Abstract: This relates to level regulation in a carrier frequency system with a plurality of repeaters in tandem. More particularly, the level regulator at the repeaters suppress overshoot (excessive regulation) by one or more regulators. The level regulator is disposed in each repeater of a pilot-controlled repeater chain. Suppression of overshoot is obtained by a gradient discriminator in each repeater which detects the rate of change of the pilot level deviation from a nominal level. If the rate of change exceeds a predetermined value, the level regulator is blocked.
