This is a used Sony ICF-7700 Portable Shortwave Receiver sold in non-working condition for Parts or Repair.

Please see photos for actual condition if item. All functions and band ranges seem to work, including making static noises as you tune around, but I have not been able to receive any station. Includes power adapter. Missing battery compartment door.

General information:
Digital shortwave portable (dual conversion)
Coverage: SW in 12 bands (90m to 11m), MW (3 kHz steps: 531 - 1602 kHz; 5 kHz steps: 530 - 1700 kHz), LW (150 - 285 kHz), FM (76 - 108 or 87.5 - 108 MHz)
5 kHz steps on SW, 3kHz/5kHz on MW, 3kHz on LW
3 x 5 presets (5 for LW/MW, 5 for SW, 5 for FM)
No fine tuning
No external antenna jack
Rec out jack
Alarm and sleep functions
IFs of 10.71 MHz and 455 kHz ("normal" dual conversion with narrow xtal filter on 1st IF, similar to ICF-SW33 or ICF-SW30, but with unbalanced 1st mixer as in ICF-7601 or ICF-SW35)
Switched tank circuits for antenna tuning / bandpass filtering for the individual shortwave bands, ferrite rod for MW/LW is untuned (preamp w/ feedback as in SW7600 etc.)
AM IF filter: IFT + ???455IT, possibly a 6-element CFWS, 4 kHz nominal
FM IF filters: 2x SFE10.7MA (the usual 280 kHz barn doors)
Receiver part is based around a CXA1031M, apparently something proprietary that is likely to be quite similar to the all-in-one CXA1019 and CX20091/CXA1191 ICs (compared to the latter, the functionality and pinout are identical)
3-gang FM frontend
Frequency synthesizer / microcontroller: µPD1715G
Audio output: 400 mW at 10% THD
Spec'd battery life: 19 hours with Sony SUM-3 (NS) zinc chloride cells
Dimensions/weight: 192 x 117 x 32 mm, 610 g (incl. batteries)
Produced: 1987 ... 1989
Original list price in Germany: DM 498
