Manufactured by Sony, Tokyo.
In 1983, Sony launched the ICF-7600A as successor to the first miniature multiband shortwave travel radio ICF-7600. In a cabinet that had an almost identical appearance, Sony now managed to accommodate a complete analogue double conversion receiver.
- ICF - 7600A, Japanese version, VHF range 76 - 108 MHz
- ICF - 7600AW, international version with FTZ-compliant VHF range 88 - 108 MHz
- 120 x 190 x 32 mm, weight 0.5 kg
With 120 x 190 x 32 mm, the Sony ICF-7600A has almost the same dimensions as its single conversion predecessor. The plastic cabinet is also black coloured, but the set has 7 spread shortwave bands, the switch-off button is marked in green.
The left half of the front panel is taken up by the loudspeaker with its flat design. Most of the right half of the front panel is taken up by the dial window with the vertically arranged band spread dials for the 49, 41, 31, 25, 19, 16 and 13 m shortwave bands and the dials for mediumwave and VHF printed directly on the cabinet. Below the dial window are the range keys for short-, mediumwaves and FM broadcast band, and a slide switch below the corresponding dials selects one of the seven shortwave bands. The small POWER OFF button is marked in green, it switches the set off, the button can be pushed backwards as a transport lock and thus prevents the Sony from being switched on unintentionally in the luggage. A small red LED serves as a rudimentary field strength indicator.
In the middle between the loudspeaker and the frequency dials are the volume control, which is designed as a sliding potentiometer, and the switchable tone control.
The tuning knob on the right side of the unit can be operated without any backlash. The Sony set has a tuning accuracy of about 10 kHz in the lower frequencies and about 20 kHz in the higher frequency bands.
On the left face of the set, there is a 6 V power supply socket, earphone and tape line out. The four UM-3 AA cells required for operation are inserted on the back.
The Sony ICF-7600A is just as easy to operate as its predecessor. Press the range key, select the shortwave band with the slide switch and start searching for stations in the region of the next 50 kHz mark. The Austrian Broadcasting Corporation on 6155 kHz can be found in the region of the 6.15 mark. Unfortunately, the tropical bands and the 21m band are not covered, anyway most of the out-of-band frequencies are left out.
Single-sideband or even radioteletype reception is not possible with the miniature radio. Only the microprocessor controlled ICF-7600D (D stands for digital), which was also introduced in 1983, is a set with similar dimensions that is capable of SSB reception.
Double conversion superhet, analogue technology.
The set is equipped with semiconductors.
