ABSTRACT:
In accordance with this invention, a radio repeater of the injection locked scillator type is provided with a feedback circuit for changing the free-running or rest frequency of the locked oscillator so that it follows the frequency deviations of the frequency modulation signal being repeated. This results in a higher gain for the repeater.
