HIGH FREQUENCY RADIOTELEGRAPH TRANSMITTER

Information

The model ET-8023-D1 high frequency radiotelegraph Transmitter 16 designed primarily for shipboard applications as listed below: 1 - For use in conjunction with a Radiomarine model 3U (intermediatefrequency) radio unit. In such installations, the model ET-8023-D1 uses the main motor generator and automatic starter of the model 3U radio unit* For example, on EC2-S-C1 Liberty vessels the addition of the ET-8023-D1 provides high frequency facilities. 2 - For use as an independent high frequency Transmitter, in which case the model ET-8023-D1 must be furnished with its own motor generator and automatic starter, these two units being mounted inside the high frequency frame. For application 1 (ET-8023-D1 in conjunction with model 30), a suitable length of 28 conductor lead and armored cable and lengths of copper tubing are furnished for interconnecting the equipment. See "Installation Instructions" in this book for details. The frame of the ET-8023-D1 is designed to mount a model AR-8506-B, or a model SLR-F, radio Receiver directly beneath the high frequency Transmitter. A small operating table, on which is mounted the telegraph key, is also provided with the ET-8023-D1. A motor generator transfer switch, mounted to the left of the radio Receiver, is provided in the frame so that the motor generator circuits may be quickly transferred for high frequency or intermediate frequency operation. An Antenna circuit transfer switch is mounted at the top of . the frame so that the high frequency Transmitter may be interconnected with the main and emergency Antenna circuits of the 3U equipment. The high frequency Transmitter used in this equipment is the same as the ET-8023 Transmitter employed in the model 4-U radio unit. In other words, the hinged section of the Transmitter itself is the same in ET-8023-D1 as in model 4.U. However, the ET-8023-D1 terminal blocks, external circuits, etc., in the lower section of the frame are different in ET-8023-D1 to provide interconnection with the Model 3U. The first section of this instruction book covers the operating instructions and general characteristics of the ET-3023-D1. The second section of this book covers installation instructions which should be carefully studied by installation personnel before interconnecting the ET—8023-D1 with the model 3U radio
