Controls & Indicators
The front-panel controls and indicators for the Hallicrafters Model 8-80, “Defender,” include:
1. OFF-VOLUME Control: This knob is used to turn the receiver on and off and to adjust the volume. Turning it clockwise turns the receiver on and increases the volume, while turning it counterclockwise decreases the volume and turns the receiver off when a click is heard.
2. TUNING CONTROL: This knob is used to tune in the desired station. It is turned slowly until the dial pointer indicates the station frequency.
3. SHORTWAVE-BROADCAST SWITCH: This control knob is used to select between standard broadcast reception and shortwave reception. It is set to “BROADCAST” for standard broadcast reception or to “SHORTWAVE” for shortwave reception.
Installation / Setup
The setup for the Hallicrafters Model 8-80 “Defender” radio involves several key steps:
1. Battery Installation: The radio operates on a combination 90 and 1.5-volt battery pack. Specific compatible battery packs are listed, and the battery should be placed in the compartment at the rear of the cabinet. The battery saver switch should be set to “NEW” when a new battery is installed, and to “USED” when the battery life is nearing its end.
2. Antenna Installation: Two leads are provided for antenna and ground connections. A single wire antenna should be 30 to 60 feet long and connected to the green lead, with a good ground connection required. A doublet antenna with a 300-ohm ribbon type transmission line is recommended for shortwave reception.
3. Antenna Construction: For a single wire antenna, it should be erected high and free from objects, with a lightning arrester used at the lead-in point. The doublet antenna should be 19.5 feet long on each side, with no ground connection required.
4. Tuning Dial: The standard broadcast band is calibrated in kilocycles, and the shortwave band in megacycles.
5. Reception: The SHORTWAVE-BROADCAST control knob should be set accordingly, and the VOLUME control adjusted for desired sound levels.
