Morse Code Decoder Circuit
I have been getting a lot of emails about this project. Most of them are because of the bad source code listing at the end of the author`s n...
Electronic keyer
This circuit automatically produces Morse code dots and dashes set by time constants involving Cl and C2. Rl sets dot/dash ratio and R2 sets...
Morse Code astable Oscillator
Astable or free-running multivibrators have been used in home-built amateur radio equipment for many years. The basic circuit is a two stage...
Morse Code with touch button (555)
This simple CPO is for those who want to practice Morse Code in a different way, ie with out the morse key. It can be also used as a touch o...
Morse Code Alarm Clock
(Almost) Trivial application of an AT90S2313 or ATtiny2313 in an alarm clock to change the alarm from "BEEP BEEP BEEP BEEP BEEP BEEP BEEP BE...
Morse Code Beacon Keyer
This circuit stores a single morse code message as bits in an EPROM chip, the message is sent to a relay which can key a CW transmitter. The...
CW Sidetone Generator
This circuit is about as good as it gets for generating morse code tones. It may be used as a code practice oscillator, a tone generator for...
