Section V. RADIO SUPPRESSION
96.
Definition of Suppression
Radio noise suppression is the elimination or minimizing of engine electrical disturbances within the equipment which
interfere with the radio reception and disclose the location of the road roller and its associated equipment to sensitive
electrical detectors.
97.
Source of Interference
Spark plugs, high tension leads from the magneto to the spark plugs, magneto breaker points, magnetic switches,
voltage regulators, electrically operated gages and meters, generators, and poor electrical joints between the adjacent
parts on the road roller frame are sources of electrical interference.
98.
Methods Used to Suppress Interference
The radio interference suppression equipment consists of capacitors, shielding and bonding cables, and internal
toothed lockwashers, placed at various points in the electrical circuit of the engine and the road roller. The capacitors
bypass radio frequencies to ground and prevent them from being radiated. The shielding and bonding cables and internal
toothed lockwashers prevent radio frequency radiation
