The radio is a small radio. It is mainly used for receiving radio programs and listening to entertainment and information programs sent by radio transmitters (usually radio stations). It has a radio receiver different from the military. This is not broadcasting. With the development of science and technology in the later period, great changes have taken place in broadcasting production technology, and digital broadcasting has also come out. Next, I will introduce digital radio to you.

Digital radio stations mainly work through digital transmission technology, and listen to digital radio stations through their signals. The sound quality of digital transmission technology in digital broadcasting is impressive, and it also has absolute high-definition texture, and its sound quality will not be affected by any external signals. Digital radio and traditional analog radio have absolute advantages in sound quality. Its digital signal will not be affected by external signals, and the listening station is no longer limited to the frequency range of analog signals.

Maintenance method of digital radio:

1, TV, fluorescent lamp, SCR dimming desk lamp, computer, automobile engine, motor and other electrical appliances have strong interference to the medium wave and short wave of the radio. When using the radio, please keep a certain distance from the above appliances to avoid interference.

2. Reinforced concrete buildings and high-rise buildings in listening places have a certain masking effect on broadcast signals.

Use close to the window can improve the reception effect. 3. The signal sent by the calling station near the listening place will seriously interfere with the listening of short-wave radio programs. We can shorten the length of the rod antenna, adjust the angle, or change different listening positions to improve the receiving effect.

4. Adding a simple external antenna to the radio can improve the short-wave receiving ability of the radio. That is, the length of 3-4 meters is used, one end is clamped on the rod antenna, and the other end is hung outside the window.

5. Do not use an external power supply higher than the rated voltage of this machine to avoid damaging the machine.
