ATS-20 Radio: Quick Start & Operation Manual

1. What’s in the Box? (Typical)

• ATS-20 radio unit
• USB-C charging cable (5V only – do not use fast chargers)
• Removable 18650 lithium battery (may be included or sold separately)
• Small wire antenna (for shortwave)
• User manual (often poorly translated)

Firmware Updates: Many ATS-20 radios run on Arduino-based code. If your device feels "buggy," the enthusiast community often releases updated sketches that improve stability and add features.

First Impression: The ATS-20 feels premium. The rotary encoder (knob) is the primary control. It has a bright 1.8-inch or 2.0-inch TFT color display. Do not lose the tiny reset button pinhole—you will need it. ATS-20 Radio: Quick Start & Operation Manual 1

• The radio unit (aluminum alloy case)
• 18650 battery (or a plastic spacer if not included)
• USB-C charging cable
• Small "cheat sheet" manual (very basic)
• Optional: Antenna adapter (SMA to 3.5mm)

Tuning Methods

• Coarse tuning: Fast spin of tuning knob.
• Fine tuning: Press M once → smaller step size (e.g., FM: 0.05 MHz).
• Direct frequency entry: Not available on most ATS-20 models – use knob only.

• Specifications: Frequency ranges, output power, modulation types, sensitivity, selectivity, impedance, power requirements, and environmental ratings must be precise. The manual should state measurement conditions (e.g., antenna type, supply voltage) so users can replicate performance.
• Controls and Indicators: Each knob, switch, and LED should be described with function and expected behavior. The manual should explain band selection, volume/squelch, mode (AM/FM/SSB/CW) settings, and any menu-driven features.
• Operation Procedures: Step-by-step instructions for transmit/receive, frequency tuning, memory operations, scanning, and using any data interfaces are essential. Examples of typical workflows (e.g., making a call, storing a frequency) are helpful.
• Connectivity: Descriptions and pinouts for microphone, external speaker, antenna connector, power connector, and accessory ports (data, PTT) must be included. Wiring diagrams for common setups (vehicle installation, base station) add value.
• Maintenance and Calibration: Routine care (cleaning, connector checks), fuse replacement, and battery handling should be covered. For technical users, alignment procedures, calibration points, and test equipment requirements (signal generator, oscilloscope, dummy load) are important.
• Schematics and Parts: Circuit diagrams, PCB layouts, component values, and parts lists enable repair. Safety warnings about high voltage sections and ESD-sensitive parts should accompany service information.
