为了适应高山调频发射台自动化工作的要求,我厂设计试制了TF3型10千瓦自动化调频发射机以及SZ1型广播发射台专用数字钟。数字钟是控制整个机房全部发射机的设备,高山调频发射台的最大可能容量预计不超过七套发射机(其中包括电视发射机),数字钟就是按这个容量设计的。发射机与数字钟互相配合,自成体系,数字钟按预置的时间送出开、关机
In order to meet the requirements of Alpine FM Transmitter Automation, our factory designed and trial-produced TF3 10 kW FM Transmitter and SZ1 Broadcast Transmitter Digital Clock. The digital clock is a device that controls all transmitters throughout the room. The maximum possible capacity of the alpine FM transmitters is not expected to exceed seven transmitters, including the television transmitter, which is designed for this capacity. Transmitter and digital clock complement each other, self-contained system, the digital clock according to the preset time to send open, shut down
