1. A method of controlling system stability of an on-frequency repeater, the method comprising steps of:
- generating a signature signal associated with the repeater;
inserting the signature signal into a first RF signal transmitted by the repeater;
detecting a correlation between the signature signal and a second RF signal received by the repeater; and
controlling an effective radiated power (EP) of the first RF signal transmitted by the repeater, based on the detected correlation.

Abstract
A system operates to adaptively control the stability of an on-frequency repeater. A unique signature is imposed on RF signals transmitted by the repeater, and RF signals received by the repeater analyzed to detect signal components corresponding to the signature. The signature and the detected signal components are correlated by a micro-controller, which operates in accordance with an Adaptive Control Algorithm to adjust the ERP of RF signals transmitted by the repeater to limit signal leakage and thereby control the stability of the repeater.
