Installation / Setup
The installation/setup highlights for the Model SX-62B radio receiver include the following:
1. Unpacking: Carefully check all shipping instruction tags before removing them.
2. Location: The receiver is equipped with rubber feet for tabletop or shelf mounting. It should be placed away from excessively warm locations such as near radiators, hot air registers, or confined dead air spaces like recessed installations.
3. Power Source: The receiver operates from a 105 to 125 volt, 50/60 cycle AC outlet with a power consumption of approximately 120 watts. If unsure about the voltage and frequency rating of your utility service, consult a local power company representative. A special model is available for operation from 115 V./130 V./150 V./220 V./250 V. 25/100 cycle AC sources. A selector switch on the power transformer allows operation on any of the specified line voltages. It is important to check and set the selector switch on the power transformer before connecting the receiver to the power source.
4. Speaker Connection: Three screw-type terminals on the rear chassis apron are provided for speaker connection, with output impedances of 500 and 5000 ohms. Suitable speaker units that operate with these impedances can be used with the receiver. The Hallicrafters Model PM-23 speaker connects to the 5000-ohm terminals marked “COM/5000”.
Operation
The Model SX-62B radio receiver operates as a high fidelity superheterodyne receiver covering broadcasting services between 540 kilocycles (KC) and 109 megacycles (MC), capable of receiving both FM and AM broadcasts. It features a built-in 500 ke crystal controlled calibrating oscillator for accurate dial calibration, adjustable selectivity for different broadcast types, and a high fidelity tone compensated audio system with four tone ranges. An automatic noise limiter reduces background noise, and a RECEIVE-STANDBY switch allows for short standby periods without waiting for tube heaters. The receiver operates from a 105-125 volt 60 cycle AC source, with an option for external battery operation. A special model can operate from 25 to 100 cycle AC sources at voltages from 105-250 volts. Proper adjustment of sensitivity, tuning, and tone controls, as well as antenna selection, is important for optimal performance.
