  2. Modulated continuous wave - Wikipedia

    en.wikipedia.org/wiki/Modulated_continuous_wave

    v. t. e. Modulated continuous wave (MCW) is Morse code telegraphy transmitted using an audio tone to modulate a carrier wave . Continuous wave (CW), by contrast, does not use a subcarrier, so there is no emission at all between Morse code symbols. MCW can be generated by any AM or FM radio transmitter with audio input from an audio oscillator ...

    Add-on 455 kHz homemade BFO board. In a radio receiver, a beat frequency oscillator or BFO is a dedicated oscillator used to create an audio frequency signal from Morse code radiotelegraphy ( CW) transmissions to make them audible. The signal from the BFO is mixed with the received signal to create a heterodyne or beat frequency which is heard ...
