The difference between simple concept of amateur radio / professional radio / radio
Radio is not to say! to listen to other launch pad out signal, usually Radio FM (FB) / amplitude modulation (AM) in two parts. two different modulation methods, corresponding to the radio . these forms of modulation! we used to support the 430MHz segment FM radio! air traffic control between 110MHz to 130MHz frequency, the AM modulation mode! Then, some simple difference buy two way radios between "amateur radio professional radio
A layer of meaning that amateur radio support amateur band radio - support (included) 430MHz ~ 440MHz band radio! professional radio is another layer of meaning to support some other specific band radio amateur radio functions focus on "play" adjustments, including the various relevant parameters to adjust the transmit power signal frequency / / Search storing a plurality of different frequency / frequency manually save changes / adjust the squelch value / signal intensity tables, professional radio pay more cheap two way radios attention to stability, so the complexity of the operation is relatively low. and durability / stability of the transmission power of the battery performance requirements higher!
Need to use a computer and special software and connection to adjust contrast, professional radio is usually not at liberty to adjust the transmit power / frequency search function / can store a small amount of frequency and can only display channel number can not display the value of the frequency / stored in each channel frequency and discount two-way radios related functions / usually there is no signal strength meter and professional radio might also designed to increase security measures such as FM, or support the function of the cluster (I know not many ) you want to transport JC armed JC what they take a stand, to know which is the switching volume, according to which words! screwed to a few channels squadron! a few channels total station would be finished, if you take a fancy amateur radio to JC, Paul! he will not use,
