Sony ICF 5900: Classic meets excellence

Sony ICF-5900 — Vintage Multi-Band Portable Radio The Sony ICF-5900 (also sold as the ICF-5900W “Skysensor”) is a classic analog portable radio receiver from the 1970s, known for its robust build, world-band reception, and vintage styling. It was designed for serious listening on AM, FM, and shortwave (SW) bands. Key Features Multi-Band Reception • FM broadcast band: ~87.5–108 MHz (varies by version). • MW (Medium Wave / AM): ~530–1605 kHz. • Shortwave: Three bands covering roughly 3.9–28 MHz for listening to international broadcasts. Tuning & Circuitry • Analog tuning with a bandspread dial for more precise tuning on shortwave. • Dual-conversion superheterodyne design enhances sensitivity and selectivity, especially on shortwave and FM. • Includes a crystal calibrator for more accurate frequency reference. • BFO (Beat Frequency Oscillator) for receiving SSB and Morse code signals. Audio Controls & Output • Built-in speaker with separate bass and treble controls. • Tuning/Battery meter on front panel for signal strength and battery monitoring. • External jacks for headphones and optionally tape recorders (varies by model). Power & Build • Runs on three D-cell batteries (≈4.5 V) or external DC/AC adapters. • Fairly large and heavy compared to modern portables (~2.2 kg). • Rugged plastic case with classic analog dial and control layout. Performance & Use This radio was popular with shortwave listeners and hobbyists because of its strong reception and tuning accuracy for its era. It performs well for FM and shortwave broadcasts, though the medium-wave band is sometimes described as less sensitive compared to dedicated MW portables.
