1. A method of detecting oscillation in an on-frequency repeater having an RF signal path coupled between an input antenna and an output antenna, the method comprising steps of:

  • detecting a first RF signal power level within the RF signal path during an un-muted period in which transmission of an output RF signal through the output antenna is enabled;

    detecting a second RF signal power level within the RF signal path during a mute period in which transmission of an RF signal through the output antenna is disabled; and

    comparing the first and second detected RF signal power levels.
