Installation / Setup
The installation/setup highlights for the Hallicrafters Model S-82 FM receiver include:
1. Unpacking: Check all shipping labels and tags for instructions before removing or destroying them.
2. Location: The receiver is equipped with rubber feet for table top or shelf mounting. Avoid placing it near excessively warm locations like radiators or hot air outlets. Ensure ventilation openings on the top and back of the cabinet are not covered.
3. Power Source: The receiver operates on 50/60 cycle 105-125 volt AC or 105-125 volt DC, with a power consumption of 30 watts. If unsure about the power supply, contact the power company before plugging in the receiver. For DC operation, reverse the power plug at the wall outlet if the receiver does not operate after a one-minute warm-up period. Mobile operation is possible with a 6 volt DC to 110 volt AC power inverter.
4. Antenna Installation: Terminals marked A and G on the back of the receiver are for antenna and ground connections. A six-foot antenna wire is included for indoor use, providing reception over a distance of approximately 7 to 10 miles. For greater distances, an outside antenna such as a vertical whip or doublet may be required. The doublet antenna can be constructed from a 300 ohm twin-lead TV transmission line, and should be mounted vertically for optimal signal pickup. The lead-in should run at right angles to the antenna for at least 12 inches and connect to terminals A and G on the receiver.
