在印度尼西亚这样一个仍然坚持东方文化和宗教规范的国家，调频广播电台的内容被认为对社会的心理发展很重要。设立了一个监测广播内容的委员会。除其他外，其职责是管理对负面广播内容的投诉。目前，委员们必须访问调频广播演播室收集证据，这可能是非常昂贵的，因为演播室的位置可能远离委员会总部（>200公里）。我们提出了一个系统来远程监控调频广播电台的内容。通过使用这一系统，委员们不必访问这些站，而是从总部远程监测它们。我们只需要把系统放在我们想要监控的区域（一个区域可以是一个有几个调频电台的城市），并通过互联网发送广播内容。在我们以前的监控系统中，我们使用一个数字调频调谐器，可以用来监控（包括记录内容）一个站的时间。为了同时监测多个电台（记录一些电台），我们提出了一种基于SDR（软件定义无线电）的监测系统。结合OpenWebRX，我们可以同时监控一些FM广播电台。该系统可通过Web浏览器访问，用户可使用该浏览器监控多达4个站点。
In a country like Indonesia which still upholds eastern culture and religion norm, the content of FM broadcasting stations considered important for mentality development of the society. A committee to monitor broadcasting content has been established. Its responsibility, among others, is to manage complains on negative broadcasting content. Currently, the commissioners must visit the FM broadcasting studios to compile evidences, which is can be very costly since the location of the studios can be far (>200 km away) from the committee headquarter. We propose a system to remotely monitor the content of FM broadcasting stations. By using this system, commissioners do not have to visit the stations, instead they monitor them remotely from the headquarter. We just have to put the system in the area we want to monitor (an area can be a city wide with several FM stations) and send the broadcasting content via internet. In our previous monitoring system, we use one digital FM tuner that can be used to monitor (including recording the content) one station at a time. In order to monitor more than one station at the same time (recording some stations), we propose an SDR (Software Defined Radio)-based monitoring system. Combined with OpenWebRX, we can monitor some FM broadcasting stations at the same time. The system accessible via web browser which can be used by users to monitor up to 4 stations.
