1.带中继器区域通信系统的特点在无线电台之间相距200～500km的区域内可以实现短波无线电通信。在苏联西西伯利亚、东西伯利亚、远东地区及一些岛屿上,可靠、高效的区域短波无线电通信系统有相当明显的优点。在大多数很难到达的地区(例如多山、多河流、多沼泽的小居民点)很难建立和使用有线及微段接力通信线路,而且也不经济。 1. Features of the repeater area communication system Shortwave radio communication is possible in the area of ​​200 to 500 km between radios. Reliable and efficient regional shortwave radiocommunication systems have considerable advantages over the Western Siberian, Eastern Siberia, Far East and some islands of the Soviet Union. In most hard-to-reach areas (such as mountainous, multi-river, bog swarms) it is difficult and impossible to establish and use wired and microdata relay communications lines.
