ET 'A' School Curriculum Outline

Section Duration Title
Unit 1: Fundamentals 20 Days Unit topics include direct and alternating current, beginner electronics vocabulary, electrical safety fundamentals including CPR certification, test equipment usage, simple circuit analysis, power supplies, and basic troubleshooting techniques.
Unit 2: Advanced Circuits 13 Days Topics include semiconductors, transistors, multistage amplifiers and regulated power supplies.  Various digital circuits including numbering systems, logic circuits, flip-flops, multivibrators, and shift registers are covered.
Unit 3: Receivers 21 Days Teaches basic principles of communications, modulation, mixers, IF filters, amplifiers, demodulation and audio amplifier circuits. RF Principles also teaches antenna transmission concepts, and antenna maintenance. Students utilize a NIDA Lab Model HF Receiver and a Harris Corp R-2368 to practice signal tracing and troubleshooting.
Unit 4: RT-9000 24 Days Students learn the primary building blocks of a transceiver and apply this knowledge to the RT-9000 HF transceiver system. Students will perform corrective and preventive maintenance to the receiver, transmit, synthesizer, and the power supply section of the transceiver. Students will also be introduced to modulate and demodulate devices (MODEMS) and remote operations of the RT-9000.
Unit 5: Systems/Crypto 13 Days This unit teaches operation and limited maintenance on cryptographic equipment including KG-84C, ANDVT, KY/HYX-58, and AN/CYZ-10 DTD, down to card level. Students are taught how to set up equipment in an HF voice or data system in a simulated communications suite, along with troubleshooting and isolating faulty equipment within the system.  All ET “A” graduates are assigned the COMSEC competency and receive official authorization to work on this equipment upon graduation.
Unit 6: SINS 20 Days This unit introduces RADAR, GPS, Depth Sounders, and NMEA fundamentals, using the Scalable Integrated Navigational System (SINS) installed on Coast Guard small boats as the training platform. In order to become familiar with the concepts, students learn and demonstrate proper operation, preventive maintenance, and corrective maintenance of the SINS.
Unit 7: VHF 13 Days Concepts introduced in this unit include the operation and maintenance of direction finders and secure VHF transceivers including antenna and coaxial cable system troubleshooting. Current Coast Guard electronics logistics systems are covered to include ALMIS, CMPlus, and FEDLOG.  Students are also trained in basic tower climbing.
Unit 8: Soldering 10 Days Basic soldering workbench techniques are covered.  All common coaxial and multi-conductor cable connectors are studied. There is extensive lab performance testing of soldering techniques and connector building.


This course provides technical instruction on basic electronics, digital circuit theory and communication fundamentals, using advanced computer trainers and the communications equipment used throughout the Coast Guard fleet. This course encompasses the use of test equipment, technical publications and troubleshooting methods used for corrective maintenance to the lowest repairable level. Upon graduation our students will have the knowledge and skills necessary for advanced electronics classes, on-the-job training programs, and the performance of basic technical tasks.
