Rare Sony world radio Digital World Receiver Portable, microprocessor-controlled, frequency-synthesized general-range receiver with push-button tuning and storage for up to ten favorite stations. It features a 12/24-hour digital clock and timer and is powered by six AA batteries (two for the computer and clock, and four for the radio). A 6-volt adapter is used for power. An internal ferrite antenna is used on medium and long wave bands. The extendable antenna on the top is used for FM and short wave. An external wire antenna can be connected using a 3.5 mm jack plug, which is also used for earphones. The ferrule can be connected to ground, and the tip should be connected to the antenna wire. When this connection is used, the internal ferrite antenna is disconnected, and medium and long wave frequencies are attenuated. The frequency range is 153 kHz to 26.100 MHz continuous, and FM from 87.6 to 108 MHz. Introduced in 1983. The Sony ICF-7600DS has a continuous frequency range of 153 kHz to 29.995 MHz and FM from 76 to 108 MHz. This model has a BFO and can be used to listen to single-sideband transmissions. This receiver was introduced in 1987. On the left side are a carrying strap, a sensitivity switch, a stereo earphone jack (18Ω), a recording device jack, and the power supply jack. On the right side are a fine tuning knob (used with the adjacent knob, which switches to SSB reception), a tone switch, and the volume control. The main power switch is located on the top. The time can be set with a knob on the back. A frequency can be entered using the AM and FM buttons and the number keys. The receiver then tunes to the requested frequency by pressing "execute." Stations can be stored on a number key by simultaneously pressing "Enter" and a number between 0 and 9. Manual tuning is possible using the arrow keys. A red light to the right of the dial will illuminate when the tuning is correct. The time and the turn-on time can also be set. The original price was DM 560.
