So what is mobile radio communications?
A mobile radio communication system usually consists of a base station and several mobile stations. The brief communication process is: When the caller speaks to the microphone on the base station, the base station will change the voice of the caller into an electric signal via the microphone and the converter and then transmit it through the transmitter; the receiver of the vehicle mobile station receives the power. After the signal, it is transformed into the original sound wave via the transducer and the speaker, so the listener hears the speaker's voice. Mobile radio communications use a wide range of wave lengths, including ultra-long wave, long wave, medium wave, short wave, ultra-short wave and microwave.

Nuts are Tight junction parts of mechanical equipment. Nuts and bolts of the same specification can only be connected together through the inner thread. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in nuts, M4 refers to the inner diameter of the nut is about 4mm, and 0.7 refers to the distance between two threads is 0.7mm); The same applies to American products, such as 1/4-20 nuts that can only be paired with 1/4-20 screws (1/4 refers to a nut with an inner diameter of approximately 0.25 inches, and 20 refers to 20 teeth per inch).
