北京铁路分局丰台电务段自1951年开始安装试验机车无线调度电话。先后曾用过苏联产品P-1,P-3型电台,这种产品十分笨重,机械电气性能很差。后来随着我国无线电工业的发展,仿制了苏联的一些产品,虽然体重减轻了,但机械电气性能还是较差。由于受到刘少奇修正主义办企业路线“洋奴哲学”、“爬行主义”的干扰,结果全部下马。
Beijing Railway Branch Fengtai Electrical Services Section since 1951 to install the test locomotive wireless dispatching telephone. Has used the Soviet Union products P-1, P-3 radio, this product is very heavy, mechanical and electrical performance is poor. Later, with the development of China’s radio industry, some of the products of the Soviet Union were imitated. Although the weight was reduced, the mechanical and electrical performance was still rather poor. Due to the interference of Liu Shaoqi’s revisionist enterprise line “Western slave philosophy” and “repressionism”, the result was totally dismissed.
