Analog Communication System

This training system is designed to help learners understand the working principles of a walkie-talkie operating in the 144 MHz VHF band.

The system demonstrates the internal operation of a walkie-talkie through clearly defined functional blocks, allowing learners to study both transmission and reception processes.

Main Functional Blocks :

The circuit is divided into the following key sections:

• Receiver block
• Transmitter block
• Audio amplifier block
• Microphone amplifier block

• Block diagrams are clearly displayed on the module panel
• Provides a visual and practical understanding of system operation
• Helps learners grasp the signal flow and interaction between different components
