured the American imagination. That sent a stampede of otherwise respectable Americans onto the airwaves and the Interstate and overwhelmed the sluggish FCC which promptly abandoned the band to the mayhem that ensued. The Commissions only response to the millions of yahoos yelling at each other over CB was to expand the band to 4. If you havent used a CB in the last 2. The units themselves are virtually unchanged which leads one to wonder if theyre still selling off excess inventory from the initial craze. Prices for complete systems are cheap. In many areas, the CB channels are relatively quiet. Advantages of using CB radios for emergency communications are considerable. Aside from the low price tag, lack of licensing and fees, they are operated on your cars 1. Their range, depending on antenna type and placement, can be anywhere from one to fifteen miles. Disadvantages of CBs are few, but persistent. Antennas tend to be large 4 to 8 on vehicles and larger for base or home stations. While much smaller antennas are sold, their effective range is drastically reduced. Transmissions tend to leak into all kinds of other electronic devices. In the home, CBers will often be heard on TV speakers, corded telephones, electronic keyboard speakers, etc. This was an aspect the FCC came to regret as the Commission was faced with hundreds of thousands of complaints from frustrated neighbors. Another problem is that sometimes, during favorable atmospheric propagation, range can be as great as several thousand miles. Thousands of people all hitting their mike buttons at the same time sets up an unearthly squeal and nobody gets through. Prices for CB radios range from US5. AMSingle Side Band SSB capabilities. I recommend units with built in Weather Radio receivers. Antennas are sold separately and range from 2. MHz Personal Communicators. After the CB fiasco and before the Family Radio Service was established, manufacturers took advantage of FCC rules regarding transmissions in the 4. MHz band. They built small, lightweight, self contained, low power systems which featured a single headset with boom mike attached to the transmittercontroller which could be clipped onto the users belt or pants pocket. Usually single channel operation only, some models are sold with as many as five frequency channels. All feature PTT push to talk mikes as well as VOX voice operated transmitters. The VOX feature makes them ideal hands free systems for cyclists, joggers or motorcyclists. Without speakers, the audio is heard only through the earphone. Early cordless phones, baby monitors and a few other devices share this band. The advantage of this system is the extremely low power drain. Most sets are powered by only 2 or 3 AA batteries and can be in service for months. Their size makes them perfect for traveling lightand taking up very little space. The big disadvantage is limited range. Expect under a quarter mile coverage with these systems. This can be seen as an advantage when you dont want to battle hundreds of other people on your frequency. Prices for 4. 9MHz Personal Communicators range from 3. Family Radio Service. Once again, the FCC has tried to give the average citizen a chance to use the airwaves with a new scheme they call the Family Radio Service FRS. Here the Commission sought to re dress the problems of the first citizens band. They assigned the band frequencies in the UHF region around 4. 3 Versiones Judas Pdf more. MHz which limits the propagation induced range. They also limited the output to one half watt and transmissions use Frequency Modulation FM. All are small, battery powered handi talkies which can easily fit into a pocket. The Commission has again chosen channelized operation and this time has allowed 1. Advantages of FRS units are that they are very compact typically 4 h x 2. The UHF frequency means they have very short antennas typically only a few inches. Some units also have such useful features as optional headsetboom mikes for VOX operation, audible low battery alert and transmit LED. Some units feature 3. Other notable features include a programmable scan feature and automatic power off shuts down if not used after a certain period of time. The main disadvantage of these units is the relatively short range. While manufacturers claim up to two miles, dont expect more than a mile. Expect to pay 5. FRS models, 9. General Mobile Radio Service. The General Mobile Radio Service GMRS is like the FRS in that it operates in the 4. MHz region, uses small handi talkies and is intended to be used by individuals to communicate with immediate family members. The big differences are that GMRS requires an FCC license with a fee and users must be 1. In addition, the output of these units is considerably greater 1 to 5 watts, allowing a range of coverage from 5 to 2. There are 2. 3 GMRS channels used on an unassigned basis and dependent on the cooperation of all users. The channels are split up for base, mobile relay and fixed station or mobile station use. Each license is assigned one or two of eight possible channels or pairs as requested by the license applicants. In order to avoid interference or conflicts in use, the FCC recommends monitoring existing frequencies in your area before making your application and requesting your channels. The advantage of the GMRS is that this is the most useful of the previously listed services, but brings with it disadvantages of government oversight and stringent frequency assignment.
