With the development of the economy, microelectronic technology, radio communication technology and the automatic theory are developed rapidly, the compound frequency technology has been in a new state. It's application is becoming more and more widely. But the radio as an important pastime tools , it also has developed quickly with the improving requirement of the people .It's radio technology has developed from tradition capacitance or inductance to digital .
The article is based on the now-being general radio module, using AT89S52 microcontroller to control the radio, by 1602 for liquid crystal display modules, with TEA5767 the high sensitivity, low voltage and low power consumption of all the advantages of integrated chips for the radio module. the reliability is improved and the feeling of comfort is better through the reasonable design, so the function of radio is more powerful compared with tradition one .
