Morse code is a code of signals used in military communications in the past. But today, it is also common among surfers radio The percussion Morse code as a standard in radio communications. This circuit is a demonstration of tapping Morse code basics.
Enter the power supply circuit is on, press the S1 Charset circuit IC1 is run by the generator frequency Per cycle, which is a sensitive multi-Stable Brett Foster is R1, C2 and VR1 determines the frequency of the output pins 3 go to the VR1 speakers for optimized sound to very sharp pointed at.
