✅The radio is original, Taiwan, its agent is Zagzoug and Al-Mutabali. It is no longer manufactured. It works on electricity and batteries. A 9-volt charger is included with the radio ✅ . 🌕 Sangean Radio Model ATS-803A, Multi-Band Digital. . 🔴 The Sangean ATS-803A radio is considered a classic digital multi-band receiver (World Band Receiver) released by Sangean in the mid-1980s. It is one of the famous devices among long-range radio reception enthusiasts (DXers). 🌕 Frequency Bands: Supports FM, AM (MW), Long Wave (LW), and Shortwave (SW) with an advanced digital tuning system (PLL Synthesized). Features: It has a digital display, memory buttons for saving stations, precise tuning indicators, and the ability to receive mono/stereo and single sideband (SSB/CW) broadcasts. Power: It operates either by an external power adapter (9V) or by portable batteries. The Sangean ATS-803A radio is characterized by its professional and excellent performance, making it one of the most prominent competitors to Sony's venerable devices in the 1980s and 1990s. Here is a comprehensive breakdown of its sound quality and channel reception capabilities: 1. Channel and Frequency Reception (Reception) Dual Conversion System: The radio relies on a dual-conversion superheterodyne circuit for shortwave, medium wave, and long wave. This feature prevents interference and image frequencies, ensuring clear reception of distant stations. Comprehensive Shortwave Coverage (SW): It covers the entire band without any gaps from 150 kHz to 29.999 MHz, divided into 12 expanded bands to facilitate finding international broadcasts. Single Sideband (SSB) Feature: It has a switch to select Upper Sideband (USB) and Lower Sideband (LSB) in addition to a fine-tuning knob (BFO / Clarifier). This feature allows you to receive amateur radio (Ham Radio) communications, Morse code signals, and marine and air traffic. High Selectivity (Wide/Narrow): This addition specifically distinguishes the "A" version from the older version; it allows you to narrow the band (Narrow) to isolate two interfering stations on very close frequencies, or widen it (Wide) for the best sound quality from strong stations. RF Gain Control: A manual rotary knob allows you to reduce the reception sensitivity to protect the device from digital saturation or distortion when receiving a very strong and close station. 2. Audio & Signal Quality Digital Stability (PLL Synthesizer): Thanks to the digitally phase-locked loop processor, the radio does not suffer from "frequency drift." Once the number is entered or the station is tuned, the signal remains perfectly stable without distortion. Signal Strength Meter: The device's screen is equipped with a digital indicator that accurately displays the station's reception strength, helping you to orient the built-in telescopic antenna (which extends up to 1.38 meters) for the best reception angle. Amplification and Sound Quality: The radio has a relatively large internal speaker that produces a warm and deep sound, with independent sliders to control bass and treble levels to customize the sound to your liking. High-Fidelity FM Stereo: When listening to FM waves, the radio supports true and pure stereo outputs, which you can enjoy through the input.
