The Audio Oscillator generates a 650 hertz sine wave signal and can be used to generated an audio tone for the Night Sender Key, or it can be used to generate a side tone in a QRP or QRPp rig. The kit requires an external amplifier to drive a speaker or headphones as the output signal level is compatible with 'Line In' jacks on audio devices and TVs and VCRs..
