CONTINENTAL ELECTRONICS 416 E

GENERAL DESCRIPTION


AM Broadcast Transmitter Type 416 E 10 kW SW

photo Continental Electronics 416 E Continental's Type 416E short wave broadcast transmitter is a manually tuned, high quality unit designed for A3 operation over the frequency range.

All operating controls are located on the front of the transmitter for simplicity of operation. Front panel meters monitor all important electrical parameters.

The transmitter consists of two cabinets: one cabinet contains the power supply and control circuits, the other cabinet houses the power amplifier. The exciter is housed in a separate rack mounted chassis.

High-gain power tetrodes are used in the linear amplifier: one 4CX350A is used for the driver stage; one 4CX35000C tetrode makes up the power amplifier.

Superior harmonic attenuation and impedance matching capability is achieved by using a "Pi-L" output network for the power amplifier. Transmitter door interlocks and door-operated high voltage switches protect personnel and equipment.

The transmitter is self-contained and occupies 1.9 sq. meters of floor space. The transmitter operates efficiently within an environment of -10 to 45 C; up to 95% relative humidity; at altitudes up to 1524 meters above sea level.
