The transmitter is either sending carrier or not sending carrier.3. The reason you hear beeps at the receiver is due to how the receiver works. That's what some people erroneously refer to as "CW". This is usually done by keying the transmitter on and off.
The SpikenzieLabs Telegraph Decoder Kit Transmitting Morse code isn't that hard.

All the parts used on this project are common and can be ordered from any electronics website or Amazon. This is a simple and relatively cheap project.
555 Morse Code Practice Oscillator For the first electronics project on the blog, I wanted to start with the 555 Morse Code Practice Oscillator.Another one, the frequency range below and include IC1a IC1b. This circuit provides a higher frequency, IC1c, and includes IC1d.
We designed it using CMOS integrated circuit, 4011 (CMOS Quad 2-Input NAND Gate). Excellent for learning and teaching Morse code, this code practice oscillator - ideal solution to practice sending the code and improve your speed - is a light-weight portable unit powered by one AA cell (1.5V/1.2V) and is based on the well known 'Joule-Thief' concept.This Resonance generator (oscillating sound generator) circuit. These wires are not polarized and can go directly into a Morse .Little circuit of a Morse Code Oscillator is presented here.
Strip both ends of two pieces of wire, and screw then into the screw terminal. A stri p of heavy copper or a piece of copper -clad circuit board will serve as a key.30 de set. The code practice oscillator would be great for anyone looking for science fair -like ideas. Need to get a ham license but have to wait a year to get back to States.Project teachers, we've found that kids still really love Morse code and this little project seemed like a natural to cultivate interest. No end to the stuff you can build and it is fascinating. Have learned Morse Code but listening is a skill that is going to take a while. Also built an antenna tuner which greatly increases receptivity.
