我们给大家介绍一种简单、花费少的方式来利用近地卫星(LEO)进行VHF/UHF段FM通信。许多业余无线电爱好者尝试使用他们的手持电台和伸缩天线来与近地轨道卫星通信,但结果往往令人灰心。大家可能手边已经有了所有需要的设备,只不过不知道怎样得到更好的效果。在和卫星通信之前,除了必要的硬件设备,还需要一些必要的知识。这些知识在新版《ARRL卫星通信手册》或AMSAT的网站上都有详细的介绍。除
We introduce a simple and inexpensive way to utilize the LEO for VHF / UHF FM communications. Many amateur radio enthusiasts try to use their handsets and telescopic antennas to communicate with near-Earth orbit satellites, but the results are often discouraging. Everyone may already have all the necessary equipment on hand, but do not know how to get better results. Before communicating with satellites, in addition to the necessary hardware, some necessary knowledge is required. This knowledge is covered in detail in the new ARRL Satellite Communications Manual or AMSAT’s website. except
