Installation / Setup
The installation and setup of the Model SX-62/62U receiver involve several key considerations:
1. Unpacking: Carefully check all shipping instruction tags before removing them.
2. Location: The receiver should be placed on a table or shelf using its rubber feet. Avoid placing it near heat sources like radiators or in confined spaces.
3. Power Source: The receiver can operate from an AC source (105 to 125 volts, 50/60 cycle) or a DC source. For AC operation, ensure the power source matches the specified voltage and frequency. A universal model is available for different voltages and cycles. For DC operation, a 6-volt DC motor source and a 270-volt DC supply are required. The receiver will not operate from AC unless the jumper plug is in its BATTERY POWER receptacle.
4. Speaker Connection: There are three screw-type terminals on the rear chassis for speaker connection, supporting 500 and 5000 ohms output impedances.
5. Antenna: A three-terminal strip is provided for antenna connections. For a single wire antenna, connect a jumper between “A2” and “GND” and the antenna to “Al”. The antenna should be high and free of obstructions. A ground wire may be connected to “GND” if needed. A doublet antenna is recommended for high-frequency bands.
Operation
The Model SX-62/62U receiver is a high fidelity superheterodyne receiver that covers broadcasting services between 540 kilocycles (KC) and 109 megacycles (MC). It can receive both FM and AM broadcasts. The receiver features a built-in 500 ke crystal controlled calibrating oscillator for accurate dial calibration, allowing users to log prominent shortwave stations and active communication channels directly on the dial. The receiver’s selectivity is adjustable for different types of broadcasts, and it includes an automatic noise limiter to reduce background noise. A RECEIVE-STANDBY switch allows for quick disabling of the receiver without waiting for tube heaters to warm up. The receiver can operate from a 105-125 volt 60 cycle AC source or external batteries where AC current is unavailable. Installation involves checking shipping tags, selecting a suitable location, and connecting to the appropriate power source. The receiver can be powered by AC or DC sources, with specific requirements for each. Speaker connections are available for 500 and 5000 ohm outputs, and antenna connections accommodate both single wire and doublet antennas.
