Debugging method of satellite pot: connect the receiver and tuner with closed circuit, the tuner is fixed on the feed plate of the pot, and the zero scale line of the tuner is approximately parallel to the ground. The receiver's audio and video are connected to the TV. Select an easy-to-receive channel or frequency point (such as gztv and China Education Television) to call up the signal quality. If the signal strength is above 60, the line is connected, otherwise there is something wrong with the line or interface. With the pot facing south, start to lower the elevation of the pot (the small pot is lower) and turn the pot to the east (or west). Then, slowly turn the pan to the west, slowly and always pay attention to the change of signal quality. {When the quality changes greatly (greater than 5), it should be adjusted slowly. When the quality can't be higher, fine-tune the tuner left and right, turn it a little, check the signal quality and adjust it to the maximum. Finally, fine-tune the distance between the tuner and the bottom of the pot (up and down or back and forth) to maximize the sound quality. } If the quality remains the same after turning to the west, raise the elevation of the pot a little and slowly turn the pot from west to east. If there are still no buns, raise the level of the pot a little, turn the pot from east to west, and repeat several times, raising it a little at a time. Until the signal quality changes. If there is an installed pot nearby as a reference, the range of turning the pot in the east-west direction is not so great (middle 6A is at 125 degrees, middle 6B is at 1 15 degrees, and middle 9 is at 92 degrees). On the map, look at how far east the pot is. If the diameter of the place is larger than the diameter of the satellite, the pot faces south to west. If the diameter of this place is smaller than the diameter of the satellite, then this pot is. In this case, the signal quality cannot be adjusted. Usually there is something wrong with the tuner or receiver (a few new machines may be broken). In addition, pay attention to whether the local oscillation frequency of the receiver is consistent with the frequency of the tuner.
