文章介绍了８０３１单片微机控制系统在超短波电台中的应用。该超短波电台为半双工工作方式；工作频段为１４６—１５６ＭＨｚ，频率能以１０ｋＨｚ的间隔灵活变化。收发信机的频率源由锁相频率合成器提供。收发频率合成器的频率编码由单片微机控制输入。控制系统还具有键盘／显示接口，能够接收各种人工指令，显示及输出相应的结果；它具有预置频率、检错、复位以及断电保护等功能，并且通过收发标志控制收发频率合成器
The paper introduces the application of 8031 single chip computer control system in UHF radio station. The UHF radio is a half duplex mode of operation; the operating frequency band is 146-156 MHz and the frequency can be flexibly changed at 10 kHz intervals. The frequency source of the transceiver is provided by the phase-locked frequency synthesizer. Transceiver frequency synthesizer frequency coding by a single microcomputer control input. The control system also has a keyboard / display interface, can receive a variety of artificial instructions, display and output the corresponding results; it has a preset frequency, error detection, reset and power protection and other functions, and through the send and receive control send and receive frequency synthesizer
