Installation / Setup
The source provides information on the installation of a receiver. It includes instructions for unpacking, which involves checking for any damage that may have occurred during transit and filing a claim with the carrier if necessary. The receiver should be placed in a location that allows for free air circulation through its ventilation holes and openings, avoiding areas near radiators or heating vents.
For antenna setup, the receiver can operate with either a single-wire antenna or a half-wave doublet antenna. The single-wire antenna is simple and can be set up by attaching one end of the supplied 15-foot antenna wire to the terminal marked “A1”, connecting a jumper link between terminals “A2” and “G”, and running the wire around the room. For better reception, especially in poor conditions, a longer outside antenna may be necessary.
For optimal performance, especially on shortwave and amateur bands, a half-wave doublet antenna is recommended. This antenna should be cut to the proper length based on the desired frequency and can be fed with either a balanced or unbalanced transmission line. The installation instructions detail how to connect these lines to the receiver’s terminals.
Additionally, the receiver is designed to operate on 108 to 125 volt, 50/60 cycle AC current, with provisions for operation from a DC power supply or batteries where AC power is unavailable.
