![VX410/420 SeriesOperating Manual8/10Vertex Standard Co., Ltd.ARTS (Auto Range Transpond System)This system is designed to inform you when you and another ARTS-equipped station arewithin communication range.During ARTS operation, your radio automatically transmits for about 1 second every 55seconds in an attempt to shake hands with the other station.If you have out of range for more than two minutes, your radio senses that no signal hasbeen receives, a ringing beeper will sound, and “IN RANGE” will appear on the LCD. If yousubsequently move back into range, as soon as the other station transmits, your beeper willsound and “OUT RANGE” will appear on the LCD.Understanding Radio WavesRadio waves travel from one point to another by several different means. The general termfor these methods of wave travel is “propagation”. You may know that “short-wave” signalscan be propagated over distances of several thousand miles by reflection off of the upperregions of the atmosphere.Your hand-held transceiver, on the other hand, operates on the so-called UHF (Ultra-High-Frequency) band. On this band, radio waves usually do not reflect off of the atmosphere.Instead, the radio waves behave almost as light; they travel in a straight line, and when meeta building or obstruction, they go no further in that direction.Therefore, it is important that you be as high and free from obstructions as possible to coverthe greatest distance when using your radio. If you operate from inside a car or building, anymetal around you can absorb much of the signal, both transmitted and received. Coveragemay therefore be very poor under those conditions. However, if you must operate fromindoors, moving next to a window will improve communications.In view of the factors just discussed, you can easily see the potential benefit of holding theradio up high near your mouth while transmitting. In this way the antenna is high and clear,and coverage is best.On final note regarding propagation is useful in improving coverage. Because radio wavesat UHF is similar to light waves, they do reflect, to varying degrees, off of hills, buildings, andthe like. In a crowded urban area, with many close buildings close together, many reflectionsmay occur, and interfere with one another, causing variations in signal strength at differentlocations.Therefore, if a signal is weak and you walk a few feet in any direction, reception maysuddenly become clear, because a particular reflection path may become dominant.Reflections are frequency useful, as they can allow for communications between twostations over a highly obstructed path.](https://usermanual.wiki/Yaesu-Musen/10504420.Revised-Operating-Manual/User-Guide-392736-Page-8.png)
