Ham Radio Practical Guide Handbook

Over the past few years the line among conventional CB radio and 10 meter radio has become blurred. Phrases like ’10 meter CB radio’ and ‘export radio’ have irrevocably woven themselves into the vocabulary. Despite widespread use of both technologies a great deal of users have no idea what the real divergences are. A conventional CB operates on the 11 meter band at when it comes to 27mhz. This gives it 40 channels ranging from 26.965mhz on channel 1 to 27.405mhz on channel 40. The distinctive characteristic of CB is that access to these frequencies is unrestricted by the FCC and available to anyone. Thus the term ‘Citizens Band’. However altho access is unrestricted, use of these frequencies is another matter. Users are required to cohere to sure codes of conduct and severe hardware limitations. By FCC rule no CB transmitter may exceed 4 watts of transmitting power. A smart operator may use a high quality antenna to ‘get out’ further but increasing output by almost any other means is prohibited. By contrast 10 meter radio access is restricted but the allowable hardware is not as limited. 10 meter radios operate on frequencies ranging from 28mhz to 29.7mhz. To access 10 meter radio frequencies you are required to obtain an novice or ‘ham’ radio license from the FCC. Such licenses are comparatively easy to get and normally free of charge. Certain 10 meter radios likewise operate on FM radio frequencies which will require an even more modern license. The hardware involved in 10 meter radio may be rather impressive. Unlike CB communications the FCC considers the 10 meter band satisfactory for long range communication, a heap of radios offer over 100 times the transmitting power of a traditionalisti CB transmitter. So why has the line amid the two become blurred? Many CB operators dislike the severe limitations placed on CB transmission output. Manufacturers responding to this desire have formulated 10 meter radios that look and operate precisely like a popular CB. These new radios are without apparent effort altered to operate on CB radio frequencies which is in all probability what both the manufacturer and operator both had in mind when it was purchased. It is crucial to note that such modifications are versus FCC rules. The term ‘export radio’ is used to refer to these new CB radio style 10 meter radios. The catch is that these radios are supposed to be marketed for export use only. Many other countries do not have such severe limitations on transmitting power as does the United States. Although there is a huge amount of public desire to concede dandier transmitting power amongst CB radio users the FCC is very improbable to modify it is policy anytime soon. The FCC regards CB radio as a short range communicating device and does not want high powered transmissions interrupting local communications among other operators. This standpoint will closely surely preclude any modify in policy any time in the near future. By knowing the divergence amid 10 meter and CB radio, and how you intend to use your new equipment, determining which is the right model for you must be clear. |
