  • Abstract
    IN THE L-1 Carrier System, a pilot frequency of 2,064 kc is supplied at the transmitting terminal. Somewhat more than half the repeater stations are equipped with pilot regulators, which operate on their associated amplifiers to maintain a constant level of pilot at the amplifier outputs. By this means, variations in the loss of the coaxial cable (caused by temperature changes, for example) are compensated, and the over-all transmission maintained constant. At stations not having pilot regulators, manual gain controls are supplied; these are readjusted occasionally.
