This Code Practice Oscillator Kit is a very popular and practical device used in Ham Radio for practicing your Morse Code. It is designed as a One-Transistor, Twin-Tee, Audio Phase-Shift, Sinewave Oscillator with an Audio Amplifier on the output.
The kit produces a very clean sinewave of either 700Hz or 1000Hz. You will get the parts to build either frequency. Note: 700Hz is extremely popular and very pleasing to the human ear.
The input is a 1/4" phono jack while the Speaker output & 9v Power input each use a 2-pin screw terminal. You can mount the PCB via the 1/4" phono jack directly on a panel, such as a Speaker Box.
Plug your existing key or "bug" into the 1/4" phono jack or wire it in directly and leave the phono jack out, your choice. You can even put in a momentary switch of your choice. The input requires a switch to ground to produce a tone.
The PCB is 1.0" x 2.0" and is very easy to build.
This kit is offered with a "Built & Tested" option for those that do not want to build the kit themselves.
This kit does not include a battery nor a speaker.
