How a Basic CW Transmitter Works

This lesson explains the simple building blocks of a Morse code transmitter and why each part is necessary for a stable signal. You will learn how electricity flows through the system and how the operator controls the transmission.

This lesson is part of SignalPrep Pro. The subsection's 6 exam questions are free to practise: practise B-003-004.
