时代的推进,促进了社会各个行业领域的迅速发展,尤其是我国的广播事业在近些年得到了进一步的发展,在不同地区的电台当中,新的调频立体声发射机被广泛的运用,高频率放大器是由大功率场效应管所组成,通过对先进技术的运用,体积也比较小等的优势,帮助相关的技术维护人员能够在短时间内发现设备的问题,并且针对性的进行有效的处理,本文针对调频发射系统的故障检修和维护心得进行了论述,希望有一定的参考价值。 The advancing of the times has promoted the rapid development of all sectors of society. In particular, the broadcasting industry in our country has been further developed in recent years. Among the radio stations in different regions, the new FM stereo transmitters are widely used. The high frequency Amplifier is composed of high-power FET, through the use of advanced technology, the volume is relatively small and other advantages to help the relevant technical maintenance personnel to find equipment problems in a short period of time, and targeted for effective treatment In this paper, FM transmission system troubleshooting and maintenance experience are discussed, I hope there is a certain reference value.
