CW Practice oscillator

Posted on Feb 5, 2014

A circuit diagram that can be used for the generation of CW Morse code is shown here. This circuit can be very useful those who would like practice Ham Radio. The circuit is nothing but an astable multivibrator based on NE 555. The frequency of oscillations of the circuit depends on the components R1, R2 & C1. The circuit can be powered from a 9V PP3 b
