|Hallicrafters Co. HT-44 Transmitter|
The Hallicrafters Model HT-44 is a seventeen- tube Transmitter/Exciter capable of SSB (Single Sideband with suppressed carrier , AM (DSB), and CW transmission in the 80, 40 20, 15, and 1O meter amateur bands. This unit can represent the complete transmitting complement of a station. The only requirements for immediate ’’on-the-air” operation are a PS-150-120 Power Supply, a 50-ohm terminated antenna system, a key or microphone, and an AC power source. The unit may be utilized as a complete transmitter, or as an exciter for driving a linear amplifier Such as an HT-45, HT-33B, HT-41, or others. If other linear amplifiers are used, they should be capable of supplying a 50-ohm termination for the HT-44. When used in conjunction with an SX-117 receiver , slave (transceive) operation or independent operation is selectable by a panel switch. An outstanding feature of the HT-44 is the amplified Automatic Audio Level Control (AALC). The AALC circuitry virtually eliminates splatter commonly caused by excessive audio gam and its; resultant "flat-topping." This is accomplished by providing up to 12 DR of compression at the point where flat-topping would normally occur> assuring maximum talk power while maintaining a clean, sharp signal.
