1. Technician License Course Chapter 2 Lesson Plan Module 3 – Radio Equipment Basics

2. The Basic Radio Station

3. Basic Station Organization Station Equipment –Receiver –Transmitter –Antenna –Power Supply Accessory Station Equipment Repeaters

4. Special Stations You Will Use (Repeaters) Repeaters are automated stations located at high places that receive and then retransmit your signal – simultaneously. –Dramatically improves range. The basic components of a repeater are the same as your station: receiver, transmitter, antenna and power supply.

5. Repeaters But, repeaters are transmitting and receiving at the same time using the same antenna. This requires a very high quality and specialized filter to prevent the transmitted signal from overpowering the receiver. This specialized filter is called a duplexer.
