Morse Code Oscillator and Amplifier.
Practice your Morse code with a true to life (Morse life) oscillator. Suitable for straight (non-iambic) keys only.
Utilizing a Twin T oscillator, you get a note at around 950 - 1000 Hz, very similar to on air or side-tone Morse.
NE 555 based (and similar) units produce a square wave output that is not true to life Morse as heard on air.
Our high quality printed circuit board includes the oscillator and an amplifier, on board power jack, on/off switch, speaker/headset jack and morse key screw terminals.
Hook up to a 9 volt battery (or small up to 12 Volt dc supply) to start the your code session.
Amplifier allows the oscillator to be used to feed an 8 ohm speaker and use in classroom settings or by use of the volume control and earbuds practice quietly on your own.
Fully assembled and tested.
Please Note: Current batch of this item comes with a Green PCB!
