民用对讲机又称FRS(FamilyRadioService),中国信产部于2001年12月6日宣布开放民用对讲机市场,其开放的频段为409-410MHz,共分20个频道,称为“公众频道”。我们现在手中的小对讲机即属此类,由于大多数手台并没有预置这些频道,要实现互通必须手工调至相应频率。(400M波段中业余电台的使用频段是430MHz-440MHz,但很多手台都能调至409-410MHz)大多数民用对讲机还设有亚音静噪(CTCSS)功能,对讲机和手台互通时可以取消亚音静噪(将静噪频道调至0)

其他国家和地区的FRS开放频率和我国不同,有些朋友手中有出口到国外或从国外买来的民用对讲机,和在中国销售的对讲机就不能互通,但手台也可以调至相应频率。(严格地讲,在国内使用这些对讲机是违规的)

手置频的机机可参照以上频点设置,驴友们最好能把自己机机上的频道号和所对应的频率做一个小卡片过塑,就算给别人用也很方便啊......

发一个免执照对讲机频率对应表

现在国内,主要销售的免执照对讲机大多都是MOTOROLA的产品,型号有:T6200C、T5428、T5308等它们都使用400MHz频段公众对讲机工作频率请注意,如果是“T6200”,是美国的版本,频道是M国的FRS14个频道,462MHZ段的。如果是“T6200C”,重要的是那个“C”,就是中国CB频道,20个了。国内开放的民用频点CB,如T6200C:
