Sine-Wave Oscillator

    This simple AF oscillator is quite stable and if polystyrene capacitors are used can be accurate enough for a repeater access tone-burst generator. Two such oscillators could could be used to to generate the two-tone signal required to test SSB transmitters.The 10n and 10K resistors govern the frequency of the oscillator. The values shown place the frequency of oscillation somewhere in the center of the communications AF spectrum
